A device and method for online vacuum degassing of aluminum liquid

Background technique

The gas element in the aluminum liquid is mainly hydrogen, and its content is generally greater than 0.35ml/100g. During the solidification process of the aluminum liquid, it precipitates and forms bubbles. Once captured by the solidification front, pinholes, pores, looseness, etc. will be formed in the ingot. Casting defects lead to scrapped ingots or subsequent processing defects. According to reports, casting waste caused directly or indirectly by excessive hydrogen concentration in liquid aluminum accounts for more than 40% of the total waste. As the application scope of aluminum alloy products becomes wider and wider, the attention to the internal structure of aluminum alloy ingots has become more and more important.

Tightness requirements are also getting higher and higher. Reducing the hydrogen content in molten aluminum plays an important role in improving the quality of aluminum alloy ingots. In order to reduce the hydrogen content in the aluminum liquid, domestic aluminum processing enterprises currently use a degassing device that rotates and sprays inert gas. This type of traditional rotating spray degassing device places a graphite rotor in the aluminum liquid in the launder system and sprays the inert gas through it. The rotating graphite rotor breaks the bubbles and forms small bubbles, which increases the contact area between the inert gas and the aluminum liquid and the bubble floating time. Since the hydrogen partial pressure of the inert bubble is low, the hydrogen atoms in the aluminum liquid form hydrogen molecules and enter the inert bubble. Within, the bubbles float up and are removed to achieve the purpose of hydrogen removal. However, when domestic enterprises produce high-end aluminum alloys, they still need to mix a small amount of toxic gas chlorine into the inert gas to ensure high degassing efficiency. This poses great safety hazards and environmental pollution risks, and the hydrogen content of the aluminum liquid after degassing mainly depends on The hydrogen concentration of the incoming aluminum liquid before degassing is unstable, and the degassing efficiency of the aluminum liquid is unstable. Therefore, the incoming aluminum liquid must be pretreated before online degassing, which increases the process cost and production cycle.

Alcoa considers closing Norway's Lista aluminum smelter completely

According to foreign media reports, due to rising electricity prices, international aluminum giant Alcoa is considering closing its Lista aluminum smelter in southern Norway.

Alcoa Energy Director Ole Lofsnaes wrote in a letter to the Norwegian Ministry of Petroleum and Energy: "The Lista aluminum smelter is still struggling to make a profit, although it will reduce some capacity in 2022 due to high electricity prices. Struggles, 2024 is expected to be a more difficult year. For this reason, Alcoa is now considering all possible future scenarios for the Lista aluminum smelter, with complete closure of the aluminum smelter being one of the scenarios being considered. " Last August, when electricity prices reached record highs, Alcoa reduced some capacity at its Lista aluminum smelter. In February this year, the company announced that it would reduce the factory's production capacity by 30% throughout 2023. Alcoa Energy Director Lofsnaes said it was crucial for the company to sign a new power supply agreement as soon as possible to protect it from high spot prices in the future. The Norwegian government plans to cut carbon dioxide offsets for industrial companies starting in 2024, which will also compound the problems at the Lista aluminum smelter. It is understood that Alcoa's Lista Aluminum Smelter in Norway has an annual primary aluminum production capacity of 94,000 tons and a total of three electrolytic aluminum production lines. One of the production lines was closed last year. Alcoa also operates an aluminum smelter in Mosjoen, northern Norway, with an annual production capacity of 200,000 tons of primary aluminum. Spot electricity prices in southwestern Norway have averaged €78.79/MWh so far this year, well below the 2022 average price of €211.28/MWh but still higher than the average price in northern Norway of €26.91/MWh.

Minmetals Nonferrous Metals North China Aluminum Co., Ltd. made overall plans to weather the floods safely

Since July 29, affected by typhoon "Dusuri", the Beijing-Tianjin-Hebei region has continued to receive heavy rainfall. Due to factors such as extremely heavy rainfall and flooding of upstream rivers, the risk of waterlogging in Zhuozhou City, Hebei Province has intensified, and the flood control situation is very severe.

In this regard, Minmetals Nonferrous North China Aluminum Co., Ltd. (hereinafter referred to as North China Aluminum) Prevention and Rescue Headquarters responded quickly, "a game of chess" to build a safety barrier. During the heavy rainfall in the early stage, in order to ensure the safety of the project construction, cadres and employees added generator sets and multiple drainage pumps in the rain, dug through the cofferdam of the reservoir, and dug two gaps in the wall, which resolved the rainwater backfilling time and time again. Entry risk. At the same time, in response to the rapid rise in the water level caused by the flood discharge of the upstream river, the flood control team urgently filled more than 3,000 bags of flood control sandbags, built a flood control line, and strictly guarded against the flood. All the personnel involved in flood control and flood fighting performed their duties and fought day and night to ensure the safety of the company during the flood.

The normal discharge of rainwater from the storage tank is the key to flood control in the new material plant area of North China Aluminum. For this reason, the flood control personnel of the Ministry of Equipment and Energy carried out maintenance work overnight, entered the 8.5-meter-deep reservoir to disassemble and clean the pump, and fished out the sundries in the pool. After the one-time return installation, the water pump starts to run normally, which ensures the smooth drainage of the reservoir.

North China Aluminum Yinfa Company is responsible for inspecting and cleaning the flood discharge pool in the factory area. During the flood control period, large forklifts were used to dig trenches and divert water, and special personnel were sent to guard the work site, completing a diversion ditch about 100 meters long, 1 meter wide and 0.8 meters deep , Properly expand the capacity of the flood discharge pool, which has played a positive role in the drainage and flood discharge of the Hualv New Material Factory.

The danger intensified. The water level of the reservoir in the new material factory area of North China Aluminum was too high, and the accumulated water overflowed to the industrial road. The factory area faced the risk of rainwater backflow. The situation was critical, and the General Affairs Department quickly communicated and coordinated with the local municipal government to obtain support, and cooperated with the 22nd Metallurgy to mobilize large-scale excavating machines overnight to start operations, decisively opened up the cofferdam between the large and small reservoirs and the south and west walls, and achieved The accumulated water is discharged outside, eliminating the risk of rainwater intrusion.

Danger is an order. The manufacturing department organized more than 30 party members and cadres and backbones to rush to the designated area to participate in flood control work, filled more than 320 sandbags, reinforced and blocked more than 20 large and small doors, and 9 transformer ventilation holes; dispatched a commando team composed of 6 party members and backbones Go to the outside of Huabei Aluminum New Materials Factory to support the excavation of drainage ditches.

Zhuoshen Company organized party members, cadres, and employees to temporarily put down production tasks, and urgently filled sandbags at the west gate of the North China Aluminum Factory. The flood control commando was stationed in the factory, strengthened on-duty inspections, prepared for the timely evacuation of personnel in the event of floods, organized employees to fight against floods, and ensured a safe flood.

Under the strong leadership of the Minmetals Nonferrous Metals North China Aluminum Flood Control and Rescue Headquarters, the flood control team members charged forward and went all out to fight on the front line of flood fighting and rescue, and practical actions ensured the normal and stable production and operation of the company and project construction.

Documentary of Yunal Aluminum Haixin's practice of green development

Paint the background of green, low-carbon and high-quality development with the attitude of struggle

——Yun Aluminum Haixin's practice of green development documentary

The report of the 20th National Congress of the Communist Party of China pointed out that it is necessary to accelerate the green transformation of the development mode, implement a comprehensive conservation strategy, develop green and low-carbon industries, advocate green consumption, and promote the formation of green and low-carbon production methods and lifestyles. This major strategic decision-making arrangement provides a fundamental basis for promoting the country to achieve the goal of carbon peaking and carbon neutrality.

As the vanguard of the green aluminum production capacity of Yunalco, Yunalco Haixin Aluminum Co., Ltd. (hereinafter referred to as Yunalco Haixin) has always been adhering to the development concept of "green water and green mountains are golden mountains and silver mountains", and "responsible Chinalco, green Haixin" "Incorporated into the whole process of the company's development planning, business decision-making and production activities, continuously increase the proportion of green and low-carbon development, deeply promote green manufacturing, build low-carbon factories, promote clean production, pursue energy saving and consumption reduction, strengthen technological innovation, and promote high-tech quality development.

Pollution reduction and carbon reduction: clean production has achieved remarkable results

Cleaner production plays an important role in promoting the synergy of pollution reduction and carbon reduction, and helping to achieve carbon peaking and carbon neutrality. In order to create a green production environment and reduce the pollution discharge of production water, so as to achieve the goal of driving high-quality development with a green engine, Yunaluminum Haixin has built a set of initial rainwater collection ponds with a daily processing capacity of 2,000 cubic meters to achieve preliminary of water treatment. In addition, Yunlu Haixin has also built two sets of domestic sewage treatment systems with a daily treatment capacity of 480 cubic meters and one set of production wastewater treatment systems with a daily treatment capacity of 250 cubic meters, further improving the rain and sewage diversion system inside the factory. The production wastewater treatment system adopts technologies such as multi-media filtration, ultrafiltration, reverse osmosis, and MVR evaporation and crystallization. Reuse of domestic water, plant greening, to achieve zero discharge of sewage.

In accordance with the construction requirements of the green hydropower aluminum processing integration project, Yunal Aluminum Haixin has also built 6 sets of flue gas purification systems and 40 sets of single-machine bag dust collection systems in the factory area. Through the use of alumina dry purification adsorption and semi-dry desulfurization technology , After the electrolytic flue gas is purified, the emission concentration is much higher than the national emission standard, and the pollutants are ultra-low emission. At the same time, Yunaluminum Haixin vigorously promotes the harmless disposal and resource utilization of hazardous waste. In July 2020, the carbon slag resource utilization system with an annual processing capacity of 7,000 tons will be completed and put into operation. It adopts non-secondary pollution treatment technology to realize the Recycling, reduction, and harmless utilization of hazardous waste. Since the start of the project, more than 19,000 tons of carbon slag have been processed, and the output value of recycled electrolyte with a purity greater than or equal to 98.0% has reached more than 9,000 tons. Low-emission low-carbon products are manufactured, and reliable, safe, green and environmentally friendly primary aluminum and aluminum alloy products are created.

Resource recycling: energy saving and consumption reduction

Under the guidance of the national "dual carbon" target policy, Yunal Aluminum Haixin gives full play to the leading role of science and technology, stimulates the internal power of green innovation, focuses on "energy saving, consumption reduction, pollution reduction, and efficiency improvement", and achieves low energy consumption and high efficiency through refined management , actively using the latest pollution reduction technology system, focusing on improving the quality of circulating water sources, through continuous improvement of energy consumption online monitoring system, online monitoring, and remote operation, intelligent water control is achieved, and the efficiency of recycled water is greatly improved. According to statistics, from 2021 to 2022, the water resource recycling rate of Yunnan Aluminum Haixin will reach 90%, effectively realizing zero discharge of sewage. In August 2022, the company was awarded the "Yunnan Provincial Water-saving Benchmarking Enterprise", and ranked first in the electrolytic aluminum industry with an outstanding water intake of 0.18 cubic meters per ton of aluminum, and ranked second overall.

Constrained by the "dual control" policy of energy consumption, Yunal Aluminum Haixin actively changed its development thinking, took the practice of ecological development, and built a green Haixin as the main line, carefully and meticulously managed from the source, and strictly controlled the output of energy consumption , by exploring the recovery and utilization of waste heat from electrolysis flue gas, recovering waste heat from the flue gas purification system, and heating cold water into hot water, it satisfies the use of office buildings, shift dormitories, canteens, heating, etc. in the factory area and living area to the greatest extent. While life is convenient, it also exerts great economy and applicability. In 2022, Yunaluminum Haixin will provide about 36,000 cubic meters of hot water throughout the year, the direct current power consumption per ton of aluminum will be reduced by about 68 kWh year-on-year, and the auxiliary power consumption per ton of aluminum will be reduced by about 120 kWh year-on-year. A solid foundation has been laid for achieving the goals of carbon peaking and carbon neutrality.

Green Technology: Technological innovation is becoming more and more perfect

Innovation promotes development, and technology leads the future. As a leading scientific and technological innovation enterprise in the electrolytic aluminum industry, Yunlu Haixin has always attached great importance to research and innovation in the field of project technology. Through government support and talent introduction, it has successively participated in the "Key Technology Research and Technology Project for Efficient Recycling of Aluminum Resources" "Development and application of 7,000 tons of carbon slag thermal treatment technology", "Research and development of aluminum electrolytic semi-dry desulfurization technology" and other projects have achieved phased technological breakthroughs, integrated multiple innovative technologies, and achieved great success in R&D, production, and quality control Several aspects have been effectively integrated with production and operation.

During the opening of the tank, due to process requirements, the tank cover door is frequently opened and closed, resulting in fugitive emissions. The fine particle dust cannot be absorbed through the desulfurization tower air duct in a timely and sufficient manner, and diffuses to the external space through the roof ventilator. In order to reduce the environmental impact caused by fugitive emissions, Yunaluminum Haixin adopts the advanced technology of micron-level dry fog dust suppression. By arranging dry-fog nozzles along the roof ventilator, it sprays micron-level dry fog with the same particle size as the dust The loose dust is condensed and collected, and its settlement is accelerated to achieve the purpose of dust suppression. After the system was put into operation, the dust suppression rate reached 90%. Compared with the start-up period of the first-phase electrolyzer of the project, the fugitive emissions in the factory area and the external environment have been significantly improved, greatly reducing the environmental risk during the start-up period.

In recent years, Yunaluminum Haixin has devoted itself to the research and development of new energy-saving equipment, and put it into trial operation at a 10 kV air compressor station. Through the comparison of one month's operation data, the electricity consumption of Yunallu Haixin has been reduced by about 10% compared with that before the equipment is used, which can save more than 3.8 million kWh of electricity every year. By comparing the use effect of motor power savers in benchmarking enterprises, the Yunlu Haixin R&D team boldly researched and tried to select suitable pilot sites to install power savers on 22 motors. After the test is up to standard, it will be promoted and used throughout the company.

The rise of green, the future can be expected. Green, low-carbon and sustainable development has become an important trend for Yunal Haixin to move towards high-quality development. In the future, under the guidance of the spirit of the 20th National Congress of the Communist Party of China, Yunal Haixin will actively fulfill the sacred duties of ecological civilization construction and ecological environment protection, continue to explore on the road of sustainable green development, and integrate the concept of green development into every production In the session, with the posture of struggle, we will paint the background of green, low-carbon and high-quality development, and write a new chapter in Haixin's green development for building the southwest base of Chinalco's aluminum industry worth 100 billion yuan.

【Expand the application of aluminum (116)】Aluminum can be used in transmission poles and towers

At present, most of my country's transmission towers are made of steel, which has been used for more than 200 years. However, the disadvantages of iron towers are that they are dense, heavy and inconvenient to transport. Especially in mountainous and plateau areas, transportation, installation and maintenance are difficult. It is laborious and must be maintained regularly, otherwise it will rust and even be damaged. But if the steel it uses is replaced by aluminum, it will be different. In the past, I was worried that the strength of aluminum was not high, but now it is not a problem to manufacture it with ultra-high-strength aluminum alloy. This alloy has a high enough strength that it is more than enough to make transmission and distribution towers, and it is fully capable.

The State Grid Corporation headquarters management science and technology project "High-strength aluminum alloy transmission tower design and processing technology and standardization research" led by China Electric Power Research Institute (hereinafter referred to as EPRI) passed the acceptance inspection. Conventional transmission towers are made of steel and must be hot-dip galvanized to prevent corrosion. However, galvanizing is not good for the environment. At the same time, the galvanized layer will fall off after a long time of use, and it is not easy to transport materials when erecting towers in rugged mountainous areas.

Therefore, the project team explored the use of high-strength aluminum alloy materials to replace traditional steel materials, carried out technical research and development of high-strength aluminum alloy materials in transmission towers, formed high-strength aluminum alloy tower raw materials, and realized the processing of tower materials without galvanizing and reducing the quality by nearly 45%.

The results of the project have passed the acceptance test in December 2022 and can be used for material selection, structural design and product processing of aluminum alloy transmission towers.

The Institute of Power Transmission and Distribution Engineering of the Chinese Academy of Sciences used the research results of the project to carry out the true type test of China's first self-supporting aluminum alloy pole tower. The test tower uses 7A21 and 7A41 high-strength aluminum alloy materials, and adopts the new YT section profile newly developed by the Electric Power Research Institute. The test tower is equipped with 60 strain measurement points and 12 displacement observation points, and the strain measurement and displacement observation of the important components, nodes and overall deformation of the aluminum alloy tower are carried out throughout the process. There are 6 working conditions in the test, and the overload test of the 90° windy condition is carried out. The test successfully verified the rationality of the design method and processing technology of the high-strength aluminum alloy tower.

The research team of the Chinese Academy of Sciences and other projects explored a new route for the application of high-strength aluminum alloy materials in power transmission self-supporting towers, and proposed new solutions to solve the problems of mountainous tower material transportation, galvanizing pollution and anti-corrosion maintenance, and promoted the tower industry in new material research and development, Technological progress in design, scientific research, processing, and construction.

7A21 and 7A41 alloys are Chinese brand alloys, and their original alloys are 7021 and 7041, which means that the composition and properties of 7A21 are equivalent to those of 7021 alloys, and the composition and properties of 7A41 alloys are equivalent to those of 7041 alloys. 7021 is an Al-Zn-Mg alloy, and 7041 is an Al-Zn-Mg-Cu alloy. According to the habits of the aluminum industry, they should be called super-strength alloys rather than high-strength aluminum alloys. 7021 alloy is an American alloy, registered in the Aluminum Association of America in 1976, its calibration composition (mass%): Si0.25, Fe0.40, Cu0.25, Mn0.10, Mg (1.2 ~ 1.8), Cr0 .05, Zn (5.0-6.0), Ti0.10, Zr (0.08-0.18), other impurities single 0.05, alloy 0.15, and the rest Al. 7041 alloy is a French alloy, registered in the American Aluminum Association in 2008, its calibration composition (mass%): Si0.15, Fe0.25, Cu (0.40-0.9), Mn0.04, Mg (1.5-2.3 ), Cr 0.04, Zn (5.7-6.7), Ti0.06, Zr (0.05-0.12), other impurities 0.05 individually, 0.15 in total, and the rest Al. This is a very clean alloy with very low content of impurities Si and Fe.

On January 12 this year, the world's Z tallest transmission tower with a height of 385 meters was successfully capped in Jiangsu. The iron tower is an important part of the 500 kV power transmission line project from Taizhou Fengcheng to Wuxi Meili. After the project is completed, about 28.9 billion kwh of clean electricity can be sent from the north bank of the Yangtze River to the south bank of the Yangtze River every year, meeting the needs of about 8 million households. daily electricity needs.
