What Is Electromagnetic Heating Roller

The electromagnetic heated roller is a type of heating transfer roller, which is made according to the principle of electromagnetic induction heating. Compared with the traditional oil heated roller and electric heating roller, the electromagnetic heating roller has the advantages of high temperature, good heating uniformity, and low energy consumption. The electromagnetic heated roller can be used in the surface calendering of various textiles and foaming materials, drying and stretching of films and various materials, etc.

Technical principle of electromagnetic heated roller:

Electromagnetic heated roller is a kind of roller which can heat itself in the continuous processing and production of industrial materials. The basic principle of its heating is to use the coil inside the roller to generate electromagnetic field, and by cutting the metal surface with magnetic line the roller can heat itself. The roller surface then exchanges heat with the material to be processed, and maintains the set working temperature of the roller through the temperature control system of the closed loop.

Compared to traditional heating roller, electromagnetic heated roller has several advantages:

1) The electromagnetic heating roller can work stably at a temperature of 350 ℃, breaking through the temperature bottleneck of traditional heating transfer roller, and meeting the temperature requirements of high-performance materials.

2) Because of its structural characteristics and excellent performance, the heating roller can keep the temperature of the roller surface accurately controlled during operation. It can also control the temperature change range according to the needs of special processes to ensure the quality of materials, reduce the waste of production caused by temperature changes;

3) It has remarkable energy-saving effect and cost of its maintenance is low. Compared with the traditional oil heated roller, the electromagnetic heating roller can be reduced by 50% or more. The complex heating equipment is abandoned, which can greatly reduce the heating power consumption;

4) When using the electromagnetic heating roller, there is little pollution, because it does not need heat transfer medium such as heat transfer oil or steam, which completely eliminates the pollution and potential safety hazards caused by medium leakage.
