#Bessemer Converter

[myriad--starlings]

When the men have departed, Henry orders tea, and we drink it sitting on either side of the fireplace. He wishes to talk over the day, and I take it, echoing his words when he wants me to, confirming his opinions. I am a mirror for him, and I have learned how to show the desired reflection.

I have learned I am no more than that. In my mind’s eye, the molten steel from the Bessemer converter pours into the torn open mouth of the grinder, blood and metal merging.

— Hungerstone, Kat Dunn

Did you know? 🤔

There are currently 1712.1 million tons of steel being used in the world today.

During the Technological Revolution and the Second Industrial Revolution, Henry Bessemer invented a method to mass-produce steel called the Bessemer process.

Before, it used to take a full day to convert three to five tons of iron to steel, but with the invention of the Bessemer process, it only took under 20 minutes.

In 2018, 1712.1 million tons of steel is used, with 2.6 million tons used for railways and tracks and 18.8 million used solely for concrete reinforcing bars.

The storm was as alive as anything else, as alive as the ancient shale and sandstone mountains and the wind; as alive as the scorch and burn of the huge Bessemer converters and the slag-scabbed molten iron that rolled like God's blood across the slippery steel floors of the Cambria mills. And as perfectly mindless, as passionately indifferent. It had been born somewhere over Nebraska two days before, had swept across the plains and in Kansas spawned twister children who danced along the winding Cottonwood River and wiped away roads and farms. It had seduced Arctic air spilling off the Great Lakes and sired blizzards across Michigan and Indiana, had spoken its throaty poetry of gale and thunder throughout the Ohio River Valley, and finally, with its violent arms, would embrace the entire Mid-Atlantic seaboard.

Kingmakers: The Oligopsony of a Monopoly

The railroads are not run for the benefit of the dear public. That cry is all nonsense. They are built for men who invest their money and expect to get a fair percentage on the same. William Henry Vanderbilt, 1882

Prior to the railway boom American ironworks were beleaguered by sluggish growth. Demand by this new infrastructure however quickly distorted markets in favour of these foundries as iron and steel were sold at prices and volumes underwritten by government. How pregnant was this moment? At the outset of the 20th century upon J.P. Morgan’s consolidation of steel acquisitions the market capitalization of his new entity called U.S. Steel was the first to exceed a billion dollars in human history (Hessen 1972). The railroad monopoly became a de facto oligopsony for the vast consumption of durable metals between rails, rolling stock and bridges. In Washington’s economic arms race with Britain the government’s legislative capture gave rise to a captive market for these same manufactures. A staggering 90 percent of all Bessemer steel made in America between 1870 and 1890 flowed directly towards locomotives and their trappings (Misa 1998). The epithet of kingmaker aptly describes the clout shared by barons like Vanderbilt or Gould who themselves deputized steel magnates like Carnegie. The great blast furnaces of the Northeast were creatures of the railroads. The direct pipeline between the two conduced to the scale economies required for the exponential growth of each.

Yet something far more unique other than capital formation manifested in the symbiosis of both industries. Borne out of this marriage came a series of innovations in metallurgy due to the exigencies of railroads. Necessity is the mother of invention and ironmongers were tasked to create a material which would not succumb to the forces of attrition by the frequency and weight of locomotives. The industry thus espoused Darwinism whereby only the strongest metal survived whose properties demonstrated fewer and fewer impurities with each iteration. The first alternative of cast-iron exhibited a failure rate prohibitively high which risked frequent derailment. This iteration befit stationary loads akin to bridges but was too brittle for the stress tolerances of rails. Microcracks symptomatic of metal fatigue called for greater investment in the search for superior iron alloys with a greater lifespan. The next metal of choice to withstand the cyclical stresses of locomotives would be wrought iron known for its improved tensile strength. Yet despite its longevity this metal was also prone to fracture to the consternation of engineers. Recurrent failures spoke to the need to find more robust materials. The next quantum leap in technology was the introduction of puddled iron whose production method controlled for oxidation.

Despite this breakthrough being lightyears ahead of the pig iron of yesteryear it still remained an interim solution since it was liable to wear prematurely. The labour-intensive nature of this metal in its artisanal process meant quality irregularities continued to beset the service life of rails. Such limitations were anathema to the overhead of maintenance for railroad companies which sought to escape these recurring costs. Puddled iron therefore would be a stopgap until a final iteration materialized. Unlike its predecessors the technology of Bessemer steel won the hearts and minds of builders and financiers alike since its automation yielded consistent results. A controlled blast of air through an apparatus called a Bessemer converter produced high-quality grade metal at scale without fail. The pursuit of perfection thereby culminated in the mass production of steel which was well-nigh immune to fatigue from the rolling contact of locomotives. Railroads embraced this new technology with vim and verve as its removal of impurities within minutes generated greater output at less cost. A material upgrade of this sort saw this alloy become the sine quo non of railway construction to universal acclaim. Indeed America’s Industrial Revolution was essentially the legacy of Bessemer steel (Peters 1945).

Railroads were proving grounds for innovation in a race to source the best materials. New technologies in the production of alloys were not made in a vacuum but were functions of a pent-up demand for high-quality rails. The learning-by-doing of various foundries inexorably led to the apogee of Bessemer steel which was the gateway to industrialization. But no other industrialist exploited the captive market for rails more deftly than Andrew Carnegie who vertically integrated his operations to consolidate supply chains. His broad acquisitions of coal mines, iron fields and limestone quarries enabled a seamless transit of raw goods to their final destinations for steelmaking. As soon as Carnegie wedded such vertical integration to the Bessemer process he devastated his competitors with aggressive pricing. The brilliance of this market strategy can be laid bare as thus: the steel baron enriched himself by recouping his margins on the backend of procurement deals based on volume. Carnegie then shaped the purchasing behaviour of railroad companies with discounts in return for volume lest they forfeit premiums for the same product at other manufacturers. Always the shrewd negotiator, Carnegie cornered the market in a mutually beneficial alliance with railroad barons whose oligopsony created a monopoly within the steel industry.

The incestuousness between Carnegie and the railroad industry has no better proof than how his largest mill was a namesake for the president of the Pennsylvania Railroad. The Edgar Thomson Works founded in 1875 near Pittsburgh is eponymously named after the man. What differentiated Carnegie from his rivals was how he dared to capture the business of every major railroad company by creating an empire impervious to the price fluctuations of intermediate goods. What resulted was a closed-loop supply-chain to the detriment of competition. Such centralized control meant ore was sourced in Carnegie’s mines which was transported on his barges or trains which in turn was smelted in his mills. Absolute authority over the entire value chain of steel was the impetus behind the vast fortunes amassed. Carnegie was equally averse to the golden standard of business: diversification. Steel rails were a singular focus unlike other competitors vying for contracts to manufacture naval warships and castings. This specialization and the scale economies thereof locked out any other supplier in the hunt for marketshare. Corporate diplomacy was also an idiosyncrasy unique to the steel baron as he exploited philanthropy to court business like inaugurating the Carnegie Library of Homstead in the hometown of railroad executive William Donner.

to be fair the formula for gunpowder - that is to say, early gunpowder, not the smokeless variety or any of the more modern propellants - is pretty easy; you just need a source of nitrate, a source of carbon, and a source of sulfur. sure, maybe Random Person on the Street doesn't know this, but anyone with even a little knowledge of chemistry knows at least where to start, and after that it's a question of fiddling until you get the right ratios.

(personally I'd skip gunpowder and go right to guncotton, which has an even simpler recipe, but is less known in general)

the early modern sciences are reasonably knowable by a single person - it's why the term "Renaissance man" exists. the harder part is that just because you know the recipe doesn't mean you can build the infrastructure. e.g. a Bessemer converter is Large and Cumbersome, and while I could definitely sketch one from memory, that's still a long ways from being able to actually build one!

I've said it before but i think there's a whole bunch of piss to take out of the Reddit Guy Invents Gunpowder subgenre of isekai from an alt-science angle. If you have wizards and dragons and shit, there's no reason to assume that chemistry and physics work the same way. Florida Man injured in very avoidable phlogiston incident.
