Bessemer used phosphorus-free ores to create his steel. It is made with carbon and other compounds such as cast iron and wrought iron. Wrought iron is an iron that can be easily shaped and cast iron is a very firm type of steel that cannot be transformed. Steel is very solid and secure. Steel was scarce and wasn’t a helpful method of removing carbon from iron or to the specifications needed for steel. It was thought that cast iron could be converted to wrought iron by removing most of the carbon

to 2000 bc “True bronze (a copper-tin alloy) did not appear until around 3000 BC.”only being passed at first by iron and later by steel. Iron had been around as long as bronze but it offered little advantage as it was harder to form not as durable and didn’t keep an edge as well as bronzed did. its only plus side being that it was more abundant in the earths crust and easier to get. Iron on its own was nothing special but when carbon was added a truly amazing discovery was made‚ steel. Steel was

steel facilities or “mini-mills” that employed electric arc furnaces. Integrated mills used blast furnaces to produce hot metal typically from iron ore pellets‚ limestone‚ scrap steel‚ oxygen‚ assorted other metals‚ and coke (coke was produced by firing coal in large coke ovens and was the major fuel used in blast furnaces to produce molten iron). Melted iron from the blast furnace process was then run through the basic oxygen process to produce liquid steel. To make flat rolled steel products‚ liquid
