The Bessemer process pumps air through the iron to remove impurities. shropshirehistory.com The production of steel is done with the Bessemer process, which takes the molten pig iron and blasts ...

The mention of iron and steel making usually conjures up images of huge blast furnaces in which molten raw (pig) iron glows white-red, bubbling gently. Once it has reached the correct temperature and ...

At higher temperatures, the iron would absorb more carbon, melt, and result in a molten metal called cast or pig iron. Though the use of iron was already widespread in Europe and North America ...
