The Modern Steel Manufacturing Process -

2020-8-21  Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle.

Steel Manufacturing Industry: Career, Outlook and ...

The least costly method of making steel uses scrap metal as its base. Steel scrap from many sources—such as old bridges, household appliances, and automobiles—and other additives are placed in an electric arc furnace, where the intense heat produced by carbon electrodes and chemical reactions melts the scrap, converting it into molten steel.
