Steelmaking starts with melting the raw inputs of iron ore, coke (produced by carbonisation of coking coal) and limestone together in a blast furnace. The resulting red hot molten iron contains 4-4.5% carbon and other impurities that make it brittle. So we need to move to further process the steel to achieve the desired quality.
