How to Produce Steel Plates? The Steel Plates

Jan 01, 2019 Primary Steel Making. 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
