Steel production is dependent upon coal and coke in steelmaking. Metallurgical coke, or met coke, is manufactured from blends of bituminous coal in a heated distillation process resulting in a non-melting carbon. Coke is made by one of two processes: by-product or non-recovery, also known as heat recovery.
Steel is an alloy because it is a mixture of a metal (iron) with other elements (carbon and perhaps other metals too). Iron from the blast furnace contains about ~96% iron with ~4% of impurities including carbon, silica and phosphorus.In this state the cast iron is too hard and too brittle for most purposes.aCO3. 1  Iron ore is used to make iron and steel eg haematite and magnetite. 2  Iron is produced (extracted) in a blast furnace by reducing iron oxides with carbon and it is the carbon that removes the oxygen from the iron oxides the carbon is known as the reducing agent.
