The Making of Iron & Steel seaisi

2020-8-3  2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe)

How is Iron Refined from Ore? (with pictures)

To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To purify and strengthen iron, materials like coke are mixed in with it to remove oxygen. To coax the oxygen atoms away from the ore

An Overview of Steelmaking Process Steel Technology

To make steel, refining of iron needs to be carried out. In this process, the carbon content of hot metal is lowered, usually to less than 1% by an oxidation process in a steelmaking furnace. At the same time, alloying materials are added to the furnace to attain the required chemical composition of
