the process of making steel from iron ore

The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces. Making iron

Making steel ArcelorMittal

Making steel Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.

An Overview of Steelmaking Process Steel Technology

Steelmaking process involves the production of steel from iron ore and scrap. In this process, various impurities such as silicon, sulfur, nitrogen, phosphorus, and excess carbon are removed from the sourced iron. And, to produce different grades of steel, alloying elements such as nickel, manganese, chromium, and vanadium are added.
