How is Steel Produced? | World Coal Association

The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace – Basic Oxygen Furnace. In the basic oxygen furnace, the iron is combined with varying amounts of steel scrap (less than 30%) and small amounts of flux. A lance is introduced in the vessel and blows 99% pure oxygen causing a temperature rise to 1700°C. The scrap melts, impurities ...

Extractive Metallurgy: Sponge Iron Making

Sponge Iron Making The process of sponge iron manufacturing involves removal of oxygen from iron ore. When that happens, the departing oxygen causes micro pores in the ore body, turning it porous. When the eventual product is observed under a microscope, it resembles a honeycomb structure, which looks spongy in texture. Hence the name sponge iron. The Main Raw Material are Primary ore ...

Chapter 73. Iron and Steel

For iron making, the essential feature is the blast furnace, where iron ore is melted (reduced) to produce pig iron. The furnace is charged from the top with iron ore, coke and limestone; hot air, frequently enriched with oxygen, is blown in from the bottom; and the carbon monoxide produced from the coke transforms the iron ore into pig iron containing carbon. The limestone acts as a flux. At ...
