Types of iron and steel slag : NIPPON SLAG ASSOCIATION

Blast furnace slag is recovered by melting separation from blast furnaces that produce molten pig iron. It consists of non-ferrous components contained in the iron ore together with limestone as an auxiliary materials and ash from coke. Approximately 290 kg of slag is generated for each ton of pig iron.

How is Iron Refined from Ore? (with pictures)

Jul 29, 2019 · This is done contemporarily in the silo-like structure known as a blast furnace. The calcium in limestone bonds with the silicates in the ore, creating a material called slag, which floats on top of the pure liquid iron. The iron is periodically drained into a mold from a port at the bottom of the blast furnace, where it cools.

Basic oxygen process | metallurgy | Britannica

Basic oxygen process (BOP), a steelmaking method in which pure oxygen is blown into a bath of molten blast-furnace iron and scrap.The oxygen initiates a series of intensively exothermic (heat-releasing) reactions, including the oxidation of such impurities as carbon, silicon, phosphorus, and manganese.. The advantages of using pure oxygen instead of air in refining pig iron into steel were ...
