Ferrous metallurgy - Wikipedia

Ferrous metallurgy is the metallurgy of iron and alloys.It began far back in prehistory.The earliest surviving iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores from at least Greece to India, and more

Iron Ore Sintering Consumation In Blast Furnace

Iron ore sinter, constituting a major proportion of blast furnace burden, significantly impacts the blast furnace performance. The chemical composition of iron ore fines, particularly alumina, sinter basicity and sinter MgO together with the thermal conditions that sinter blends are subjected to play an important role in the formation of mineral phases in sinter.

Making iron & steel - blast furnace | ArcelorMittal

Before iron ore can be used, oxygen must be removed from it. Known as ‘reducing’, this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace process also produces two

The Blast Furnace (BF) plants were built for the production of large amounts of steel. The beginning of a melting metallurgical process is composed of the reduction of iron ore. In the BF, Cast Iron is produced and after that, by blowing oxygen in the converter, it is turned into the steel.

Iron Making | Coke (Fuel) | Blast Furnace | Free 30-day …

Blast Furnace The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

Creating Iron | HowStuffWorks

A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone coines with the silies to form slag.
