The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.

Limestone and Dolomite and their Use in Iron and Steel Plant

The process of iron making is the reduction of iron ore to produce iron. Iron ore normally contain gangue materials such asSiO2, Al2O3 along with S and P. Removal of these impurities is done by combining the gangue materials with CaO and / or MgO to form slag which consists of low melting point complex compounds such as calcium silicate ...

Pig Iron | International Iron Metallics Association

Pig iron is the product of smelting iron ore (also ilmenite) with a high-carbon fuel and reductant such as coke, usually with limestone as a flux. Charcoal and anthracite are also used as fuel and reductant.

The production of pig iron (high-carbon material) from these blast furnaces led to the development ... Limestone was used as a flux, natural gas was used as a fuel, and coal ... The Krupp–Renn ...

Pig Iron Production

In the sintering plant, sintering is produced from domestic ore, imported ore and limestone split. Sinter is used in blast furnaces together with coke, import minerals and other additives. 2 blast furnaces produce 3,500 – 4,500 tons of pig iron every day. The pig iron is transported to the steel plant by means of pipe pans.

Oxygen-Lime Converter Steelmaking Process | SpringerLink

an actual pig iron plant located in Lorraine region, in the North East of France. The plant considered produces pig iron from iron ores, mainly made of iron oxides, using a so-called ''first fusion'' route based on three main processes: the coking unit, the sintering unit and the blast furnace. The coking unit con-

Blast furnace slag is a combination of silica and other non-ferrous components of iron ore, ash from coke used as a reducing material, and limestone auxiliary material. Because its specific gravity is less than that of pig iron, during the heating process the molten slag rises above the pig iron allowing it to be easily separated and recovered.
