Dec 13 2018nbsp018332This reduction process is carried out in a furnace called blast furnace. The manufacture of iron is based on the principle of reduction of iron oxide with carbon monoxide. This reduction process is carried out in a furnace called blast furnace. Iron manufacturing process pig iron cast iron and wrought iron December 13 2018
The blast furnace process is primarily used in the carbothermic reduction of oxides such as iron inc and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently rich iron ore andor iron oxide pellets formed from concentrate can be added directly to a blast furnace see Iron Production.

A blast furnace is a special type of furnace.They are used to make iron from ore.Blast furnaces are very large. They can be up to 60 metres 200 ft tall and 15 metres 49 ft in diameter.The blast furnace is the biggest chemical reactor.Blast furnaces are also called high ovens.. A blast furnace is usually built with a steel case and bricks made of magnesia inside the case.

Pig iron is a solid form of hot metal obtained from iron ore or scrap recycling and it is processed with blast furnace or electric arc furnace. Pig iron is used as a raw material for iron steel making and most of this material was imported. The pig iron from scrap availability is limited so that iron steel producers and foundry industries

In the blast furnace liquid pig iron is produced from processed iron ores in a continual smelting process. The blast furnace generates heat of over 2000 degrees Celsius in order to melt iron from the iron ore. To reach this temperature coke is used as fuel and the fire inside the furnace is fanned with hot air at 1400 degrees Celsius.

Apr 01 2013nbsp018332Pig iron Pig iron is an intrmediate product of a steel plant produced during smelting of iron ore in a blast furnace. Iron ore is reduced by coke using limestone and dolomite as flux for removal of impurities. The resulting liquid iron hot metal when cast in the pig casting machine produces pig iron. Fig 1 shows pig iron.
