Blast Furnace Process Of Manganese . Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnacetype system, called a submerged arc oxides undergo carbothermal reduction in the furnaces
BlastFurnace Production Article about BlastFurnace
BlastFurnace Production the production of pig iron by the reduction smelting of iron ores or pelletized ironore concentrates in blast furnaces. It is a branch of ferrous metallurgy. History. Pig iron was known four to six centuries before the Common Era. The blastfurnace industry took shape as a result of the development of the blooming process—the
Blast Furnace Charge (Raw Materials for Steelmaking
1. QUALITY OF CHARGE MATERIAL: A blast furnace charge consists of coke, ore or sinter, and limestone. These materials must be in lumps of a certain size (4060 mm). Larger lumps prolong the process of reduction and fluxing. Smaller lumps block the fluegas passages and prevent a uniform descent of melting materials in the furnace. 2. IRON ORES: Ore is a metal bearing mineral.
