Furnaces For Iron Ore Reduction

The production of pig iron from crushing plant waste using .

In the blast furnace, iron ore or iron oxide is reduced by carbon dioxide (CO) formed as a result of carbon change in reduction environment . Cupola furnace modification is made by adding hot air (500–700 °C) coming from burning process, and it is referred to as hot blast cupola.

Midrex Process for Direct Reduction of Iron Ore .

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gas-based shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.

Direct reduced iron - Wikipedia

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high .
