Redsmelt process for ironmaking – IspatGuru

Apr 19, 2018Redsmelt process for ironmaking. Redsmelt is a new ironmaking process based a two reduction steps. These are (i) pre-reduction of iron bearing materials in a rotary hearth furnace (RHF), and (ii) smelting of the hot pre-reduced iron (DRI, direct reduced iron). Originally a submerged arc furnace (SAF) has been used for the second step. Get price

Aspects of SAF Smelting of Ferrochrom

SUMMARY As chromite ore moves through the submerged arc furnace during processing it passes through a number of reaction zones. In the upper furnace, zone 1, the chromite particulates are present as "loose charge" and product gas from the lower furnace consisting of principally CO and CO2 passes through this packed bed.

Control of Non

An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte, the latter usually being the product. The smelting process is carried out through high-power heating in electric arc furnaces [4]. Get price
