An Improved DC-Arc Process for Chromite Smelting

At present, the leading process for ferrochrome is that offered by Outokumpu [2]. This process essentially involves firstly the agglomeration (pelletizing) of the smelting recipe, followed by sintering, cooling, and screening. This sinter is thereafter reheated to 600-700°C and hot charged to a closed submerged electric arc furnace.
