WO2011045755A1 Ferrochrome alloy production Google
Ferrochrome alloy is produced by smelting chrome ore, fluxing agents and carbon reductants in a DC arc or AC submerged arc furnace. Tapping of molten slag and metal from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the hearth of the furnace, a tap hole is drilled open and a stream of molten metal
Analysis of Transport Phenomena in Submerged Arc Furnace
