High-carbon and charge chrome alloys are generally produced in the conventional smelting process by carbothermic reduction of ferrochrome ores using AC submerged-arc and DC open-arc electric furnaces. In AC submerged-arc furnaces, the energy to the furnace is predominantly supplied in a resistive heating mode.
