    Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy. The heat for this reaction can come from several forms but typically from the electric arc formed between the tips of electrodes in the bottom of the furnace and the furnace hearth. This arc creates temperatures of about 2 800 °C (5 070 °F).
