During the production of ferrochrome, the heat created by electric arc furnaces, which reaches 5070°F (2800°C), causes coal and coke to reduce chromium ore through a carbothermic reaction. Once sufficient material has been smelted in the furnace hearth, the molten metal is drained out and solidified in large castings before being crushed.
