Ferrochrome an overview ScienceDirect Topics
Chrome ore (an oxide of chromium and iron) is reduced by coke (and coal) to form the iron–chromium–carbon alloy The heat for the process is provided typically from the electric arc formed between the tips of the electrodes in the bottom of the furnace and the furnace hearth in very large cylindrical furnaces known as “submerged arc Chrome ore is converted to ferrochrome through intense metallurgical processing which includes smelting with carbon or silicon, utilising about 3 4 MWh per ton which involves the injection of pulverized chrome ore into a shaft furnace containing generators that produce high temperature ionized gases Plasma furnaces allow friable chrome The Impact Of Chrome Ore Exports on the Ferrochrome
