    How To Learn About High Carbon Ferrochrome In A Minute ...
    As of 2012, highcarbon ferrochrome with high chromium content was mostly smelted in a submerged arc furnace using a flux method. The basic principle of electric furnace smelting of high carbon ferrochrome is to reduce chromium and iron oxides in chrome ore with carbon. The starting temperature of carbonreduced chromium oxide to form Cr2C2 is 1373K.
