5. The usage of ferrochrome
Chrome is mainly used to improve the intoxication and corrosion resistance of steel to make the surface of steel after it is oxidized to form strong adhesion oxide film. Then it stops being oxidized or decelerates being oxidized. Micro-carbon Ferro chrome is applied to making stainless steel, acid-resistant steel and heat resistant steel.
6. The Introduction of ferrochrome
Ferrochrome (FeCr) is an alloy of chromium and iron containing between 50% and 70% chromium. The ferrochrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. The production of steel is the largest consumer of ferrochrome, especially the production of stainless steel with chromium content of 10 to 20% is the main application of ferrochrome.
