Brief introduction：
Ferrochrome is an important alloy additive for steelmaking, which is composed of chromium and iron. Chromite for smelting ferrochrome is generally required to contain Cr2O340 ~ 50%, and the ratio of chromium to iron is greater than 2.8. In recent years, a large amount of "charging grade ferrochrome" containing 50% chromium is produced, with ore containing Cr2O3 and low ratio of chromium to iron.
Low carbon ferrochrome is used in the production of low carbon structural steel, chromium steel, alloy structural steel. Chromium steel is often used to manufacture gears, gear shafts, etc. Chromium manganese silicon steel is often used in the manufacture of high pressure fan blade, valve plate, etc.
