High-carbon ferrochromium (containing 4 to 8% carbon), medium-carbon ferrochromium (containing 0.5 to 4% carbon), low-carbon ferrochromium (containing 0.15 to 0.50% carbon), micro-carbon ferrochrome (containing carbon 0.06 %), Ultra-fine carbon ferrochrome (containing carbon less than 0.03%), metallic chromium, silicon chromium alloy ferrochrome: ferrous alloys composed of chromium and iron, are the primary alloy additives for steelmaking. Refractory grade chromite, chromite for practicing chromite usually requires Cr2O340 ~ 50%, and the ratio of chromium to iron is greater than 2.8. In recent years, many "load-grade ferrochromes" containing 50% chromium have been produced using Cr2O3 and ores with lower chromium to iron ratios.
According to different carbon content, ferrochrome is divided into high-carbon ferrochrome including charging grade ferrochrome (C ≦ 10%), medium-carbon ferrochromium (C ≦ 4.0%), low-carbon ferrochromium (C ≦ 0.5%), micro Carbon chromium iron (C ≦ 0.15%), etc. Commonly used are silicon chromium alloys, iron chromium nitrides, and the like. Iron chrome is mainly used as an alloy additive for steelmaking, and once participated in the essence of steelmaking. To practice low-carbon steels such as stainless steel, it is necessary to use low- and micro-carbon ferrochrome, so the production of refined ferrochromium was once opened up. Because of the improvement of steelmaking skills, nowadays, when producing steel grades such as stainless steel by the AOD method (see the essence of the furnace), carbon ferrochrome (primarily charge-grade ferrochrome) is used to load the furnace. Micro-carbon ferrochrome adjusts the composition, so the current production of ferrochrome is focused on refining carbon ferrochrome.
