Ningxia high-quality anthracite (unique low ash, low sulfur, low phosphorus, high fixed carbon, high calorific value) is calcined at 1200 ℃, with strong oxidation resistance, high mechanical strength, high chemical activity, high clean coal recovery rate and other characteristics. It is mainly used to increase carbon in steel making. Its function is to raise temperature quickly, with good effect and stable carbon absorption rate. It can be used to adjust the carbon content and oxygen content of molten steel, change its rigidity and toughness, and thus improve the nucleation ability of molten steel and the internal quality of billet.
