Recarburizer has important role when casting smelting, carburant has stable chemical properties, coefficient of thermal conductivity is high, the thermal expansion coefficient low, the wear-resisting performance is good, can greatly increase the dosage of scrap, reduce iron dosage or no use pig iron.Recarburizer to add time and method of casting smelting may also be affected.
Dispersion add method: according to the requirement of the matching or carbon content, along with the furnace charge to add in the electric part location, a layer of metal material, a layer of carburant, carburant melting slag not dozen.
Concentration add method: melting furnace charge only part of the melting of iron liquid under the condition of low temperature, all recarburizer one-time in liquid iron, at the same time with solid charge to press it into the liquid iron.
