Product Introduction
Carburizer: used in casting, can greatly increase the amount of scrap steel, reduce the amount of pig iron or do not use pig iron. In the feeding method of electric furnace melting, the carburizer should be put into the furnace together with the furnace charge such as scrap steel, and the addition of small doses can be selected to add on the surface of hot metal. However, it is necessary to avoid putting material into the hot metal in large quantities to prevent excessive oxidation and the carburization effect is not obvious and the carbon content of the casting is not enough. The amount of carburizer added is determined according to the ratio and carbon content of other raw materials. Different types of cast iron, according to the need to choose different types of carburizer. The additives themselves choose pure carbon-containing graphitized substances, reduce excessive impurities in pig iron, carburizing agent selection can reduce the production cost of casting.
