    High quality carburizing agent generally refers to the carburizing agent after graphitization. Under high temperature conditions, the arrangement of carbon atoms is the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in carburizing agent, improve the carbon content of carburizing agent, reduce the sulfur content.

 

    Carburizing agent used in casting, can greatly increase the amount of scrap, reduce the amount of pig iron or do not use pig iron. The feeding method of electric furnace smelting, should be carburizing agent with scrap and other charge together to put in, small dose of addition can choose to add on the surface of hot metal. But to avoid large quantities to the molten iron feeding, in order to prevent excessive oxidation and carburizing effect is not obvious and the carbon content of the casting is not enough. The addition of carburizing agent, according to the ratio of other raw materials and carbon content to determine. Different kinds of cast iron, according to the need to choose different models of carburizing agent. Carburizing agent characteristics itself choose pure carbon graphitized material, reduce excessive impurities in pig iron, carburizing agent selection can reduce the production cost of casting.

Applications
 

    For casting, cast iron, cast steel, castings will have a requirement for carbon, then carburizing agent as the name suggests is to increase the carbon content in liquid iron, and for example, in smelting commonly used furnace for pig iron, scrap, return charge, pig iron carbon content is high, but the purchase price is higher than scrap, so increase the amount of scrap, reduce the amount of pig iron, Adding carburizer can play a certain role in reducing casting cost.

    High carbon and low sulfur carburizing agent for gray cast iron casting. Graphite carburizer is suitable for ductile iron with strict requirements on sulfur, high fixed carbon content and good absorption rate, especially suitable for medium frequency furnace of 0.5 tons to 12 tons.
