Use characteristics of graphite carburizer

　　Carburizer used in casting, can greatly increase the amount of scrap, reduce the amount of pig iron or without pig iron. Most of the recarburizer is suitable for electric furnace smelting, there are a small part of the absorption rate of particularly fast recarburizer for cupola. Electric furnace melting feeding mode, should be carburizing agent with scrap and other charges together to put in, small dose can choose to add on the surface of molten iron. But to avoid large quantities of molten iron to feed, in order to prevent too much oxidation and carbon effect is not obvious and casting carbon content is not enough. The addition of carburizer, according to the ratio of other raw materials and carbon content. Different types of cast iron, according to the need to choose different models of carburizing agent. Carburizer features of its own choice of pure carbon containing graphitized material, reduce the excessive impurities in pig iron, carburizer selection can reduce the production cost of casting.
