2.Uses of graphitized recarburizer:

The recarburizer is used in casting, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or eliminate the need for pig iron. At present, most of the recarburizers are suitable for electric furnace smelting, and a small part of the recarburizers with a particularly fast absorption rate is used in cupolas.

In the feeding method of electric furnace smelting, the recarburizer should be put in with the scrap steel and another charge, and small doses can be added to the surface of the molten iron. However, it is necessary to avoid large batches of materials in the molten iron to prevent excessive oxidation and the occurrence of insignificant decarburization effects and insufficient carbon content of the castings. The amount of recarburizer added is determined according to the ratio of other raw materials and the carbon content. For different types of cast iron, different types of recarburizers can be selected according to the needs. The characteristics of the recarburizer itself select pure carbon-containing graphitized substances to reduce There are too many impurities in pig iron, and the proper selection of recarburizer can reduce the production cost of castings.
