What is 95 graphite carburizer?

Graphitization recarburizer generally refers to the graphitization of the recarburizer, under high temperature conditions, the arrangement of carbon atoms in the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the recarburizer, improve the carbon content of the recarburizer, reduce the sulfur content. Its use mainly has the following several aspects:

Recarburizer used in casting, can greatly increase the amount of scrap steel, reduce the amount of pig iron or pig iron. At present, the vast majority of recarburizer is suitable for electric furnace smelting, but also a small part of the absorption speed is particularly fast recarburizer for cupola.

The feeding method of electric furnace melting, the recarburizer should be put into the furnace with scrap steel and other charges, and the addition of a small dose can be chosen to be added to the surface of molten iron. But to avoid large quantities of molten iron feeding, in order to prevent excessive oxidation and appear carburizing effect is not obvious and the carbon content of the casting is not enough. The amount of recarburizer added, according to the ratio of other raw materials and carbon content to set, different kinds of cast iron, according to the need to choose different types of recarburizer, recarburizer characteristics of the choice of pure carbon graphitized material, reduce excessive impurities in pig iron, recarburizer selection can reduce the appropriate casting production costs.
