The carburizer is made by decomposing sulfur and removing nitrogen after calcination. This product has small addition, high efficiency, fast response and fast absorption, which has a good carburizing effect on pig iron and ductile iron. The carburizer is used in casting, which can greatly increase the amount of scrap steel, reduce or eliminate the amount of pig iron. Most carburizers are suitable for electric furnace smelting, and a small number of carburizers with particularly fast absorption speed are used in cupolas. In the feeding method of electric furnace smelting, the recarburizer should be put in together with scrap steel and other furnace materials, and small doses can be added on the surface of molten iron. However, it is necessary to avoid feeding a large amount of materials into the molten iron to prevent excessive oxidation, resulting in insignificant carburization effects and insufficient carbon content in castings. The amount of carburant added is determined according to the ratio and carbon content of other raw materials. For different types of cast iron, choose different types of recarburizers according to your needs. The characteristics of the carburizer itself selects pure carbon-containing graphitized substances to reduce excessive impurities in pig iron, and the appropriate choice of carburizer can reduce the production cost of castings.

Graphitized recarburizer indicators: carbon>98.5%, sulfur<0.05%, ash<0.7%, volatile matter<0.7%, moisture<0.5%, nitrogen<300ppm (different particle sizes can be produced according to customer needs)

Main application scope: casting, steelmaking, wear-resistant materials, etc.
