There are many kinds of raw materials for recarburizers, and the production processes are also different. There are woody carbon, coal-based carbon, coke, graphite, etc., among which there are many small types under various categories. High-quality recarburizer generally refers to a recarburizer that has undergone graphitization. Under high temperature conditions, the arrangement of carbon atoms is in the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of impurities in the recarburizer, increase the carbon content of the recarburizer, and reduce the sulfur content. Carbon fiber spun pitch

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. In the feeding method of electric furnace smelting, the recarburizer should be put in with the scrap steel and other charge, and small doses can be added to the surface of the molten iron. However, it is necessary to avoid large batches of materials into the molten iron to prevent excessive oxidation and the occurrence of insignificant recarburization 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, choose different types of recarburizers according to your needs. The characteristics of the recarburizer itself choose pure carbon-containing graphitized substances to reduce excessive impurities in the pig iron, and the appropriate selection of the recarburizer can reduce the production cost of castings.
