The important role of recarburizer in casting

What role does the recarburizer play in the casting process? Come into our classroom today, walk into the world of recarburizer, and explore what role this tiny object plays! As we all know, recarburizers are used in casting, which can greatly increase the amount of scrap steel, reduce the amount or use 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 in 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 is to select pure carbon-containing graphitized substances to reduce excessive impurities in the pig iron. The appropriate selection of the recarburizer can reduce the production cost of castings.
