Product Description

The anthracite  recarburizer  produced  by  our company  chose the  high-quality  Taixi coal  in  Ningxia  as  the  raw material,through a series of processes such as crushing,washing and calcining.It has the characteristics of high carbon content,stable quality and high-performance ratio.It is a high-quality auxiliary material for steelmaking and foundry.

Ningxia calcined anthracite recarburizer, there are many kinds of raw materials for recarburizer, and the production processes are also different, including wood carbon, coal carbon, coke, graphite, etc., among which there are many small categories under various categories. Recarburizer generally refers to a graphitized recarburizer. 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. The recarburizer is used in casting to greatly increase the amount of scrap steel, reduce the amount of pig iron or not use pig iron. In the feeding method of electric furnace smelting, the recarburizer should be put in together with scrap steel and other furnace materials, and a small dose can be added to the surface of the molten iron. However, it is necessary to avoid feeding large quantities of materials into the molten iron to prevent excessive oxidation and the situation where the recarburization effect is not obvious and the carbon content of the casting is insufficient. The amount of recarburizer added is determined according to the ratio and carbon content of other raw materials. Different types of cast iron require different types of recarburizers. The recarburizer features pure carbon-containing graphitized substances to reduce excessive impurities in pig iron. Choosing the right recarburizer can reduce the production cost of castings.
