Types And Ingredients Of Carburant

The main component of the recarburizer is carbon, but the existence of carbon in the recarburizer may be amorphous or crystalline. Research and application show that, with the same amount of carbon increase, the carbon increase rate of crystalline recarburizer is faster than that of amorphous recarburizer. The raw iron without spheroidizing treatment has a small white mouth depth, a high ferrite content in the ductile iron matrix, a large number of graphite nodules, and a rounded graphite shape. According to the existence of carbon in the recarburizer, it is divided into graphite recarburizer and non-graphite recarburizer.

Graphite recarburizers include waste graphite electrodes, graphite electrode scraps and scraps, natural graphite pellets, graphitized coke, etc. In addition, silicon carbide has a hexagonal structure similar to graphite, and is also listed as a special form of graphite recarburizer. Non-graphite recarburizers such as pitch coke, calcined petroleum coke, acetylene coke pellets, calcined anthracite recarburizers, etc.
