Carburizer according to casting use and material can be divided into what catego

　　Carburizing agent as a commonly used material in cast iron process, mainly divided into two categories, one is graphitized carburizing agent, and a non-graphitized carburizing agent, these two categories belong to carburizing agent! Is the difference between the two the difference in graphite? Graphitization carburizer: spent graphite electrode, graphite electrode scraps and debris, natural graphite granulation, graphitization coke and silicon carbide. Non graphitized carburizer: bitumen coke, calcined petroleum coke, acetylene coke and calcined anthracite.

　　Carburizer according to the casting use, material and use method can be specifically divided into the following:

　　1. According to casting purposes

　　A. Nodular iron carburizer :C> 98.5s <0.05 mainly graphitized petroleum coke and graphitized electrode. High absorption rate, fast absorption time.

　　B. Gray iron carburizer :C>90 S<0.5 Mainly non-graphitized petroleum coke and calcined coal. The absorption rate is about 85 percent.

　　C. Carburizing agent for steelmaking :C 75-98 mainly calcined coal, graphite ball and natural graphite crushed.

　　D. Special carburizer: used for brake pads and core-wrapped wires. Generally 0-0.5/0.5-1 mm petroleum coke.

　　2. According to the material

　　A. metallurgical coke carburizer: cupola with large coke.

　　B. Carburizing agent for calcined coal: mostly produced in Ningxia and Inner Mongolia C 90-93 S 0.3-0.5 (used for steelmaking and gray iron).

　　C. Petroleum coke carburizer: mostly produced in Liaoning, Tianjin and Shandong C 96-99 S 0.3-0.7 (used for steelmaking, gray iron and special carburizer).

　　D. graphitized petroleum coke: mostly produced in Shandong and Henan, and C 98-99.5s 0.03-0.05 including graphitized petroleum coke and graphitized electrode (for ductile iron).

　　E. Natural graphite carburizer: mainly produced in Hubei and Shandong, C 65-99 (used for steelmaking).

　　F. Carburizer for composite materials: C 93-97s 0.09-0.7 is artificially manufactured from graphite powder, coke powder and petroleum coke.

　　Carburizer can be classified according to the casting process, can also be classified according to the material, according to the material of the carburizer, we also introduced to you the origin of different carburizer is specific where! Synthetic cast iron technology can not only improve the quality of castings. Can also save production costs, the use of carburizer is very necessary oh!
