There are many kinds of raw materials for carburizing agent, and the production process is different. There are wood carbon, coal carbon, coke, graphite and so on. There are many small types in various categories.

Characteristics of carburizing agent 
1)The particle size is moderate, the porosity is large, and the absorption speed is fast.
2)Chemical composition is pure, high carbon, low sulfur, harmful ingredients are relatively small, high absorption rate.
3)The product has good crystal structure and improves the nucleation ability of the original molten iron. During inoculation, the number of nodular graphite cast iron is increased, and graphite core is added to the iron melt of the electric furnace, and the distribution of homogeneous graphite in the casting is refined.
4)Excellent performance and stability. Proper carburizing agents can help reduce the cost of smelting and improve the quality of smelting metals and castings.
