Introduction to Carburizer
A carburizer is a crucial additive in the steel – making and foundry industries. It is used to increase the carbon content in molten metal, which helps to improve the mechanical properties of the final metal products, such as hardness, strength, and wear – resistance. Carburizers come in different types, including natural graphite, artificial graphite, and calcined petroleum coke. The choice of carburizer depends on various factors like the type of metal being processed, the desired carbon content, and the specific requirements of the production process. Carburizer
