Introduction to Carburizer
A carburizer is a crucial additive in the metallurgical industry, especially in steel and iron production. Its main function is to increase the carbon content in molten metal, thereby improving the mechanical properties of the final metal products, such as hardness, strength, and wear - resistance. Carburizers can be classified into different types, including natural graphite carburizers, artificial graphite carburizers, and calcined petroleum coke carburizers, each with its own unique characteristics and application scenarios. The quality of a carburizer directly affects the quality of the metal products, so choosing a reliable carburizer factory is of great significance for metallurgical enterprises.
