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 is essential for achieving the desired mechanical properties of the final metal products. By adjusting the carbon level, carburizers can enhance the hardness, strength, and wear - resistance of steel and cast iron. Different types of carburizers, such as graphite - based, coal - based, and petroleum - based carburizers, are available in the market, each with its own characteristics and applications.
