The Raw Material Of The Carburizer

The main components of the carburizer are carbon content, ash content, volatile matter, moisture, sulfur, nitrogen, hydrogen and other trace elements. The main component of the carburizer is carbon, generally called fixed carbon. Carbon content is the most important indicator to measure the quality of the carburizer. The quality of different carburizers will also be different. Low sulfur and low nitrogen carburizers have a carbon content of more than 98.5%.

The function is to increase carbon, but the quality of different carburizers is also different. For example, there are graphite-based, calcined petroleum coke-based, calcined coal, graphite, scrap electrode fragments, particle recycling, etc. Another is the sulfur and nitrogen content in the composition. The role of sulfur is basically clear to everyone. A certain amount of sulfur in cast iron can better improve the physical properties of castings.
