There are many kinds of raw materials for carburizing agent, and the production process is also different, including wood carbon, coal, carbon, coke, graphite, etc., among which there are many kinds under small categories. A better carbon agent is often called graphitization by graphitization. At high temperature, carbon atoms are arranged in the micro form of graphite, so it is called graphitization. Graphitization can reduce impurity content in carburizing agent, increase carbon content and reduce sulfur content.
The product is made of high quality taixi smokeless cleaned coal by calcining at 800-1200 ℃ calcining furnace, which is an ideal raw material for steelmaking.
