Graphitizing carburizer used in steelmaking

In order to make up for the carbon content burned in the smelting process of steel and added carbon substances called carburizing agents. The production of qualified carburizing agent must go through strict material selection, and then through high temperature graphitization treatment, in the process of not only sulfur, gas (nitrogen, hydrogen, oxygen >, ash, volatile, moisture and other impurities reduce, its purity will be improved. In the smelting process of iron and steel products, often because of smelting time, holding time, overheating time and other factors, the melting loss of carbon elements in liquid iron increases, resulting in a reduction in the carbon content of liquid iron, resulting in the carbon content of liquid iron can not reach the expected theoretical value of refining.
