Description of  Carburizing Agent:

In the smelting process of iron and steel products, due to factors such as smelting time, holding time, and overheating time, the smelting loss of carbon in the molten iron increases. As a result, the carbon content in the molten iron is reduced, and the carbon content in the molten iron does not reach the theoretical value expected in refining. In order to make up for the carbon content burned during the iron and steel smelting process, the added carbon-containing substances are called Carbon Raiser. We can supply carburizing agent for steelmaking and graphitization carburizing agent.
