Carbon additive is a product that is added to molten steel. Carbon additive includes calcined petroleum coke, graphite petroleum coke, calcined anthracite coal, electrical calcined anthracite, and natural graphite.
Carbon additive is mainly used in steel mills, its main use is to increase the loss of carbon in the process of steelmaking, in the process of steelmaking if the carbon content does not meet the expected requirements, it is necessary to put a certain proportion of carburizing agent, which is mainly in order to improve the carbon content of molten steel, thus smelting the ideal steel.
Carbon additive can also be used in casting industry, which can reduce costs, and has lubrication purposes. It can effectively improve the service life of castings, and improve the quality of the castings.
