For casting, cast iron, cast steel, cast carbon will be a requirement, so recarburiser name suggests is to increase the carbon content in liquid iron, and for example, the charge is often used in the smelting of pig iron, scrap, scrap, high carbon content of pig iron, but the purchase price is relatively higher scrap section, put the amount of scrap is increased, reducing the amount of iron put in, plus carbon agent, can play a role to reduce the casting cost.

Product characteristics and application scope: high content of fixed carbon, low sulfur content, stable carburetion effect and high absorptivity of carbon, best degree of graphitization, improve the nucleation of melted iron, it is mainly applied to the carburetion of various electrode smelting cast steel and iron casting.
