Applications

Steelmaking Deoxidation: Used in the production of ordinary carbon steel, alloy steel, and special steel. It reduces the oxygen content of molten steel, decreases oxide inclusions, and improves the cleanliness of molten steel and the quality of finished steel.

Steelmaking Carburization: As a highly efficient carburizing material, it improves carbon absorption efficiency, helps to quickly adjust the composition of molten steel, and reduces the amount of traditional carburizing agents used.

Cast Iron Production: Suitable for the production of gray cast iron and ductile iron. It promotes graphitization, improves the uniformity of microstructure, and enhances the strength and machinability of castings.

Furnace Charge Optimization: It can partially replace ferrosilicon and carburizing agents, reducing the types of alloys, optimizing the batching structure, and lowering inventory and procurement costs.

Applicable Industries: Widely used in steel mills, foundries, alloy material production enterprises, and various metallurgical processing enterprises.
