Applicable Scenarios
Iron and Steel Smelting Industry: Primarily used in the deoxidation, carburization, and desulfurization processes of steel smelting. It can replace traditional deoxidizers and is suitable for the production of plain carbon steel, alloy steel, and special steel. It is especially suitable for the melting process of steel scrap, providing efficient deoxidation and serving as a heating agent and recarburizing agent to improve the strength, toughness, and wear resistance of steel.
Foundry Industry: As a core additive in cast iron production, it effectively provides two key elements, carbon and silicon, promoting the precipitation of carbon in the form of free graphite. This improves the machinability and vibration resistance of cast iron, reduces defects such as porosity and cracks in castings, and enhances casting quality. It is suitable for the production of complex castings such as automotive engine blocks, machine tool bases, agricultural machinery parts, and pipe valves.
Other Fields: It can be used for deoxidation treatment in the aluminum processing industry and as an auxiliary raw material in emerging fields such as new energy equipment and 3D printing metal powders. With the development of industrial technology, its application scenarios are constantly expanding.
