CaSi Alloy

CaSi Alloy is an ideal composite deoxidizer and desulfurizer. The silicon alloy not only has strong deoxidizing ability, with deoxidation products easily flotating and being removed, but it also improves the properties of steel, enhancing its plasticity, impact toughness, and fluidity. In addition, calcium-silicon alloy is suitable as a heating agent in converter steelmaking workshops, and can also be used as an inoculant for cast iron and an additive in ductile iron production.

Steelmaking and Metallurgical Industry: CaSi Alloy is suitable for the production of various steels, including carbon steel, low-carbon steel, stainless steel, and special alloy steel. Used as a composite deoxidizer, desulfurizer, and molten steel purifier, it effectively improves the purity, density, and mechanical properties of steel, perfectly adapting to mainstream smelting furnace types such as converters, electric furnaces, and LF refining furnaces.

Cast iron casting industry: Used as a special inoculant for gray cast iron and ductile iron, it can refine graphite structure, uniformly distribute graphite, reduce the tendency of white iron in castings, improve casting strength, wear resistance, and surface finish, and improve the overall quality of castings.

Other metallurgical applications: Can be used as an auxiliary heating agent in steelmaking and an additive in non-ferrous metal smelting, assisting in melt purification and precise composition control, meeting the stringent production requirements of high-end metallurgy and fine smelting.

Q1: In which metallurgical processes is CaSi Alloy mainly used?

A1: Primarily used in the deoxidation and desulfurization stage of steelmaking refining, molten steel purification, and in the inoculation and modification stage of cast iron production. It can also be used as an additive in non-ferrous metal smelting and a heating auxiliary material in steelmaking, suitable for various mainstream metallurgical furnace types such as electric furnaces, converters, and LF refining furnaces.

Q2: How to select the appropriate CaSi Alloy grade?

A2: For conventional steelmaking deoxidation and desulfurization scenarios, standard grades CaSi 5528 and CaSi 6030 are sufficient. For high-end special steel and ductile iron production scenarios requiring refined processes, customized silicon-calcium ratios and particle size specifications can be determined based on impurity control standards and feeding methods.

Q3: Are there any requirements for the feeding method and dosage of silicon-calcium alloy?

A3: Block products are suitable for direct feeding into the furnace, granular products are suitable for fine feeding using wire feeders, and powdered products are mostly used in special refining processes. Specific dosage needs to be calculated based on the steel/iron volume and initial impurity content. We can provide free technical guidance.
