Refined slag of calcium silicate

[Product Specifications]: 3-40mm \ 5-30mm \ 200mesh-0

[Production capacity]: 20,000 tons

[Scope of application]: good spreadability, can quickly spread on the surface of molten steel to achieve full coverage of molten steel; can prevent secondary oxidation and thermal radiation of molten steel, and absorb non-metallic inclusions such as Al2O3;

【product description】:

Calcium silicate refining slag is synthesized by using high-quality silica (SiO2 ≥ 98%) and high-quality limestone (CaCO3 ≥ 97%) as raw materials, clean electricity as energy, and SiO2 + CaCO3 → CaSiO3 + CO2 ↑ reaction melting synthesis at high temperature. Pre-melted composite calcium silicate series products are synthetic products with more stable chemical composition and uniform phase structure than natural wollastonite.

After the molten material is quenched with water, a cryptocrystalline vitreous body is formed, and the final product has good spreadability, with few impurities. The loss on ignition is almost zero, which is an ideal base material for metallurgical continuous casting protection slag, and is also an ideal raw material for electrode coating.

Application range

After the molten material is quenched with water, a cryptocrystalline vitreous body is formed, and the final product has good spreadability, with few impurities. The loss on ignition is almost zero, which is an ideal base material for metallurgical continuous casting protection slag, and is also an ideal raw material for electrode coating.

Production Process

High-quality quartz sand, bauxite, and lime are smelted in an electric furnace in a certain proportion. Adjust the proportion according to customer needs.
