Covering agent for steel ladle and tundish has good spreadability and heat preservation performance, and its remarkable advantage is that it can be automatically crushed and quickly spread on the surface of molten steel after being added into ladle, so as to fully cover molten steel and form a three-layer molten structure from bottom to top, and prevent secondary oxidation and heat radiation of molten steel, in which the liquid layer can absorb inclusions in molten steel and has the function of cleaning molten steel.

Mold flux has good spreading performance, good heat preservation effect, prevention of secondary oxidation and good lubrication performance. It can absorb the inclusions in molten steel without entering the molten steel. It also has good heat transfer control effect, and good effect on different continuous casting machines and different sections.

Silicon carbide has the characteristics of corrosion resistance, high strength and good thermal conductivity. On the one hand, silicon carbide can be used for smelting furnace lining and high-temperature furnace components to improve the service life of lining; On the other hand, silicon carbide can decompose in molten steel and react with oxygen and metal oxides in molten steel to generate carbon monoxide and silicon-containing slag, so it can be used as deoxidizer for smelting steel and composition improver for cast iron.

Deoxidizer is a material used to reduce the content of oxygen and other gases in molten steel. According to the needs of smelting steel varieties, our company has developed a Si-Al-Ba-Ca composite deoxidizer, which is suitable for various deoxidization processes. The product has good deoxidation effect, can reduce harmful gases in molten steel, improve fluidity of molten steel, reduce inclusions and pure molten steel, increase alloy yield and reduce alloy consumption, that is, reduce cost per ton of steel. At the same time, it can replace part of ferrosilicon and calcium silicon, reduce or cancel the wire-feeding process, simplify the steelmaking operation and improve the quality of various steels.
