Steel-making Desulfurizer
Product introduction
The main components of refining slag are calcium aluminate, alumina, silicon oxide, calcium fluoride, magnesium oxide, etc. These metal ions are combined into calcium oxide-calcium fluoride base, calcium oxide-alumina base, calcium oxide-alumina- Silicon oxide base; The formed composite material is the refining slag. Refining slag is a necessary additive for deoxidation and desulfurization in the refining process of iron and steel enterprises.

Application
Put the refining slag into the ladle before tapping, because the molten steel flows into the ladle from the upper layer, the molten steel and the refining slag are vigorously stirred, and the refining slag is quickly melted into the molten steel, and then aggregates and floats. Because of the strong reducibility of the refining slag, it has a strong deoxidation and desulfurization ability, which can remove oxygen and sulfur impurities in the molten steel during the mixing process of molten steel. At present, the desulfurization capacity of refined slag can reach more than 85%, which is a very good steelmaking additive.
