Refining slag
Introduce
Refining slag refers to the technology of mixing raw materials in a certain proportion and particle size, heating them below the melting point of the raw materials, sintering them together, and then crushing them into particle sizes for use. The main components of refining slag are CaO-CaF2 based, CaO-Al2O3 based, and CaO-Al2O3-SiO2 based. The main forms of refining slag include sintered refining slag, pre melted refining slag, and mixed refining slag. Refined slag is a necessary additive for deoxidation and desulfurization in the refining process of steel enterprises. It is an indispensable auxiliary material. Composite refining slag balls, formulated through high-tech technology, are more suitable for the purification of high-grade steel.
Application
The main components of refining slag are calcium aluminate, aluminum oxide, silicon oxide, calcium fluoride, magnesium oxide, etc. These metal ions combine to form a composite material of calcium oxide calcium fluoride base, calcium oxide aluminum oxide base, and calcium oxide aluminum oxide silicon oxide base, which is called refining slag. Refined slag is a necessary additive for deoxidation and desulfurization in the refining process of steel enterprises. Refined slag can be used as a flux and desulfurizer in steel smelting, which can reduce the viscosity of slag and improve steelmaking efficiency. Refined slag can also be used for soil improvement and agricultural production, which can improve soil fertility and crop yield.
Characteristic
The refined slag produced by Weida Company has advantages such as uniform chemical composition, low melting point, fast melting speed, reduced refining power consumption, and shortened refining time. It is increasingly valued by steel enterprises and is currently one of the important steelmaking additives.
Refining slag has greatly improved the efficiency of steel production, as well as the quality and performance of finished steel products, by replacing the production process that relied on high alkali materials, slag steel mixing, and external desulfurization in current steelmaking enterprises.
