[0002] At present, slag is a by-product of the blast furnace iron-making process. During the iron-making process, iron oxide is reduced to metallic iron at high temperature, and impurities such as silica and alumina in the iron ore react with lime to form a molten material with silicates and aluminosilicates as the main components. After quenching, it becomes a loose, porous granular material, which is blast furnace slag, or slag for short.
[0003] Among them, slag plays an important role in industrial production, especially in some large factories, which use slag to make and refine slag cement, slag powder, slag powder, slag silicate cement, slag wool, blast furnace slag, granulated blast furnace slag powder, copper slag, and slag vertical mill.
