How to deal with blast furnace slag

10 Aug,2022 UTC+8 Views:


Blast furnace slag is a by-product of the ironmaking process. In the process of iron making, iron oxide is reduced to metallic iron, and impurities such as silica and alumina in iron ore react with lime to form a melt with silicate and aluminosilicate as the main components, which are then quenched to form a molten metal. The loose and porous granular material is blast furnace slag. The chemical composition of slag is CaO, SiO₂, Al₂O₃, MgO, MnO, Fe₂O₃ and other oxides and a small amount of sulfides such as CaS, MnS, etc.
In industrial production, slag plays an important role, especially in some major factories. Slag can be refined and processed into slag cement, slag micro powder, slag Portland cement, etc. So what kind of equipment can effectively process blast furnace slag?
