[0002] Steel slag is a kind of industrial solid waste, which is the slag discharged from steelmaking. It is divided into converter slag, open-hearth slag and electric furnace slag according to the furnace type. It is mainly composed of calcium, iron, silicon, magnesium and a small amount of oxides of aluminum, manganese, phosphorus, etc. The main mineral phases are tricalcium silicate, dicalcium silicate, calcium magnesium olivine, calcium magnesium rhodonite, calcium ferroaluminate and solid solution formed by oxides of silicon, magnesium, iron, manganese and phosphorus. It also contains a small amount of free calcium oxide and metallic iron, fluoroapatite, etc. In some areas, because the ore contains titanium and vanadium, these components are also slightly contained in the steel slag. The content of various components in steel slag varies greatly due to the different steelmaking furnace types, steel types and the smelting stages of each furnace.
