With the development of the iron and steel industry, steel production is constantly accumulating and increasing, but also with the production of a large number of steel slag. Which includes silicon calcium slag, silicon calcium slag refers to a slag produced in the process of steelmaking because of the addition of a certain amount of calcium oxide and silicon oxide. Silicon calcium slag can be widely used in construction production and smelting, and is also an important steel slag resource.
Formation of silica-calcium slag
In the process of steelmaking, according to different steel types and needs, steel mills usually add a certain amount of calcium oxide and silicon dioxide to the steelmaking furnace, which can react with other substances in the slag to produce silicon calcium slag. The formation of silicon calcium slag can be some changes in important components, for example, after adding calcium oxide and silicon dioxide, the carbon content of hot metal will be reduced, and the calcium-containing substance in the slag can be separated, so that the slag can remove the effective calcium-containing part, and improve the quality and composition of the molten steel.
Properties of silica-calcium slag
The main components of silica-calcium slag are calcium oxide and silicon oxide. Silica-calcium slag has some unique properties
In the process of steel production, the separation of silicon and calcium slag can improve the quality and composition of molten steel, and also make full use of steel slag resources to strengthen sustainable development.
Silicon and calcium slag is an indispensable auxiliary material in steel, ironmaking, metallurgy and other industries, mainly used in steel refining, converter injection, electric furnace smelting and other processes. Silicon calcium slag can play the role of desulfurization, dephosphorization, degassing, reducing slag adhesion, improve the quality of molten steel, and reduce the production cost.
