Refining Slag（Synthetic Slag) Is A Necessary Metallurgical Auxiliary Material Used in The Refining Process of Molten Steel(LF)

The main components of refined slag（Synthetic slag)  are calcium aluminate, aluminum oxide, silicon oxide, calcium fluoride, magnesium oxide, etc. 

These metal ions combine to form calcium oxide calcium fluoride（CaO-CaF2） based, calcium oxide -aluminum oxide ( CaO- Al₂O₃)based, and calcium oxide aluminum oxide silicon oxide （CaO-Al2O3-SiO2） based composite materials, which are refined slag. Refining slag is a necessary additive for deoxidation and desulfurization in the refining process of steel enterprises.

The forms of refined slag mainly include sintered type, pre melted type, and mixed type.

Xingshi New Material mainly provides ( CaO- Al₂O₃)based synthetic slag,  Premelted  Calcium aluminate slag and Sintered calcium aluminate slag. 

Usage method:

Refining is a necessary process for steel mills to process molten steel, and there are many refining methods, such as slag washing, vacuum, stirring, injection, heating, filtration, etc. The refining of refined slag is slag washing.

Slag washing can obtain clean molten steel and perform deoxidation, desulfurization, and removal of inclusions, making it a relatively simple refining method.

Refining process of refining slag:

Firstly, pour the prepared refining slag into the ladle, and with the help of the impact of the steel flow during steelmaking, the molten steel and refining slag are fully mixed. The metal ions contained in the refining slag will complete the refining tasks of deoxidation, desulfurization, and removal of inclusions in the molten steel. The steel slag mixed out during electric arc furnace smelting, also known as slag washing, is also used in the slag washing garden.

The above is the method and process of refining steel with refined slag. The required refined slag for refining different types of steel is also different, and the required refined slag for different types of steel is also different. Xingshi New Material is a refined slag manufacturer that can provide you with optimized refined slag based on the refined steel you need and the refined effect.
