Refining slag production process

The production process of pre-melted refined slag and the production process of sintered refined slag are completely two different production methods, both in terms of process and chemical composition. There are great differences.Pre-melted refining slag is the electrolysis of various components, and the reaction of various components, both in terms of chemical composition and in terms of organizational structure, there are great changes.Sintered refining slag is formed by the combination of various ingredients and calcined at high temperature.

Refined slag does not contain impurities such as fluorine, hydrogen, nitrogen, carbon, etc., which is conducive to improving the quality of steel produced; it does not absorb water and will not corrode the lining and ladle; the structure is dense and easy to transport and store; the product itself has a stable physical phase, fast slag formation, and significantly reduces dust pollution in steel mills.The widespread use of refining slag has led steelmaking companies to change the production process of relying on high-alkali materials for refining, mixing slag steel, and desulfurization outside the furnace, which has greatly improved the efficiency of steel production and improved the quality and performance of finished steel products.
