Fused calcium aluminate (Premelted calcium aluminates residue) is mainly used for separating the impurity elements such as sulfur and oxygen in ladle refining of LF furnace, open hearth furnace and the converter furnace, and it can reduce the content of harmful elements and impurities, which is applicable for general carbon steel, high carbon steel, high and low alloy steel. Its applications have already been mature in some foreign countries, such as South Korea, Japan, the United States and the developed European countries.
Over the years, Ruishi Company has been engaged in the research and development of fused calcium aluminate. In recent years, based on technical support of Luoyang Institute of Refractories, referring to various formulations of different manufacturers at home and abroad, and adopting a variety of comments and suggestions of the users, Ruishi Company has made impressive performances in the whole production process from smelting, manufacturing to using of the fused calcium aluminate. Fused calcium aluminate of our company takes the advantages of uniform chemical compositions, low melting point, high melting speed, and short smelting time. And it has no fluoride and doesn¡¯t erode furnace lining and ladle, and it is compact, non-absorbent, and easy to storage as well. As fused calcium aluminate has stable phase and fast dust-reducing speed, we can reduce the pollution of steel mill and make the refining technique mature. Without other impurities such as hydrogen, nitrogen, carbon, it can help to improve the quality of steel. Tested by the users, the stability of our fused calcium aluminate products is long-tested, and it avoids many instable phenomena brought by the middle and lower end products such as sintering materials, and cupola furnace products.
In addition, we can organize mass production according to the different chemical composition requirements of the customers and keep confidential for them.
