Calcium aluminate

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.

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. Tested by the users, the stability of our 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.
