Specifications

Uniform chemical compositions , low melting point , high melting speed , and short smelting time

It’s mainly used for separating the impurity elements such as sulfur and oxygen in lable refining of LF furnace , open hearth furnace and the converter , 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 . 

 

Uniform chemical compositions , low melting point , high melting speed , and short smelting time .

It has no fluoride and doesn’t erode furnace lining and ladle .

It’s 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 .
