Calcium Aluminate(Premelted Calcium Aluminate Residue)

Calcium Aluminate

Calcium aluminate(Premelted calcium aluminate residue)

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 . Its applications have  already been mature in some foreign countries , such as South Korea , Japan , the United States and the developed European countries.

characterized:

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 .

Usage:

1.If deoxidation is the main process , you shall add it to the capsule bottom directly before tapping .The amount of adding depends on the carbon content in the molten steel , and is generally allocated with steel of 4-6kg/1000kg .

One quarter before tapping , you shall add ferromanganese , ferrosilicon and aluminum with the general amount .

After tapping , you shall add manganese ,ferrosilicon with general amount to the carbon steel , without adding any other alloys and aluminum feed line , and the steel ladle only needs to be refined by Argon blowing process .

If you use the product to deoxidize , the increasing carbon agent(SiC) can be reduced by 30-50% in volume .

2.If desulfurization is the main process , you shall add it to the capsule bottom with one-third of usage , but it must be at the capsule bottom of the steel pounding .

With the outflow of molten steel , you shall add two-thirds of it .

And the steel usage of 6-8kg/1000kug is depends on the original sulfur content in steel and the using results .
