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 .
