Refining
Slag is a new auxiliary material of steel making that developed by our
company to meet the requirement of low-sulphur stel. I t was melted
from many kinds of material by electric furnace in high temperature that
makes out the calcium aluminates, which mainly includes 7Al2O3
and 12Cao in more than 90%, and their activity coefficient is more than
70. The product has the following features: quick melted, high activity
degree, quick speed of slag making, early appearing of white slag, high
degree of fluidity after being melted, large quantity of offspring of
deoxidation and desulphurization in molten steel can be absorbed,
refining time can be shortened, and cost of steel making can be
decreased. With all the above features, the harmful impurity in molten
steel can be reduced and the component in molten steel can be purified.
Method of use
1. Added with flow of steel when rapping
2. Or added when position of refining furnace is measured
3. Or added according to technology.
