This product is an agent for deoxidizer and slagging. It can improve the fluidity of the melten slag produced in refining process, make Al2O3 seperation easier, prevent the defuse of the impurities in the molten slag to guarantee producing high quality steel. It can be used to replace the expensive metal aluminum as the deoxidizer and reduce cost of production.
