Silicon carbide ball deoxidizer is a novel high-performance composite deoxidizer, which can replace the more expensive traditional deoxidizer ferrosilicon powder and alloy powder. It has the advantages of rapid deoxidation, early slag formation, thick reducing atmosphere and rich foam, etc. It can also effectively improve the recovery rate of elements, and also has a carburizing effect, which can replace part of the recarburizer and reduce the cost of steelmaking. Using silicon carbide as a deoxidizer for steelmaking can stabilize the quality of molten steel, refine grains, and remove harmful impurities in molten steel. During the use of traditional silicon carbide, the dust is large, the density is low, and it is not easy to sink. Our company processes the silicon carbide powder into a 30-50mm spherical shape, which has the advantages of high recovery rate, small dust, convenient use and low price.
