Silicon Carbide Deoxidizer Application
Both electric furnace steelmaking and coal thermal steelmaking need to add deoxidants to improve the quality of steelmaking and ironmaking. Due to the non-renewable nature of coal resources and the environmental protection of electric power resources, electric furnace steelmaking has been continuously developed. Therefore, the deoxidizers currently on the market generally refer to silicon carbide deoxidizers.
Silicon carbide deoxidizer is a novel high-performance composite deoxidizer, which can replace the more expensive traditional deoxidizer ferrosilicon powder and alloy powder. It is suitable for deoxidation of ordinary steel, alloy steel and special steel during smelting. The advantages of early slag, thick reducing atmosphere, rich foam, etc. can also effectively improve the recovery rate of the elements, and also have the role of carbon replenishment, replacing part of the carbon replenisher, which greatly reduces the cost of steelmaking.
There are many types of deoxidizers commonly used in electric furnace steelmaking. According to the physical state of the deoxidizer, they can be divided into two categories: block deoxidizers and powder deoxidants. Block deoxidants are generally used for precipitation deoxidation, and powdered deoxidants are mainly used for diffusion deoxidation. The use of silicon carbide as a deoxidizing agent for steelmaking can stabilize the quality of molten steel, and has the effect of refining grains and removing harmful impurities in molten steel. After use, the molten steel has a high casting temperature, good slab quality and low unit cost.
Silicon carbide deoxidizer can replace the more expensive traditional deoxidizer ferrosilicon powder and alloy powder. It is suitable for deoxidation during smelting of ordinary steel, alloy steel and special steel. Silicon carbide deoxidizer has rapid deoxidation, early slag formation, strong reducing atmosphere, The advantages of rich foam can also effectively improve the recovery rate of elements, and also have a carbon replenishing effect. Instead of part of the recarburizer, it greatly reduces the cost of steelmaking and improves the production process and product quality of steelmaking.
