The role of silicon carbide grinding powder in the steelmaking industry
Silicon carbide grinding powder is an inorganic substance made of quartz sand, petroleum coke and smelted at high temperature in a resistance furnace. What are its applications in the steelmaking industry?
1 The application of silicon carbide grinding powder is summed up after decades of experiments, and it has a better effect in the steelmaking industry. Because it can prevent the precipitation of carbides, increase the amount of ferrite, reduce white Tendency, in addition can improve and improve the mechanical properties.
2. Silicon carbide grinding powder can better increase fluidity, stabilize the composition of molten iron, and prevent segregation in steelmaking enterprises. In addition, it can well reduce the sensitivity of wall thickness, make the structure dense, and cut The surface is smooth and clean, while enhancing the nucleation ability of graphite and increasing the graphite core. Gradually, it is found that silicon carbide can restore rusted waste and alloys, reduce the cost of molten iron, and silicon carbide can be used for better deoxidation. Use to purify molten iron.
3. For most casting products, silicon carbide grinding powder can be well applied. Relatively speaking, it is a better deoxidizer for nodular cast iron, which can reduce the amount of nodularizer added and improve Spheroidization rate, silicon carbide can eliminate the oxidation factor of molten iron, reduce the oxidation of furnace wall, and prolong the life of furnace wall by 30%.
