Silicon Carbide

Silicon carbide is smelted at high temperature in a resistance furnace from raw materials such as silica, anthracite (or low-sulfur petroleum coke), and wood chips (salt is required when producing green silicon carbide).

Product Advantages

• Composite deoxidation. Compared with single element deoxidizer, its deoxidizing element has a stronger effect.
• Reduce costs. Compared with alloys such as ferrosilicon and aluminum powder, the cost is lower. Adding silicon carbide in the early stage of tapping in the converter has the advantages of easy operation and saving equipment investment compared to the new technology of carbon powder deoxidation during tapping.
• It has few impurities and is relatively pure, which is crucial for smelting high-quality steel such as cord steel.
• Silicon carbide causes the deoxidation product CO to overflow from the molten steel or top slag, thereby blowing argon or foaming the top slag to enhance the refining effect.
• It has good heating effect, which is beneficial to reducing the converter tapping temperature and improving the steel quality.
