Refractory materials for steel mainly include corundum refractory materials, silica refractory materials, aluminum refractory materials, calcium refractory materials, magnesium refractory materials, carbon composite refractory materials and special refractory materials. These materials are widely used in various links of steel production, including blast furnaces, converters, electric furnaces and other equipment, and are essential to ensure the quality and efficiency of steel production.
1. Corundum refractory materials: With Al₂O₃ as the main component, it has excellent properties such as high strength, high temperature resistance, oxidation resistance, electrical insulation, and good air tightness. It is widely used in high temperature areas of steel production, such as furnace linings and furnace roofs.
2. Silica refractory materials: With SiO₂ as the main component, it has good resistance to acidic slag erosion, but is easily eroded by alkaline slag. It is mainly used in thermal equipment such as coke ovens, glass melting furnaces, and acidic steelmaking furnaces.
3. Aluminum refractory materials: including clay and high-aluminum materials, with good thermal vibration resistance and corrosion resistance to acidic slag, suitable for various high-temperature industrial furnaces.
4. Calcium refractory materials: with CaO as the main component, with good resistance to alkaline slag, suitable for alkaline steelmaking furnaces and cement kilns, etc.
5. Magnesium refractory materials: with MgO as the main component, with high refractoriness and strong resistance to alkaline slag, widely used in high-temperature areas in steel production.
6. Carbon composite refractory materials: combining the high-temperature strength of carbon materials and the stability of refractory materials, suitable for high-temperature and highly corrosive environments.
7. Special refractory materials: including various new inorganic non-metallic materials, such as nitrides, carbides, etc., suitable for special high-temperature industrial environments.
The application of these refractories in steel production not only ensures the smooth progress of the production process, but also improves production efficiency and product quality, which is of great significance to the development of the steel industry.
