Chromium corundum castable is a refractory castable made of chromium ore, corundum (Al2O3) and other refractory aggregates after melting or electric melting. Due to its excellent high temperature resistance, wear resistance, corrosion resistance and other properties, it is widely used in the linings of various high-temperature kilns and smelting equipment. Chrome corundum castable is particularly suitable for environments that require high strength, wear resistance and chemical corrosion resistance.
Kiln linings suitable for chrome corundum refractory castable
1. Cement rotary kiln
Application parts: lining, preheater, cooler, kiln tail and kiln head of cement rotary kiln.
Advantages: Chrome corundum refractories castable has high high temperature resistance and chemical corrosion resistance, can effectively resist the corrosion of high temperature slag and gas in cement kiln, and reduce the wear and damage of kiln lining.
2. Glass kiln
Application parts: melting pool, kiln wall, kiln mouth and regenerator of glass melting furnace
Advantages: Chrome corundum has excellent high temperature resistance and thermal shock resistance, and can withstand the high temperature and chemical corrosion generated during the glass melting process, especially in the long-term use of glass kilns. It has good wear resistance and chemical corrosion resistance.
3. Smelting furnace
Application: linings of smelting furnaces such as converters, arc furnaces, and blast furnaces.
Advantages: Chrome corundum castables can effectively withstand the erosion of molten metal and slag, and provide long-term high temperature stability and erosion resistance. It is particularly suitable for handling high-temperature metals and chemical reaction environments encountered during the smelting process.
4. Aluminum smelting furnace
Application: linings, aluminum melting furnaces, and furnace bottoms of aluminum smelting furnaces.
Advantages: Chromium corundum castables have high temperature resistance and metal molten corrosion resistance, which are particularly suitable for aluminum smelting processes, and can withstand the erosion of molten aluminum, slag, and high-temperature gases.
5. Petrochemical furnace
Application: linings of petrochemical high-temperature furnaces, heating furnaces, catalytic cracking furnaces and other equipment.
Advantages: Chrome corundum castables have strong acid, alkali and chemical corrosion resistance, can effectively resist chemical reactions and high temperature environments generated in the petrochemical process, and extend the service life of equipment.
6. Ladle lining
Application parts: Ladle lining, especially the wall and bottom of the ladle.
Advantages: Chrome corundum refractory castables have very high temperature resistance, strength and resistance to metal molten corrosion, and can effectively protect the ladle from corrosion by molten metal and slag.
7. Ladle and pouring system
Application parts: Ladle lining, pouring device, steel pouring system and other parts.
Advantages: Under the high temperature and chemical corrosion of molten iron and slag, chromium corundum castables can provide reliable protection to ensure the long-term stable operation of equipment.
8. Refractory heating furnace
Application parts: Lining of heating furnace, especially areas that need to resist slag and high-temperature gas corrosion.
Advantages: Chrome corundum castables can effectively improve the high temperature resistance and chemical corrosion resistance of the lining, and are suitable for long-term operation of heating furnaces.
