The main application scope of alumina refractory

Alumina refractory has good high temperature resistance and alkali corrosion resistance, and also has good oxidation resistance. After making refractory products, the compressive strength is also good. The most important thing is that after making refractory bricks, the refractory temperature can reach 1700 degrees. The above is one of the main members of high temperature refractories.

The varieties of alumina refractory are: advanced refractory brick products, ceramic products, light insulation products, fiber products and amorphous products, etc. The main application scope of alumina refractory are:
1. Furnace lining structural materials for ultra-high temperature furnaces.
2. Crucibles for smelting and purification of high-purity metals, superalloys, rare and precious metals, etc.
3. High temperature furnace tube, thermocouple tube, high temperature insulation, etc.
4. High temperature resistant kiln furniture, gaskets, pressing rods and pressing blocks, etc.
5. High temperature and corrosion resistant furnace lining materials for petrochemical industry.
6. Transparent alumina ceramics can be used as high pressure sodium lamps, microwave covers, high temperature observation window glass.
7.alumina refractory is used in the electronics industry to make circuit substrates, electronic sockets, high-voltage ceramic shells, radomes, spark plugs, etc.
8. Abrasives and abrasives, such as grinding wheel discs, cutting discs, wire drawing dies, drawing tower wheels, textile porcelain parts, sandblasting nozzles, high temperature wear-resistant bearings and various knives, etc.
9. Plunger pump parts for chemical industry, sealing rings, etc.
10. Metallurgical and non-ferrous industry metal melt delivery pipeline.
11. High-temperature, high-efficiency, energy-saving materials for various industrial sectors, such as alumina hollow spheres, alumina whiskers, alumina fibers, etc. and their products.
Alumina refractory has good corrosion resistance to acid, alkali and salt materials. High chemical stability, suitable for use in oxidation, reduction, protective atmosphere and vacuum conditions.
