As a high-quality abrasive material, the application advantages of white corundum in castables are mainly reflected in the following aspects:
1.White corundum has a melting point of up to 2050 degrees Celsius, so it can still maintain stable properties in high temperature environments and will not break or deform due to high temperatures. This makes the white fused alumina castable suitable for use in high-temperature furnace lining materials that can withstand thermal shock and chemical corrosion at high temperatures.
2.White corundum has good acid and alkali corrosion resistance, and when applied in castables, it can effectively resist the internal erosion of acidic or alkaline media, thereby prolonging the service life.
3.White fused alumina has extremely high hardness and wear resistance, which allows the castables made from it to withstand heavy working conditions, are not easily abrasive, and are suitable for high-wear environments.
4.White corundum has good thermal stability at high temperature and small coefficient of thermal expansion, so when used in castables, it can ensure the stability of the material in the process of thermal cycling and reduce the cracks caused by thermal stress.
5.White corundum has excellent performance in the grinding and polishing process, which can effectively remove impurities such as oxide layer, paint, rust and other impurities on the surface of the workpiece, so that the surface of the workpiece can be restored to smooth and clean. In castables, this property helps to improve the surface finish quality of the material.
6.The amount of dust of white corundum powder is very small, almost does not contain impurities, and it is not easy to produce pollution during use, which meets the requirements of today's industrial production for environmental protection. In castable applications, it is especially suitable for occasions with high environmental requirements.
7.White fused alumina castable is suitable for various types of furnaces, such as cement kilns, high-temperature furnaces in steel plants, reactors in the petrochemical industry, etc., and the ratio and performance of the materials can be adjusted according to different applications and needs.
In summary, the application advantages of white fused alumina in castables lie in its excellent high-temperature performance, corrosion resistance, hardness and wear resistance, thermal stability and environmental protection characteristics, which make white fused alumina castables an ideal choice in high-temperature wear-resistant environments.
