As a high-performance inorganic non-metallic material, has excellent high temperature resistance, wear resistance and corrosion resistance, so it has been widely used in metallurgy, electric power, chemical industry and other fields. However, the service life of ultra-low cement iron trench castables has always been a bottleneck restricting its further development. Therefore, how to improve the service life of ultra-low cement iron trench castables is very important.
Research on the service life of refractory low cement castables mainly includes research on material composition, preparation technology and use environment. First, by optimizing the material composition, reducing the cement content, and improving the material's compactness and impermeability, its service life is improved. Secondly, the preparation process is improved and advanced molding technology and high-temperature sintering technology are used to make the material more uniform and dense, and improve its mechanical properties and thermal stability. Finally, according to different use environments, carry out targeted research to improve the wear resistance, corrosion resistance and thermal shock resistance of materials.
The industrial application of low cement castables mainly includes smelting furnace troughs, hot blast furnace troughs, tap troughs, ladles and other high-temperature, wear-resistant and corrosion-resistant occasions. In these situations, It can effectively resist high temperature, wear and corrosion, ensuring long-term stable operation of equipment. At the same time, due to its excellent performance, low cement refractory castables can also replace traditional refractory materials, reducing energy consumption and environmental pollution.
In short, the longevity research and industrial application of ultra-low cement castables play an important role in improving the performance of the material and promoting the development of related industries. In the future, with the continuous advancement of science and technology, the application fields of ultra-low cement iron trench castables will be more extensive, and its performance will be further improved.
