Alumina ceramic liner with hole, mainly composed of high-purity α-alumina (Al₂O₃) through high-temperature sintering, typically has an alumina content higher than 92%. This type of liner has a flat plate structure, with a through-hole on the surface. The hole diameter and spacing can be designed according to application requirements. Its performance characteristics include high hardness, excellent wear resistance, good chemical corrosion resistance, and outstanding high-temperature resistance, with a working temperature of up to 1600 degrees Celsius. Moreover, its structural design takes into account both lightweight and mechanical strength, making it convenient for installation and maintenance.
In the industrial field, alumina ceramic liner with hole is widely used in material conveying systems, equipment protection, and ventilation and dust removal devices. For instance, in industries such as thermal power generation, cement production, and steel smelting, they are employed as internal liners for equipment like silos, chutes, and cyclone separators, effectively resisting material erosion and wear. The design of its pore structure offers both functional advantages, reducing overall weight while allowing air flow through or material screening, and providing installation positions for fixed bolts, thereby enhancing system integration efficiency.
In conclusion, the alumina ceramic liner with hole is a high-performance industrial material that integrates wear resistance, protection, and structural functions. Through the combination of material properties and geometric design, it significantly extends the service life of equipment, reduces maintenance costs, and demonstrates significant application value in harsh industrial environments. In the future, with further optimization of manufacturing processes, its application scope is expected to continue to expand.
