Alumina lining is calcined from alumina or zirconia at high temperature. Alumina is transformed into dense alpha alumina under high temperature environment. Due to the special crystal structure, it becomes extremely hard, and its hardness is second only to diamond. Wear resistance is several times or even more than other wear-resistant materials.

Alumina Lining Details
Alumina ceramic lining is a wear-resistant material commonly used in high temperature environments. It is made of high-purity alumina powder and processed through molding and sintering processes. Its wear resistance and impact resistance benefit from its high hardness, fine grain structure, high bonding force, high density and compactness, and good chemical stability. These properties make alumina ceramic linings an ideal material for a variety of applications requiring protection against wear and impact.
1.High temperature resistance: Alumina lining has excellent high temperature resistance, and can be used for a long time in a high temperature environment without failure.
2. Good wear resistance: It has excellent wear resistance and can resist abrasion and impact of materials.
3. High insulation performance: It has good insulation performance and can effectively isolate the conduction of current and heat.
Alumina ceramic linings are widely used in many fields due to their excellent performance. Here are some major application scenarios:
1. Mining and metallurgical industry: alumina linings are widely used in mining equipment and metallurgical industry. It can be used as the lining of grinding machines, ball mills, jaw crushers and other equipment to provide protection against wear and impact and prolong the service life of the equipment.
2. Chemical industry: Due to its excellent chemical stability, it is widely used in equipment and pipeline linings in the chemical industry. It can resist the erosion of corrosive media such as acid, alkali, solvent, etc., and protect the equipment from being damaged by corrosion.
3. Power industry: In power plants and power equipment, it is often used as insulating and protective materials. It has excellent insulation performance and high temperature resistance, and can be used in insulating parts, electrical partitions, porcelain bushings and other components to ensure the safe and reliable operation of electrical equipment.
4. Iron and steel industry: In the iron and steel industry, high alumina linings are widely used in smelting equipment and casting equipment. It can be used as the lining and protective material of high-temperature furnaces, which can withstand high temperature and wear, and prevent corrosion and erosion of equipment by liquid metal.
Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
