High alumina brick is a high-temperature refractory material, which is mainly made of high-purity bauxite through smelting, shaping, drying, and sintering processes. It has good high-temperature, acid, alkali corrosion, and wear resistance. High alumina bricks are widely used in high-temperature equipment such as furnaces, kilns, converters, electric furnaces, and heat treatment furnaces to meet the requirements for use under high-temperature conditions. This article will detail the manufacturing process, performance characteristics, application fields, and other related content of high alumina bricks.
High alumina bricks are mainly made from high-purity bauxite through crushing, mixing, shaping, drying, and sintering processes. Its alumina content is above 48%. During the manufacturing process, the sintering temperature of high-alumina bricks can be as high as over 1750°C, allowing them to remain stable in high-temperature environments.
1. High-temperature resistance: The high aluminum content and dense structure of high alumina bricks give them excellent high-temperature resistance and can be used for a long time in high-temperature environments without melting, softening, or expansion.
2. Acid and alkali corrosion resistance: High alumina bricks contain a large amount of aluminum oxide, which gives them good acid and alkali corrosion resistance.
3. Anti-wear performance: High-aluminum bricks have high surface hardness and are not easy to wear and break.
4. Good thermal conductivity: High alumina bricks have low and excellent thermal conductivity.
High alumina bricks are widely used in high-temperature equipment such as furnaces, kilns, converters, electric furnaces, and heat treatment furnaces to meet the requirements for use under high-temperature conditions. In steel, metallurgy, chemical industry, ceramics, and other industrial fields, high alumina bricks are an indispensable high-temperature refractory material. They can exert good high-temperature, acid, alkali corrosion, and wear resistance in high-temperature environments.
