Products Description
Refractory high alumina bricks is a common refractory material whose main components are high-purity alumina and alumina-aluminum silicate composite materials. It can be used continuously above 1500°C, so it has been widely used in various high-temperature equipment. High alumina bricks are resistant to high temperatures, corrosion, and wear, and are widely used in high-temperature process equipment and masonry construction in industries such as electric power, steel, papermaking, cement, and glass.

Products Advantages
1. Good heat resistance. Refractory high alumina bricks will not melt or deform in high temperature environments, and can withstand varying degrees of rapid cooling and thermal shocks.
2. Good wear resistance. High alumina bricks have higher wear resistance than other refractory materials and can withstand the erosion and friction of high-speed flowing materials.
3. Good acid and alkali corrosion resistance. High alumina bricks have good corrosion resistance and chemical stability in acid and alkali media.
4. Long service life. Because high alumina bricks have good resistance to high temperatures, wear and corrosion, their service life is longer than other materials.
Products Applications
1. Metallurgical industry
Refractory high alumina bricks have high thermal conductivity and high temperature resistance, and can be used in high-temperature equipment linings, slag mouths, ladles, converters, electric furnaces, etc. in the metallurgical industry. It will not peel or deform under high temperatures and can meet the requirements of the production process.
2. Construction field
Due to its fire-resistant properties, high-alumina bricks can also be used as fire-resistant structures for interior and exterior walls and partition materials in the construction field. In construction sites, safety issues are more important. The use of high alumina bricks can improve the fire resistance of buildings and ensure the safety of personnel.
3. Petroleum, chemical and energy fields
High alumina bricks have good corrosion resistance and can be used as lining materials for liquid storage containers, powder transportation pipelines, reactors, storage tanks, etc. in the fields of petroleum, chemical industry, and energy.
4. Glass kiln, cement kiln, ash kiln, heat treatment furnace, etc.
High-alumina bricks are used as lining materials in high-temperature equipment in these industries. It does not deform, peel or smoke under high temperatures, and will not cause defects when used for a long time.
