Product introduction of anti-stripping high alumina brick
High Anti-stripping alumina brick are made of raw materials that are inconsistent with the expansion coefficient of high-alumina bauxite. The thermal shock stability of the product enhances the high temperature and chemical corrosion resistance. The service life of Anti-stripping high alumina brick is more than 3 times that of traditional high-alumina bricks.
Application of high Anti-stripping alumina brick
high Anti-stripping alumina bricks are mainly used in the transition zone of cement rotary kiln, decomposition furnace, tertiary air duct, and other thermal equipment requiring thermal shock.

Production process of high Anti-stripping alumina brick
High Anti-stripping alumina bricks are high-alumina bricks with anti-stripping properties produced by adding ZrO2 (zirconium dioxide) or other materials based on high-alumina clinker. The production process of anti-stripping high-alumina bricks is relatively complex, and the production is roughly divided into four stages: preparing the required raw materials—extrusion molding—high temperature forging—cooling and packaging.
Advantages of high Anti-stripping alumina brick
1. Anti-peeling high-alumina bricks have strong volume stability at high temperature
2. The product has a high softening temperature under load and does not shrink in volume
3. Anti-stripping high-alumina bricks have excellent thermal shock resistance
4. Anti-stripping high-alumina bricks are resistant to abrasion and do not produce structural spalling
5. High chemical resistance, no cracking
