Description
Phosphate bonded high alumina brick is a kind of refractory brick made primarily from high alumina bauxite clinker, corundum, and mullite, using a phosphate chemical bonding process. This product features high pressure resistance, low porosity, excellent thermal shock stability, good wear resistance and strong anti-peeling ability.
Advantages of Phosphate Bonded High Alumina Brick
• High Strength and Wear Resistance
Phosphate bonded high alumina brick has high cold crushing strength and good abrasion resistance, making it suitable for furnace zones exposed to mechanical wear.
• Corrosion Resistance
The dense phosphate-bonded structure helps resist slag erosion, chemical corrosion and material attack under high-temperature service conditions.
• High R.U.L and Low Creep
It maintains good load-bearing performance at high temperature and reduces deformation in long-term furnace operation.
• Thermal Shock Stability and Anti-Stripping
Good thermal shock resistance helps reduce cracking, peeling and spalling caused by repeated heating and cooling, supporting longer lining service life.
