Refractory Brick in stock High-alumina bricks suitable for cement kilns mainly include phosphate-bonded high-alumina bricks, phosphate-bonded high-alumina wear-resistant bricks, and anti-stripping bricks. High-alumina bricks, chemically bonded (special) high-alumina bricks, and ordinary high-alumina bricks, etc. Advantages and characteristics of high alumina bricks for cement kilns 1) High refractory temperature. 2) 0.2MPA load softening temperature is greater than 1500 degrees. 3) Excellent thermal shock resistance, more than 25 times of water cooling at 1100 degrees. 4) High compressive strength at room temperature, greater than 60MPA. 5) The apparent porosity is low, and the volume is stable at high temperature. 6) Excellent anti-stripping performance. 7) Good chemical resistance. The use of anti-stripping high-alumina bricks Anti-stripping high-alumina bricks are widely used in my country's new dry process kiln, Libore kiln and wet process kiln, including kiln door cover, rising flue, cooling zone, decomposition zone, safety belt, transition zone, coolant rear Walls and side walls and beams with curved ceilings.
