High-wearing chrome-Corundum Refractory Brick
High strength wearing-resisting Si-Mullite refractory brickAl2O3% ≥48% silica-alumina refractory brick, called High alumina brick. It is usually classified into 3 grades. Al2O3≥75%, 1st grade, Al2O3 % between 60-75%, 2nd grade, Al2O3% from 48-60%, 3st grade. Anti-Spalling High Alumina Brick is produced by adding the certain amount of ZrO2 content based on the common high alumina brick to increase the anti-spalling of the brick performance.
Usually as working line used in limestone kiln, electronic arc furnace, blast furnace, hot stove etc. Industry furnaces.
