Product Description

Spalling Resistance High Alumina Refractory Brick for Cement Kiln
The Description:
Anti-spalling high alumina brick is referred to as anti-spalling brick or anti-spalling refractory brick. Using high bauxite clinker as the main raw material, the introduction of a small amount of ZrO2(because ZrO2 is a monoclinal and quadrangular phase change, can improve the thermal shock stability of refractory bricks), adding a certain amount of composite binder and additives, by controlling the size of the mud, by molding and high temperature fired refractory products become anti-spalling high aluminum bricks.
