White color High Alumina Fire Proof brick anti-spalling refractory brick for cement kiln
High Alumina Anti- spalling Fire Proof Brick takes high grade bauxite as the main raw material, added into little ZrO2 (ZrO2 is a phase between monoclinic and square type, which can improve the thermal shock stability of the product), and added in a certain ratio of compound binders and additives, by controlling the grain size distribution of the plaster, molding and firing under high temp, this kind of product is with high spalling resistance. The spalling resistant mechanism is due to the fact that the microstructure of ZrO2 determined its anti-spalling performance.
High Alumina Anti- spalling Fire Proof Brick Features:
Strong anti spalling
Low thermal conductivity
Super thermal shock resistance
High Refractoriness Under Load
Good Chemical Attacking Resistant
High Alumina Anti-spalling fire proof Brick is widely applicaed to Transition Zone, Burning Zone and Calciner of Cement Rotary Kiln.
