Anti-Spalling High Alumina Refractory Brick

Anti-Spalling High Alumina Refractory Brick used in the transition zone and decomposition zone of the medium and large cement rotary kiln.



Product Details


Anti-Spalling High Alumina Refractory Brick

 

Made of the high grade bauxite clinker as the main material, adding a mall amount of ZrO2 fine powder( As ZrO2 material present the phase transition from the monoclinic phase and tetragonal phases, that can increase the thermal shock stability of the products. Then adding the certain of bonding and additive agent, then high-presser pressing and high temp. Sintered.

 

Anti-Spalling High Alumina Refractory Brick Feature

 

High spalling and corrosion -resisting at high temperature state, low thermal conductivity,  strong thermal shock stability, etc. Features.

 

Anti-Spalling High Alumina Refractory Brick Application

 

Ideal refractory material used in the transition zone and decomposition zone of the medium and large cement rotary kiln.
