High-wearing chrome-Corundum Refractory Brick
High strength wearing-resisting Si-Mullite refractory brickMade 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.
Ideal refractory material used in the transition zone and decomposition zone of the medium and large cement rotary kiln.
