Silicon Carbide Mullite Bricks
Silicon Carbide Mullite Bricks Introduction
Silica-mullite bricks mainly designed for rotary kiln of cement industry. Silicon mullite bricks by adopting high grade bauxite and SiC as raw material and special sintering process, silica-mullite bricks are characterized by high
strength, good performance of abrasion resistance and thermal shock resistance, constant forming protective layer for reducing accrection formation, long application cycle etc. Silica mulite fire bricks are used for the transition
zone, calcining zone of medium and small cement kiln.

Silicon Carbide Mullite Bricks Application Industry
Silicon Carbide mullite brick materials in the iron and steel, nonferrous metals, petrochemical, machinery, electricity, light industry and other basic industries have a wide range of applications. The main application areas of
refractory materials and their respective proportions in the steel industry accounted for the largest proportion. Followed by cement, ceramics, glass, chemical, nonferrous metals.
Silica mullite brick mainly used for the transitional zone & calcining zone of cment rotary kilns, and coolers.
AZM1650 is suitable to pre-heating decomposition zone of rotary kiln.
AZM1680 is suitable to the transitional zone of rotary kiln.
