Brief Introduction
Silica-mullite bricks is 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.

Application
Silicon carbide mullite bricks are widely used in basic industries such as iron and steel, non-ferrous metals, petrochemicals, machinery, electric power, and light industry. It can be said that the main application fields of refractory materials and their respective proportions account for the largest proportion in the iron and steel industry, followed by cement, ceramics, glass, chemicals, and non-ferrous metals. Specifically, silica mullite bricks are mainly used in the transition zone and calcination zone of cement rotary kiln and cooler.
Among them, AZM1650 is suitable for the preheating decomposition zone of the rotary kiln. AZM1680 is suitable for the transition zone of rotary kiln.
