Phosphate high alumina brick, High cold crushing strength, Good thermal shock resistance, Used in rotary kiln and cement kiln.

Description

Phosphate high alumina brick
High cold crushing strength
Good thermal shock resistance
Used in rotary kiln and cement kiln.
Phosphate brick is used as lining of cement rotary kilns, shaft kilns. Its performance is better than normal high alumina brick.
Phosphate brick has the features of high cold crushing strength, good thermal shock resistance, good wear resistant ability.

Characterastics,

Adding phosphate acid to ordinary high alumina bricks, through high-pressure molded and high temperature sintered form the product.

 

phosphate high alumina brick refractory has good temperature strength and volume stability, excellent slag corrosion resistance, high mechanical strength.  the phosphate bonded high alumina bricks are mainly used for preheating zone, high temperature zone and tuyere zone of rotary kiln and vertical kiln in cement industry,  as well as chemical industry, power industry and boiler industry.
