Product Description

Description:
Luzhong Magnesia alumina spinel bricks are new developed chrom free refractories for Cement Rotary Kiln. In order to serve under severe conditions,LZR magnesia-alumina spinel bricks have excellent mechanical strength, good resistance to thermal shocking, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design MLJ85FH bricks to meet the requirements of cement rotaty kiln lower the load and mechanical stress. With excellent performance,our products have been widely used in the domestic and overseas cement projects.

Characteristics:
Excellent chemical corrosion resistance
Lower load and mechanical stress to the kiln shell
Outstanding wear resistance
Low thermal conductivity
Excellent thermal shock resistance


Application: 
Transition zone of cement rotary kiln.
