Product Description
Luzhong Magnesia Alumina Spinel Compound Bricks are new developed chrome-free refractories for Cement Rotary Kilns, with excellent performance,our products have been wide used in the domestic and overseas cement projects.
Characteristics:
1.Excellent resistance to chemical attack
2.Excellent thermal-shock resistance
3.Excellent abrasion resistance
4.Low thermal conductivity (230-280ºC)
5.Reducing the load and mechanical stress to the shell body
Application zone: Transition zone of cement rotary kiln.
Raw Material:
1.Synthetic Light-weighted magnesia spinel,
2. Alumina-magnesia spinel
Physical and chemical index
