Detail

INTRODUCTION:
Magnesia spinel bricks are refractory products made of periclase and magnesia alumina spinel ,which can improve the heat stability of common magnesia brick.
 
FEATURES:
1.Excellent heat stability.
2.Better anti-stripping performance than direct bonded magnesia chrome brick.  
3.Abrasion resistant.
4.High refractoriness under load.
 
APPLICATION:
It’s mainly used for burning zone and transition zone of cement kiln, also some other industrial furnaces.
