SK Series Brick Refractory Fire Bricks AL2O3% (≥) 75 Refractory Material



Anti-stripping alumina brick was produced with special bauxite chamotte, adding aragonite or ZrO2 and pressing under high pressure based on a certain ratio. It has strong Anti-stirping as well as strong resistance to K, NA, S ,CL, low thermal conductivity, which is the ideal material for the transition zone and decomposing zone for cement kiln.


1. High refractoriness.

2. Good spalling resistance and wear resistance.

3. Good corrosion resistance.

4. Good thermal shock resistance.

5. High mechanical strength.

6. High-temperature creep rate is low.
