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