SK - 38 Yellow Color Kiln Fire Bricks Contain 70% Al2O3 ,
Customzied Size
Description:
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.
Features:
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.
