Anti-stripping high alumina brick

  • Anti-stripping high alumina brick

Product Description And Parameters

High porosity, low the thermal conductivity

Good thermal shock resistance stability

Excellent heat resistant, good chemical stability

High purity high high alumina brick can contact to flame directly

Anti-sripping high 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-stripping as well as strong resistance to K, Na, S, Cl. Low thermal condutivity, which is the ideal material for the transition zone and decomposing zone for cement kilns.

Advantage of anti-stripping alumina refractory brick
a. High porosity, low the thermal conductivity.
b. Good thermal shock resistance stability.
c. Excellent heat resistant, good chemical stability.
d.High purity high high alumina brick can contact to flame directly.
