The sintering temperature of the anti-stripping high alumina brick should be controlled below 1450℃.
The anti-stripping high alumina brick has excellent thermal shock stability, high load softening temperature, high high temperature strength, alkali resistance and clinker erosion, certain mechanical strength, high temperature wear resistance, peeling, anti-skinning, ring formation and heat conduction Comprehensive characteristics such as low coefficient and long service life.
The sintering temperature of the anti-stripping high alumina brick should be controlled below 1450℃. During the sintering process, the high alumina bauxite reacts with the added zircon to form mullite and zirconia, and cracks due to the phase transformation of zirconia , Obtained suitable compressive strength and high thermal shock resistance.
