Introduction of refractory corundum brick

Alumina content of more than 90%, with corundum brick as the main phase of the refractory products. Very high room temperature compressive strength (up to 340MPa). High load softening start temperature (greater than 1700 ℃). Good chemical stability, acidic or alkaline slag, metal and glass, etc. have a strong resistance. Thermal shock stability is related to its microstructure, and the corrosion resistance of dense products is good, but the thermal shock stability is poor. Divided into sintered corundum brick and fused corundum brick two. Can be sintered alumina and fused corundum brick as raw materials or Al2O3 / SiO2 than the high bauxite clinker with sintered alumina, made by sintering method. Can also be made of phosphoric acid or other binders do not burn corundum bricks. Mainly used for blast furnace and blast furnace hot stove, steel furnace refining furnace, sliding water heater, glass melting furnace and petrochemical industry furnace. See the color of magnesium chrome brick black and red, clay high alumina brick yellow, black brick red and yellow, silicate brick beige, light, carbon and silicon carbide products black, fused corundum brick and mullite materials White or gray. See the density, high alumina brick density is generally 2.3-2.7, clay brick 2.2-2.4., Silicon brick 1.8-2.0., Magnesia brick and magnesia-chrome brick 2.9-3.1, the general density of high-melting, are more than 3.1, Section tidy, the rest of the light brick would not have said, Dian Dian know it
