Factory direct high-quality corundum burning plate, push plate corundum, corundum mullite push plate

Alumina content greater than 90%, with corundum crystal phase refractory products. High compressive strength at room temperature (up to 340MPa). High load softening start temperature (greater than 1700 ℃). Good chemical stability, acidic or basic slag, metal and glass fluid, etc. have a strong resistance to thermal shock related to its organizational structure, good resistance to erosion dense products, but poor thermal shock resistance . Divided into two sintered corundum brick brick and fused corundum. Respectively sintered alumina and fused alumina or bauxite and sintered alumina Al2O3 / SiO2 ratio of fit into the legal system by sintering. Can also be made of phosphoric acid or other adhesive does not burn corundum brick. Mainly used outside blast furnaces and hot blast furnace, steel refining furnace, water slide, glass melting furnaces and furnace oil and chemical industry.
