Superior High Alumina Refractory Brick

Product Description

With years of practice of this area, we are indulged in exporting, manufacturing and supplying an excellent quality collection of Superior High Alumina Refractory Brick in Zhengzhou, Henan, China. Use of high alumina bricks:Mainly used for masonry blast furnace, hot stove, electric furnace top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina bricks are also widely used to do flat furnace regenerative lattice brick, pouring system with the plug head, water tank and so on. Features: First, refractoriness. High alumina brick refractoriness than clay brick and semi-silica brick refractoriness should be high, up to 1750-1790 a , are high-grade refractory materials. Second, the load softening temperature. Because high-alumina products in the high Al2O3, less impurities, the formation of fusible glass less, so the load softening temperature than clay brick, but the mullite crystallization does not form a network of organizations, so the load softening temperature is still no silicone bricks. Third, the slag resistance. High alumina brick Al2O3 more close to the neutral refractory material, can resist the acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkali-resistant slag than the ability of acid-resistant slag weak.
