High Alumina 80% Al2O3 Straight Brick
Straight brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, straight brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.
Straight bric has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.
Linquan series alumina bricks are high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content.
