Product Description
refractory brick for ladle and refining furnace
Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.
Refractory brick 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.
