Data
High Alumina Refractory Checker Brick is an ideal insulating refractory refractory material, with advantages of high strength, low thermal conductivity, good insulation property and low price. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
High Alumina Refractory Checker Brick is also called high alumina insulating brick. It contains more than 48% Ai2O3 and mainly consists of mullite and glass phase or corundum. It is usually made of high bauxite and a small amount of clay. After the raw materials are grounded, it is made into mud. Then it is cast and molded and fired at 1300~1500℃. Sometimes industrial alumimum is used to replace bauxite. Inorganic matter is added as ignition loss substance in order to increase the porosity of the refractory.
1. According the shape, it can be divided into standard brick, special-shaped brick.
2. According thecharacteristic, it can be divided into high alumina insulating brick, fire clay insulating brick, Mullite insulating brick, corundum insulating brick, etc.
3. According the application, it can be divided into building materials for blast furnace, Building materials for coke oven, Building materials for steel making furnace and so on

ADVANTAGES OF ALUMINA LINING BRICK
1) High density and small thickness can increase the loading volume and promote the production capacity.
2) Low wear loss and long service life (it is 3-5 times compared with nature stone liner and 2-3times compared with rubber liner), which can reduce the installation times.
3) Main material is alumina which has no pollution to the grinding object.
Applications:
1. Furnaces of metallurgy industry, heat treatment furnace
2. Furnaces of chemical industry and construction industry.
3. Furnace of incineration of garbage, recirculating fluidized bed furnace
