What is Alumina Refractory Brick

Alumina refractory brick is a refractory brick made from alumina refractory material, which is prepared by adding powder, additive and binder and high pressure forming of mixed material. Compounds of alumina is a kind of high hardness, which melting point is 2054 ℃, boiling point is 2980 ℃, at high temperatures can be ionization ion crystal, commonly used in production of refractory materials, which is more common synthetic corundum.

Alumina Refractory Brick Classification

. According to volume density: heavy alumina refractory brick and light alumina refractory brick.

. According to the content of alumina: less than 42% of alumina refractory brick is clay firebrick; 42-80% alumina refractory brick is high alumina refractory brick. 80% alumina refractory brick is corundum refractory brick.

. According to dimensions and specifications, it is divided into standard alumina refractory brick, straight brick, knife edge brick, arch foot brick, arch top brick and other special-shaped firebrick.

Use of Alumina Refractory Brick

Alumina refractory brick can be used in blast furnace, hot air furnace, coke oven, electric furnace, heating furnace and other industrial kilns such as iron smelting, steelmaking and rotary kiln.

Above is the simple introduction of alumina refractory brick, when you need choose and buy alumina refractory brick, must be sure to tell production factory, the alumina content of alumina refractory brick, the use of environmental indicators such as information, because the alumina content is different, the price difference is very big, so this is what alumina refractory brick is a simple introduction, know more information about alumina refractory brick can contact RS anytime.
