Application of high alumina brick

High alumina brick is a kind of aluminum silicate refractory brick with alumina content of more than 48%. High alumina brick is mainly made of high alumina bauxite as refractory raw material, added with other powders and binders, mixed into brick making machine, pressed and formed, dried and fired in high-temperature tunnel kiln.

What are the uses of high alumina bricks?

High alumina brick has a wide range of refractory raw materials and stable characteristics. As the basic material in the field of high temperature technology, it is applied in cement, glass and building materials industry, iron and steel smelting industry, petrochemical industry, etc; High temperature industrial kilns used for high alumina bricks include blast furnace, hot blast furnace, electric furnace top, blast furnace, reflection furnace and rotary kiln lining. In addition, high alumina bricks can also be processed into open hearth regenerative lattice bricks, plugs for gating system, nozzle bricks, etc. according to the needs of industrial kilns, and high alumina refractory bricks of various shapes can also be produced and processed according to the drawings required by customers.

The physical and chemical indexes of high alumina refractory bricks are different, and the uses of high alumina refractory bricks are also slightly different. Taking the common bulk density as the standard, high alumina refractory bricks are 2.1g/cm3, 2.2g/cm3, 2.3g/cm3 and 2.4g/cm3. If used in the same high-temperature industrial kiln, high alumina refractory bricks with different bulk density need to be used in different parts.

Macroscopically speaking, high alumina refractory bricks can be used in a variety of high-temperature industrial kilns. Microscopically, high alumina bricks with different physical and chemical indexes are used in different parts of the same high-temperature kiln.
