Highalumina insulating refractory brick refers to the use of bauxite as the main raw material, made of Al2O3 content of not less than 48% of insulating fire bricks. Highalumina insulating refractory bricks can be used for masonry insulation layer in thermal furnaces, not directly contact with flame. Generally, the surface contact temperature should not be higher than 1350 ℃.
Brief Introduction of Highalumina Insulating Refractory Brick
Highalumina insulating refractory bricks, mainly using bauxite clinker, combined with clay as raw materials, mixed with binder and sawdust. In order to improve insulating fire bricks product performance, adding fine powders of industrial alumina, corundum, sillimanite, kyanite and silica can produce refractory brick products with a bulk density of 0.4g/cm3 or more. Al2O3 content and volume density are different, and the maximum use temperature is also different. The service temperature of Highalumina insulating refractory bricks is usually 1250-1350 ℃. Under certain circumstances, the use temperature of some aluminum insulating refractory brick can reach 1550 ℃.
High Aluminum Insulating Refractory Brick Application
High Aluminum Insulating Refractory Bricks can be used for masonry insulation and parts without strong high temperature molten materials erosion. When directly in contact with the flame, the surface contact temperature of general High Aluminum Insulating Refractory Bricks shall not be higher than 1350 ℃. Mullite insulating refractory bricks can directly contact the fire filling, with high temperature resistance and high strength. Features such as significant energy saving effect. Suitable for insulation lining of pyrolysis furnace, hot air furnace, ceramic roller kiln, electric porcelain drawer kiln and various resistance furnaces. Corundum-mullite insulation refractory brick with Al2O3 content of 82.4% can be used as lining at 1550 ℃.
