Product Overview
Description
High alumina brick
Product Description
High aluminium brick depends on its 3 oxidation 2 aluminium (Al2O3) content how many distinction, at present often apply have 48%, 55%, 60%, 65%, 73%, 75%, 80%, etc.
According to the content of how much 55 below called clay brick, is a kind of neutral refractory, made by bauxite or other materials with higher alumina content molding and fired.High thermal stability, refractory temperature at 1700°C, used in glass furnaces, cement rotary kiln, steel furnace lining.Of course, there are some with high charge soft, low creep, low porosity of high aluminum clay brick, high aluminum brick finished products, according to the use of different needs in the production of temporary ratio of raw materials is crucial.
And high alumina bricks and clay brick is not only alumina content, their production process are similar, but in the mixed with guess clinker is higher, can reach 90-95%, sintering temperature is much higher than clay brick, in the actual test secondary high alumina bricks are mostly is used in the 1500-1600 ° C temperature tunnel kiln, blast furnace, furnace top, reverberatory furnace, rotary kiln lining etc. A lot of kiln.
