Product Description

High strength high alumina bricks for cement and lime industry with aluminum oxide (Al2O3) content higher than 48%. High strength high alumina bricks for cement and lime industry is a neutral refractory material with an alumina content of more than 48%. High strength high alumina bricks for cement and lime industry is formed and calcined from bauxite or other raw materials with high alumina content. High thermal stability, refractoriness above 1770℃. High strength high alumina bricks for cement and lime industry has good slag resistance and is used to build the lining of steel-making electric furnaces, glass melting furnaces, cement rotary furnaces, etc. The production process of high-alumina brick and multi-clinker clay brick are similar. The difference is that the proportion of clinker in the ingredients is higher, which can be as high as 90-95%. The clinker needs to be sorted and sieved to remove iron before crushing, and the firing temperature Higher, such as Ⅰ, Ⅱ high alumina bricks are generally 1500～1600℃ when they are fired in tunnel kiln.

Application

High strength high alumina bricks for cement and lime industry are mainly used for the lining of blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kilns. In addition, High strength high alumina bricks are widely used in open-hearth regenerated lattice bricks, gating system plugs, nozzle bricks, etc., but the price of high alumina bricks is higher than that of clay bricks, and High strength high alumina bricks do not need to be used where clay bricks can meet the requirements.
