Alumina brick is a kind of refractory material. The main component of high alumina brick is Al2O3. High alumina brick is a alumina trioxide (Al2O3) content higher than 48% alumina silicate refractory products . It is made from bauxite or other refractory raw materials with high content of alumina through forming and calcining with thermal stability, high refractoriness in more than 1770 ℃. High alumina brick has good slag resistance and is used for lining of steel making electric furnace, glass furnace and cement rotary furnace. Wanhao is a manufacturer who is specialized in designing various kinds of furnace and making refractory products for electric furnace, ladle, tundish, blast furnace, AOD furnace, IF furnace, etc. Article Source: The feature of high alumina Brick Company name：Wanhao Refractory Email:sales100@wanhaorefractory.com Website: http://www.wanhaorefractory.com/

High alumina refractory bricks , also known as high alumina brick, and its production and stickers brick production process is similar to the difference is more with high-alumina clinker powder, refractoriness than clay brick, anti-acid and alkali resistance candle better performance It is used in various kiln firing zones. Al2O3 content of more than 48% of the aluminum silicate   refractory   bricks are collectively referred to as high alumina refractory bricks. (Al2O3 is 60% ~ 75%); Ⅲ and so on (Al2O3 is 48% ~ 60%). The Al2O3 content is divided into three grades: I and so on (Al2O3> 75%); According to the mineral composition can be divided into: low mullite (including sillimanite) and mullite (Al2O3 for 48% ~ 71.8%), mullite - corundum and corundum - 71.8% ~ 95%), corundum (Al2O3 95% ~ 100%) and other refractory bricks. With the increase in Al2O3 content in   high alumina bricks , the number of mullite and corundum components also increased, the glass phase de...
