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 brick is a kind of refractory , whose main component is Al2O3. For example, Al2O3 is high than 90$, called as corundom brick. Because of different resources, different countries have different standards. For example, European countries regulate that the lowest limit of Al2O3 is 42%. And in China, high alumina brick is divided into three classes based on Al2O3 component. Ⅰclass──Al2O3 >75%；Ⅱclass──Al2O3 is about 60～75%；Ⅲ class──Al2O3 is about 48～60%. Mainly used for masonry blast furnace, hot stove, furnace top, blast furnace, reverberatory furnace, rotary kiln lining. In addition, high alumina brick is also widely used as open hearth regenerative checker bricks, gating system with plug head, outlet brick. But the price of high-alumina brick clay brick than high, so with clay brick to meet the requirements of the place do not have to use high-alumina brick.

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...
