Standard Size SK35 SK36 SK37 SK38 SK40 Types of High Alumina Firebrick Aluminium OxideBrick For Sale
High alumina bricks, available for purchase at RS Company, are a prevalent type of refractory material. They are primarily composed of Al2O3. These bricks possess attributes such as elevated refractoriness, robust strength, resistance to acid and abrasive erosion, as well as commendable thermal stability. Notably, they exhibit exceptional thermal stability and can withstand temperatures exceeding 1770℃.
The manufacturing procedure for high alumina bricks bears resemblance to that of multi-clinker clay bricks. However, the key distinction lies in the substantial proportion of clinker in the constituents, reaching as high as 90-95%. Prior to pulverization, the clinker necessitates thorough sorting and screening to eliminate any iron impurities. Furthermore, the firing process demands elevated temperatures. For instance, in the case of high alumina bricks like Grade I and II being fired in tunnel kilns, temperatures typically range from 1500 to 1600 ℃.
