High Alumina Refractory Bricks Introduction
High alumina brick is a kind of neutral refractory with alumina content above 48%. It is formed by shaping and calcining bauxite or other raw materials with high alumina content. High thermal stability and fire resistance above 1770 ℃. The production process of high alumina bricks is similar to that of multi clinker clay bricks. The difference is that the proportion of clinker in the ingredients is high, up to 90~95%. Before crushing, the clinker needs to be sorted and screened to remove iron. The firing temperature is high. For example, when high alumina bricks such as I and II are fired in tunnel kilns, it is generally 1500~1600 ℃. Raw Materials of High Alumina Bricks
According to the different resource situation and production requirement, adopt below several raw materials: high-alumina bauxite, sillimanite mineral and synthetic raw materials. There are abundant resources of high-alumina bauxite with fine quality in China.RS Company purchases raw materials only from our trusted suppliers that we have cooperated with for long term. All the raw materials shall be checked strictly upon they reached the factory. Each production process will be controlled strictly to ensure the quality and consistency so that providing customers with the best quality high alumina bricks.
