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 ℃.
