Description

High alumina fire brick is a kind of refractory material with main component of Al2O3.

High alumina fire brick and clay brick production process is similar, the difference is that the proportion of clinker in the  ingredients is high, up to 90 ~ 95%. Before crushing, the clinker will be classified and selected to remove iron out, firing temperature is higher, Such as SK40, SK38 and other high-alumina brick firing temperature is generally 1500 ~ 1600 ℃ in the tunnel kiln.
Practice has proved that the strict selection, grading, and graded storage of high-alumina clinker before crushing, and the method of using bauxite clinker and combined clay co-fine grinding, can improve the quality of high alumina fire brick.

Category of  High Alumina Bricks:
a) According the made method, it can be divided into burnt brick, unburned brick, and electric smelting brick.
b) According the shape and size, it can be divided into standard brick, general brick and abnormal shape brick.
c) According the content of the Al2O3, it can be divided into fire clay brick and high alumina firebrick.
