Alumina bricks are alumina content of 48% neutral refractories, good thermal stability, refractoriness over 1770 degrees. Slag resistance is better. For masonry steelmaking furnace, glass furnaces, cement rotary kiln.
Similar alumina bricks and clay brick multi clinker production process, except that the ingredients in a higher proportion of clinker, up to 90 ~ 95%, clinker required before crushing and sieving grading picking iron sintering temperature high, generally 1500 ~ 1600 ℃ when such Ⅰ, Ⅱ and other high alumina brick tunnel kiln firing. Chinese production proved, high alumina clinker crusher strict selection before grading and classification storage, using a combination of clay and bauxite clinker together finely ground approach can improve the quality of products.
