Alumina bauxite of high quality are used as raw material combined with aluminum dihydrogen phosphate and finally dried in drying furnace. It has high refractoriness, good wear-resisting performance, high strength and good thermal stability, thus quite suitable for cement kiln transition zone and cooling zone lining material. With high RUL, accurate size and stable performance, such bricks have short construction period and energy saving.
