Product Description
Product Overview:
Anti-stripping high-alumina brick is made of high-alumina bauxite clinker, mullite, kyanite, zircon sand, and binder through granulation and powder-making processes, mixed in a certain proportion, and then pressed into a high temperature Fired products with good anti-peeling properties. According to the physical and chemical indicators are divided into GKBL-70, KBL-70 two brands. Mainly used in cement rotary kiln, decomposition furnace, lime rotary kiln, nickel iron rotary kiln and other kiln.
