High wear-resistant brick
product Overview:
Silicon mullite brick is andalusite, brown corundum, high-alumina bauxite clinker, silicon carbide, and binder. After granulation and flour milling, they are mixed in a certain proportion, and then pressed into shape. , High strength, low thermal conductivity, strong flexibility, moderate density, high wear resistance products. Mainly used in cement rotary kiln transition zone and kiln mouth, lime rotary kiln, nickel iron rotary kiln and other kiln.
