Low Creep Refractory Brick Introduction
Low creep high alumina brick for blast furnace is made of corundum, mullite “sillimanite, andalusite and kyanite” and high quality bauxite clinker as raw material by shaping at high pressure and sintering at high temperature.
Low Creep Refractory Brick Application
The main markets for low creep high alumina brick are building lining of hot-blast stove, blast furnace, coke oven, rotary kilns of cement and so on.
