High Alumina TK-82/T-43 High Strength Refractory Brick For Aluminum smelting furnace electrolytic cell
High Grade Alumina brick is made of high bauxite clinker, brown corundum, andalusite and coke gem as the main raw materials, combined with high quality soft clay, formed by high pressure and sintered at high temperature. It is mainly used for the bottom of the melting pool of glass kiln and the middle and lower part of the regenerator.
▌FEATURES
1. High load softening starting temperature；
2. High compressive strength；
3.Strong permeability resistance
