Andalusite high alumina brick has high load softening temperature, good resistance to rapid cooling and heating, strong impact resistance and high creep resistance. Andalusite high alumina brick is made by taking Andalusite as the main raw material, adding bauxite, high-pressure molding and firing at 1500 ℃. During use, the thermal expansion coefficient is low, the thermal conductivity coefficient is low, and the volume stability performance is high, which improves the overall compactness of the masonry and thus improves the slag permeability resistance.
