Features: Andalusite refractory brick formed at 1350 ℃ mullite to make the surface of the product with a strong “weldability” effect, so that the product has better on the aspect of thermal shock stability, load softening temperature, high temperature creep performance, thermal shock resistance r.
Applications: is the Dutch-style hot stove with the characteristics of refractory materials.
