Runner brick is a refractory brick for cast molten steel, hot metal,it requires good compactness, scouring resistance, good thermal shock stability,it has clay material, high aluminum material, mullite material,andalusite material.
Andalusite runner brick is research and development of advanced runner brick in recent years, it has excellent thermal shock resistance, high temperature, volume stability and good erosion resistance.
Andalusite runner brick used more frequently, cracking and spalling resistance is superior, the molten steel, hot metal pollution is small, more and more widely used by users.
