Sillimanite Special Brick

Because sillimanite refractories have high thermal shock stability, resistance to erosion of molten glass, and less pollution to molten glass, sillimanite special-shaped products are mainly used in glass industry feeders, pipe drawing machines, and other equipment, which can significantly improve production effectiveness. The products mainly include spouts, orifice rings, stirrers, plungers, tubes, and spout covers.
