The sillimanite and mullite refractories are featured with high refractoriness, good thermal stability, resistance to glass liquid erosion, and low pollution to glass liquid. They are the most common refractories used in feeders, tube drawing machines, and other equipment in the domestic and foreign glass industry, which significantly improve productivity. The products include feeder channel bricks, pot spouts, mandrel, spouts, orifice rings, stirrers, needles, feeder sleeves, skimmer blocks, damper bricks, front arch bricks, rear arch bricks, spout covers, burner bricks, lintel, cover plate bricks, and muffle furnace bricks, there are hundreds of products and specifications. The sintered fused mullite and corundum mullite products also featured with low creep rates at high temperature and better physical and chemical properties, so they can be used in the superstructure and heat storage room of glass kilns such as borosilicate glass and glass fiber.
