Process: Vibration molding. The special refractory castable is placed in specifc moulds, vibrated with a large flat vibration table, and the semi-finished product is dried and fired at high temperature, and then processed by cutting and grinding.

Main raw materials: The flint clay(particles) produced in Zibo, Al203 content is about 44%,Fe2O3<2%.The composition is stable, the texture is uniform, the structure is dense, the section is shell-like and white.and it is used for the production of high-quality clay refractories.

Performance :Good resistance to glass liquid corrosion and alkall corrosion

　　　　　　　No peeling

　　　　　　　Good therma lshock stability

　　　　　　　High machining accuracy and easy installation

　　　　　　　Its physical and chemical indicators and appearance are better than national standards

Uses: Used for glass furnace bottom,float glass furnace tin tank bottom,glass electic furnace and other parts.
