Refractory material

       Commonly used refractories for glass furnaces are mainly divided into four categories: fused cast refractories, sintered refractories, unshaped refractories and insulating refractories. Each type of material contains several types. The technical requirements of the chemical composition, physical function, scale error and appearance quality of the refractory materials should conform to the national or industry standards, and the newly revised version should be used, otherwise the factory should not be allowed to leave the factory.
