Refractory ceramic ball is made of industrial alumina and other raw refractory materials. With the process of mixing, shaping and firing, the characteristic of high strength and long working life, high chemical stability, never react with the feeding materials, excellent resistance to high temperature up to 1900. Hq-rf refractory ceramic balls can be used for supporting and covering packing for catalyst in shift converter, reformer, hydro converter, desulfurizer, and methanator, and can also be used for packing in hot blast heater and heat transformer in iron industry.
