What's the refractory alumina ball

The refractory alumina ball are mainly made of industrial alumina and refractory kaolin, processed by mixing, shaping and firing. It is specially utilized as the packing in thermal storage equipment and used in the air separation process and functions as a kind of heat exchange medium. It's specially applied as thermal storage packing in heat accumulator of air separation equipment, heating stove of blast furnace gas in the steel industry. During the process of steel rolling the  refractory alumina ball can preheat both air and gas so as to ensure burning temperature keep.
