■ Application:
The DuraTec thermal storage ceramic ball is specially utilized as the packing in thermal storage equipment. it is 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 equipments, heating stove of blast furnace gas in the steel industry. During the process of steel rolling, if thermal storage ball is installed, it can preheat both air and gas so as to ensure burning temperature achieve the requirement quickly required by heating of billet during steel rolling.
