thermal storage ball used in blast furnace 1.heat exchange medium 2.high abrasion resistance 3.high thermal conductivity
Thermal Storage Ceramic Ball
Introduction: The thermal storage ceramic 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 can work at temperatures ranging from0-1700.C. A qualified thermal storage ceramic ball should come with a smooth surface and should be spotless, crack free and flawless.
Product Feature: With the smooth surface, thermal storage ball owns the characters of high mechanical strength, high abrasion resistance, high thermal conductivity & thermal capacity, high thermal stability, and excellent heat endurance. There are three types, including ceramic ball, porous ceramic column and porous ceramic ball. 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.
