1,Description of Mullite Regenerative Ball
The product is mainly used for energy storage and heat storage of hot stove in steel plant. The product has high purity, high strength, good thermal shock stability and long service life,convenient replacement and cleaning.There are two methods of rolling and pressing, which are ceramic balls, porous balls and multi-hollow cylindrical balls.The product is especially suitable for regenerator of air separation equipment and blast furnace gas heating furnace of iron and steel plant as regenerative filler. By double preheating of gas and emptying, the burning temperature can quickly meet the requirement of billet heating in steel rolling.
