Thermal ceramic ball resistance high temperature

Products introduction:

Thermal storage ball has the advantages of high strength, wear resistance; high thermal conductivity and heat capacity, high heat storage efficiency; good thermal stability and not easy to break when the temperature changes suddenly. The Thermal storage ceramic ball is especially suitable for the heat storage filler of air separation equipment and blast furnace gas heating furnace of steel plant. Through double preheating of gas and air, the combustion temperature can quickly reach the demand of steel rolling for heating billet.
