refractory ball
1.Characteristics:
Refractory ball is named heat-storage ceramic ball which is featured with high strength, wear resistance, large thermal conductivity ,heat capacity, good heat storage and heat stability etc. It can pre-heat both coal gas and air to rapidly increase the combustion temperature to meet the billet heating requirement in steel rolling equipment. Furthermore, it is not easy to crack when the temperature changes sharply.
2.Application:
It is especially applicable as heat storage packing of heat accumulators of air separation plants and gas heating stoves of blast furnace in steel plants.
