Heat storage ball


The heat storage ball produced by our company has the characteristics of low shrinkage rate of re-burning line, high load softening temperature and strong corrosion resistance, especially in the process of heat storage burner change, the temperature drops rapidly and rises in the environment, the thermal shock stability is good, the amount of heat storage is large, and the occurrence of thermal shock crushing reduces ventilation or blocks the channel.
