RH循环流量水模实验研究

Experimental Study on Water Modeling for Circulation Flow Rate in RH Degassing Refining

通过物理实验模拟考察了RH精炼过程中吹气量、吹气方式、真空度、气体行程等参数对循环流量的影响,并对实验结果进行了分析和论述,得出结论,吹气量低于120 m3/h时,循环流量随吹气量的增大而提高,多孔吹气、真空度升高及增加气体行程均有利于循环流量的提高。

The influence of these parameters such as blowing rate, blowing means, vacuum degree and air stroke on the circulation flow rate during RH refining was simulatively investigated based on the physical experiment. And then experimental results were analyzed and discussed.After that it is concluded that the circulation flow rate increases with increasing the blowing rate when the blowing rate is lower than 120 m3/h and blowing air through multihole supply, improving the vacuum degree and lengthening the air stroke are beneficial for increasing the circulation flow rate.
