EXPERIMENTAL STUDY ON THE BEHAVIOR OF INCLUSIONS IN RH DEGASSER
RH真空精炼装置内夹杂物行为的实验研究

The effects of treatment time, lift gas flow rate and liquid height in vacuum vessel on inclusion removal in RH degasser were investigated by choosing emulsion drops simulated as inclusions in a water model. The results show that most of the inclusions can be removed after treatment for 12 min, and all the inclusions which can be removed almost disappeared from the system after treatment for 24 min. Larger lift gas flow rates seemed to be more efficient for inclusions removal and there is a lift gas flow rate for the best of inclusions removal (20 L/min for this work). The liquid height in vacuum vessel has also an optimized value for inclusions removal (46 mm for this work).
