摘要
本文应用相似理论设计了水力模拟实验，研究了铝合金炉外连续处理单元的小熔池中旋转喷吹除气．结果表明：采用Φ（２００～３００）ｍｍ熔池，熔体深度（３００～３６０）ｍｍ，Φ６０ｍｍ多孔叶片式旋转头，在转速为７００ｒ／ｍｉｎ时可以得到理想的除气效果．
Based on the principle of simlitude, hydrodynamic modelling experiment has been developed to study the dynamic degassing of aluminium alloy melt with rotary impeller in small meltingpot of inline cleanup system. The results show that, using a Φ 60 mm multihole bladed degassing rotor in a Φ (200~300) mm meltingpot with depth (300~360) mm, under the gas flowrate of 0.177 m 3/h and rotating speed of 700 r/min, the degassing result is ideal.
