| Abstract: | Rotary impeller degassing has been used to refine ZL114A alloy, The parameters of the refining equipment has been settled with comparing effect of different impeller rotation speed and flux of Ar2, the rule of content of H2 with refining time has been studied, and the best process parameters of rotary impeller degassing has been carried out. The content of Mg before and after refinement has been compared and the mechanical properties of ZL114A after refiment has been tested, the results indicate that the reduction of content of Mg is very low, the mechanical properties of ZL114A after refiment is high. |
