| Abstract: | Rotating blowing nozzle for blowing nitrogen refining aluminum alloy melt was upgraded to negate the pin-hole and inclusion defects in gravity casting aluminum components. The degassing and slag-removal effects were improved to refine aluminum alloy melt and to improve the quality of the component by refining N2 gas-bubble size to increase the contact area between N2 and aluminum melt. |
