Abstract
Effects of different degassing processes on molten aluminum and on the modification efficiency of different modifier with Na and Sr were investigated.The results show that the rotating-injection argon gas degassing technology combining with the salt degassing can improve the molten aluminum degassing efficiency
and the rotating-injection argon gas degassing technology combining with the Na salt refining process can decrease the H2 absorption during refining process.In addition
the rotating-injection argon gas degassing technology can reduce the strontium burning in the molten aluminum
improving the modification efficiency of strontium.
