The Purification of ZL114A Alloy by Means of Bubble Floatation

Abstract:

According to the principle of bubble floatation, purification of ZL114 aluminum casting alloy has been studied by blowing nitrogen gas into the ZL114A alloy melt through the porous plug which can produce dispersed micro bubbles. 5 samples have been taken at 0 min, 2 min, 4 min, 6 min, 8 min and 10 min, respectively, to measure the hydrogen content through HYSCAN II hydrogen tester. The experiments results show that the removing effect of hydrogen is remarkable. The hydrogen removing efficiency reaches 85.7% when blowing lasts 4 minutes. The rate of hydrogen removing begins to decrease from 4 minutes to 10 minutes; the hydrogen removing efficiency gets to the maximum after 8 minutes. The inclusions are also removed with the removal of hydrogen.
