| Abstract: | This article analyzes formation mechanism of 4004 aluminum alloy ingot the blowhole and explains why it is happened.Then elaborates the methods to reduce the amount of gas in melts through the adoption of extended refining time,increased standing before alternation,taking a three-rotor degassing device,increase the casting temperature and other measures.it is also to be proved all the measures are effective by the surface quality of ingots before and after comparison. |
