摘　　要：针对5754铝合金在熔铸过程中投入三级碎屑及使用陶瓷片或未投入三级碎屑及未使用陶瓷片结果的对比,研究铸锭内部组织、机械性能的影响。结果表明:即使投入三级碎屑,但增加除气除渣操作,其铸锭的组织和性能也能达到或超过未使用三级碎屑的铸锭。In this paper, we contrast the result of putting grade Ⅲ debris into 5754 aluminum alloy and using ceramic in the casting process with not putting grade Ⅲ debris into and unusing ceramic.Research the influence on the internal organization and mechanical properties of the ingot. The results showed that： even if put grade Ⅲ debris into, but add to the operations of degasifying and deslagging, the organization and performance of its ingot can also meet or exceed the the ingot of unused grade Ⅲdebris.
