| Abstract: | The thermal cracks of casting defects are often observed when the semi-continuous casting process is applied to prepare the billets of high-strength wrought aluminum alloy.In this paper,the formation reason and influencing factors of thermal cracks were analyzed and the reasonable process based on the corresponding solution measures was established.The results show that the thermal cracking tendency of the casting billets is reduced by adjusting alloy composition,melting process and casting system. |
