摘　　要：本文通过低倍组织观察、合金元素化验及合金铸造过程仿真模拟等方法,分析了锻压轮毂用6061铝合金圆铸棒生产过程中出现中心裂纹缺陷的原因,并采取调整配料、优化熔炼和铸造工艺等相应改进措施消除了产品缺陷。经生产实践,锻压轮毂用6061铝合金圆铸棒质量持续稳定,满足了高端锻压轮毂用材的要求。This study analyzes the causes of center crack defects in the manufacturing process of 6061 aluminum alloy billets for forged hubs though various methods,including low-magnification microstructure observation,alloying element tests and alloy casting process simulation.In order to rectify these defects,the corresponding improvement measures are adopted,such as adjustment of proportion,optimization of the melting and casting processes.The practical production shows that the quality of 6061 aluminum alloy billets for forged hubs remains consistently stable,thus satisfying the demands for materials used in high-end forged hubs.
