摘　　要：以镁合金轮毂铸件为例,完成了从铸件结构设计到铸造毛坯件小批量生产的整个系统工程,总结了镁合金铸件常见缺陷的影响因素,提出了减少缺陷的改进措施。结果表明,通过系统分析,调整设备操作和工艺参数,可以很大程度上减少缺陷,对镁合金铸件生产,提高成品率具有重要意义。Taking the magnesium alloy hub casting as an example, the whole system engineering from the structural design of the casting to the small batch production of the casting blank was completed. The influencing factors of common defects in magnesium alloy castings were summarized, and the improvement measures to reduce the defects were put forward. The results show that the defects can be greatly reduced by systematic analysis and adjustment of equipment operation and process parameters, which is of great significance to the production of magnesium alloy castings and the improvement of yield.
