【摘要】 分析了机尾滚筒的结构特点,建立机尾滚筒的三维实体模型,并对机尾滚筒消失模铸造工艺进行部分改进。运用华铸CAE软件对原浇注工艺方案和改进后的工艺方案进行凝固过程模拟分析。结果表明,改进后的工艺不但能简化制模过程及冒口去除过程,且对铸件进行有效的补缩,缩孔缩松等缺陷得到明显的改善。更多还原

【Abstract】 The structure characteristics of the tail roller were analyzed, the 3D solid design of the tail roller was built and the EPC process was improved partially. The solidification process for both the original casting process and the improved casting process were simulated by using Huazhu CAE. The results show that the improved process will not only simplify the pattern process and riser removal process, but also increase the feeding efficiency and eliminate the shrinkage porosity defects in the casting.更多还原
