摘要
利用华铸CAE软件对YL14000B型烟机轴承箱体的充型凝固过程进行了模拟分析,预测了该铸件原铸造工艺存在冒口过大而导致的补缩过剩、后轴承座热节处存在集中缩孔、底座热节处存在疏松等缺陷。通过采取减小冒口尺寸、增加热节处内冷铁数量和加宽补缩通道等措施;再次进行CAE数值模拟,发现上述缺陷得到了有效消除。实际生产结果表明,冒口根部无集中缩孔,铸造工艺出品率由61%提高到了71%,节约钢液660kg,降低了生产成本,铸件质量也得到了提高。
Through numerical simulation of the mould filling and solidification process of YL14000B expander bearing-box by InteCast software, it was forecasted that the risers were residual, and the defects existed such as shrinkage in the behind bearing base and microshrinkage in the bottom base according to the original process. Through taking the measures of decreasing the size of risers, setting more inner chills, widening the feeding channel of molten steel, the CAE numerical simulation results show that the defects of shrinkage and microshinkage were eliminated effectively. There was no concentrated shrinkage at the bottom of the risers in practical production. The process yield was enhanced from 61% to 71%, and molten steel saved was 660 kg. Meanwhile, the production cost was reduced and the casting quality was improved.
