- 摘要:
- 通过对大型薄壁叶轮的铸造工艺难点进行分析,采用三维软件绘制,利用模拟软件对铸造工艺优化设计,对双相不锈钢钢叶轮铸造生产过程进行了数值模拟研究。结果表明,通过分析可能产生铸造缺陷的位置及类型,优化铸造工艺并进行了数值模拟计算,实现了虚拟试铸,可以有效地改善热节状态,达到消除和控制缺陷的目的,使铸件能够达到质量要求。
Based on the analysis of the casting process difficulties of large thin-wall impeller,the casting process was optimized by using 3D software and simulation software,and the casting process of dual-phase stainless steel impeller was numerically simulated.The results show that by analyzing the location and type of casting defects,optimizing the casting process and carrying out numerical simulation calculation,virtual trial casting can effectively improve the hot spot state,achieve the purpose of eliminating and controlling the defects,and make the casting meet the quality requirements.
