运用传统方法完成了十字头铸钢件的铸造工艺设计,根据铸件的结构特征和相关技术要求,采取底注式系统进行浇注。利用Pro/Engineer软件对铸件进行三维建模,并用ViewCast软件对其凝固过程进行数值模拟。通过凝固模拟结果的分析,逐步改进冒口和冷铁系统,优化原有的工艺设计方案,从而获得了相对合理的铸造工艺,达到了减少铸件缺陷和提高铸件工艺出品率的目的。
The traditional method was used to design the casting process of the crosshead castings. According to the structural characteristics of the castings and the related technical requirements, a bottom-in-place system was used for casting. Casting is modeled using Pro / Engineer software and the solidification process is numerically simulated with ViewCast software. Through the analysis of solidification simulation results, the riser and chilled iron system are gradually improved, the original process design is optimized, and a relatively reasonable casting process is obtained, thereby reducing the defects of castings and improving the yield of castings.
