对压缩机十字头铸造工艺进行分析,选择了合适的浇道位置和分型面。在此基础上,基于计算机仿真技术,利用Procast铸造成型软件模拟球墨铸铁十字头铸造成型过程以优化十字头铸造工艺。设计了充分利用球墨铸铁共晶膨胀作用而实现自补缩的冒口,使得十字头表面质量与内部缺陷均得以改善,并在很大程度上提高十字头的铸造效率。 Compressor crosshead casting process analysis, select the appropriate position and parting surface. On this basis, based on the computer simulation technology, Procast casting molding software was used to simulate the ductile iron cross-casting process to optimize the cross-head casting process. Designed to make full use of ductile iron eutectic expansion and self-feeding riser, making the crosshead surface quality and internal defects are improved, and to a great extent to improve the crosshead casting efficiency.
