压缩机十字头铸造工艺的优化仿真

Simulation and Optimization of Casting Process for Compressor Crosshead

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。

The casting process for compressor crosshead of ductile cast iron was analyzed, and the suitable pouring gate position and parting surface were chosen. The casting forming process of the crosshead was simulated by Procast software and the casting process was optimized. Finally, the self-feeding riser which makes full use of nodular cast iron eutectic expansion effect was designed to improve the crosshead surface quality and internal defects, and improve the casting efficiency of the crosshead.
