摘　　要：利用DISA垂直造型线,从铸造工艺创新和制造过程管控两方面进行管理;设计了一种空调压缩机球铁曲轴的模具工艺,改进了球化包内衬的结构设计。结果表明,实现了快速浇注,延缓了球化剂的反应时间,将球化等级控制在1-3级、球化率≥80%、内在品质稳定的球铁曲轴大批量生产。Using the DISA vertical molding line, management from two aspects of foundry process innovation and manufacturing process control;The mould technology of ductile iron crankshaft for air conditioning compressor was designed, the structural design of spheroidized lining was improved. The results show that the rapid pouring is realized, the reaction time of nodular iron is delayed, and the nodular iron crankshaft with stable internal quality is mass produced with the nodular iron level controlled at level 1-3, nodular rate 80%.
