摘　　要：我厂生产的S195柴油机。年产已达20万台,随着机械工业产品向优质、高效、低能耗方向发展,对柴油机铸件的质量要求日趋严格,(如表面质量、尺寸精度、壁厚偏差等)。我厂S195柴油机机体型芯一直采用合脂砂制芯。工人劳动强度大,制芯生产环节多,(经烘干、并合、修正等工序),芯子废品率高,尺寸波动大而影响铸件精度。随着产量日益增加,车间型心烘干炉的负荷已饱和,常出现型芯烘不透使铸件产生气孔、针孔等缺陷。为了解决S195机体铸件的产量和质量问题。This paper deals with a series of problems of the shell core technique, that is applied to the casting process in mass production of the cylinder block of S195 diesel engine. It includes the shell box design, preparation of core sand, the determination of process parameters for core making, as well as the solutions for problems concerned in productive application etc, Meanwhile. some advantages brought by the shell core technique is also introduced.
