摘　　要：球墨铸铁轴承盖在试生产过程中废品率较高,缩松、夹渣类缺陷尤为突出。针对这些铸造缺陷进行了原因分析并提出了解决措施。经过生产验证,缩松、夹渣等铸造缺陷得到有效控制,铸件质量显著提高。The rejection rate was higher in the trial production of bearing cap,particularly the defects of shrinkage and slag inclusion. The reasons were analyzed and some measures were adopted to remove the defects. Through production verification,the casting defects such as shrinkage,slag inclusion were effectively controlled and the casting quality was enhanced significantly.
