摘要
针对1002011-90D缸体铸件小批生产时,出现的水套芯子折断、砂眼、渗漏和气孔等缺陷,分析了产生的原因,采取了相应的措施,并跟踪落实。将有效的工艺措施及时固化,较好的解决了90D缸体上述缺陷,使产品的成品率得到了明显提高,取得了较好的经济效益。
The defects of water jacket core break, sand inclusion, leakage and blowhole of 1002011-90D block casting with small batch production were analyzed, and some measures were adopted. The process was traced and carried out, the defects of 90D block casting were solved by the effect process. The yield of the product has been significantly improved, good economic results were achieved.
