摘要
研究了采用消失模制备流体设备钢铸件工艺,主要包括模具制作、涂料配制及涂敷、浇注系统设计等内容;通过观察表面质量、内部缺陷和增碳量,分析了选用不同密度的造型材料对铸件的影响;证实了采用消失模铸造该铸件的可行性。通过试验研究比较,确定消失模铸造该流体零件最终模样密度为0.025g/cm3,采用锆英石为耐火骨料的涂料比较适合铸造该零件;在铸造过程中负压控制要求较高,尽量维持在0.03MPa左右。采用消失模铸造该流体零件,表面质量比较光滑,内部无明显缺陷,增碳量在要求范围以内。
In this paper, we had studied on lost foam casting process for hydro-hardware. It mainly included model making,dope confacting and daubing,casting system designing and etc. we had also analyzed that the different density of model material affected the casting which based on observing the surface, interior disfigurement and carbon increment. It is confirmed that the lost foam casting process was feasible for hydro-hardware casting.
