针对大型铸造不锈钢泵壳砂型铸造工艺开展研究,对铸件材质及结构特点进行分析,结合Pro CAST软件对铸件充型及凝固过程的模拟结果对铸造工艺进行设计与改进。并通过试制,获得了铸件轮廓清晰,无缩松、缩孔缺陷的优良产品。
Aiming at casting process of large-scale cast stainless steel pump casing sand, the casting material and structural characteristics were analyzed. The casting process was designed and improved by Pro CAST software simulation of casting filling and solidification process. And through trial production, access to the casting outline clear, no shrinkage, shrinkage defects of the fine products.
