针对砂型铸造工艺生产的喷淋泵壳体铸件在生产过程中出现的缩孔、缩松等缺陷,运用Any Casting软件对该铸件凝固过程进行模拟,结合铸件低碳马氏体不锈钢材料的铸造特点和结构的特殊性,分析缺陷的形成原因,通过工艺改进,消除了缩孔缩松缺陷,有效地解决了企业生产过程中的难题,获得了满意的铸件。 Aiming at the defects such as shrinkage cavity and shrinkage during the production process of the spray pump shell castings produced by the sand casting process, the casting solidification process was simulated by Any Casting software. Combined with the casting characteristics of low carbon martensitic stainless steel castings And the structure of the particularity of the reasons for the analysis of defects, through process improvement, eliminating shrinkage defects, effectively solve the problems in the production process, access to a satisfactory castings.
