1、攀枝花学院PanzhihuaUniversity铸造工艺课程设计说明书设计题目：球墨铸铁连杆铸造工艺设计姓名：xxxxx院系：材料工程学院专业：材料成型及控制工程学号：xxxxxxx指导老师：xxx时间：xxxxx攀枝花学院本科课程设计摘要摘要首先，根据提供的零件图获取零件的技术要求、材料组成、结构特点、生产条件、生产批量及性能要求。然后，对零件结构的铸造工艺性进行分析，找出可能存在的结构问题提出改进措施或者预防缺陷的措施：根据零件的结构特点、技术要求、生产批量、生产条件选择铸造和造型方法。由零件的结构特点提出多种浇注和分型方案，综合对比分析，选择最为理想的

2、浇注位置及分型面。再次根据铸造工艺方案和零件的特点，选用适宜的工艺参数，设计铸件的浇注系统并绘制铸造工艺图。关键词：球墨铸铁，铸造工艺，浇注系统，工艺参数攀枝花学院本科课程设计目录目录摘要·······································································Ⅰ第1章绪论································································11.1课程设计的意义····································
