3、认真编写说明书（不少于3000字）。3．工作计划（进程安排）熟悉设计题目，查阅资料，做准备工作1天确定铸造工艺方案1天工艺设计和工艺计算2天绘制铸件铸造工艺图1天确定铸件铸造工艺步骤2天编写设计说明书3天答辩1天4．主要参考资料《热加工工艺基础》、《工程材料及成形技术基础》、《机械设计手册》系主任审批意见：审批人签名：滑动轴承座铸造工艺设计摘要砂型铸造在机械制造业中占有非常重要的地位,不受质量、尺寸、材料种类及生产批量的限制。而用于装轴瓦的部分总称壳件，其上半部称为轴承盖，下半部称为滑动轴承座。本次对滑动轴承座进行设计。

4、滑动轴承座大多用铸铁制造，材料为HT200或ZG200～ZG400，承受载荷大的采用铸钢或钢板焊接结构。广泛应用于冶金，矿山，输送系统，环保设备等。滑动轴承座在铸造过程中有严格的技术要求。本文通过对滑动轴承座的研究，得出滑动轴承座的铸造工艺。关键词：砂型铸造，技术要求，铸造工艺目录摘要第1章绪论······························································11.1课程设计的意义··········································
