阀体类锻件工艺改进及质量控制

Process Improvement and Quality Control of Valve Body Forgings

主要介绍了阀体类锻件产品的特点,并统计分析了以往发生的质量问题,发现执行工艺不严格和工装设计不合理是引起质量问题的主要原因。按PDCA循环进行工艺改进和质量控制,通过实施前后的效果对比,得到严格执行工艺,持续改进和细化作业指导书以提高产品质量的结论。

This paper introduced the characteristics of the forging products of valves, and analysed the issues of quality. The main causes of quality problems was found that the process was not executed strictly and it is not appropriate in die design. Process improvement and quality control were carried out by PDCA cycle. Compared with previous effect,the quality was improved by strictly executing process, persistent improvement and drafting operating instructions in detail.
