我们在连接环锻件质量攻关小组的基础上成立一个QC小组。两年多来,为连接环锻件争创优质产品,运用TQC方法,通过多方调查分析,找出影响质量的各种因素,抓住主要矛盾,积极采取措施,使连接环(Ф18×64开口式连接环)锻件质量得到提高,破断强度达到部颁C级标准(41t)。一、QC小组开晨的第一个PDCA循环1.问题的提出从造成次品率的各个因素来看,最主要的是危险断面缺肉,有时缺肉的达90%以上。缺肉大小、深度随多种因素变化而互不
We set up a QC team on the basis of the Quality Assurance Group for Connection Ring forgings. Over the past two years, we have been striving for high-quality products for connecting ring forgings and using TQC method to find out the various factors that affect quality through various investigation and analysis, seize the main contradictions and actively take measures to make the connecting ring (Ф18 × 64 open type Connecting ring) Forgings quality has been improved, breaking strength reached the ministerial C-class standard (41t). First, the QC team opened the morning of the first PDCA cycle 1. Issues raised From the various factors resulting in defective rate, the most important is the lack of dangerous sections of the meat, and sometimes lack of meat up to 90%. Lack of meat size, depth varies with a variety of factors without each other
