半连轧厂轧板工段1700机组,实行全面质量管理以来,显著地提高了热轧带钢质量。从前年9月份开始,这个机组工人,在技术人员帮助下围绕着解决带钢厚薄不均的关键问题,进行了攻关。一年来,他们按照计划一实施-检查-总结步骤(即PDCA),经过三个循环,取得了如下成果: 1.1978年9月份,带钢整卷厚度合格率为88％,1979年9月份提高到99.88％。鉴于钢板厚薄不均的现象明显改善,长春汽车厂取消了钢板挑选队。 2.厚度大于4.5毫米的带钢,整卷厚度合格率为100％,其中,厚
Semi-continuous rolling mill section 1700 units, the implementation of total quality management has significantly improved the quality of hot-rolled strip. Starting from the previous year in September, the crew of the crew conducted a research project with the help of technicians around the key issues of uneven strip thickness. In the past year, they completed the following three cycles in accordance with the plan of an implementation-inspection-sum-up (PDCA). The following results were achieved: 1. In September 1978, the passing rate of strip thickness was 88% and in September 1979, 99.88%. In view of the obvious improvement of uneven steel thickness, Changchun Automobile Factory canceled the steel selection team. 2. Strip thickness greater than 4.5 mm, the entire thickness of the pass rate of 100%, of which, thick
