本文介绍大连钢厂钢丝磷化QC小组运用PDCA循环,不断调整,改进了磷化工艺,先后解决了磷化膜薄,溶液变色,沉渣过多和硼砂吸潮等问题,使磷化涂层质量逐步改善,模索出一套适合高强度弹簧钢丝拉拔的磷化工艺。由于采用了磷化处理,改善了润滑条件,从而提高了拉丝速度,发挥了设备效率,取得了较好的经济效果。 In this paper, Dalian Steel Mill steel wire phosphating QC team using PDCA cycle, and constantly adjust and improve the phosphating process, has solved the phosphate film thin, solution discoloration, excessive sediment and borax moisture absorption so that the quality of phosphate coating Gradually improved, modeled out a set of suitable for high-strength spring wire drawing phosphating process. As a result of phosphating treatment, improved lubrication conditions, thereby increasing the drawing speed, equipment efficiency has been achieved, and achieved good economic results.
