鞍钢焊管厂生产的镀锌焊管,经过镀锌、水洗之后,约有80％发生弯曲,这是一个多年没有解决的老大难问题。去年全国第一次质量月活动之后,检查员王胜江、万传宣、朱振英等同志,在生产工人支持下,经过长时间的观察、试验,摸索出了不同规格的镀管浸在水洗槽过程中的最佳水温控制制度,基本上解决了镀管弯曲问题。 The galvanized welded pipe produced by Anshan Iron and Steel Pipe Plant has been bent by about 80% after being galvanized and washed. This is a chronic problem that has not been solved for many years. After the first mass month of activity in China last year, inspectors Wang Shengjiang, Wan Chuanxuan and Zhu Zhenying and other comrades, after long hours of observation and experiment, explored the immersion of plating pipes of different specifications in the washing tank The best water temperature control system, basically solved the problem of bending pipe.
