浅槽紊流推拉式酸洗技术研究及应用

Shallow Slot Turbulent Push-pull Pickling Technology Research and Application

介绍了冷轧厂浅槽紊流推拉式酸洗技术应用情况。分析了酸洗钢带表面发黑的原因和酸洗浓度、温度对酸洗效果的影响,通过控制工艺段酸槽的温度、浓度、漂洗水的PH值,提高烘干温度和吹边效果,消除了酸洗钢带表面发黑现象,提高了酸洗钢带表面质量。

Introduces the cold roiling plant of shallow slot turbulent Push-pull Pickling Technology application. Analyses the influence factors of concentration, temperature and acid pickling strip surface blackening of pickling effect, the temperature, concentration, rinse water control process acid tank pH value, improve the drying temperature and blowing edge effect, eliminates pickling surface blackening of steel phenomenon, improves the surface quality of pickling strip.
