介绍了1 100 mm四辊单机架平整机湿平整工艺调整过程及改造内容。通过优选平整液,优化平整压力、平整速度,控制平整液残留、钢卷延伸率和工作辊粗糙度,实现了由干平整模式变为干/湿平整双模式。湿平整模式可实现批量生产MR-2/3/4、SPCC-T4BA、DC03/4/5等多钢种和高硬度、低粗糙度镀锡基板和普冷产品的需求。但因平整液残留导致带钢表面产生斑迹缺陷,仍是湿平整工艺今后攻关方向。

This paper introduces the adjustment process and transformation content of the wet leveling process of 1 100 mm four roll single frame leveler.By optimizing the leveling fluid,leveling pressure and speed,controlling the leveling fluid residue,coil elongation and work roll roughness,the dry leveling mode to dry/wet dual leveling mode is realized.The wet leveling mode can meet the requirements of mass production of MR-2/3/4,SPCC-T4 BA,DC03/4/5 and other steel grades,tinned substrates with high hardness and lowroughness and common cold products.However,the spot defect on the strip surface caused by the residue of leveling fluid is still the key research direction of wet leveling process in the future.
