摘　　要：文中介绍了1550 mm酸轧机组生产65Mn冷轧宽钢带的工艺.通过焊接工艺研究,改善了焊缝质量,解决了65Mn焊接性能差、易断带的技术难题;通过对酸洗工艺、压下制度、张力控制等冷轧工艺参数研究,实现了65Mn冷轧宽钢带稳定生产,产品厚度公差控制精度高,表面质量良好,完全符合技术标准要求,获得用户好评.The technology of producing 65 Mn cold rolled wide strip by 1 550 mmPL-TCM was introduced in this paper. Through the study of welding technology, the welding quality was improved, and the technical problems, including poor welding performance and broken-tendency belt of 65 Mn, were solved. Through the study on the rolling process parameters such as pickling technology, rolling reduction system, tension control,etc., the steady production of 65 Mn cold rolled wide strip was realized, the control precision of the product thickness tolerance was improved, and the surface quality was enhanced. Finally, it fully meets with the requirements of the technical standard and is highly praised by users.
