摘　　要：南钢在3 500 mm炉卷轧机上成功开发了(5～15)mm×3 200 mm宽薄规格Q345E钢板,其性能与板型均符合标准要求,尤其是-40℃低温冲击性能良好。并对南钢提高Q345E钢板性能合格率的工艺控制过程进行了重点介绍。Nanjing Iron and Steel Co. Ltd. has successfully developed wide and thin Q345E steel plate with limit dimension of （ 5 ~ 15 ） mm thickness × 3 200 mm width, of which the properties and flatness all satisfy the standard re- quirements, i.e. , the good -40 ℃ impact properties. The article highlights the process control to improve the per- formance qualification rate of Q345E steel plate in Nanjing Iron and Steel Co. Ltd.
