Method for controlling surface rolling lines of cold-rolled deep-drawing steel for outer plate

The invention relates to the technical field of metal material machining, in particular to a control method for surface rolling lines of cold-rolled deep-drawing steel for an outer plate. According to the control method, in the cold rolling deep drawing steel production process, the lubricating rolling technology, the roller period and pressing of the hot continuous rolling procedure, the roller period and surface roughness and pressing of the acid continuous rolling procedure, and the roller surface roughness, the peak value number, the roller diameter difference and the through plate leveling force of the continuous annealing procedure are controlled. The control method can improve the surface texture of the cold-rolled deep-drawing steel to obtain a target finished steel coil. 本发明涉及金属材料加工技术领域，具体涉及一种外板用冷轧深冲钢表面轧制纹的控制方法。所述控制方法在冷轧深冲钢生产过程中对热连轧工序的润滑轧制工艺、轧辊辊期及压下，酸连轧工序的轧辊辊期、表面粗糙度及压下，连续退火工序的轧辊表面粗糙度、峰值数、辊径差及通板平整力进行控制。本发明控制方法可改善冷轧深冲钢表面纹理，获得目标成品钢卷。
