Beschreibung
Zusammenfassung:	The invention discloses a plate shape control method for cold rolling limit width and thinness deep drawing steel. The method comprises the following steps of producing a plate blank; conveying the plate blank to a hot rolling process for heating; controlling a hot-rolled coil; adopting front-section laminar cooling for cooling, and inputting edge shielding; performing natural cooling, and naturally cooling a coiled hot-rolled steel plate to below 60 DEG C; executing an acid rolling process for uncoiling and continuous acid pickling; continuous annealing; performing micro-leveling, wherein the leveling elongation is 0.4-0.5%; manually adjusting roll bending amount, the inclination amount and the roll shifting amount, so that the wave shape of the steel plate does not exceed 5I-unit; and finely trimming, manually confirming the shape of the steel plate, and coiling to obtain a steel plate finished product. The thickness and width specifications of the cold-rolled finished steel plate manufactured by the method
