The invention discloses a method for improving the quality of cold-rolled strip products, and particularly relates to the method for reducing the pinchers of a cold-rolled strip coil. The technical scheme is that: the method comprises the following steps of: when the transverse thickness difference of the cold-rolled strip coil is more than or equal to 15 mu m, exchanging the head and the tail of strip steel for re-coiling, increasing the setting of a cooling fan by 8 to 10 percent when the re-coiled strip steel is fed into a continuous annealing furnace for annealing, and reducing the setting of the coiling tension of the annealed strip steel at a continuous annealing furnace outlet section by 10 to 11 percent; when the transverse thickness difference of the cold-rolled strip coil is less than 15 mu m, reducing the setting of the tension at a continuous annealing furnace process section by 7 to 15 percent, and reducing the setting of the coiling tension of the annealed strip steel at an outlet section by 8 to 15 percent; and when a coiling length is more than 500m, eliminating the coiling tension at the outlet section, manually and transversely moving a coiling position by 1 to 2mm, performing the re-coiling, controlling a re-coiling acceleration gradient not to be more than a process speed, and performing the next acceleration after the stable running of 10 seconds.
