[0025] The method and device for adjusting the transverse warpage of the strip steel of the present invention will be described in detail with the accompanying drawings. among them, figure 1 It is a schematic diagram of the roll shape of the pinch roll 1 with the upper roll having positive crown and the lower roll having no crown. As shown in the figure, the lower roller adopts a cylindrical shape with no convexity to improve the life of the lower roller. At the same time, it is advantageous for the strip to pass through the pinch roller 1 and enter the pinch roller 3 during the coiling process.
[0026] figure 2 It is an explanatory diagram of the roll shape of the pinch roll 3 in which the upper roll has a positive crown and the lower roll has a negative crown. The load roll gap of this pinch roller is parabolic, and the opening direction of the parabola is opposite to the opening direction of the transverse warpage of the strip. The pinch roller 3 has a strong ability to adju...
