<p><P>PROBLEM TO BE SOLVED: To provide a method of preventing winding deviation of a steel strip which can easily and adequately prevent winding deviation of a steel strip after cutting by a shear in winding the steel strip around a tension reel in a steel strip continuous processing line such as a continuous annealing line. <P>SOLUTION: A protruded roll 30A having flat parts respectively on a roll width center part and roll width end parts is used as pinch rolls 13, 23. A differenceΔR (=Rc-Re) between a radius (Rc) of the flat part 31 of the roll width center part of the protruded roll 30A and a radius (Re) of the flat part 32 of the roll width end part is made to be a value beyond a maximum value of a side edge part elongation amount h and a high spot value H of the steel strip 1. A width L (a length in a roll width direction) of the flat part 31 of the roll width center part is made to be a width which does not cross over a generation area of side edge part elongation of the steel strip having a minimum width passing through the pinch rolls 13, 23. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
