Abstract
PURPOSE: To prevent the work roll from slipping in order to enable the strip of good surface condition to be rolled with a high draft percentage, by arranging tension rolls at a position opposite to inner work rolls, at rolling the strip with rolls driven at different circumferential speeds in a single-stand multipass continuous rolling mill.
CONSTITUTION: When the strip S is continuously rolled by a single-stand multipass cold rolling mill in which work rolls 11W14 are arranged between backup rolls 15, 16, the circumferential speeds V1WV4 of respective work rolls 11W14 are made different from each other so as to be V4>V3>V2>V1. Hereupon, tension rolls 17, 18 are arranged so as to face inner work rolls 12, 13, the strip S is wound around these tension rolls 17, 18, and its tension is adjusted by shifting the tension rolls 17, 18, using the roll holders 19, 20. Since the strip S is passed in an inclined position against the low speed work rolls 11, 12, 13 through the first pass I, the second pass II and the third pass III, the strip of uniform front and back surface condition can be rolled with a high draft percentage.
