Method of rolling metal strip

摘要

Three or more work rolls are arranged substantially in line with each other so that the adjoining work rolls each form a roll pass between them. The work rolls are driven in such a way that the rolls closer to the exit end of the rolling mill stand rotate with increasingly greater peripheral speeds. Metal strip is continuously passed through each roll pass and is wound around part of the periphery of the work rolls disposed between the work rolls at both ends of the stand. Thus, the strip is rolled between each pair of the adjoining work rolls. The work rolls are also driven in such a way that at least in one of the pairs of the work rolls, the peripheral speed of the higher-speed work roll is greater than the speed with which the strip leaves the roll pass formed by the pair of work rolls.
