Roll for rolling mill and roll-shift type rolling mill |
摘要 |
A rolling mill includes a roll barrel having a straight region disposed at the middle thereof, sub-crown control regions disposed at both ends thereof, and main-crown control regions disposed between the straight region and the sub-crown control regions. The roll barrel has an outer surface having a bus bar which is a straight line inclined to a longitudinal axis of the roll barrel in the straight region, steep convex and concave curved shapes in the main-crown control regions, and gentle convex and concave curved shapes in the sub-crown control regions. The roll barrel has both ends having a diameter approximately equal to each other. The roll provides a large degree of freedom in designing curves to be applied to an outer surface of a roll barrel with the result that a larger crown control can be performed, and has a small number of factors for a vibration of a plate. The roll shift type rolling mill in accordance with the invention decreases an irregularity in plate thickness distribution at ends of a plate even when a plate having a width larger than specific maximum plate width is to be rolled.
