Abstract

PURPOSE:To increase the number of rolled stocks in the same rolling cycle and to improve the rolling efficiency by making work roll shift positions of plural stands different from each other in respective stands, shifting the work rolls in the axial direction in cycles, and preventing high spots of a rolled stock. CONSTITUTION:For a hot finishing rolling mill 10 having plural stands #3-#5 whose work rolls are shiftable in the axial direction, roll moving positions of the work rolls 1, 1 of the plural stands #3-#5 are made to be different from each other and the work rolls 1, 1 are periodically moved back and forth at the positions, so that a sheet passage position on the roll in respective stands #3-#5 is automatically changed. Therefore, eccentric wear or local wear of the rolls are hardly generated, so that irregular profiles caused by the above wears are prevented from generation and the number of rolled stocks by the same roll is drastically increased.
