Abstract

PURPOSE: To efficiently, simply manufacture a thin steel sheet, by adjusting the roll-bending amount in a prescribed latter rolling stand, in order to control the sheet crown ratio to a prescribed value.
CONSTITUTION: In a continuous hot finishing plant provided with ≥6 rolling stands, a small diameter work roll is employed in the latter 3W4 rolling stands; then, this small diameter work roll is operated by a roll bender to obtain a hot rolled steel sheet having ≥0.1 sheet crown ratio. In order to secure the rigidity of the small diameter work roll, a six-high rolling mill provided with an intermediate roll between a backup roll and the work roll is the most suitable. By the present constitution, the steel sheet having a greatly irregular thickness distribution along the breadth is manufactured by use of a substantially flat roll.
