PURPOSE:To highly efficiently obtain a product superior in quality by performing rolling work in the width direction while feeding a long size material continuously to a rolling mill which consists of a cage-type roll supporting device and screw-down mechanism which is arranged on a concaved roll. CONSTITUTION:The rolling mill is made by arranging the concaved rolling roll 6 on one surface of a metal plate 1 so as to put the roll axis at approximately right angle to the advancing direction of the metal plate 1 and, on the opposite surface, arranging a roll supporting device 8 with the rotary shaft 7 parallel to the advancing direction of the metal plate 1 and arranging a group 10 of rolls with plural work rolls 9 on the outer periphery of the supporting device 8. The metal plate 1 is continuously traveled while adding coiling tension toward an opposite deflector roll 12 through a deflector roll 11 from a teed reel on one side of this rolling mill. The concaved rolling roll 6 is revolved together with the metal plate 1 and the group 10 of rolls is continuously revolved in one direction while applying rolling pressure on the metal plate 1. |
