Abstract

PURPOSE:To prevent the concentration of the abrasion of rolls at specific parts and to increase a roll bending effect by providing journal boxes for roll bending and journal boxes for roll supporting separately. CONSTITUTION:While keeper plates 35, 36 are held engaged to the engaging parts 34 of arms 23, 24 by the operation of plate opening and closing cylinders 32, 33, work rolls 1, 2 are shifted freely axially by turning handles 28, 29. Since these rolls are connected by oil hydraulic cylinders 13, 14 for roll balancing by means of pins 11, 12 respectively between the journal boxes 7, 8 and 9, 10 mounted to the rolls 1, 2 axially immovably, it is possible to apply roll balancing load upon the rolls 1, 2 during tilting despite the inclination of the cylinders 13, 14 by the shifting operation.
