Abstract
Horizontal supporting rolls disposed at a lateral side of the work rolls support the work rolls in the direction of travel of the rolled material, and horizontal back-up rolls disposed at a lateral side of the horizontal supporting rolls back-up the horizontal supporting rolls. Frames rotatably hold the horizontal supporting rolls and the horizontal back-up rolls at both axial ends of these rolls, and a first driving mechanism causes a movement of the frames in the direction of travel of the material to be rolled and to impart to the work rolls desired pressing force acting in the direction of travel of the rolled material. A second driving mechanism restrains the position of the frames thus setting the work rolls at predetermined offset positions, provided on the face of the housing confronting the holding means and adapted to guide the movement of the holding member in the direction of travel of the rolled material. With this arrangement, it is possible to prevent any horizontal deflection of the work roll thus affording a highly precise crown and shape control on the rolled product, while facilitating the setting of the work rolls at a designated offset position, as well as replacement of the work rolls.
