Plate rolling mill and plate rolling process

Eliminate the offset amount of the deviation of the work roll in the upper and lower and left and right rolling mill occurring during kiss roll tightening state and rolling the zero point adjustment work etc. before rolling, the thrust force occurring between the plate warpage or work roll-backup rolls an object of the present invention is to solve the problem of meandering or camber, etc. due to. Therefore, a pair of upper and lower work rolls driven by an electric motor, a pair of upper and lower rolls supporting the rolling reaction force applied to the working rolls in contact with the working roll for each of the upper and lower work rolls a plate rolling mill having a device and for loading an external force substantially horizontal direction, the direction of the horizontal direction external forces to the load to the work rolls, the horizontal component of the rolling reaction force applied to the working rolls by the rolling direction offset is the same direction as the force, horizontally the external force is loaded to the working rolls, a plate rolling using it and a plate rolling mill, characterized in that it is supported by the project blocks or work roll chock support members of the mill housing to provide a method.
