Abstract
Strip material is fed to a reduction rolling mill by a steering device in the form of a pinch roll stand comprising pinch rolls to which strip gripping forces are applied by hydraulic cylinder units located at the ends of the pinch rolls. A reduction mill is similarly provided with a pair of hydraulic cylinder units which are independently operable to vary the pressure applied by the reduction rolls across the strip. Sensors sense the position of the strip at a first location in advance of the pinch rolls and a second location in advance of the rolling mill. This output of sensors is fed to a controller which controls operation of both sets of hydraulic cylinder units to steer the strip.
