<p>PURPOSE:To make shape control surer and quicker by providing a shape detector on the outlet side of work rolls and changing the viscosity of the lubricating oil to be supplied between a rolling material and the work rolls in the transverse direction of the rolls. CONSTITUTION:The thickness of the rolling material 3 on the outlet side can be controlled by the change in the film thickness of the lubricating oil to be supplied to the work rolls 1 and the material 3. The shape detector 4 is provided on the outlet side of the rolls 1 and many nozzles 7 for supplying the lubricating oil having a prescribed viscosity between the material 3 and the rolls 1 are disposed in the longitudinal direction of the rolls 1. A calculator 5 calculates the required viscosity distribution of the lubricating oil and inputs a signal to a control device 6 when the inadequate shape of the material 3 is detected by the detector 4. The device 6 makes the necessary correction of the lubricating oil distribution, by which the shape straightening of the material 3 is executed. The shape control of the material 3 is thus quickly and surely executed.</p> |
