<p>The gauge control of a rolling mill is dependent upon adjustment of the rolling load by a hydraulic operable device which is supplied with hydraulic fluid from an electro-hydraulic device. The device is supplied with a control signal of variable gain which represents the difference between (H+ΔH)/h and v/V where H + V represent the entry thickness and entry speed and h and v represent the exit thickness and the exit speed. The gain of the signal is adjusted so that the control signal is at a level just below that at which hydraulic saturation occurs.</p> |
