SYSTEM FOR APPLYING PILOT CONTROL TO THE ROLL GAP ADJUSTMENT OF A GAUGE-CONTROLLED COLD ROLLING STAND

摘要

A system of applying pilot control to the roll gap adjustment of a gauge-controlled cold rolling stand. Included in the system are a gauge measuring apparatus for determining the incoming strip thickness, a differential computer for detecting changes in the gauge of the rolled strip, and delay means for the control signal to allow for running time of a point on the strip between the gauge-measuring location and the roll gap. Also included in the control is an evaluation system which takes into account deformation resistance of the rolled stock and of the roll stand constants in determination of the manipulated variable required for adjusting the roll gap.
