Strip rolling mill apparatus

摘要

A multistand tandem strip rolling mill and associated method wherein effective control of gauge and shape are provided. Shape monitoring sensors may be provided adjacent to a first mill stand and adjacent to a downstream mill stand in order to provide feedback-feedforward information regarding strip shape and gauge to controller units which when a predetermined shape has not been achieved issues a control signal to adjust the actuators. A computer preferably has stored information regarding the desired shape and gauge effects a comparison between the signals received from the shape and gauge sensors.Gauge sensors may be provided adjacent to the shape sensors. The mill stands preferably have roll bending cylinders positioned by roll bending system servo-valves which are actuated by signals from the controller.
