Development of a Combined Shape and Gauge Control Scheme Based on Function Φ

Abstract:

Combined shape and gauge control is a hot issue in continuous hot plate and strip rolling field. Due to the coupled function of shape and gauge control in rolling process, mutual effects must be considered when shape control is carried out. Traditional shape and gauge control theories are of independent and the control systems are also separated, so it is difficult to ensure the quality of shape and gauge simultaneously. Based on the shape theory of shape and gauge control and function Φ derived from the load distribution method of Ichiro Imai , a combined shape and gauge control scheme was developed, which can adjust rolling regulations on-line according to the deviation of strip crown measured at the exit of the rolling mill. The method can ensure gauge precision while strip crown is adjusted and the purpose of combined shape and gauge control is reached.
