Verfahren und Vorrichtung zur hydraulisch-elektrischen Spaltregelung

摘要

The invention relates to a method and device for regulating the width (h) of the gap between at least two rollers coupled in a roll mill. If the gap changes as a result of disturbances during the rolling process, the piston travel and the valve position are detected and corrected so that the gap returns to the predetermined width. The operator can modify this predetermined width during operation. The device for implementing this method is characterized in that a valve (10) is fitted on a roller (1) having one control loop for the valve (10), and one for the roller (1).
