Messeinrichtung zur Erfassung des Walzspaltes

摘要

The invention discloses a measuring device for determining the width of the rolling gap of a rolling mill, wherein variation of the spacing between two work rolls during rolling is detected by means of the correspondingly varying spacing of two roller holders urged into contact with the work rolls on opposite sides of the rolling gap, a stator winding being attached to the one roller holder and a displaceable core in the winding being attached to the other roller holder by means of a rod extending through the rolling gap. Electrical output signals obtained from the winding in consequence of relative displacement of the core may be used for keeping the rolling gap constant. The spacing between the roller holders may be adjustable to cover a range of rolling gap widths.
