Abstract
An arrangement for measuring the thickness of a strip emerging from a rolling mill is provided with a thickness measuring device and at least one linear inductor. The linear inductor exerts a pulling force on the strip which flatens the strip in the vicinity of the measuring device. This permits a measuring beam from the measuring device to pass through the strip in a direction orthogonal to the surface of the strip. In some embodiments, a plurality of linear inductors may be provided on either side of the strip, and on either side of the measuring device. The frequency of operation of the linear inductors may be controlled by a converter, in response to the speed of the emerging strip.
