Abstract
A method for determining if a stretch of casting line includes the closing position of the liquid cone of a continuously cast metal product, where there is provided a casting line including an ingot mold containing the liquid metal and in which a meniscus is defined, one or more soft reduction roll devices, cylinders for actuating the one or more soft reduction devices, at least two oscillation application areas, the oscillation application areas being arranged in the one or more soft reduction roll devices. The oscillation being achieved by the rolls of the one or more soft reduction devices through the actuating cylinders. The method includes the following stages: a) applying an oscillation along the casting line to the cast product through at least two application areas in sequence; b) detecting the oscillating frequency of the meniscus level in the ingot mold; c) comparing the oscillating frequency of the meniscus level in the ingot mold with the oscillating frequency of the at least two areas of application.
