Abstract

A method for detecting an at least partly bulging portion of an elongated material produced in a continuous casting machine in which the machine has a plurality of rollers arranged in two tracks converging towards each other to transport the material, with the rollers being divided into at least two roller portions each rotatably mounted in supporting members. The method involves measuring the radial load exerted by the material on each supporting member of the roller portions of a roller, comparing the radial load values of the supporting members arranged in the ends of roller portions facing away from each other with those of the supporting members arranged in the ends of the roller portions facing each other to ascertain a divergence, and establishing that an at least partly bulging portion of the material exists where the divergence exceeds a predetermined value.

Dependent claims

Method for detecting an at least partly bulging portion of an elongated material produced in a continuous casting machine, comprising:

transporting the elongated material between two tracks converging towards each other in the continuous casting machine, each track comprising a plurality of rollers arranged substantially perpendicular to longitudinal extensions of the tracks, at least some of the rollers being divided into at least two axially adjacent roller portions, with each end of each roller portion being rotatably mounted in a supporting member;
measuring a radial load exerted by the material on each supporting member of the roller portions of at least one of the rollers;
comparing the radial loads of the supporting members at the ends of two adjacent roller portions facing away from each other with the radial loads of the supporting members at the ends of the two adjacent roller portions facing each other;
and
determining that an at least partly bulging portion exists in the elongated material when a divergence between the radial loads of the supporting members arranged in the ends of the two adjacent roller portions facing away from each other and the supporting members arranged in the ends of the two adjacent roller portions facing each other exceeds a predetermined value.
