Abstract

An arrangement for a metal making process for detecting cracks along a strip of a metallic material moving in relation to the arrangement. The arrangement includes a coil arrangement fixedly arranged during crack inspection, having: a first winding portion extending in a first direction for inducing a first current in the first direction; a second winding portion extending in a second direction for inducing a second current in the second direction, the first direction and the second direction intersecting each other; a first receiver coil arranged to detect a magnetic field generated by the first current; and a second receiver coil arranged to detect a magnetic field generated by the second current, the magnetic field generated by the first current and the magnetic field generated by the second current providing a measure of whether a crack is present in the portion of the strip.
