Abstract: The invention relates to a method for producing a metal strip from a cast by rolling in which method the technique of a profiled rolling in combination with a strip rolling is used. The material for the metal strip is first cast by using a casting technique to produce a cast profile having the center part thicker than the lateral parts and the cast profile is in an essentially continuous manner conducted into a rolling mill where during the at least two-staged profiled rolling the cast profile is divided into two symmetrical segments and maintained as two equal segments. These segments are spread into the lateral regions of the material to be rolled into a flattened profile which is as an object for at least one-staged strip rolling so that the spread ratios between the center part dimension of the cast profile and the width of the strip of greater than 2.8:1 are achieved.

Abstract: The invention relates to a coil to be used in transverse flux induction heating of an object in the form of a metal strip or another elongate metal workpiece. The coil contains at least one pair of loops of conductors, which are non-symmetrically positioned to each other and the conductors overlap each other so that the inductor has double conductors across the object to be heated and a single conductor parallel to the object to be heated at the edges. The heating effect is prevented alone in the conductors by dividing the induced current for the conductors to two equal branches each having the same width as the original current and the combined heating effect in the branches is only half of the heating effect before branching.
