<P>PROBLEM TO BE SOLVED: To improve temperature uniformity in a width direction of a strip. <P>SOLUTION: An electromagnetic induction heating device of a metal strip 4 moving in a specific direction has at least one electric coil 2 arranged opposite to at least one surface in a large surface of a strip, so that the metal strip 4 is heated by induction of a magnetic bundle in a lateral direction. Each coil is coupled with at least one magnetic circuit 6, and each circuit is split into a plurality of magnetic rods 8 independent from each other arranged in parallel to a moving direction of the strip. In the electromagnetic induction heating device of the metal strip, the magnetic circuit 6 is constituted by the plural magnetic rods 8 independent from each other, and the magnetic rods are moved by being separated from each other and approaching to each other in a manner that distribution of the magnetic bundle is continuously adapted to dimension unique to the strip, and therefore, the distribution is adapted to the width of the strip 4 to be heated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
