Abstract
A device () for inductive heating of a workpiece () in a rolling mill, the device () including: a converter () for creating an alternating voltage, a capacitor bank () electrically connected to the converter (), and having a plurality of capacitors () connected in parallel, a working field (), in which an upper coil () and a lower coil () are arranged. The workpiece () is able to be passed between the coils () and is thereby inductively heated by cross-field heating. A housing () arranged next to, below or above the working field (). The converter () and capacitor bank () are arranged in the housing (). The coils () are each electrically connected to the capacitor bank () by a flexible cable (). The cable () is a coaxial cable (), with one phase of the alternating voltage applied to an inner conductor () and the other phase of the alternating voltage applied to an outer conductor () of the coaxial cable (). The cables () are cooled by a fluid, such as air or water ().
