Abstract: Induction furnace, method for operating, control program, and control device for an inducation furnace for heating planar rolled stock material made of metal. The rolled stock passes through the induction furnace in a longitudinal direction and extends transversely thereto from a first to a second rolled stock edge. The induction furnace has a plurality of module pairs which, viewed in the longitudinal direction, follow one another sequentially and each have a first and a second induction module. The induction modules, as viewed in the transverse direction, are positioned at a respective initial position, so that the first induction modules are arranged offset towards the first rolled stock edge and the second induction modules are arranged offset towards the second rolled stock edge. Induction modules are supplied with electrical power via respective power supply devices. A respective electrical target variable is defined for each induction module.
