ABSTRACT:
An inductive billet heating apparatus in an inductive heating furnace for billets of rectangular section uses a plurality of paired heater modules having a flat shape. The billets are fed by a plurality of paired roller elements and each heater module in each pair of heater modules is suspended from respective ones of the paired roller elements on opposite sides of the billet such that a substantially constant distance from the opposite surfaces of the billets to the respective heater modules is independent of the thickness and/or straightness of the billets. At least some of the heater modules may be mounted to be rotatable in a plane parallel to the respective surfaces of the billets. The heater modules may be series-connected in pairs and the paired heater modules either series-connected or parallel-connected in groups.
