Method for inductive heating of workpiece e.g. metal sheet, involves setting smallest distance between inductor and to-be-heated area arranged opposite to inductor, not exceeding specific value

摘要

The method involves heating workpiece by surface inductor. The smallest distance between the inductor and to-be-heated area arranged opposite to inductor is set not exceeding 10 mm. The surface inductor has induction coil arranged in a plane arranged parallel to the work area, so that the minimum distance vertical to plane and work area is measured.
