Abstract
An induction coil, preferably for an induction heater, comprises a working coil, an outer casing and an inner lead-through channel for the workpieces, such as rods or tubes, which are to be treated in the induction coil. The region of the outer casing closest to the working coil consists of a layer of a rubber-elastic compound outside which is arranged a concrete casing. Using a two-part outer casing of this kind avoids the use of asbestos which is increasingly suspect because of its health hazard.
