Method and devices for induction heating during the passage of a

The device for protecting the poles of an electromagnetic inductor comprises a heat exchanger formed by one or more co-planar metal tubes (6) designed to allow the circulation of a cooling fluid therein and of such an arrangement that there is at most one electrical junction between any two tubes or tube elements. The exchanger is fastened to a rigid electrically insulating support plate (5) coated with refractory concrete (10) and covers the entire polar surface as far as the cowls (3). The exchanger can be shaped in the form of a series of alternating hairpins or in the form of a spiral with one or more branches. The device serves especially for protecting the poles of inductors used for the induction heating of metal products.
