    摘要： Induction heating is used to heat a moving strip (4) of non-ferrous material by causing it to form a short-circuited loop acting as a secondary winding of a transformer (1), the loop passing pulleys (6, 9, 16). The lengths of material which are incoming and outgoing to and from the loop are on the inside and outside of the loop. For the strip on the inside of the loop to connect with the exterior without further contact with the loop, an insulating spacing member is located between the loop and that strip, preferably by maintaining that strip out of the plane of the loop.

    摘要： The wire is moved axially at a suitable speed by external means, such as for example the means for collecting the annealed wire, is passed around preferably idle pulleys so as to form in contact therewith closed loops or turns one flight of which is passed through a window in the toric core of a transformer which generates a magnetic flux by means of a feeding primary circuit. Said wire loops constitute, substantially, the secondary circuit of said transformer and are heated due to the Joule effect by the current induced by the electro-magnetic flux generated by said transformer. Since the secondary of said transformer is shortcircuited, said transformer needs very low electric voltages at the secondary in order to produce the power required for the treatment. A plurality of loops or turns of wire may be arranged in parallel to each other to reduce the electric voltage required for the thermal treatment of said wire, so as to achieve high working speeds without exceeding the voltage limits established by the present safety regulations. A suitable winding method permits to concentrate the heating electric power in the flight of wire extending between two successive pulleys and passing through the window in the core of the induction transformer. Means are described for maintaining the temperature in the pulleys substantially uniform, and other means are described for ensuring a suitable tractive force on the wire. The adjustment of the electric voltage in the primary circuit of the induction transformer permits the furnace to operate in combination with variable-speed wiredrawing machines, while a grounded stainless steel screen interposed between the primary and the secondary of said transformer, with no formation of turns, grants the safety to the operator. This solution may be used either with single-wire and multiple-wire systems, while the variation in the number of the turns of wire in series or in parallel permits the use of the same electric voltage for different wires moved at the same speed, thus reducing the electric power requirements.

    摘要： Four électrique amélioré à induction destiné à être utilisé dans le traitement thermique continu d'une longueur de bande de métal (10) recouverte d'une couche avançant, se déplaçant dans un passage sensiblement droit à travers le four (32), comprenant au moins une bobine chauffante (34, 36, 38, 40, 42 et 44) s'étendant tout autour du passage de la bande et en étroite relation par rapport aux surfaces opposées de la bande (10). Le four (32) est monté sur une glissière (54) permettant le mouvement transversal du passage de bande, et chaque bobine (34, 36, 40, 42 et 44) est pourvue de portes de communication amovibles (170) pour ouvrir et fermer les boucles continues par lesquelles, lorsque la bobine (34, 36, 38, 40, 42 et 44) n'est pas alimentée, les portes de communication (170) peuvent être désenclenchées pour ouvrir la bobine (34, 36, 38, 40, 42 et 44) et permettre de déplacer le four (32) le long de sa glissière (54), entre une position rétractée de non utilisation et une position de traitement thermique en ligne. Les bobines (34, 36, 38, 40, 42 et 44) sont supportées pour permettre un réglage transversal et angulaire afin d'aligner avec précision les bobines (34, 36, 38, 40, 42 et 44) avec la bande (10), grâce à quoi les surfaces opposées de la bande sont sensiblement équidistantes des bobines chauffantes (34, 36, 38, 40, 42 et 44) le long du passage à travers le four (32).

    摘要： Inductive heater for heating the edges of a longitudinally extending body with a flat cross-section, preferably of stabs, strips or sheets in connection with rolling processes. The inductive heater (1) is arranged to surround the outer parts of at least one edge of said body for heating this edge, and consists of one or more bent plane coils which are arranged so that the outermost parts of said edge will pass through a greater part of the coil than parts located further in towards the interior. Thus the outer edge of the body is stronger heated than parts located further in towards the interior of the body. With the help of the inductive heater a slab, strip or sheet immediately after continuous casting or a preceding hot rolling operation can be heated in order to prevent the occurrence of too low a temperature in these parts during a subsequent rolling operation.
