Abstract
Cette invention concerne un dispositif, qui comprend au moins un transformateur (1) ayant un rapport entre la bobine primaire (N1) et la bobine secondaire (N2) supérieur à un et comprenant une unité de commande (9) servant à commander la synchronisation et l'amplitude du courant primaire, ce dispositif étant utilisé pour chauffer une pièce de métal (4) devant être soumise à une opération de formage ultérieure. Un générateur de courant continu homopolaire peut également être utilisé comme source de courant pour la préparation par chauffage par courant de la pièce en vue de l'opération de formage. Des opérations de chauffage, de formage et de refroidissement ultérieures de la pièce de métal sont effectuées de façon contrôlée par une unité de synchronisation centrale. Ce procédé peut être appliqué au forgeage en vrac de métal, au formage de tôles et au formage par soufflage de tubes à chaud.
