Système de chauffage par induction de produits métalliques, notamment des bandes, ô flux magnétique longitudinal, caractérisé en ce que l'inducteur (6 ) comporte entre ses spires, deux déflecteurs de champ magnétique (7, 7') dont la forme et la disposition sont choisies de façon qu'ils masquent les spires de l'inducteur au niveau des rives (2) de la bande (1).(figure 3) The invention concerns a heating system by induction of metal products, in particular metal strips with longitudinal magnetic flux, characterized in that the inductor ( 6 ) comprises between its coils, two magnetic field deflectors ( 7, 7' ) whereof the shape and arrangement are selected such that they mask the inductor coils at the edges ( 2 ) of the strip ( 1 ).
