Abstract

Viene descritto un forno ad induzione perfezionato capace di riscaldare, in continuo ed in modo omogeneo, un prodotto piano di siderurgia, in particolare una bramma sottile proveniente da un impianto di colata continua, a monte delle operazioni finali di laminazione durante la produzione di nastri sottili di acciaio. Un forno di questo tipo a causa del piccolo spessore del prodotto da riscaldare dovrà presentare dimensioni ridotte delle bobine nel senso di avanzamento del nastro. Per evitare che in tali condizioni il rendimento diminuisca e si abbia un forte flusso disperso, con conseguenti gravi inconvenienti, la presente invenzione prevede un concentratone di flusso costituito da due pacchi lamellari continui aventi sezione sostanzialmente a forma di C che avvolgono superiormente ed inferiormente la bobina stessa per tutta la sua lunghezza lasciando libero soltanto il passaggio del prodotto da riscaldare all'interno della bobina.
