Abstract

Il presente trovato si riferisce ad un procedimento e ad un gruppo di laminazione a caldo e a freddo di metalli ferrosi e non ferrosi per la produzione di una barra o vergella tonda da una barra o vergella tonda di maggiore diametro. Il procedimento consiste nell'introdurre una barra o vergella con profilo iniziale a sezione tonda in un gruppo laminante provvisto di cilindri di laminazione con profili definenti un passaggio tondo di diametro minore rispetto al diametro della barra o vergella in ingresso. A monte del gruppo laminante, la barra o vergella di maggiore diametro viene sottoposta all'azione di rulli folli con profili atti a deformare la barra o vergella di maggiore diametro secondo una conformazione determinante, in uscita dal gruppo laminante, una barra o vergella con sezione tonda di diametro minore.
