Abstract

Procedimento per l'ottenimento a freddo di profili e/o barre (14) partendo da un laminatoio a caldo (11),detti profili e/o barre ( 14) essendo valutati dimensionalmente in relazione alla gamma dimensionale tipica dello specifico laminatoio (11) detti profili e/o barre (14) ponendosi nell'intorno delle dimensioni più piccole della detta gamma dimensionale tipica del detto specifico laminatoio (11) ed in quelle poste al di sotto di essa fino alle dimensioni minime di mercato, detto ottenimento prevedendo una fase di laminazione a caldo di un elemento unico (10) comprendente una pluralità di profili e/o barre (14), detti profili e/o barre (14) essendo di sezione simmetrica, asimmetrica o speciale, detto elemento unico (10) laminato a caldo venendo raffreddalo e poi sottoposto all'operazione di separazione (13) multipla a freddo per separare longitudinalmente i singoli profili e/o barre (14).
