Abstract

Una gabbia calibratrice (10) per la lavorazione di barre laminate a caldo (17) comprende almeno una coppia di cilindri di laminazione (13) portati da guarniture (12) montate su di una intelaiatura di supporto (11). Detta gabbia comprende inoltre mezzi di potenza (14) capaci di precaricare a compressione il sistema di laminazione con un carico che è maggiore del massimo carico di lavoro.
