Abstract

L'invenzione concerne un procedimento, un dispositivo ed un prodotto-base per la produzione di billette per laminatoi a caldo.Viene proposto come obiettivo il compito di consentire l'utilizzo di billette possibilmente lunghe in un laminatoio a caldo, senza che per questo si rendano necessari forni di riscaldo corrispondentemente lunghi.Secondo l'invenzione, da tubi ottenuti per colata vengono tagliate billette a sviluppo elicoidale, che vengono avviate al processo di laminazione. (Fig. 1)The invention relates to a process, a device and a basic product for the production of billets for hot rolling mills. The aim of the task is to allow the use of possibly long billets in a hot rolling mill, without thereby require correspondingly long heating furnaces. According to the invention, helically developed billets are cut from pipes obtained by casting, which are sent to the rolling process. (Fig. 1)
