Abstract
Un processo per produrre billette e blumi direttamente da colata continua, così che questi prodotti lunghi siano già in condizioni di passare al laminatoio finitore per la produzione di acciai di alta ed altissima qualità, comprende una fase di deformazione a cuore liquido della sezione di colata con riduzione della sezione stessa a parità di perimetro. Ciò avviene nella zona compresa tra il punto (S), ultimo punto di liquido surriscaldato sull'asse di colata, ed il punto di completa solidificazione della colata stessa o termine della lunghezza metallurgica. Preferibilmente la suddetta operazione di deformazione viene effettuata fra il 10% e l'80% della concentrazione dei grani solidi nella massa fluida.L'apparecchiatura per realizzare tale processo comprende essenzialmente mezzi atti ad avvicinare almeno uno dei settori componenti la via a rulli nel percorso di colata continua a quello contrapposto, in almeno un piano passante lungo l'asse di colata, in corrispondenza della suddetta zona di deformazione.
