Title (EN) METHOD OF CONTROLLING DRAWING IN HORIZONTAL CONTINUOUS CASTING
(FR) PROCEDE DE REGULATION DE L'ETIRAGE PENDANT UNE ETAPE DE COULEE CONTINUE HORIZONTALE
Abstract:
(EN) A method of controlling drawing of a cast piece in horizontal continuous casting, in which drawing is controlled in accordance with an inwardly curved passage to keep the acceleration low at the start of the drawing and to increase it gradually in the drawing process for the purpose of reducing the number of bubbles appearing on the surface layer of the cast piece by sucking the ambient air into the mold when drawing the cast piece.
(FR) Procédé de régulation de l'étirage d'une pièce coulée pendant une étape de coulée continue horizontale, consistant à réguler l'étirage en fonction d'un passage courbe à l'intérieur, de manière à maintenir l'accélération à un niveau faible au début de l'étirage et à l'augmenter graduellement au cours de l'étirage, dans le but de réduire le nombre de bulles qui se forment sur la couche de surface de la pièce coulée à la suite de l'aspiration de l'air ambiant dans le moule lors de l'étirage de la pièce.
