FILIERE TUBULAIRE POUR LA COULEE CONTINUE D'UN TUBE AVEC PAROI MINCE DE FONTE

摘要

The die (6) comprises a thick cylindrical body (7) which is surrounded by a cooling jacket (15) clamped against the pouring basin (2) and in contact with the latter in a plane (P). The body (7) is extended in the casting orifice (4) by a composite head (17) comprising a thin inner annular lip (22), whereof the inner surface extends that of the body (7) and a ring (24) of refractory material fitted between the lip, the body and the casting orifice. The (hot) lip (22) is connected to the body (7) in the plane (P), so that the ring (24) rejoins it also in this plane and that the flow of heat (f1) passing from the casting orifice to the cooling jacket must skirt around this ring.
