Casting apparatus and tubular mould for the continuous casting of thin-walled iron tubes

摘要

a track (6) comprises a thick cylindrical body (7), which is surrounded by an envelope of cooling (15) close to the casting pool (2), and in contact with it in a plane (p).the body (7) is extended in the opening (4) by a head casting composite annular lip (17) having a thin, inner (22) whose inner face is the body (7), and a ring (24) fitted between the refractory material body and the orifice lip, casting.the lip (hot) (22) connected to the body (7) in the plane (p), is that the ring (24) is also in the plan, and the flow of heat from the discharge orifice (fi) casting shell faces the cooling ring.
