<p>The tube which conveys molten steel in continuous casting from a distributor reservoir to the mould comprises a refractory lining (10) in a metal casing (1, 3) having ribs (5) and a refractory tube (12) the upper end of which is secured within the casing (1, 3), the lower end projecting below the casing and intended to be submerged below the metal surface in the mould. A side spout (6) is provided for insertion of a rod of metal alloying material into the flowing melt stream; the region of penetration of the spout through the lining (10) includes a vault formation (8) and relieved area (9) to minimise metal splashing and accumulation. <IMAGE></p> |
