Abstract
A device for casting a metal in the pasty phase in a continuous casting mold comprises a vertical conduit disposed upstream of the mold and provided externally with cooling means a distributor member disposed substantially at the inlet of the conduit to deflect the metal flowing from a casting nozzle towards the inner surface of the vertical conduit which may be extended by a tubular element penetrating into the mold and an inlet section for the conduit at least the inner surface of which is formed by refractory material, the distributor member being disposed in the inlet section. The device may have an injector for injecting a gaseous agent into the vertical conduit below the distributor member, and a further device for causing the metal to rotate in the inlet section.
Claims19
A device for continuously casting a metal in the pasty phase in a continuous casting mold comprising:
- a casting nozzle having an outlet;
- a vertical conduit disposed upstream of the mold with respect to the direction of travel of the metal from the casting nozzle, said conduit having an inlet, an outlet, and an inner surface extending between said conduit inlet and outlet;
- said conduit comprising,
- an inlet section adjacent said inlet,
- an inner surface formed of refractory material on said inlet section, and
- a downstream section disposed downstream of said inlet section;
- cooling means for cooling said downstream section of said conduit externally of said inner surface thereof;
- a distributor member disposed in said inlet section of said conduit having a surface in closely spaced relationship to said nozzle outlet for receiving metal poured thereon from said nozzle outlet, said distributor surface extending transversely with respect to said conduit inlet section a sufficient distance for discharging the metal directly against said inner surface of said inlet section;
- and means for injecting a gaseous agent into said conduit at a position downstream of and adjacent to said distributor member for producing a gas pocket within said conduit for urging the metal against said inner surface of said conduit.
