    摘要: A feed system is provided for conveying molten metal to a thin section caster having mold surfaces moving exclusively in the direction of casting. The feed system has a passage of circular cross section adjacent to one end thereof for receiving molten metal and a rectangular cross section at the delivery end thereof adjacent to the caster. The feed system is designed for supplying molten metal to the caster at low pressure for "closed-pool" type caster operation. The point of highest elevation in the metal flow passage of the feed system is on the upper surface of a transition portion where the cross section changes from circular to rectangular adjacent to the nozzle. The level or height of the high point above the centerline of the nozzle exit is selected so as to be less than the pressure of the metal measured in inches at the nozzle exit. This feature enables the maintenance of positive pressure in the metal within the feed system so that ingress of air into the metal is prevented.

    摘要: A method of introducing molten metal, especially steel into a rectangular, open-ended continuous casting mold. The method is especially suitable for the continuous casting of high quality steel blooms and billets. The molten metal is introduced beneath the surface of a pool of molten metal contained in the mold from a submerged pouring nozzle as four fixed streams oriented with respect to the mold walls so as to produce a circulatory flow of molten metal around the perimeter of the mold.
