ABSTRACT:
An immersion nozzle includes an immersion zone inserted into a long-thin mold cavity of a mold. A discharge channel extends through the nozzle for discharging molten metal into the mold cavity. The discharge channel includes an inlet region, an outlet region including a portion passing through the immersion zone, and a pool-forming chamber between the inlet region and the outlet region at a location adjacent the immersion zone. The portion of the outlet region of the discharge channel that extends through the immersion zone is widened and has a configuration to approximate the cross-sectional configuration of the mold cavity. The outlet region has, extending from the chamber in a direction of material flow, a configure approximately corresponding to the configuration of the portion of the outlet region through the immersion zone.
