    • A dip forming apparatus for continuously forming a cast rod includes a furnace for holding molten metal, and a crucible having an open top and a bottom wall. The crucible has a core wire-passing region vertically extending therethrough. The crucible has a hole formed through the bottom wall. A passage connects the furnaces to the core wire-passing region. A device is provided for keeping the molten metal in the furnace at a predetermined level so as to flow the molten metal from the furnace to the core wire-passing region through the passage. A partition wall is disposed in the passage and has a throttling orifice of a predetermined size formed therethrough so as to allow the molten metal to pass therethrough to limit the flow of the molten metal from the furnace to the core wire-passing region. A drive device moves the core wire upwardly at a preselected speed through the hole and the core wire-passing region, so that the molten metal in the core wire-passing region accretes on the core wire to form the cast rod.
    • 用于连续地形成铸棒的浸渍成形装置包括用于保持熔融金属的熔炉和具有开口顶壁和底壁的坩埚。 坩埚具有垂直延伸穿过其中的芯线通过区域。 坩埚具有通过底壁形成的孔。 通道将炉子连接到芯线通过区域。 提供一种用于将炉中的熔融金属保持在预定水平的装置,以使熔融金属从熔炉流过芯线通过区域。 分隔壁设置在通道中并且具有通过其形成的预定尺寸的节流孔,以允许熔融金属通过,从而限制熔融金属从熔炉流到芯线通过区域。 驱动装置通过孔和芯线通过区域以预选速度向上移动芯线,使得芯线通过区域中的熔融金属在芯线上增加以形成铸棒。
