ABSTRACT:
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.
