- a furnace for heating the strip to a temperature near the melting point of a molten metal,
- at least one horizontally disposed shallow vessel containing a body of the molten metal,
- means for delivering make-up metal to the vessel,
- means for moving the strip through the furnace and transversely past one side of the vessel,
- a stabilizing roller positioned below the vessel for guiding the strip past the side of the vessel, and
- a jet nozzle positioned above the vessel and spaced from and transversely with the strip for controlling the thickness of the molten metal on the strip,
- the vessel including a shell having an upper surface and an inside surface, a refractory lining the inside surface, a spirally shaped coil for inductively heating the molten metal by magnetic flux, means for concentrating the magnetic flux and a departure lip mounted on the upper surface of the vessel,
- the induction coil being positioned below the refractory lining and the concentrating means being positioned below the induction coil,
- the induction coil and the concentrating means underlying the body of molten metal.
- 2. The coating line of claim 1 including a plurality of vessels.
- 3. The coating line of claim 2 wherein one surface of the strip passes adjacent to the side of one of the vessels and the other surface of the strip passes adjacent to the side of another of the vessels.
- 4. The coating line of claim 2 wherein one of the vessels contains a molten metal having a first composition and another of the vessels contains a molten metal having a second composition.
- 5. The coating line of claim 1 wherein the depth of the molten metal in the vessel is >20 mm.
