Abstract: An apparatus and related process for immersing a moving wire within a both of molten metal is applicable to wire forming processes. A flat-bottomed tray has at one end a nozzle for dispersing molten metal across the floor of the tray, from a first end to a second end, in a sheetlike flow. The nozzle preferably includes a slot-like opening, and is associated with a chamber for receiving a supply of pressurized molten metal for discharge through the slot. The metal is discharged with sufficient velocity to create a hydraulic jump or standing wave, whereby the crest of the wave is elevated above the tray end walls. Within the wave, molten metal experiences a turbulent flow in a direction against the travel of the wire array. The wire array passes through the wave, thereby experiencing immersion while being drawn through the apparatus in a straight path without substantial declination.
