Metallic filament is continuously cast by directing a stream of molten metal onto the quench surface of a rotating quench wheel. Expansion mechanisms disposed about the quench wheel and between the quench surface and quench wheel drive shaft allow unrestrained radial and lateral thermal growth of the hoop-like quench surface while maintaining concentricity of the quench surface with the shaft. Crowning or thermal bowing of the quench surface is minimized and a transverse cross-sectional uniformity of the cast filament is maintained.

Expandable quench surface

A casting wheel cooling apparatus and method for rapid quenching of molten metal is provided. The cooling apparatus provides a multiplicity of axial conduits around the periphery of the wheel, close to the chill surface. In operation, molten metal deposits on the chill surface of the rapidly rotating casting wheel. The molten metal cools and solidifies, transferring heat to the casting wheel. By flowing coolant, preferably water, through the conduits at a sufficient rate, the heat transfer is generally radial. The molten metal cools uniformly across its width and the resulting metallic strip has substantially uniform properties.

Forced-convection-cooled casting wheel

An apparatus is provided for planar flow casting of metal ribbon. The apparatus comprises a movable chill surface, a reservoir for holding molten metal and a slotted nozzle whose lips are located close to the chill surface. In operation, molten metal is forced through the nozzle onto the chill surface to form a melt puddle. Rapid cooling of the molten metal results in the formation of a continuous ribbon. The nozzles of this invention provide a planar bottom surface which includes the leading edge of the first lip and the side edges at the bottom of the lips and which is as close or closer to the chill surface than is any other point on the lips. The nozzle reduces air flow around the melt puddle and thereby improves ribbon uniformity.

Nozzle geometry for planar flow casting of metal ribbon

An apparatus is provided for planar flow casting of metal ribbon. The apparatus comprises a movable chill surface, a reservoir for holding molten metal and a slotted nozzle whose lips are located close to the chill surface. In operation, molten metal is forced through the nozzle onto the chill surface to form a melt puddle. Rapid cooling of the molten metal results in the formation of a continuous ribbon. Ribbon contour is controlled through the use of nozzle designs that provide reproducible configuration of the melt puddle and reduce turbulent air flow over the molten metal surface.

Contour control for planar flow casting of metal ribbon

An apparatus for providing 'long ends' on reels of wire is incorporated in a continuous wire spooler. In an illustrative embodiment, continuous spooling is achieved by alternately filling each of a pair of reels while the other, previously filled, reel is removed and replaced with an empty one. The reels are filled with the aid of a wire distributor which is periodically commuted between the two reel positions in order to guide wire from a source to the reel being filled. At each of the reel positions there is provided a reel-receiving arbor including a concentric dummy reel positioned to be axially aligned with and adjacent to a reel which is mounted on the arbor. A chain in a closed loop is movable in a plane perpendicular to the arbor. A portion of the loop is substantially aligned with a corresponding part of the perimeter of the aft flange of the dummy reel. As the chain moves around its track, a guide pin mounted on the chain intercepts wire positioned over the empty reel and moves the wire over the aft flange of the reel and the fore flange of the dummy. Thereafter, a cam striker mounted on the chain closes a relay as it moves along the chain path. The relay causes a throw pin, mounted proximate the arbor to engage the wire and move it into position for snagging. A snagger mounted to a rotatable snagger disc constituting the aft flange of the dummy reel engages the wire for winding onto the dummy reel. Thereafter a second guide pin mounted on the chain intercepts the wire from the distributor and moves it back over the fore flange of the dummy reel and the aft flange of the empty reel. The wire, which is to be spooled on the empty reel, is guided by a shield ring to mate with the empty reel in such a manner as to assure proper engagement therewith. Upon such engagement, a second cam striker on the chain closes a relay, thereby stopping the movement of the chain.
