Abstract
An oscillating cooled mold assembly for the continuous, high-speed casting of metallic strands or rods, especially upcasting strands or rods of copper alloys such as brass, has a hollow die in fluid communication with a melt typically held in a casting furnace. A cooler body surrounds the die in a tight-fitting relationship to form a solidification front in the melt as it advances through the casting zone of the die. The strand or rod formed from the solidified melt is pulled through the die while the mold oscillates in a direction substantially parallel to the direction of travel of the rod.
Claims47
An apparatus for the continuous casting of metal rod comprising:
- a support structure for supporting an oscillating mold assembly;
- a vessel containing a metallic melt;
- an oscillating mold assembly including:
- (1) a fluid coolable mold asembly in communication with said metallic melt for the continuous formation of a cast rod from said melt,
- (2) a movable carriage assembly for supporting said mold assembly, said carriage assembly being constrained to move in the same and reverse direction as a rod being continuously cast,
- (3) means for oscillating said carriage assembly and thus oscillate the mold assembly in the same direction and in a reverse direction of a rod being cast, said means for oscillating said carriage assembly including at least one rail oriented in the same direction as the rod to be cast and at least one roller which engages said rail, said combination of at least one roller and at least one rail being the means by which said oscillating mold assembly is movably supported by said support structure, and,
- (4) a hydraulic cylinder having a piston with said hydraulic cylinder being supported by said support structure and said piston being connected to said carriage assembly so that movement of the piston is transmitted to the carriage assembly to cause the carriage assembly to oscillate along said at least one rail;
- means for drawing the metallic melt through said mold assembly to continuously produce a rod;
- and,
- means for delivering a coolant to said mold assembly while said mold assembly is oscillating.
