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.

Abstract: In order to improve disassembly of the oscillation mechanism at a continuous casting installation, the continuous casting mold and the first support guide zone, and at the same time to obtain a support guide arrangement free of dislocation at the transition location, an upper section of the machine base frame and a support frame for the mold and the first zone of the support guide arrangement are at least partially overlappingly arranged. The underside of the frames are supported upon a foundation which is common to such frames. The upper section or portion of the machine base frame at its upper end region and the support frame for the continuous casting mold are movably supported in the direction of travel of the continuously cast strand at a common support location.

Abstract: The invention relates to a method and apparatus for obtaining an ingot wherein elastic oscillations are directed on metal being crystallized over a broad frequency range and at high intensity in the form of powerful pulses generated by a high-voltage spark discharge in liquid. One form of the apparatus of the invention comprises a discharge chamber filled with liquid in contact with a mould or with melt. The discharge chamber is provided with a system of electrodes connected to a pulse current generator. Upon feeding high-voltage current pulses to the electrodes, high pressure, impulse flows, cavitation and surge waves are built-up in the liquid resulting in the appearance of elastic oscillations acting on the molten metal.

Abstract: An installation for casting molten metal into a continuous strand from an oscillatory mold comprises a mold discharge guide rack including an assembly of guide elements for the continuous metal strand and two side supports for the guide elements. A mechanism for imparting oscillations to the mold includes a guide bar and a control lever operatively associated with the guide bar. Two fluidtight housings each affixed to a respective one of the side supports encloses the guide bar which is mounted in the housing on guide rollers assuring lateral and transverse guidance of the guide bar therein.

Abstract: In a continuous casting plant comprising a fixed frame, a table, and a mold supported by said table, a mold rocking device comprising at least one first bell-crank lever keyed at its apex to a first shaft rotatably journalled by said fixed frame, said first lever being pivotably connected at one end to one side of said table; at least one second bell-crank lever keyed at its apex to a second shaft, parallel to said first shaft, rotatably journalled by said fixed frame, said second lever being connected, in a slidable and pivotable manner, at one end to the side of said table opposite to the one to which the said first lever is pivotably connected; the second end of said second bell-crank lever being connected to a rocking device; and means for transmitting the said rocking movement from said second bell-crank lever to the second end of said first bell-crank lever.

Abstract: A detector for monitoring the bath level in an oscillatory continuous casting mold oscillates with the latter. The detector generates signals indicative of the bath level and a control unit interprets the signals and initiates adjustment of the bath level if this is outside of prescribed limits. Since the detector oscillates with the mold, and thus relative to the bath, the distance between the detector and the surface of the bath changes continuously even if the bath level remains constant. Inasmuch as the detector cannot distinguish between its own movement and that of the bath level, the oscillation of the detector results in the supply of misinformation to the control unit. In order to correct for the oscillation of the detector, a limit switch is connected with the detector or the control unit and is arranged to be closed by the oscillator at a predetermined point of its stroke. Thus, the detector will always be at the same position when the limit switch is closed.

Abstract: A mold assembly for continuous casting has a plurality of open-ended molds. The mold assembly further has a cooling member which is common to all of the molds and cooperates with each mold to define one or more cooling passages therewith. The cooling member, which is provided with one or more pairs of coolant inlet and outlet bores, is in the form of a cooling jacket or in the form of a back-up plate depending upon whether the molds are tube molds or plate molds. The mold assembly is rotatably mounted on a mold table having a casting location at which a mold is positioned during a casting operation. A coolant supply and coolant discharge conduit are arranged in the mold table adjacent the casting location. In operation, one of the molds of the assembly is positioned at the casting location with the remaining molds being in standby positions. At least one pair of the coolant inlet and outlet bores in the cooling member is aligned with the coolant supply and discharge conduits in the mold table.

Abstract: Reciprocating apparatus is provided for a strand casting mold which is simplified and less expensive to produce. This is achieved by mounting the mold supports in resilient bearings, and reducing the length of the drive train from the drive motor to the rocker gear. Moreover, provision is made in the drive train of the invention for accommodating expansion and contraction caused by extreme temperature variations at the operating site.

Abstract: In a lifting-table-guide arrangement having two oppositely arranged vertical guide elements provided on each of two opposing sides of a mould lifting-table of a continuous casting plant, one of the two oppositely arranged vertical guide elements provided on each of two opposing sides is supported by two rollers mounted one above the other in a lifting-table-guide stand and the other one of the two oppositely arranged vertical guide elements provided on each of two opposing sides is supported by a single counter bearing. The counter bearing is designed as a bearing for a rocker having two rollers arranged at a distance from each other, which rollers support the other one of the two oppositely arranged vertical guide elements.

Abstract: Disclosed is an apparatus for multi-strand continuous casting wherein a plurality of strands may be spaced apart from each other by a distance only dependent upon the dimensions of a copper plate and water-cooling jacket of a mold because a multi-strand mold oscillation mechanism may be installed independently of the spacing between the adjacent strands and the amplitude of oscillation of each mold may be suitably adjusted depending upon the casting conditions but independently of each other. Cast products emerging from the molds are withdrawn through a multi-strand roll apron or bending unit, a multi-strand casting bow, a multi-strand straightener and a multi-strand table by a multi-strand-pinch-roll stand consisting of a plurality of coaxial multi-pinch-roller assemblies, the individual pinch rollers in each assembly being driven independently of each other.

Abstract: Strain reduction or reversal technique for continuous casting of a metal billet element wherein there is provided an axial mold wall which is oscillatable, a plug element in the axial wall which may be solid in the sense that it closes one end of the mold or which may be of a type in which molten metal may flow therethrough into the mold, one of said elements being oscillatable with respect to the axial wall in a manner to relieve strain on metal newly freezing to the axial wall during oscillation of the axial wall.
