  • Patent number: 4590984
    Abstract: A continuous casting installation has a dummy bar which is designed such that its connection with a strand can be broken by moving the dummy bar and the strand relative to one another in a direction transverse to the longitudinal axis of the strand. A straightening roll for the strand is movable in this direction between a raised position and a lowered position. A support roll is mounted in the region of the straightening roll and is pivotable between an elevated position and a depressed position clear of the casting path. In operation, the connection between the dummy bar and the strand is positioned between the straightening roll and the support roll. The straightening roll is in its raised position and is located above the strand while the support roll is in its elevated position and supports the dummy bar. The straightening roll is now lowered to straighten the strand thereby simultaneously breaking the connection between the dummy bar and the strand.

  • Patent number: 4518074
    Abstract: Hot, elongated metallic products are delivered to a horizontal roller table and then transferred to one side of the latter transverse to the longitudinal dimensions of the products. The transfer arrangement for the products includes several pairs of I-beams which stretch from one side of the roller table to the other and are upwardly inclined in the direction of transfer. The I-beams of each pair are spaced from one another, and a wheeled carriage is located in the gap between the I-beams of each pair. The wheels of the carriages are situated between the flanges of the respective I-beams. The carriages are aligned with one another in the longitudinal direction of the products and are driven in synchronism. This permits each product in the path of the carriages to be engaged by all of the carriages simultaneously. As the carriages travel in the transfer direction, the carriages sequentially lift the products from the roller table along a direction which is inclined to the horizontal.

  • Patent number: 4291748
    Abstract: A continuous casting machine for billets and blooms has a curved mold which is followed by a curved cooling zone and a straightener. A dummy bar for the casting machine has a length at least equal to the distance between the mold and the straightener. The dummy bar has a rigid portion and a flexible portion which are pivotally connected with one another. The rigid portion, which is curved and has a radius equal to the casting radius, includes a dummy bar head. The flexible portion is made up essentially of pivotally connected, curved links having radii equal to the casting radius. The flexible portion is designed such that it can assume radii equal to or less than the casting radius. When the dummy bar is in position for casting, the flexible portion assumes the casting radius and the dummy bar conforms to the curvature of the casting machine.

  • Patent number: 4257472
    Abstract: An apparatus for the continuous casting of hollow metal shapes includes a cooled, open-ended mold having a cooled mandrel positioned centrally of the mold cavity. The inner surface of the mold and outer surface of the mandrel together define a casting space. Molten metal is teemed into this space and solidifies adjacent the inner surface of the mold and the outer surface of the mandrel. In this manner, a body consisting of a molten mass confined between a pair of solidified skins is formed. The body is continuously withdrawn from the mold thereby generating a continuous strand which is hollow due to the presence of the mandrel in the mold. The outer surface of the strand is sprayed with coolant outside of the mold so that the molten mass within the strand solidifies progressively. The mandrel is provided with a passage which opens to the hollow center of the strand and a finely divided solid such as sand is fed into the center of the strand via this passage.

  • Patent number: 4237960
    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.

  • Patent number: 4235280
    Abstract: A continuous casting installation has a curved secondary cooling zone in which a partially solidified, continuously cast strand originally having a generally vertical orientation is turned towards the horizontal while being cooled. Spray nozzles are provided for spraying the upper and lower surfaces of the strand, as well as the sides of the strand, with cooling fluid during passage of the strand through the curved cooling zone. The spray nozzles for cooling the sides of the strand have slot-like openings which curve in the same direction as the curved cooling zone. These spray nozzles thus produce curved spray patterns. This makes it possible to reduce the number of spray nozzles required to cool the strand in the curved cooling zone thereby simplifying spray nozzle alignment problems. Furthermore, by appropriate selection of the radius of curvature of the slot-like openings, the spray nozzles for the sides of the strand may be positioned farther away from the strand than previously.

  • Patent number: 4146078
    Abstract: An apparatus for continuous horizontal casting has a vessel for holding the molten metal to be cast. The vessel has an opening in its side which is arranged so that a stream of molten metal issuing therefrom enters a horizontal path. The stream is maintained in a molten state in the upstream end portion of the path and is cooled in an adjacent downstream portion of the path. A mechanism is provided for continuously drawing the strand formed from the stream of molten metal along the path. During the initial stages of solidification, the strand consists of a thin shell of solidified metal surrounding a molten core. The strand tends to sag here and an arrangement is provided for counteracting the weight of the strand. This arrangement includes a connected pair of electrical contacts one of which is immersed in the body of molten metal and the other of which contacts the strand. The arrangement further includes magnets which generate a horizontal magnetic field extending normal to the axis of the strand.
