Definitions

  • the invention relates to a method and a device for oscillating a mold in a continuous casting installation, wherein a compensating mass assigned to the mold and adapted to the mold weight is oscillated in the opposite direction to the mold.
  • molds are oscillated, with a harmonic oscillation movement generally being selected. It is further customary to set the average mold lowering speed about 10-30% above the average pull-out speed of the strand. As the casting speed increases, the mean speed of the oscillation movement of the mold also increases.
  • a mold is known (DT-PS 2'036'266) which is oscillated by means of a crank mechanism via a handlebar, an air cylinder being provided to balance the weight of the oscillating mold.
  • DT-PS 2'036'266 is oscillated by means of a crank mechanism via a handlebar, an air cylinder being provided to balance the weight of the oscillating mold.
  • the invention has for its object to provide a method and an apparatus which allows casting with higher casting speeds and with correspondingly higher oscillation speeds or which allows casting with higher oscillation frequencies without the occurrence of harmful vibrations on the mold which negatively influence the continuous casting.
  • this object is achieved in that the acceleration forces of the mold be compensated for by the acceleration forces of the balancing mass at a common support point.
  • the acceleration forces from the oscillation movement are canceled before being introduced into the machine frame.
  • no vibrations occur even at high frequencies and high speeds of the oscillation movement.
  • this enables higher casting speeds to be run with proportionally increased oscillation frequencies and thus to increase the performance of the system.
  • oscillation frequencies over 100 and with billets and small bloom blocks, over 200 can be used without disturbing vibrations.
  • the center of gravity of the balancing mass can essentially be moved on the straight extension of the center of gravity of the oscillating mold.
  • the weight of the balancing mass can be chosen to be the same size as the weight of the oscillating machine part, consisting of the mold, the mold table, etc. According to an additional feature of the invention, the balancing mass can also be significantly smaller than the mold mass. To achieve this, it is recommended to use the balancing mass according to the equation m.
  • a A - m K. A K 0, where A A is the length of the lever arm of the balancing mass m and A K is the length of the lever arm of the mold mass m K.
  • the oscillation device is characterized in that the balancing mass has a drive which runs in the opposite direction to the oscillating movement of the mold element is provided and that the drive elements of the mold and the opposing balancing mass are assigned to a common support point.
  • a particularly advantageous arrangement of the opposing drive elements of the mold and the balancing mass can, according to a further characteristic, be achieved if the drive element for the mold and the driving element for the balancing mass are articulated on a short common crankshaft. Such an arrangement requires only a small starting torque.
  • a smooth running of the oscillation movement and a small drive power of the engine can be achieved if the crankshaft is provided with a flywheel.
  • the invention proposes to provide a gear drive or a chain drive between the drive motor and the crankshaft.
  • the invention sees an alternative solution if the mold and the countermass are arranged coaxially on one each hydraulic drive are articulated.
  • a further increase in design freedom with regard to the arrangement of the balancing mass can be achieved if the balancing mass is divided into several synchronously driven partial masses.
  • an arc mold 1 is articulated on the machine frame 3 by means of short steering levers, which result in a curved guide 2.
  • An oscillation drive 5 is connected to a short crankshaft 10 via chain wheels 4, 7 and a chain 6.
  • a drive element designed as a crank 11 for the mold 1 and a further drive element designed as a crank 12 for a balancing mass 14 that is matched to the mold weight.
  • These oppositely arranged cranks 11 and 12 are articulated via connecting rods 15 and 16 on the mold 1 and on the balancing mass 14, respectively.
  • the acceleration forces of the mold 1 and the balancing mass 14 acting on the two cranks 11, 12 are compensated in the crankshaft 10, which is fastened to a common support point 18 siert.
  • the leveling compound 14 is guided in a straight line along a guide 19.
  • the sprocket 7 connected to the crankshaft 10 is designed as a flywheel in order to achieve a uniform oscillation movement and to reduce the power required for the oscillation drive.
  • the balancing mass 14 is divided into partial masses driven synchronously on both sides of the mold. If desired, it could be further subdivided.
  • the lever arms of the cranks 11 and 12 are of the same size and the two compensating masses 14 arranged on both sides of the mold 1 are together as heavy as the parts of the oscillating mold group.
  • the weight of the balancing mass 14 can thus be changed, in particular reduced, within the framework of the equation mentioned.
  • Fig. 3 is a straight mold 34 and a compensation mass 35 articulated to a coaxially arranged hydraulic drive 36 or 37.
  • a carrier 39 is provided as a common support point.
  • a counter-rotating movement of the drive elements is ensured by means of a hydraulic control unit 40.
  • the two hydraulic supply and discharge lines 50, 50a and 51, 51a are each pressurized or depressurized synchronously.
  • the acceleration forces of the mold 34 are only compensated by the acceleration forces of the balancing mass 35 in this example at the common support point.
  • Guides 41 for the oscillation movement of the mold 34 and guides 42 for the balancing mass 35 are straight.
  • a gear drive 45 is provided between a drive motor 44 and the crankshaft 10.
  • the mold 1 and the balancing mass 14 have curved guides 4 and 47 for the oscillatory movement.
  • the method and the device according to the invention can preferably be used on continuous steel casting plants for billet, bloom and slab molds.
