Definitions

  • the invention relates to a transport device for ladles for the continuous supply of a continuous casting plant with molten metal by means of a single, one-sided open pouring carriage, which can be moved between a non-operating position and a pouring position and is provided with open-top receptacles for the ladles brought up by means of a crane, wherein the casting car can be freed from the casting ladle by changing the height of a ladle relative to the receptacles of the casting car.
  • a casting trolley open to the casting position can be moved between an inoperative position and the casting position.
  • supports are arranged at the pouring position that hold the ladle in the pouring position.
  • the pouring wagon moves the ladle from the supports to hold it in the pouring position until it is emptied and then remove it.
  • Such a device has the advantage over the known ladle turret or the known double casting wagon that it takes up less space and requires less construction.
  • the device has the disadvantage that the ladle cannot be brought from the stationary supports to an emergency pan quickly enough in an emergency situation.
  • the installation also requires specially designed ladles, which can be supported at the same time by the supports of the supports and the casting carriage at the moment of transfer.
  • Another ladle transport device is known (US-A-3 877 612), in which a full ladle is kept on standby on a pouring wagon in an inoperative position next to a ladle held by the crane in the pouring position. This means constant use of the indoor crane.
  • the second ladle must therefore hang filled in the ladle during the entire pouring time of the first ladle. Apart from the increased safety risk in the operating area, the setting of a precisely defined melting temperature at the time of casting becomes problematic.
  • a ladle is provided on the bottom independently of the pouring wagon support that the support can be raised and lowered to change the height of a ladle picked up or received by the pouring wagon or - at immobile support - the casting car is provided with a lifting and lowering device for a suspended ladle, and that the casting car is open on its side facing the support.
  • the travel path for the single pouring wagon need only comprise a little more than the diameter of a ladle, which means that an extremely small space requirement is set for the transport device according to the invention.
  • the only requirement for a quick change of ladles is that when a drained ladle is removed, a filled ladle must be hanging from the crane above the pouring position in order to be able to quickly put this filled ladle on the empty returning pouring wagon.
  • the intermediate container is poured.
  • the height-adjustable support can advantageously be designed as a hydraulic lifting cylinder, which can have a plurality of arms arranged in a star shape in order to enlarge its wing.
  • a lifting and lowering device provided with an alternatively immovable support on the casting car may be desirable for moving a casting ladle in the casting position.
  • This device needs to be designed for setting down an emptied ladle on the support within the scope of the invention only with regard to the stroke so that after placing an emptied ladle on the support, the receptacles for the trunnions of the ladle can be lowered to such an extent that the pouring wagon is empty can return to the casting position.
  • the mode of operation of the transport device described so far can also be reversed by placing a filled ladle on the support, the hall crane then taking over the empty ladle from the pouring position, and the then free pouring trolley picking up the filled ladle from the prop, likewise with a relative movement the height between the ladle and the trolley is required to hang the filled ladle in the trolley.
  • FIG. 1 shows the arrangement of the ladle transport device, denoted overall by 1, on the casting platform of a single-strand or multi-strand casting installation.
  • the egg The usual strand guide structure with a mold is not shown.
  • the casting car transport device 1 consists of a movable casting car 2, which can be moved by means of wheels 3 on a carriageway 4 between a casting position 5 and an out-of-operation position 6.
  • the roadway 4 is at a certain height above the casting platform and rests on supports 7, the supports 7 being arranged in an area of the casting platform which is not required for the pure casting activity.
  • the carriageway 4 itself is cantilevered into the casting area, so that a ladle 8 set down in the casting car 2 can discharge the molten steel into the intermediate container 9, which is only schematically indicated, via an outlet opening.
  • the casting car 2 with the ladle 8 is on the carriageway 4 in the outermost driving position, delimited by stops 10, above the intermediate container.
  • the continuous caster is supplied with liquid steel from the ladles while the intermediate container is switched on for the entire duration of the sequence casting.
  • B. release the desired amount of steel by a stopper and slide control. If the content of the pouring ladle 8 is running low, the hall crane (not shown) creates a newly filled ladle and initially keeps it with the sling loops 11 in the crane harness in a position above the pouring position 5.
  • the supply of the system with steel fluid is maintained for a short time by the supply of the intermediate container 9.
  • the emptied ladle 8 is then quickly replaced by the new ladle hanging in the crane. Since the supply is carried out with only one pouring wagon 4, the wagon travels a short distance to the inoperative position 6 located directly next to or behind the pouring position, where the carriageway 4 is delimited by further stops 12.
  • the pouring wagon 4 with the empty ladle 8a stands centrally over a lifting cylinder 13 arranged below the carriageway. When the lifting cylinder 13 is acted upon, the piston of the cylinder extends and lifts with several arms 14 arranged in a star shape (FIG.
  • the indoor crane then takes over the empty ladle 8a raised by the lifting cylinder 13 and transports it away.
