Definitions

  • the device for transporting ladles to a continuous caster thus generally consists of a wagon that can be moved on the hut floor, an indoor crane and a ladle wagon or ladle turret arranged at the level of the casting platform.
  • This facility for transporting the liquid steel to the continuous caster is expensive because high halls with expensive hall cranes are necessary.
  • the invention is therefore based on the object of making the device for transporting ladles cheaper, in order thereby to make continuous casting more economical.
  • this object is achieved in that the lifting device for the ladles is arranged directly on the support member and is movable with it, and in that a travel path of the means of transport to the ladle changing station is provided.
  • the solution according to the invention makes it possible to omit an expensive indoor crane, which would have to be equipped with a correspondingly high track above a ladle car or a rotating tower. It is also possible to build the hall correspondingly lower. Both measures can significantly reduce the cost of the facilities for transporting ladles and thus make the continuous casting of steel more economical.
  • the support member consists of a rotating tower having at least one support arm, which is attached directly to the support arm with a hoist, guide cables are guided over outer ends of the support arm and with Device for transporting ladles to a continuous caster
  • the invention relates to a device for transporting ladles to a continuous casting installation, consisting of a lifting device for lifting the ladles coming from the steelworks from a means of transport and for raising them to their casting position height and a support member that moves the ladle between a casting station and a ladle changing station.
  • a pouring jet protection for example a pouring tube
  • the raising and lowering of the pouring ladle during the pouring by means of the hoist is an additional advantage.
  • the lifting device cheaper, in certain cases it can be more economical if the two support arms of the rotating tower are connected to one another in a straight line and rigidly and the lifting device can be moved between the outer ends of the two support arms and each end of the support arms is equipped with a support device for a pan. With this device, a single hoist is sufficient for the two support arms of the rotating tower.
  • the support device for the pan is arranged so as to be pivotable about a vertical axis and support the support pins of the pan in the carrying position.
  • Another advantage of the ladle support device according to the invention is the lifting and replacement of emergency pans, overflow channels, etc., which are usually set up in the range of motion of the support member between the casting station and the ladle changing station.
  • a continuous steel caster for billets, blooms or slabs is often made as shown in Fig. 1.
  • the liquid steel coming from the steelworks is supplied in hall A, and the continuous casting machine 1 is located in hall B.
  • a mold 11 is arranged on a casting platform 3 below an intermediate vessel 13.
  • a roller strand guide is shown at 12.
  • the device for transporting ladles 2, 2 'from the steelworks to the ladle changing station 6 of the continuous casting installation consists of a carriage 20 which can be moved on the floor of a hut.
  • a ladle turret 33 is used as the supporting element.
  • This ladle turret 33 essentially consists of two support arms 31, 32 which are connected to one another and rotatable about a vertical axis 34.
  • One support arm 31 of the rotating tower 33 is located in the casting station 7 above the intermediate vessel 13 in hall B and the other support arm 32 in the ladle changing station 6 in hall A.
  • empty pans are exchanged for full pans.
  • each support arm 31, 32 is equipped with its own lifting gear, which consists, for example, of a winch 41 for a cable 42.
  • the cable 42 is guided over the deflection roller 35, which is placed at the extreme end of the support arm 31.
  • the pans 2, 2 ' are attached via suspension devices 45 in the form of support hooks.
  • the two winches 41 are equipped with separate control devices.
  • Protective shields 46 are attached to protect against thermal radiation. When the pans have reached their highest position, the hoists can be blocked.
  • the installation costs can be further reduced if only a single lifting device 43 is used, as is shown in a further embodiment in FIGS. 4 and 5.
  • the lifting device 43 is mounted on a movable carriage 40, which can move on rails 34 on the top of the straight and rigidly connected support arms 31 and 32 (FIG. 2).
  • the hoist 43 can thus move from the end of one support arm 31 or 32 to the end of the other support arm 32 or 31.
  • the support arms 31, 32 must be equipped with support devices 56 for each pan 2 in order to clear the lifting device 43.
  • Each support arm 31, 32 of the rotary tower is provided with fork-shaped recesses at its outer ends, as usual. Between these recesses, the support devices 56 for the pan are attached to two brackets 60.
  • brackets 60 can be rigidly attached.
  • the carriage 40 is moved to the extreme end of the support arm 31.
  • the pan 2 is then lifted so far that its support pins 21 are at a higher level than the support device 56 and then the carriage is moved until the support pins 21 are exactly above the support device 56 are located, whereupon the pan 2 can then be placed on this.
  • the bracket 60 can be arranged to be pivoted away about a vertical axis 61, as shown in FIG. 5.
  • the movable carriage is placed in such a way that the axis of the support pins 21 is located centrally above the support device 56.
  • the brackets 60 are in the pivoted-away position, which allows the trunnions 21 to pass through.
  • the pan is raised so far that yours
  • Support pins 21 lie a little above the support devices 56.
  • the brackets 60 are then pivoted into the support position below the support pins 21 so that they can be supported on the support devices 56.
