Definitions

  • the invention relates to a transport device for the continuous supply of a continuous casting plant with molten metal by means of casting cars and pouring ladles which can be deposited therein.
  • the molten steel is first transported in ladles from the converters to the continuous casting plants, which is usually the purpose of the existing overhead crane.
  • a ladle turret which either has a rigid support arm that can be pivoted around the fixed rotating column and two receptacles or is designed with two support arms that can be pivoted individually from one another around a rotating column, each with a pan holder, is always poured from the pan of the support arm rotated over the mold.
  • the other support arm is in an out-of-operation position, where when the Content of the pouring pan is poured, a filled pan is suspended and swung over the mold in exchange for the empty pan.
  • the indoor crane then clears the arm with the empty ladle.
  • the ladles are fed with respect to the ladle change as described above for a ladle turret, with the only difference that the transport is not carried out on a circular swivel path, but on a linear path.
  • the casting operation is always maintained via intermediate containers as a buffer station.
  • the invention is based on the object of being able to carry out a fully continuous continuous casting operation even when the space available in a casting hall is the realization of conventional supply systems, e.g. B. a ladle turret or a double caster, do not allow. In other words, it should be possible to have a fully continuous casting even with the most compact possible and with a minimal space requirement.
  • This object is achieved according to the invention in that there is only one casting trolley designed to accommodate a single ladle, which can be moved from the casting position into an out-of-operation position, in which the emptied ladle, with such a change in its height relative to the pouring wagon, can be taken over from a support supporting the pouring ladle on the bottom that the pouring wagon, which is open on its side facing the support, can be returned empty to the pouring position.
  • the path for the single pouring wagon need only comprise a little more than the diameter of a ladle, which means that the space required for the transport device according to the invention is extremely small.
  • the change in the height of the emptied ladle relative to the pouring wagon in the inoperative position can take place in that the support taking over the emptied ladle can be raised and lowered, for example consists of a hydraulic lifting cylinder which, in order to enlarge its wing area, has a number of star-shaped arrangement Boom has.
  • this lifting cylinder With this lifting cylinder, the empty ladle can be easily lifted out of the top open receptacles on the ladle for the trunnions of the ladle.
  • the support can also be immovable if the casting car itself is provided with a lifting and lowering device for a suspended ladle.
  • a lifting and lowering device is desirable for moving a ladle in the pouring position; it needs to be designed to place 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 trunnion of the ladle can be lowered to such an extent that the ladle can return empty to the casting position.
  • the half-open receptacles on the ladle for the ladle's trunnions can be pivoted about 90 ° about a pivot axis, which runs below the center axis of the trunnion. Since with such a swiveling movement the half-open receptacles reach a swiveling position in which they are open to the side, the pouring wagon can immediately move back into the pouring position after the immovable ladle has been taken over by the immovable support.
  • 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, designated overall by 1, on the casting platform of a single-strand or multi-strand casting installation.
  • the actual strand guide frame with 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 wagon 2 has an outlet opening for the molten steel in the intermediate areas, which are only indicated schematically. container 9 can deliver.
  • the pouring wagon 2 with the ladle 8 is located 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 during the entire duration of the sequence casting while the intermediate container is switched on. release the desired amount of steel using 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 attack on the bottom of the ladle 8a, the ladle out of the open-top receptacles 15 of the casting carriage 4.
  • the pouring wagon is thus free again and travels to the pouring position, so that the filled pouring ladle held ready by the crane with its hanging loops 11 can now be placed in the receptacle 15 of the pouring wagon.
  • the indoor crane then takes over the empty ladle 8a raised by the lifting cylinder 13 and transports it away.
