Definitions

  • the invention relates to a continuous casting plant for casting strands of liquid Metal, in particular of liquid steel material, and in particular of the type Casting plant with attached rolling mill, with a ladle over one the casting platform on rails movable carriage, with a distributor trough, the one Having pouring tube, and arranged on the carriage lifting device for the Adjustment of the pouring tube at pouring height in the continuous casting mold.
  • Distribution gutter cars are known (EP 0 940 205 A1).
  • the appropriately equipped Distributor gutters go on multi-line systems and more recently Composite casting back. It is known to provide two distributor door carriages.
  • the casting speed can be lowered and the distributor trough becomes inside changed from, for example, 4 to 6 minutes.
  • This change time is not at all continuous casting process. So the conditions are at Single-strand casting equipment significantly different.
  • a single-strand caster on which are cast compared to slab cross-sections relatively thin strand thicknesses, is due to the faster cooling, a lowering of the casting speed not possible.
  • the strand is solidified depending on the thickness in about 1-1.5 minutes.
  • One Composite casting can not take place in such cases. At this time could However, no Verteilerrinnen-change take place.
  • the invention is based on the object, the workflows on the casting platform to change when changing the tundish by little effort, u.a. making the crane handling easier and at the same time the distribution trolley adapt.
  • the stated object is achieved in that only a single Distribution gutter carriage is used, that this is designed as a manipulator is that on a supporting frame connected to the support frame a lifting and lowerable guide block is provided on the symmetrical in both directions Hanging means provided for each one-sided suspended distribution trough and that the guide block height adjustable together with at least one distributor trough is.
  • the advantage is the use of only one distributor trough wagon for casting processes that do not allow composite casting.
  • the manipulator shortens the way to the heating, because it worked in two directions can be. This relieves crane operation. The crane only drives the Distributor channels from the heating station to the workshop and back again.

This will increase the load capacity for gross weights the distribution channel up to 70 t and more guaranteed.
  • suspension axes with corresponding retaining claws on the distributor trough ensures a leveling to a selected position of the distributor trough, wherein it is advantageous that at the lower end of each lever a support surface for Counter support surfaces is arranged on the distribution channels.
  • An accurate, largely vertical guide for the height adjustment of distribution trough and pouring tube is further achieved in that on the support frame on both sides vertical guide posts are attached and that the guide block from the Suspension axles and the longitudinal struts or transverse struts and other frame parts by means of respectively arranged in the direction of travel guide roller pairs lifting and lowered is guided.

  • the location of the tundish i. by hanging the distribution channel in suspension axes scored position, and allow by the location of the suspension axis Furthermore, that the hinged distributor trough against the support frame in pairs arranged load cells is supported. This results in very accurate measurement results to the current weight of the distributor trough remaining Melt achieved.
  • the movement of the distributor trough during operation can still be improved be made by the suspended distribution channel for the weighing against the Friction-increasing transverse forces by means of coupling rods and rotatable guide rollers is supported.
  • Operation on the casting floor can be further simplified by the fact that the Distribution trolley from a left or right heating position to the casting position is movable over the continuous casting mold.
  • Another embodiment provides that the SEN heating means for the pouring tube are arranged on the manipulator. Therefore, the pouring tube can still until shortly before Recording of the casting operation to be heated or kept warm.
