Definitions

  • the invention relates to a device for introducing a flexible starting strand into a continuous casting installation, in particular a steel slab continuous casting installation, with a transport carriage having a slide or roller track, with which the starting strand can be transported to an inlet part of the continuous casting installation, the transport carriage carrying a conveying device for the starting strand and the slide or roller track has an arcuate end part, on which a guide device is provided which supports the approach strand on opposite sides, advantageously on the outside and inside of the arc.
  • a trolley of the type described above is known for example from DE-OS 22 21 18-7. With these known transport carriages, the start-up strand is moved over the mold, threaded into the mold by means of conveyors located on the transport carriage, and then lowered through the mold into the strand guide located below. In this process, threading into the mold is a particular problem, since it is not possible, or only with great effort, to move the transport trolley exactly into the “threading position”.
  • Transport wagons of the type described in the introduction have a weight of more than 50 t, even if only a short start-up line is used, to which the weight of the start-up line itself comes.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a device of the type described in the introduction, with which it is possible to bring the starting strand into the correct threading position quickly and accurately and with little effort.
  • the guide means at the lower end of the arcuate end portion is disposed and in Fahrrich- of the transport carriage displaceable t ung.
  • the guide device has at least one stop roller which supports one side of the start-up strand and is mounted in a frame and on the opposite side of the frame has a pinch roller which is pivotably mounted against the stop roller, the frame being slidably mounted on the carriage. This ensures safe detection and play-free movement
  • the displacement path of the guide device is limited by means of a limit switch which is fixed in place on the continuous casting installation.
  • the guide device is provided with a funnel-shaped inlet part, the funnel-shaped inlet part expediently having a plate rigidly attached to the frame and a plate which can be pivoted together with the clamping roller.
  • FIG. 1 shows a side view (partly in section) of a transport carriage in a schematic illustration
  • FIG. 2 shows a view from below in the direction of arrow II in FIG. 1.
  • the braking of the trolley in the vicinity of the mold 4 is first carried out by a limit switch, not shown, which greatly reduces the speed of the car, then by a second limit switch, also not shown, which brings the car to a standstill within a closer area of the mold.
  • the stop 5 and buffer 6 are only a safety device if the limit switches fail.
  • a roller conveyor 8 is mounted for storing a starting strand 7, the rollers 9 of which are rotatably attached to brackets 10.
  • the roller conveyor 8 has an arcuate end part 11, which makes up about a quarter circle.
  • drive rollers 12 between which the starting strand 7 can be clamped, held and conveyed, are provided. The drive of this Drive rollers 12 is not shown in detail.
  • a guide device is provided, which is generally designated 13.
  • This guide device has a frame 16 which can be displaced in the longitudinal direction 14 of the carriage by means of a pressure medium cylinder 15. In order to enable the frame 16 to slide easily, it can be moved by means of rollers 17 in side members 18 arranged on the transport carriage 1.
  • a clamping roller 20 is provided, which is rotatably mounted on a lever 21, which lever on the frame 16 can be pivoted about an axis 22.
  • a further pressure medium cylinder 23 which is articulated on the frame 16 serves to pivot the lever.
  • Sheet metal plates 24 are provided at the front end of the frame above the two rollers and between the two rollers.
  • the lever 21 of the pivotally mounted pinch roller 20 has an upwardly extended extension 25, to which a sheet metal plate 26 is also attached.
  • the function of the device is as follows: First, the trolley runs against a limit switch, not shown, which greatly reduces the driving speed, then against a second limit switch, causing it to stop when its guide device 13 is approximately above the mold 4. Then, by actuating the pressure medium cylinder 23, the clamping roller 20 mounted on the lever 21 is moved to the opposing stop rollers 19, so that the starting strand 7 is gripped and held with its foot end 27 to be threaded into the mold 4. Then, by actuating the pressure medium cylinder 15, the frame 16 is displaced until the stop rollers 19 are brought into position exactly above the mold side wall 28 assigned to them. Then the starting strand 7 can be threaded into the mold by means of the drive rollers 12 and on be lowered.
  • both the carriage 1 and the guide device 13 are fixed in their position.
  • the displacement of the guide device 13 is expediently stopped by a limit switch 29 fixedly attached to the continuous casting installation, for example on the mold 4.
  • the limit switch system can function without contact (electrical, optical) or mechanically.
  • the transport trolley can serve to introduce the start-up strand not into the mold, but into a threading point of the strand guide below the mold.
  • the advantage of the device according to the invention can be seen in the fact that only relatively small masses have to be moved when centering the starting strand 7. These are only the guide device 13 and the foot end 27 of the starting line.
