Definitions

  • the invention relates to a casting tube changer for a casting device for producing metallurgical products, according to the preamble of claim 1.
  • pouring tube is also to be understood to mean pouring nozzles which essentially fulfill the same function as the pouring tubes and differ from these mainly due to the different overall lengths.
  • Cast iron changer of the type mentioned are known to replace a worn casting pipe with a new, especially in casting devices for producing continuous casting without interrupting the operation of the casting plant. This is done by Move the new pouring tube into the casting position, taking along the worn pouring tube.
  • a changing device of this kind is in the EP 0 714 332 B1 revealed.
  • the casting tube changer does not contain any means for rapid closing of the pouring channel in emergencies, for example in the case of pouring pipe breaks or similar serious occurrences. This is in the view of the reliability of the system of disadvantage.
  • EP-A-723 829 discloses a shutter device by means of which a blind refractory plate can be manually displaced from a supply to a standby position by manual operation, and subsequently this dummy refractory plate can be slid below the pouring channel and close it. But even with this closure device is disadvantageous that this required manual operation time-consuming and may be dangerous for the operator under certain circumstances.
  • the invention has for its object to avoid this disadvantage and to provide a G confuserohrwechsler of the aforementioned type, which accomplished both the pipe replacement and an emergency closure of the casting channel with the simplest possible means.
  • the invention also provides that the dummy plate in the waiting position is held in normal operation above the displacement level of the casting tubes and in an emergency can be lowered automatically to the displacement plane of the casting tubes.
  • the latter can therefore also be used for the blank plate in an emergency. In this way, the structure of the changing device is simplified.
  • the actuator according to the invention consists of a guided in the direction of the casting tube slide and a transversely to the direction pivotally connected driver. As a result, the plane of action of the driver is automatically adjustable.
  • the blanking plate can be coupled to the driver by means of preferably hackenförmig formed suspension elements.
  • the blanking plate is preferably provided on both sides with a horizontal longitudinal groove and an obliquely lying to it guide groove, which cooperate with a stationary arranged pin. It is advantageous if the blanking plate is preferably loaded on its opposite side of the suspension with a biasing spring also arranged stationary.
  • the actuating member can be driven by a preferably hydraulic linear drive whose piston rod is coupled to the slide of the actuating member.
  • the invention provides that the linear drive is arranged with the carriage on one longitudinal side of the changing device, and that on the opposite longitudinal side a nozzle gripper is provided, with which the worn casting nozzle is removable from the changing device.
  • the nozzle gripper has a swing-out recording head with a holding magnet for the worn casting nozzle, which is attached at the end of a parallel to the direction of the casting nozzle rotating and retractable and guided operating rod. This facilitates handling and simplifies the construction of the device.
  • the changing devices after the Fig. 1 to Fig. 11 and FIGS. 12 to 18 are essentially identical. As in particular from the FIGS. 12 to 18 can be seen, they have a base plate 1, which is secured by means of wedge elements 2 on the bottom wall of a casting apparatus 3 with a spout 4. On the base plate 1 guide rails 5, 6 are mounted. They form a displacement plane for the casting pipes to be replaced or the casting nozzles to be replaced.
  • a drive system 7 is further mounted with a hydraulic linear drive 8 and an actuator 9 for the casting tubes or casting nozzles to be replaced.
  • the actuator 9 is composed of a carriage 10 and a driver 11, wherein the coupled to the piston rod of the linear drive 8 slide 10 is guided in guides 12 in the direction of displacement of the casting tubes or casting nozzles, while the driver 11 on the carriage 10 about an axis thirteenth is articulated transversely to the direction of displacement.
  • the changing devices are also provided with a blank plate 14, with which in case of emergency, the pouring channel of the casting apparatus 3 can be closed.
  • a horizontal longitudinal groove 15 and an obliquely arranged to her guide groove 16 are provided on both sides, wherein both grooves cooperate with them engaging cylindrical pins 17 on the carriage 10.
  • the change device after Fig. 11 are the grooves on the slide, while the cylinder pins placed on the blanking plate, so vice versa.
  • the cylinder pins of the blanking plate or the grooves 15, 16 associated with the carriage is in this change device after 11 to FIG. 18 achieved that the dummy plate 14, which is not illustrated in detail, pulled back into the waiting position and that consequently a new exchange nozzle can be inserted.
  • the casting process can be interrupted for a short period of time and, as a result, the casting process continues by burning the molten steel frozen in the pouring sleeve 4.
  • the blanking plate 14 is then in the waiting position over the displacement plane of the casting tubes or pouring nozzles. There it is so far offset from the displacement plane that the unused casting pipe or the unused casting nozzle is unhindered inserted under the blanking plate during the change process.
  • the latter can be coupled to the driver 11 by hack-shaped suspension elements 18, which can hook into corresponding recesses 19 of the carrier 11.
  • the blanking plate 14 is acted upon by a biasing spring 20 supported against the base plate 1 or an equivalent means.
  • the casting tube changer after the Fig. 1 / 1a to Fig. 11 / 11a works as follows: In normal operation, there is a pouring pipe 21 in the in Fig. 1 shown casting position, in which the casting tube is pressed against the him with the casting channel forming outlet sleeve 4 of the casting apparatus. Next to him is an unused spare tube 22 in waiting position. The blind plate 14 is above the replacement tube 22, also in waiting position. It is coupled to the driver 11 with the suspension elements 18 ( Fig. 1 / 1a ).
  • the driver 11 by the linear drive 8 in the direction of arrow 23 (FIG. Fig. 2 / 2a ), wherein the dummy plate 14 is moved forward and the pin 17 moves into the longitudinal groove 15 to prevent the dummy plate 14 from falling down.
  • the driver 11 then depends on the blanking plate 14 and is now able to push the replacement tube 22 into the previously occupied by the pouring tube 21 casting position ( Fig. 3 / 3a ).
  • Fig. 4 / 4a the end position of the change process is shown.
  • the driver 11 has the replacement tube 22 inserted into the casting position and pushed out the spent pouring tube 21 from the casting position, while the blanking plate 14 is still in the waiting position. Thereafter, the driver 11 by the linear drive 8 in the direction of arrow 24 ( Fig. 5 / 5a ) moved back. He hangs himself on the blind plate 14 again ( Fig. 6 / 6a ) and causes them by the interaction of the pins 17 with the oblique guide grooves 16 does not fall out ( Fig. 7 / 7a ).
  • the casting tube changer is then again in the in Fig. 8 / 8a illustrated initial situation, but in which, for example, now emergency no replacement tube is inserted in the changer. Since no replacement tube is present, the blanking plate 14 is not on and thus can be down because the pins 17 now in the guide grooves 16 in the direction of the open groove along along migrate, which is supported by the spring force of the biasing spring 20 ( Fig. 9 / 9a ).
  • the blank plate 14 drops down to the displacement plane of the casting tubes 21, 22, and the driver 11 can insert it in an emergency on the same displacement plane in the closed position ( Fig. 10 / 10a ), while in turn pushes the operating pipe 22 out of the casting position ( Fig. 11 / 11a ). In this way, the emergency closing of the pouring channel is accomplished by means of the blanking plate 14.
  • the changing device Since only a single drive system with a common actuator and a common displacement plane are available for the change process and the emergency closing, the changing device is structurally simple and reliable, because they can only perform one or the other function by design.
  • the blank plate 14 is pushed by the driver 11 on the displacement plane of the casting nozzle 25 ( Fig. 14 ) until it pushes them out of the casting position.
  • the final closed position Fig. 15
  • the blanking plate 14 is now in the casting position, in which it completely interrupts the casting channel of the casting device.
  • the Giessdüsenwechsler after the FIGS. 16 to 18 is essentially the same as the one after the FIGS. 12 to 15 constructed, but additionally has a nozzle gripper 27 for removing the worn casting nozzles.
  • the nozzle gripper 27 has a receiving head 28 with a holding magnet 29 for the worn casting nozzles, which is attached to a pivot arm 30 of a parallel to the direction of rotation and retractable and extendable operating rod 31 with a handle 32.
