Definitions
- the invention relates to a casting tube changer for a casting apparatus for producing metallurgical products, comprising an actuating member for displacing an unused pouring tube from a waiting position into the pouring position, in which the pouring tube is pressed against an outlet sleeve of the pouring device forming a pouring channel therewith.
- 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.
- CONFIRMATION COPY 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 moving the new pouring tube into the pouring position, taking along the worn pouring tube.
- a changing device of this kind is disclosed in EP 0 714 332. It is characterized essentially by the fact that it has an additional plate lying between the top plates of the spent pouring tube and the unused replacement tube, wherein the displaced pouring tube is pushed by the additional plate on the casting position when moving the replacement tube in the casting position.
- the casting tube changer does not contain any means for the rapid closing of the pouring channel in emergencies, for example in the case of casting pipe breaks or similar serious occurrences. This is disadvantageous in terms of the reliability of the system.
- 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. This object is achieved according to the features of claim 1.
- 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 a guide groove lying obliquely to it, which cooperate with a stationarily 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.
- Fig. 1/1 a changing device for casting tubes, partially shown in section and in the starting position,
- Fig. 9 / 9a the changing device of FIG. 1, shown at initiation of an emergency closing process.
- FIG. 1 the changing device from FIG. 1, with the blanking plate inserted into the closed position, FIG.
- FIGS. 12 to 15 show a changing device for casting nozzles, shown in four different phases of an emergency closing operation.
- Nozzle gripper for the worn casting nozzles with extended gripper
- Fig. 17 the changing device of FIG. 16, shown with swung-out gripper
- the changing devices according to FIGS. 1 to 11 and FIGS. 12 to 18 are constructed essentially identically. As can be seen in particular from FIGS. 12 to 18, they have a base plate 1, which is fastened by means of wedge elements 2 to the bottom wall of a casting device 3 with a pouring sleeve 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 1 1, wherein the coupled to the piston rod of the linear drive 8 carriage 10 is guided in guides 12 in the direction of the casting tubes or casting nozzles, while the driver 1 1 on the carriage 10 to a Axis 13 is articulated transversely to the direction of displacement.
- the changing devices are also provided with a blind plate 14, with which the casting channel of the casting device 3 can be closed in an emergency.
- 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.
- both grooves cooperate with them engaging cylindrical pins 17 on the carriage 10.
- the changing device according to Fig. 1 1 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 achieved in this changing device according to Fig. 1 1 to Fig. 18 that the blind plate 14, which is not illustrated in detail, retracted 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 1 1 by hackenförmige suspension elements 18 which can hook into corresponding recesses 19 of the driver 1 1.
- 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 according to FIGS. 1/1 a to 1 1/1 1 a operates as follows: In normal operation, there is a pouring tube 21 in the casting position shown in FIG. 1, in which the pouring tube is pressed against the outlet sleeve 4 of the pouring device which forms the pouring channel with it. 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. 1/1 a).
- the driver 11 is driven by the linear drive 8 in the direction of arrow 23 (Fig, 2 / 2a), wherein the blank plate 14 is moved forward and the pin 17 moves into the longitudinal groove 15 to prevent the Dummy plate 14 falls down.
- the driver 11 then depends on the blind 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 1 1 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 is moved back by the linear drive 8 in the direction of the arrow 24 (Fig. 5 / 5a). It rests against the blanking plate 14 again (FIG. 6 / 6a) and causes it not to fall out due to the cooperation of the pins 17 with the oblique guide grooves 16 (FIG. 7 / 7a).
- the casting tube changer is then again in the starting position illustrated in FIG. 8 / 8a, in which, however, due to emergencies, for example, more no replacement tube is inserted in the changing device. Since no replacement tube is present, the blank 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 blind plate 14 drops down to the sliding plane of the casting tubes 21, 22, and the driver 11 can insert it in the emergency on the same displacement plane in the closed position (Fig. 10710a), while in turn pushes out the in-use pouring tube 22 from the casting position ( Fig. 1 1/1 a). 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 operation of the Giessdüsenwechslers according to FIGS. 12 to 15 is identical to that of the tube changer according to FIGS. 1/1 a to 11/11 a.
- the casting nozzle 25 In the starting position shown in FIG. 12, the casting nozzle 25 is in the casting position, while the blanking plate 14 is in the waiting position. It is held up by the inserted into the guide 16 pins 17.
- the driver 11 is driven by the linear drive 8 in the direction of the arrow 26 (FIG. 13).
- the pencils 17 slide along the guide grooves 16 and thus allow the blind plate 14 to the sliding plane of the casting nozzle 25 is lowered.
- the blank plate 14 is pushed by the driver 11 on the displacement plane of the casting nozzle 25 (FIG. 14) until it pushes it 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 pouring channel of the casting device.
- the casting nozzle changer according to FIGS. 16 to 18 is substantially identical to that of FIGS. 12 to 15, 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 extendable and retractable guided actuating rod 31 with a handle 32.
- the receiving head 29 is pulled out with the actuating rod 31 in the direction of the arrow 33 (FIG. 16), then swung out in the direction of the arrow 34 (FIG. 17), and then moves in the direction of the arrow 35 (FIG ) to a delivery point for the worn casting nozzle.
