Definitions

  • the invention relates to a sliding closure for a container containing molten metal, with a attachable to a spout of the container housing frame for receiving a refractory base plate and a slide unit with a sealable to the bottom plate by means of spring members refractory slide plate, wherein the slide unit by means of a drive member movable back and forth is.
  • a sliding closure of this type is in the document EP 0 819 488 B1 described. It is preferably used to open and close the spout opening of converters. In the foundry, its refractories are strong Wear exposed. It is therefore necessary to exchange them relatively frequently. The replacement is feasible only after removal of the sliding closure. Thus, the productivity of the plant is compromised due to the resulting downtime. This is especially true when using the slide fastener in converters, because experience has shown that the bottom plate wears quickly and you must therefore replace them relatively often, at least more often than the other refractory parts.
  • the invention has for its object to avoid these disadvantages and to provide a sliding closure of the type mentioned, which allows a quick and convenient replacement of particularly vulnerable refractory parts, without the need for interrupting the casting operation.
  • the cassette is provided with a second bottom plate arranged next to the bottom plate and in the housing frame transversely to the direction of movement of the slide unit from an initial position in which the bottom plate is in the operating position to an end position in which the second bottom plate assumes the operating position, is displaceable.
  • the invention provides that the cassette with the bottom plate and the second bottom plate between its initial position and its end position is displaced back and forth.
  • the displacement path is either on one side to the left or right of the slider unit, or arranged on both sides left and right of the slider unit.
  • the cassette is displaceable in a two-part support plate of the housing frame, which is provided with stepped guide profiles for guiding the cassette in the direction of displacement. In this way, the exact positioning of the second base plate in the operating position is ensured when changing the plate.
  • the invention provides that the cassette is displaceable by a transverse drive attached to the container with a push rod pushing the cassette.
  • the push rod can be coupled to the cassette, which is then displaced back and forth by the transverse drive.
  • the transverse drive is designed in a structurally simple variant as a manual drive, which is provided with an actuating lever for the push rod.
  • transverse drive is designed as a hydraulic linear drive
  • the push rod is actuated by a hydraulic cylinder. This embodiment provides a more convenient handling.
  • the transverse drive is firmly mounted on the base plate, so that it remains fixed when dismantling the sliding closure on the container.
  • the housing frame of the slide fastener suspension and fixing means for releasably securing the housing frame to the base plate of the container.
  • the drive member for the slider unit is attached to the base plate and the slider unit can be coupled to the drive member by means of a releasable coupling.
  • the cassette is formed with two closely juxtaposed enclosures for play-free receiving octagonal bottom and second bottom plate, wherein the longitudinal edges of the cassette are provided with a stepped guide profile.
  • Such a cassette can also be retrofitted without much effort in existing sliding closures.
  • the sliding closure 1 according to the FIGS. 1 to 9 is arranged on the spout of a converter, of which only one sliding shutter 1 bearing base plate 2 is visible in the figures.
  • the sliding closure 1 has a housing frame 3 with a cassette 4, in which a refractory base plate 5 and a likewise refractory second base plate 6 are inserted.
  • a slide unit 7 is further arranged with a refractory slide plate 8 and an adjoining refractory spout 9.
  • the slider unit 7 is between the open position according to Fig. 4 and the closing position according to Fig. 6 slidable on lateral slide rails 10, which are held in the housing frame 3 and acted upon by spring members 11.
  • the slide unit 7 is actuated by a coupling rod coupled to it 12, which in turn is connectable by a releasable coupling 13 with a cylinder piston drive, not shown.
  • a stop flange 15 is provided on the base plate 2, which cooperates with annular surfaces 14 of the push rod 12.
  • the housing frame 3 with the cassette 4 and the slide unit 7 is frontally suspended from the base plate 2 by means of pins 16, which protrude into holders 17 of the base plate.
  • fastening elements 18 are provided in the form of threaded bolts in this on the opposite side, which can be pivoted into grooves 19 of two lateral flanges 20 of the housing frame 3. The latter is clamped against the base plate 2 with nuts screwed over the flanges 20 onto the threaded bolts.
  • a disc-shaped refractory head portion 21 is provided in continuation of the spout, not shown, of the converter.
  • the illustrated braced state of the sliding closure 1 is a transversely through the slide unit 7 and the superimposed one of the spring members 11 Slide and bottom plates 8 and 5 produced to the head part 21 extending power flow, which ensures that between the plates 8, 5 and the head part 21 during casting no molten steel can flow out.
  • the spout 9 is in turn pressed against the slide plate 8 by a spring-loaded support ring 22 sealingly.
  • the cassette 4 with the bottom plate 5 and the second bottom plate 6 is formed by a rectangular steel plate which is displaceable in a two-part support plate 23, 24 of the housing frame 3 transversely to the direction of displacement of the slide unit 7.
  • the cassette 4 has at its longitudinal edges stepped guide profiles which cooperate with correspondingly formed guide profiles 25 of the two-part support plate 23, 24. As a result, the cassette 4 is securely guided in the support plate 23, 24 in the direction of displacement.
  • the stepped formation of the profiles causes the cassette to fall out of the body frame.
  • the cassette 4 has two closely juxtaposed enclosures 26, in which the bottom plate 5 and the second bottom plate 6 are inserted without play.
  • the enclosures 26 are formed in accordance with the outer contour of the plates 5 and 6 octagonal. This ensures an immovable positioning of both plates.
  • the bezels 26 have a stepped profile that matches the outer contour of the plates 5 and 6 and, in turn, prevents the plates from falling out of the housing frame.
  • the cassette 4 can between the in Fig. 7 shown starting position, in which the bottom plate 5 is in the operating position, and a in Fig. 8 shown position in which the second base plate 6 assumes the operating position, are moved.
  • a transverse drive is provided.
  • This one is in a first embodiment variant as a manual drive 27 and in a second variant as a hydraulic cylinder-piston drive 28 is formed.
  • the transverse drive 27 is mounted on the base plate 2 and provided with a push rod 29 or 30, which is effective on the cassette 4 at the level of the through hole of the bottom plates 5 and 6.
  • this respective transverse drive 27 or 28 could also be brought into position independently of the base plate 2, in order to then perform a displacement of the cassette with the bottom plates can.
  • the push rod 29 is driven by a force acting on a pin 31 of the push rod actuating lever 33 which is mounted in a fixed to the base plate 2 box 32 and laterally protrudes from the box to allow manual operation.
  • the push rod 30 is guided in a holder 34 which has a flange 36 to which the hydraulic cylinder 35 of the hydraulic transverse drive is attached.
  • the respective push rod 29 or 30 is not coupled to the cassette 4, so that they can move the cassette in only one direction.
  • the sliding closure 1 allows the replacement of the base plate 5 after reaching its maximum permissible wear, without that it is necessary to interrupt the casting operation.
  • the cassette 4 with the aid of the transverse drive 27 and 28 transversely to the direction of movement of the slide unit 7 so far moved until the worn bottom plate 5, the in FIG. 7 has cleared operating position and the second bottom plate 6 occupies it. Since in this case the plate exchange takes place while maintaining the force flow generated by the spring members 11, it is ensured that the sliding closure continues to seal properly both during the plate change and thereafter.
  • the plate change is carried out without having to reduce the slide fastener, it is at any time possible with the sliding closure according to the invention to replace the base plate quickly and with simple handling.
  • This is advantageous in casting operation, especially in converters, because experience shows that the bottom plate wears out faster than the other refractory parts of the device. This makes it possible to maintain the casting operation longer until the replacement of the other refractory parts is due.
  • the sliding closure 1 is removed in a known manner by the supporting base plate 2 of the container.
  • the fixing means 18 are released, which are effective on the flanges 20 of the housing frame 3.
  • the force acting on the refractory parts clamping force of the spring members 11 is reduced.
  • the pins 16 are removed from the bearing blocks 17, and the sliding closure 1 is transported by means of a manipulator, not shown, to a station in which the replacement of the worn refractory parts including the bottom and second bottom plate takes place.
  • the cassette 4 is easily removed from the housing frame 3, to easily get to the underlying refractory parts.
  • the housing frame 3 is pivoted away from the base plate 2 together with the base plates, the slide plate and the spout located therein. It can then, for example, the refractory parts removed from this housing frame and replaced. It is desirable to replace with each change of refractory parts and the remaining in the base plate 2 refractory head part 21 so that it is ensured in a subsequent displacement of the bottom plates that between them and the head part, the tightness is properly guaranteed.
  • Fig. 10 illustrates how the housing frame 3 is mounted to the base plate 2 with the refractory parts mounted therein by this housing frame 3 is pivoted about the axis A formed by the pin 16 and thus fixed by the fastening elements 18 on this base plate 2.
  • the spring elements 11 in the housing frame By the spring elements 11 in the housing frame, the refractory parts, as explained above, clamped for the intended seal against each other.
  • spring members 11 are provided in the invention with such a spring characteristic that in the Einschwenkposition of the housing frame 3, as shown, in which the bottom plate 5 with its one end edge 5 'with the lower end face 21' of the head part 21 comes into contact, very low contact forces act, thus damaging these normally made of ceramic material refractory parts should be prevented. If the bottom plate 5 rests flat against this end face 21 ', there is still a linear movement of the housing frame until it is present on the base plate 2 of the converter, then the full spring force of the spring members 11 acts.
  • the sliding closure 1 described is equipped with a single transverse drive 27 or 28.
  • the cassette according to the invention with the associated transverse drive can also be retrofitted into existing sliding closure devices of the type mentioned at the outset without great expense.
