Definitions

  • the invention relates to a sliding closure for a metallurgical vessel according to the preamble to Claim 1 .
  • the object which forms the basis of the present invention is to provide a sliding closure of the type specified at the start wherein the danger of the plate bracing being negatively effected during operation will be largely eliminated.
  • FIG. 1 a top view of a metal frame with a slide plate braced therein by means of a bracing device as part of a sliding closure according to the invention
  • FIG. 2 the metal frame with the slide plate according to FIG. 1 and with the bracing device in an ineffectual position.
  • FIGS. 1 and 2 part of a sliding closure usable on the spout of a metallurgical vessel is shown which comprises a metal frame 1 and a refractory elongated slide plate 2 exchangeably arranged in the metal frame 1 .
  • the slide plate 2 provided with an aperture 5 is braced in the metal frame 1 by means of a bracing device 3 .
  • FIG. 1 shows the bracing device 3 in its effectual position
  • FIG. 2 the ineffectual position of the bracing device 3 is illustrated in which, for example, a plate exchange can be implemented.
  • the metal frame 1 can also be a housing part of the sliding closure with which the slide plate is not moveable itself, but is also subjected to an oscillatory force by the oscillating slide plate adjacent to the latter.
  • the slide plate 2 is the moveable slide plate of the sliding closure, which by being displaced in its longitudinal direction L in relation to at least one fixed slide plate enables the spout of the container, e.g. of a steel foundry ladle or of an intermediate distributor to be closed, restricted or opened in a way known in its own right.
  • the metal frame 1 accommodating the slide plate 2 can be coupled with its end part 4 to a drive likewise in a way known in its own right and so not described in any greater detail.
  • the bracing device 3 comprises a wedge shoe 10 adjustable transversely to the direction of displacement of the sliding closure, loaded with a spring 9 , and which is operatively connected to a counterpart 11 which can be brought into form lock and friction lock connection with the slide plate 2 and acts on the slide plate 2 in its longitudinal direction L.
  • the counterpart 11 which has contact surfaces 12 , 13 corresponding to the peripheral shape of the slide plate 2 is displaceably moved within the metal frame 1 in the longitudinal direction L of the slide plate 2 .
  • corresponding guide surfaces 14 , 15 are produced in side walls 16 , 17 of a substantially U-shaped recess 20 in the metal frame 1 .
  • the wedge shoe 10 lying with its wedge surface 18 on a counter wedge surface 19 is supported here on a transverse wall 21 connecting the side walls 16 , 17 of the recess 20 .
  • the spring 9 loading the wedge shoe 10 is supported between the wedge shoe and the one side wall 16 .
  • the wedge shoe 10 is screw-connected to an adjustable screw 26 passed loosely through an opening 25 of the metal frame 1 transversely to the longitudinal direction L of the slide plate 2 , and said adjustable screw is screwed into a pin 28 inserted into the wedge shoe 10 and provided with a threaded hole 27 .
  • the adjustable screw 26 and the pin 38 are arranged at right angles in relation to one another.
  • the adjustable screw 26 has a screw head 29 which, when the adjustable screw 26 is manipulated in a direction of rotation comes to rest on a ledge surface 30 ( FIG. 2 ) of the opening 25 .
  • a banking pin 33 is inserted into the metal frame 1 which engages in an elongated recess 34 in the adjustable screw 26 and interacts with a stop surface 35 of the latter.
  • the spring 9 acting on the wedge shoe 10 is arranged co-axially to the adjustable screw 26 .
  • the wedge shoe 10 and the counterpart 11 are operatively connected to one another, not only by means of their wedge surfaces 18 , 19 , but also by means of guide surfaces 32 so that the adjustment of the wedge shoe 10 transversely to the direction of displacement of the closure in both directions results in a corresponding adjustment of the counterpart 11 in longitudinal direction L.
  • the adjustable screw 26 is manipulated in the other direction of rotation, by means of which the wedge shoe 10 is moved in the direction of force of the spring 9 and the counterpart 11 is moved back to the slide plate 2 .
  • the slide plate 2 is braced by the force of the spring 9 , the adjustable screw 26 moving away from the ledge surface 30 when the screw head 29 is manipulated further until the positioning movement is stopped by the banking pin 33 which comes to rest on the stop surface 35 .
  • the banking pin 33 prevents the adjustable screw 26 from being able to be unscrewed right out of the wedge screw and its pin 28 .
  • the presence of the pin 28 is not absolutely necessary.
  • the adjustable screw 26 could also be screwed directly into the wedge shoe 10 .
  • the pin 28 advantageously allows a certain amount of freedom from play for individual parts of the pre-tensioning device 3 .
  • the set angle of the wedge shoe 10 or of the counterpart 11 is approx. 10°. Care should be taken here to ensure that this chosen angle is not too small so that there is no self-locking so that the wedge shoe would become clamped too strongly.
  • This set angle is preferably between 3 and 15°.
