Definitions

  • the invention relates to a slide closure for the pouring of metallurgical vessels, preferably steel ladles, with a closure housing and an adjustable slide frame which carries a slide plate and which, for the purpose of pressing the slide plate onto a stationary base plate along its guideway, is loaded with rocker arms loaded with spring elements and at one end with supports is supported, wherein the rocker arms are arranged in the direction of the guideway or in the direction of adjustment of the slide frame with transverse transverse axes together with the spring elements in the closure housing.
  • a sliding closure of this type is previously known from the publications SU-A-772715, on which the preamble of claim 1 is based, SU-A-768556 and SU-A-1053961.
  • the slide lock is provided with two rocker arms arranged on both sides of the lock opening, the supports of which press against an unadjustable support frame at the height of the lock opening, in which the slide frame of the slide plate is adjustable. This results in a merely linear and thus unstable pressing of the slide plate against the stationary base plate.
  • the two rocker arms must be very long because they alone have to exert the entire contact pressure.
  • the rocker arms are also arranged on the side of the stationary support frame and thus far outside the slide plate.
  • the invention has for its object to avoid the disadvantages of the above prior art and to provide a slide closure of the type mentioned, which ensures a metal-tight pressing of the slide plate to the base plate, and this with a simple structure and space-saving dimensions.
  • the slide closure is provided with four rocker arms, the support of which forms a support plane for the slide frame of the slide plate.
  • Such a construction has the advantage of a flat and thus uniform pressing of the slide plate against the stationary base plate, which is particularly effective on the full circumference of the through hole of the closure.
  • rocker arms can have significantly smaller dimensions. They are also located directly under the slide frame and close to the long sides of the slide plate. Both are very cheap in terms of a compact design.
  • the sliding frame of which is rotatable or pivotable provides that the tilting axes of the rocker arms and / or the axes of their supports are arranged radially to the pivoting or pivoting axis. This provides constructive, expedient and reliable arrangements and designs of the rocker arms along a circular or arcuate guideway.
  • rocker arms and the spring members are expediently arranged in a removable or swiveling housing cover, which has the advantage of easy access to the two closure plates.
  • 1 means the steel jacket of a metallurgical vessel shown in the bottom region, which has a perforated brick 2 on the inside, in the refractory lining, not shown, into which a two-part pouring sleeve 3 is inserted, the flow opening 4 of which extends linearly into the inlet adjustable slide closure 5 forms.
  • the refractory slide plate 10, which also has a flow opening 9, and the refractory outlet sleeve 11 lie against the base plate 7.
  • sliding frame 12 Both are supported in a sliding frame 12, which in turn is mounted on the housing 6 in a joint 13 and articulated lever 14 held housing cover 15 is arranged.
  • the sliding frame 12 can be adjusted linearly by means of a force transducer 16, which is indicated, for opening and closing the slide closure 5, while at the same time sealingly pressing the slide plate 10 against the base plate 7 with the aid of two-armed rocker arms 18 which are loaded by spring elements 17 and act between the housing cover 15 and the sliding frame 12.
  • the sliding frame 12 is equipped on each longitudinal side with a guide bar 19, which are used both for lateral guidance on the housing cover 15 and for bearing on rollers 20 with axles 21 designed as supports of the rocker arms 18 provided in pairs under each guide bar 19.
  • These rocker arms 18 are aligned in the longitudinal direction of the guideway of the sliding frame 12 formed by the guide strips 19 or with tilting axes 22 lying transversely thereto in the housing cover 15. Furthermore, they act together with the spring elements 17, which are positioned outside the stroke path covered by the sliding frame 12 in the housing cover 15.
  • the rocker arm rollers 20, which transmit the force of the spring members 17 to the sliding frame 12 when the housing cover 15 is closed, are grouped symmetrically about the pouring spout 23 or around the coaxial flow openings 4 and 8 of the pouring sleeve 3 and base plate 7, that is to say specifically on that for sealing the bottom plate 7 and the slide plate 10 relevant plate area.
  • the ferrostatic pressure and the flowing pouring jet have a direct effect there.
  • the tension ratio of which to the spring members 17 can be adjusted by means of screws 24, sliding shoes 25, for example, which are largely insensitive to dirt, can also be used.
  • the rocker arms with one arm, i.e. to provide their tilting axes 22 at the end of the rocker arm 18 which is free of support and to insert the spring members 17 between the rollers 20 or sliding blocks 25 used as supports.
  • the separate guide strips 19 can be components of the slide frame 12.
  • the rocker arms 30 are adapted to the circular guideway 31 of a sliding frame, indicated by dash-dotted lines and carrying the refractory slide plate, not shown, designed as a rotating basket.
  • This is elastically supported with its tilting axles 33, which are oriented transversely to the guideway 31 in the housing cover 34 and acted upon by the spring members 35, via their sliding rollers 36 in order to achieve the required tight pressure of the slide plate on the base plate.
  • the axes 37 of the rollers 36 also run radially in accordance with the tilt axes 33, which is not necessary when using immovable sliding shoes on the rocker arms 30, which can then also have an elongated shape which is not matched to the arcuate guideway 31.
