Definitions

  • the invention relates to a sliding closure according to the preamble of Claim 1; and an associated slide unit.
  • a longitudinally displaceable, receiving a fire-proof closure plate Slider unit is provided, which is designed as a slide carriage and therefore has rollers on both sides for its longitudinal guidance.
  • the carriage is in condition with its rollers on guideways Frame guided longitudinally, which in turn is adjustable in height by means of several spring elements is held on an upper housing part.
  • the upper part of the housing in turn is detachable at the pouring point of the vessel containing the molten metal attached.
  • the slide unit can be used in particular for a plate change from the frame and be detached from the upper part of the housing by moving it into an outside an open and closed position is displaceable in the the guideways by a height relaxing the spring elements are lowered.
  • the frame with the guideways is through its housing-like design is massive and it is therefore relatively expensive and therefore built expensive to manufacture.
  • the present invention was based on the object a sliding closure according to the type mentioned at the beginning create, which consists of a simple construction and therefore in the Manufacturing is cheaper to manufacture.
  • This sliding closure according to the invention can be compared to the one explained above known closure with the same stroke and the same plate sizes provided with smaller dimensions, in particular in its length and width become. Furthermore, this can be due to the fact that can be dispensed with the housing frame, produce less expensive.
  • FIG. 1 shows a slide closure 20 on the spout of a molten metal containing container. From this container, which is filled with refractory material is lined, just the outer steel jacket 13 and a refractory Hole brick 17 indicated. This container is in particular around a ladle used in a continuous caster, into the molten steel is filled.
  • a fireproof sleeve 11 forms the pouring opening 12 of the container, to which an upper refractory closure plate 22 tightly connects, which is fastened in a housing part 14 of the slide closure 20 is.
  • Locking plate 23 is connected to the upper plate 22 by means of spring members 26 pressed.
  • An exchangeable refractory pouring sleeve also connects to the latter 16 on. This plate 23 serves to open or close the closure 20, for this purpose they together with the slide unit holding them 30 slidably arranged by a drive member.
  • the slide unit 30 is perpendicular to several of them Holding means 40 extending longitudinally longitudinally on Housing part 14 held, these holding means 40 each on the housing part 14 are attached and have a guide means opposite, which each on a guideway formed on the slide unit 30 36 slides.
  • Holding means 40 are provided which are symmetrical to the pouring opening 12 of the Container are arranged and each perpendicular to the longitudinal extent of the housing part 14 or the slide unit 30 extending bolt-shaped Have link 25.
  • These links 25 are each held and adjustable in its axial direction in the housing part 14 their respective upper head disks 25 'by a compression spring Spring member 26 acts, the latter in a sleeve 28th is encapsulated.
  • Two slide rollers 27, which are provided as guide means, are rotatably mounted on each the slide unit 30 is longitudinally guided.
  • the latter has for this purpose on both sides of the closure plate 23 that can be inserted into it, one in its direction of displacement running T-groove-shaped recess 33, in each of two Guideways 36 are formed.
  • This symmetrical arrangement of the Coupling roller pairs to the line of action of those generated by the spring element 26 Spring force enables optimal power transmission from the holding means 40 on the slide unit 30 and subsequently on those to be pressed against each other Plates 22, 23.
  • FIG. 2 they are laterally in the slide unit 30 as invisible illustrated T-groove-shaped recesses 33 in the middle and provided at the end with a widening opening 33 'which is dimensioned in this way and each other, that the connecting links 25 can be inserted into and out of these together with the guide rollers 27 can be removed.
  • the hinge 37, 38 could also be on the other side of the slide unit 30 or on the shorter side facing away from the drive.
  • the slide unit can, depending on the placement of the closure Pan spout can be swung out on one of the three sides.
  • the direction of displacement of the slide unit at the assembly site runs in the vertical direction, the slide unit in the shown arrangement can be pivoted horizontally, what with little Force is connected.
  • the two located on one side of the closure plates 22, 23 Holding means 40 are for stabilization against the bending forces that occur stiffened by at least one connecting rod 31, 32 and thereby form a car shape.
  • the two connecting rods provided here 31, 32 are located centrally in the recess 33. They point a width which approximately corresponds to that of the connecting links 25, so that they are inserted into and out of the recess 33 can be.
  • the connecting links 25 are further divided into two and assembled by a tongue and groove connection 25 "or the like. In principle, these connecting rods 31, 32 could also to be dispensed with. Instead of the sliding rollers 27, sliding blocks could be used become.
  • these holding means 40 can be used within the scope of the invention with the slider unit 30 pivoted out laterally from the housing part 14 in packets be taken away. Corresponding are in the housing part 14 for this purpose Recesses 15 are available in which the holding means fit can be inserted. From this, the spring members 26 for the quickly remove the necessary checks of their tension and reinstate.
  • the slide unit 30 are transverse and in its central part Longitudinal ribs 30 'assigned, which reinforce the same against bending and serve torsional forces.
  • the slide closure 20 is otherwise illustrated in the closed position.
  • FIG. 5 shows a variant of a slide closure 50, which in itself similar to that of Fig.1 is constructed. It is therefore below just explained the differences.
  • This slide closure 50 has again a housing part 54 fastened to the container, in which one stationary refractory closure plate 22 is included.
  • the holding means 65 are not a major difference compared to the closure 20 Housing part 54, but attached to the slide unit 60.
  • the axially movable Links 55 are together with that of several disc springs formed spring members 66 in a recess 61 of the slide unit 60 held.
  • As a guide means are again advantageous four connecting links 55, each on a horizontal axis 69 rotatable roller 68 assigned, which on a similar to that 3 guideway 71 slides on the housing part 54.
  • the extend two guideways 71 provided laterally on the housing part themselves in the direction of displacement of the slide unit and they are not closer to shown ramps, which for loading and unloading the spring elements 66 serve.
  • the inventive slide closures 20, 50 each have both the housing part 14, 54 and the slide unit 30, 60 each have a plate-like training and they are in the operating state arranged parallel and at a short distance from each other.
  • These sliding closures 20, 50 can therefore be based on these according to the invention Training in its dimensions can be kept as small as possible, be it with Regarding the overall height as well as its length and width. From this results a cheaper production of the same. That closure can be used both in smaller dimensions for smaller pans to 100 tons capacity as well as in larger dimensions for 300 Barrel pans are made.
  • the spring package required for bracing the refractory could Plates against each other in a manner known per se between the Slider plate and the slide unit can be provided.
  • the holding means could accordingly not be displaceable in the housing part or in the Slider unit can be arranged.
