Definitions

  • the invention relates to a rotary slide closure for metallurgical melting vessels according to the preamble of claim 1 (DE-A-1910247).
  • the object of the present invention is a practical design of a rotary slide closure in such a way that easy maintenance of the closure and rapid replacement of the refractory closure body are possible even with the sliding surface shifted far towards the interior of the vessel.
  • the invention offers the possibility of using the widespread and simple plate form of the refractory closure bodies even for deep installation. It can be adjusted with little effort, namely by adjusting the pipe length, the installation depth to the particular circumstances, such as. B. changing thickness of the vessel lining, etc.
  • the mechanically more sensitive parts of the closure such as spring elements and bearings, can be accommodated outside the vessel jacket in the region of relatively low temperatures.
  • fire-proof in the context of the present invention is of course generally to be understood in such a way that the relevant parts or materials that come into direct contact with the melt are sufficiently resistant to it should.
  • the rotary slide closure shown in Fig. 1 is attached to a metallurgical melt vessel for the purpose of emptying the melt contained in it, by being detachably attached to the metallic vessel jacket 2 (or an intermediate plate inserted, e.g. welded in, for example, in the jacket plate) by means of several screws 19.
  • a part of the refractory lining 4 lying inside the vessel jacket-2 is shown.
  • a refractory sleeve 6 which is arranged above an opening 3 of the vessel jacket and to which an outlet stone 8 provided with a wide funnel opening 9 is connected via an annular mortar joint 7, is embedded in it.
  • the refractory parts 6 and 8 can remain installed for a longer period of time and need z.
  • the upper end face of the closure is separated from the underside of the outlet stone 8 by an annular mortar joint 1 which surrounds the opening 9 and an insulating layer 5 adjoining it on the outside, preferably made of a fireproof felt mat; Parts 1 and 5 must be replaced when the locking unit is reinstalled.
  • the stationary, refractory pouring body 20 lying below the opening 9 and the rotatable, fireproof slide body 40 are designed as flat, preferably identical plates.
  • the sliding surface 23, on which the slide plate 40 rests under prestress on the pouring plate 20, is located on the side of the vessel jacket 2 facing the interior of the vessel, as a result of which the pouring area is kept at a relatively high temperature by the melt contained in the vessel; this is further supported by the wide opening 9, which creates a large contact area between the melt and the plate 20.
  • an opening 42 present in it can be brought into line with the stationary opening 22 or the latter opening can be closed; as usual, the slide plate 40 can also contain a plurality of openings.
  • the stationary plate 20 and the slide plate 40 are each held at one end of a stationary or rotatable closure part.
  • the stationary and also the rotatable closure part are essentially designed as coaxial tubular bodies; the slide plate 40 is held on the rotatable tubular body 30 indirectly via an intermediate carrier 34 the rotatable closure part are guided radially and axially to one another via two roller bearings 24, 25.
  • the stationary closure part is divided into several tubular longitudinal sections 10, 11 and 12. At the connection points of these parts, heat-insulating layers 26 and 27, 28 are inserted, which greatly restrict the heat dissipation to the outside via the fixed, metallic tubular body from the closure area.
  • the end section 10 is detachably connected to the middle section 11 by means of several screws 15 and has an end face 14 in which the plate 20 is inserted.
  • the pipe sections 11 and 12 are each provided with a flange 16 and 17 and connected to this by means of a number of screws 18.
  • One flange 16 is used for positioning and fastening (screws 19) the entire closure unit on the vessel jacket 2.
  • the tubular body 30 of the rotatable closure part is mounted on the tube section 12 lying outside the vessel jacket.
  • a tangential wedge 35 guided in the latter is used, which lies against a lateral driving surface of the otherwise circular plate 40.
  • the stationary plate 20 is secured against rotation in the bottom surface 14 of the end section 10 by means of a wedge 21.
  • a thermal insulation 43 is inserted in the intermediate carrier 34, which inhibits the heat radiation from the slide plate to the outside.
  • a pouring tube 44 is also used, which protects the metallic components of the closure from the outflowing melt.
  • the two parts 43 and 44 can be made in one piece or separately from light and porous, e.g. B. fibrous or flaky refractory material.
  • the intermediate carrier 34 rests on the upper ends of three pressure rams 38, which, offset from the driving bolts 37, are guided so as to be longitudinally movable in the tubular body 30.
  • a ring 46 which z. B.
  • three circumferentially distributed spring members 48 is applied.
  • These are preferably disc springs 48 which are stacked in packages on a stud bolt 47 and are preloaded with a nut 49.
  • the intermediate support 34 with the plate 40 is able to perform a certain wobble movement relative to the tubular body 30, the full support of the plate 40 on the plate 20 (sliding surface 23) is maintained during the rotation even if the rotatable tubular body is not precise should be aligned coaxially to the stationary tubular body.
  • a turntable 31 is fastened by means of several screws 33, which with the toothing 32 serves the rotary drive (by means of a chain or spur gear) of the rotatable closure part.
  • the slewing ring 31 is preferably bell-shaped and engages over the outer end of the stationary closure part, as a result of which the toothing 32 comes to lie axially between the bearings 24 and 25.
  • the rotary slide closure described can be removed by loosening the screws 19 as a whole from the depression formed by the refractory parts 6 and 8. This makes the screws 15 accessible and the end section 10 of the fixed closure part can be loosened for the purpose of checking or replacing the plates 20 and 40. After the end section 10 has been reattached and any resetting of the spring members 48, the closure unit as a whole can be reinstalled. There is also the possibility of leaving the screws 19 and, on the other hand, loosening the screws 18 connecting the flanges 16 and 17, whereupon the pipe section 12 with the rotatable closure part mounted thereon can be removed, but the stationary pipe sections 10 and 11 and the plate 20 stay installed.
  • the described closure construction enables particularly simple maintenance and, in particular, rapid replacement of the refractory closure bodies 20 and 40.
  • the construction can also be very easily adapted to the respectively required installation depth or position of the sliding surface 23 with respect to the vessel shell, namely only by changing the length of the tube section 11 and of the rotatable tubular body 30; if necessary, this can be achieved by inserting intermediate rings of different lengths on these parts.
  • the rotary slide closure according to the invention can be used for casting various melts, in particular also non-ferrous heavy metals or light metals from the respective melting vessels. Operation is not only possible in the vertical position shown, but also with a horizontal or inclined axis of rotation.
