Definitions

  • the invention relates to a slide closure for a metallurgical vessel with a tap hole for pouring off molten metal or slag, with a slide housing that can be attached to the vessel and a closure plate that can be displaced therein for opening and closing the tap hole.
  • the invention is based on the object of creating a sliding lock of the type mentioned at the outset which, with a structurally simple structure, enables high operational reliability and simple operation and maintenance.
  • this object is achieved in that the sliding lock only has this sliding locking plate in the slide housing without a stationary locking plate.
  • Such a sliding closure offers several advantages over a conventional one with two or more closure plates. On the one hand, it consists of fewer components and is therefore cheaper to manufacture, because the sleeve block, the closure plate and also the pouring sleeve can be made of an inexpensive metal material such as copper or steel.
  • the slide lock is less prone to failure and also requires easier maintenance. It also eliminates the need for the otherwise necessary operation of manually plugging the tap hole in order to close it.
  • the sliding closure according to the invention can easily be adapted to each tapping hole. It goes without saying that these advantages are not limited to the use of the slide closure for pouring off slag.
  • the invention also provides that the closure plate of the sliding lock is pressed against the sliding surface of the furnace by tensioning elements arranged in the valve housing, which are relaxed when the locking plate is moved outside of their area of action and there enable the locking plate to be pivoted out of the valve housing in the unloaded state. In this way, the closure plate can be easily inspected and, if necessary, replaced without the need for complex manipulations.
  • the invention also provides that the closure plate is mounted in a slide carriage with rollers, preferably arranged in pairs, which run along guides of a support frame of the slide housing that is loaded by the bracing elements, the guides being outside the effective range of the Closure plate are designed as ramps, the inclination of which is dimensioned such that the guides are lowered there by a height amount that relaxes the tensioning organs. In this way it is possible to reduce the tension of the Relieve tensioning organs by moving the sliding carriage further.
  • the invention also provides that the front pair of rollers of the slide carriage at the end of the ramps can be rotated in recesses of pivoting parts in the support frame, while the rear pair of rollers can be pivoted out through a gap that remains free between the guides.
  • the invention also provides that a protruding pouring sleeve adjoins the closure plate, which is preferably oriented either perpendicular to the direction of displacement of the closure plate or at an angle of, for example, 30 ° to the perpendicular to this direction of displacement.
  • This pouring sleeve can serve as a guide for a drill or lance for opening or burning out the tapping hole before or after the slag is poured off. It also helps to prevent the slag from splashing, especially at the start of tapping. In addition, with the appropriate shape, it can be used to guide the slag flow in a targeted manner towards a channel.
  • the sliding surface of the furnace is formed by a sleeve block made of copper or refractory material.
  • a sleeve block made of copper or refractory material.
  • Such a block can also easily be installed in the tap hole area of the furnace lining, with or without cooling, such as, for example, water, air, nitrogen, ionic liquids or the like.
  • the slide closure 10 shown serves to pour slag through a tap hole 1 of a partially shown metallurgical vessel 2 which is provided with a further spout, not shown in detail, for pouring off a molten metal.
  • a metallurgical vessel is particularly suitable for pouring non-ferrous metals such as copper or ferro-alloys, but it could also be used in converters, electric furnaces or the like, in which molten steel and slag are poured off.
  • the slide closure 10 consists essentially of a slide housing 3, which can be fastened to the vessel 2, with a support frame 4 and a slide carriage 5 for the exchangeable reception of a closure plate 6.
  • the latter can be moved in the support frame 4 by means of a hydraulic cylinder 13 that can be coupled to it, the stroke of which is between a Open and a closed position is specified.
  • the support frame 4 is provided with a hollow profile-shaped cross section on its four sides.
  • a protruding pouring sleeve 16 adjoins the closure plate 6, which, together with the tapping hole 1, runs at an angle of 30 ° to the perpendicular to the direction of displacement of the closure plate 6.
  • its upper side wall, on which the sliding closure 10 is mounted with its base plate 8 is also shaped outwards at an angle of 30 °.
  • the tapping hole 1 is therefore oriented in such a way that it runs approximately horizontally in this upright furnace position.
  • the sliding closure 10 has only this displaceable closure plate 6 without one or more further stationary closure plates.
  • This closure plate 6 can be pushed directly onto a sliding surface 7 of a sleeve block 9 extending around the tapping hole 1 in the vessel 2, this sleeve block 9 being made of copper and / or a refractory material. In principle, it could also be made in several layers or in several parts or the like.
  • the closure plate 6 can be provided with an exchangeable insert made of metal, graphite or ceramic material in the area of the through hole.
  • the sleeve block 9, the closure plate 6 and / or also the pouring sleeve 16 can be made of an inexpensive metal material such as steel, copper or the like.
  • the slide carriage 5 has two rollers 14a, 14b arranged laterally in pairs as sliding elements, which run along guides 15a, 15b of the support frame 4, which can be braced on the slide housing 3 by bracing members 11, and thus evenly transmit the pressing force of the bracing members 11 onto the carriage 5 and the closure plate 6 .
  • the sliding elements could be designed as sliding shoes or, conversely, the guides in the slide carriage and the sliding elements in the frame 4.
  • These guides 15a, 15b are designed at their ends as ramps 19a, 19b, the inclination of which is dimensioned such that they are lowered there by a height amount that relaxes the spring bolts 10.
  • pivoting device 20 By means of a pivoting device 20, the slide carriage 5 with the closure plate 6 can be pivoted out of or into the support frame 4 after it has been shifted outside the effective area.
  • This pivoting device 20 is composed of pivoting parts 23 which can be tilted on both sides in the support frame 4 and which are connected to the front Corresponding roller pair 14a. These two pivot parts 23 can each be rotated in two positions.
  • pivoting parts 23 of the pivoting device 20 form, on the one hand, a stroke limiting stop 23a at the end of one of the guides 15a, so that the slide carriage 5 cannot be released from the bracing force in the operational state.
  • the slide lock 30 according to Fig. 4 is essentially the same as the one after FIGS. 1 to 3 designed and therefore only the differences are shown below.
  • the same reference numerals are used for the same components as in the case of the sliding closure 10 explained in FIG Fig. 1 used.
  • this slide closure 30 The main difference of this slide closure 30 is that the tap hole 31 and with it the pouring sleeve 36 are aligned with their axes perpendicular to the direction of displacement of the closure plate 6. This results in a somewhat simpler construction with this sliding lock than with the one after Fig. 1 .
  • the sleeve block 32 is indicated on the inside of its wall, which extends up to the sliding surface 7 which is in contact with the closure plate 6. This in turn provides a simple design for the tight connection of the vessel to the closure plate 6.
  • the sliding closure according to the invention has the advantage over conventional ones with a fixed and a movable closure plate that it contains fewer components and is therefore very easy to maintain.
  • the embodiment described relates to a slide closure which is used for pouring off slag.
  • the invention can also easily be used to pour metal melts.
  • the sleeve block, the closure plate and / or the pouring sleeve could in principle also be made of a refractory material.
  • the sleeve block could also be equipped with an insert on its sliding surface which is in contact with the closure plate.
