Definitions

  • the invention relates to a slide closure for the pouring of molten metal containers, consisting of at least partially formed from refractory, metal-sheathed, firmly but releasably arranged in supports and sliding with one another on the bottom and slide plates, the bottom plate being arranged in a receiving device and with its end faces can be clamped approximately in the longitudinal direction between a first end part of the receiving device and a support member which is adjustably mounted in a second opposite end part of the receiving device.
  • Metal-clad floor and slide plates are preferred for slide closures of this type, because they allow the plates to be changed quickly when worn, without, as in earlier times, mortar embedding being necessary.
  • a certain amount of play between the base plate and the opening provided for this purpose in the carrier is required. You try to compensate this game after inserting the base plate by actuating tensioning devices.
  • the devices which have become known so far for receiving and fastening the base plate are in any case complex in several respects and take up a lot of space.
  • the carrier or support frame itself is a complex construction.
  • a slide closure of the type mentioned at the beginning of FR-A 2 332 831 has, as the receiving device, a one-piece and solid frame which surrounds the slide plate on all sides, which is attached to the slide closure carrier and is provided with a tensioning device for receiving and clamping the slide plate.
  • the first end part of the receiving device consists of a strip-shaped spacer which is fixedly attached to an end face of the frame.
  • the support member is optionally designed as a bar or as a pair of sliding blocks that can be placed on slanted corners of the slide plate.
  • the bar or the sliding blocks are adjustable by means of screw bolts for pressing the slide plate onto the opposite spacer and thus for clamping the slide plate. A separate locking of the bolts in the clamped position of the slide plate is not provided.
  • the task is to reduce the effort of slide closures of the type mentioned above and, above all, but not exclusively, to simplify the unit consisting of the base plate and associated carrier with easy interchangeability and secure clamping or fixing of the base plate.
  • the receiving device consists of two jaws, which are fastened at a corresponding distance from one another on the carrier assigned to the base plate, and that a locking device is formed in a first jaw with the adjustably mounted support member, by means of which the base plate can be locked in a position in which it is placed or pressed onto the opposite second jaw, a T-shaped clamping piece being used to bring about the locking. in a transverse to the longitudinal direction of the first jaw, also T-shaped groove and slidably received by means of a screw acting perpendicular to the clamping device, wherein the clamping piece can be pressed against the adjacent end face of the base plate.
  • two jaws lying opposite one another in parallel and spaced apart which are designed in a special way and attached to the carrier, are sufficient to form the receiving device.
  • the base plate is inserted in the position assigned to it with little play between the two jaws and then firmly pressed against the opposite second jaw by moving and pressing the T-shaped clamping piece in the likewise T-shaped groove in the first jaw.
  • the second jaw consequently serves as a precisely fitting stop for one of the end faces of the base plate, while the opposite clamping piece forms the counter stop, which is pressed against the other end face of the base plate, for example by means of a tool.
  • the jaws screwed to the carrier thus form a simple receiving device for the base plate and, by means of the clamping piece and its locking, allow the base plate to be attached to the carrier effectively and reliably. Because the T-shaped clamping piece is securely fixed or secured in the first jaw with the screw acting perpendicular to the clamping direction of the plates.
  • the components used namely the clamp piece and its guide and the two jaws are insensitive, easy to use, and they can not clog.
  • the base plate is preferably essentially rectangular in shape, and its corners should be beveled at least on the end face opposite the locking device in order to bring about three-point clamping, and the jaws should have correspondingly inclined contact surfaces.
  • the clamping piece expediently engages in the center on the end face of the base plate assigned to it, while the two opposite bevelled corners of the overall rectangular base plate receive a secure contact with the correspondingly beveled contact surfaces. In this way, an undesired movement of the base plate is not possible in the longitudinal or transverse direction, which always occupies a precisely defined position in the closure.
  • the jaws themselves are preferably strip-shaped or C-shaped. It is sufficient if the necessary contact surfaces for the end faces of the base plate, a sufficient contact surface with the support and finally sufficient space for the screw fastening used are available.
  • a very essential feature of a further design according to the invention is that the overall arrangement of the jaws and base plate is approximately the same length as the slide plate. This measure also contributes to simplifying the slide closure and reducing the manufacturing outlay. In addition, a considerable part of the refractory material required according to previously known solutions is saved if the base plate, now embedded between the two jaws, is considerably shorter than the slide plate.
  • the sheet metal covering of the slide plate is continued in a sheet metal jacket of the outlet sleeve, which, apart from the pouring opening, is filled with filled refractory or highly heat-resistant material.
  • a base plate 1 and a slide plate 2 are immovably embedded in sheet metal sheaths 3 and 4 and protrude slightly beyond these sheaths so that they do not reach the closing surfaces 15, 16 of the plates.
  • the usual mortar embedding is shown for the slide plate 2 and designated 8 there.
  • the sheet metal casing 4 of the slide plate 2 continues on the underside - with reference to the position of use of the slide closure - in a sheet metal jacket 5 for an outlet sleeve 7, which in the present case is expediently formed from cast but not fired refractory material.
  • the corresponding passage openings of the base and slide plate 1 or 2 as well as the outlet sleeve 7 and an inlet sleeve 6, shown only by dash-dotted lines, are designated by 9a and 9b, 9c and 9d.
  • the slide plate 2 is inserted with its sheet metal casing 4 in a support 13 indicated only by dash-dotted lines and detachably fastened.
  • the base plate 1 with its sheet metal casing 3 is held between two jaws 10, 11, which are fastened to a support 14 indicated only by dash-dotted lines by means of screws, not shown, which reach through bores 12.
  • the C-shaped jaws 10, 11 have inclined contact surfaces 17 which come into engagement with correspondingly bevelled corners 18 of the base plate.
  • FIG. 2 in conjunction with FIG. 5 it can be seen that in the jaw 10 on the right with reference to FIG. 2 there is a T-groove 20 which is open inwards and in the center in relation to the position of use of the closure in the middle a clamping piece 21, which is likewise T-shaped in cross section, is longitudinally adjustable and can be locked in the T-slot 20 by means of a screw 22.
  • the base plate 1 can be easily inserted between the jaws 10, 11, taking into account the manufacturing accuracy of the sheet metal casing 3, a certain amount of play of the order of 2 mm is required for the insertion or replacement of the base plate 1 for the inclined corners to rest on the contact surfaces 17 provided.
  • the base plate 1 After inserting the base plate 1 into the space between the jaws 10, 11, the base plate 1 is pressed against the contact surfaces 17 of the jaw 11 opposite the T-slot 20, and the clamping piece 21 is released in the T-slot 20, to the corresponding one Front side 23 of the base plate 1 brought up and fixed in this position under fixed contact pressure by means of the screw 22 in the T-groove 20.
  • Figures 3 and 4 illustrate the mutual position of the base plate 1 and the slide plate 2 in the closed position and in an intermediate position.
  • the jaw 11 opposite the T-slot in the closed position comes close to the area of the slide plate 2 which is heated by the melt, this does not matter for the clamping of the base plate 1 in the design according to the invention, because the contact surfaces 17 and the associated corners 18 of the base plate 1 lie outside this area.
  • thermal expansion of the jaws can in any event not result in a significant change in the position of the base plate 1, and an inadmissible thermal expansion is avoided by appropriate selection of the steel from which the jaws 10, 11 are made.
  • the locking device by means of clamping piece 21, T-slot 20 and screw 22 for fixing the clamping piece 21 in the T-slot 20 forms a simple and extremely reliable and effective form of a fastening device. It can also be used for setting and locking slide and base plates of a different arrangement and design than that dealt with here.
  • the locking device can replace the eccentric used in the slide closure according to DE-AS 2 821 839, which, as is known, can unintentionally detach due to bumps or the like. This danger does not exist when the locking device is designed in accordance with the invention. It holds the respective plate immovably. This is because the screw presses into the bottom surface of the groove when it is firmly tightened, so that an almost form-locking lock is created. From this it can be seen that it is not absolutely necessary to clamp the respective plate between two jaws in order to make use of a locking device by means of a clamping piece and a T-groove in order to achieve a shock-proof locking for the plate.
