Definitions

  • the invention relates to a pouring device for slide systems, the for example in steel ladles, with an im essentially cylindrical sheet metal jacket that has a fire-resistant inside Has liner, and a fastening device with which the Pouring device is attached to a slide plate, the sheet metal jacket and the fastening device are integrally connected to one another, the Sheet metal jacket and the fireproof lining in the area of Fastening device have a constant wall thickness.
  • a slide system in the pouring area of a steel ladle is disclosed in FR-A 2 565 859.
  • the pouring device that described in FR-A 2 565 859 Systems includes a completely undisguised tubular pouring element made of refractory material. This element not provided with a metal jacket has a cam ring in the lower third or at least cams arranged in a ring.
  • the slide system has an upper spring-loaded plate on which a sleeve section is arranged.
  • the intermediate sleeve with the upper sleeve portion is screwed and on the opposite, lower end face has a ring which as System for the cam ring or the ring-shaped arrangement Serves cams of the element. Because the element consists exclusively of refractory material No forces are transmitted via the cam ring or cams become.
  • the so-called Screwed key which one Counter bearing mouthpiece leads to the element which then between the upper slide plate and the Counter bearing mouthpiece jammed and thus as a pouring system is fixed.
  • the object of the invention is to avoid the aforementioned disadvantages by creating a pouring device which can be quickly and easily attached to a slide plate and which, even after repeated use, has a high level of security against steel breakthrough.
  • a simple attachment is achieved in that the fastening device has a plurality of cams, which are essentially rectangular and on the Sheet metal jacket are attached.
  • a particularly simple one Attachment can be achieved in that the cams have a collar on the sheet metal jacket is present and connected to it.
  • the sheet metal jacket has openings into which the Cams are inserted from the inside and with the collar lie against the inner wall of the sheet metal jacket.
  • the assembly of the cams very easy, because the cams are only in the previously punched out Openings of the sheet metal jacket are inserted and then be connected to the sheet metal jacket. Due to the shape of the cams and the openings as well as the collar arranged on the cams is such a mechanical production of the pouring device possible.
  • the cams are preferably regular Distance attached to the sheet metal jacket.
  • a special one advantageous embodiment results when three cams each attached to the sheet metal jacket offset by 120 ° are. This is an inexpensive manufacture of Pouring device possible, which has sufficient stability the pouring device on the slide plate guaranteed and also with sufficient stability in the backdrop is feasible.
  • the sheet metal jacket has several cams, the point or are axisymmetric and in openings of the sheet metal jacket are attached below the openings for the cams for fastening the pouring device are arranged.
  • a tool is attached with the help of which the pouring device in the arranged on the slide plate Back in or out of the backdrop can be.
  • This tool can, for example a manually or electrohydraulically driven one Be pliers.
  • Pouring device are the cams for the Approach of a tool circular.
  • the cams are preferably spot welded attached to the sheet metal jacket. This is ensures that the cams with sufficient Strength associated with dam sheet metal jacket and that due to the welding process, there is no great delay in the Part of very thin-walled sheet occurs.
  • the sheet metal jacket on its facing the slide plate End has a ring groove.
  • This ring groove which for example is designed as an inner bead, serves to reinforce of the sheet metal jacket and enables one evenly applied to the inner surface of the sheet metal body Refractory lining.
  • the sheet metal jacket on its lower end at least one around the sheet metal jacket circumferential bulge, preferably one Has outer bead. With this bulge Heat transfer between the sheet metal jacket and the pouring molten steel in this area arranged connector interrupted.
  • An essentially cylindrical sheet metal jacket 1 points to a slide plate, not shown facing end 5 an annular groove 14. On the opposite End 15 of the sheet metal jacket 1, which is conical, two outer beads 16 are arranged.
  • the sheet metal jacket 1 has one on its inside fireproof lining 2.
  • End 5 of the sheet metal jacket 1 are in regularly Clearances openings 3 punched in are substantially rectangular, the edge 5 facing the end 6 of the opening 3 below einam spitzan angle to the central axis 7 is arranged.
  • the three remaining edges of the opening 3 are either arranged parallel or at right angles to the central axis 7.
  • each opening 3 is one round opening 8 punched in the sheet metal jacket 1. All in all are in the sheet metal jacket 1 three essentially rectangular openings 3 and three round openings 8 punched, each offset by 120 ° in the sheet metal jacket 1 are arranged.
  • each substantially rectangular opening 3 is one Cam 4 used, the one corresponding to the opening Has shape and a circumferential collar 11 has.
  • the collar 11 lies after the mounting of the cam 4 on the inner wall 9 of the sheet metal jacket 1.
  • Collar 11 welded to dam sheet metal jacket 1. The The welding process is carried out by means of spot welding.
  • Cams 10 are also in the round openings 8 used, which also have a collar 11 and by means of spot welding on the inner wall 9 of the sheet metal jacket 1 are attached.
  • the pouring device for steel ladles according to the invention is produced in the following manner: In the essentially cylindrical sheet metal jacket 1, the three essentially rectangular openings 3, each offset by 120 °, and the three, each arranged under the rectangular openings 3, are punched at round openings 8. Then the cams 4, 10, which are deep-drawn from a sheet, are inserted into the corresponding openings 3, 8 from the inside, so that the collar 11 arranged on the cams 4, 10 bears against the inner wall 9 of the sheet metal jacket 1. The cams 4, 10 are then attached to the sheet metal jacket by means of spot welding processes.
  • the pouring device in the Link guide arranged on a slide plate used such that the cams 4 with the on the underside of the cam 13 arranged inclined surface 12 in FIG Place the slide plate against the backdrop.
  • the pouring device is rotated, until the pouring device is firmly in the slide plate sits.
  • the pouring device After completion of the pouring process, the pouring device can in a corresponding manner from the slide plate be removed. By their design is it is possible to use the pouring device several times.
  • the invention is not based on the illustrated embodiment limited. There are several changes and variations possible without representing the Rahman Leaving invention.
  • the cams 4 and 10 have a shape other than that in FIGS Figures shown. Fernar is also possible, more as three cams 4 offset by 120 ° on dam Arrange sheet metal jacket 1.
