Definitions

  • the invention relates to a refractory lining for the lid of metallurgical vessels, in particular for a heat distributor used in continuous casting plants, the inside of which is lined with fireproof material and provided with burner openings.
  • lids have either a refractory concrete layer on the fire side or a fire-resistant cladding which can be bricked up or can be constructed like a fire blanket.
  • a refractory concrete layer on the fire side or a fire-resistant cladding which can be bricked up or can be constructed like a fire blanket.
  • the object of the present invention is to facilitate handling during repairs and new deliveries with improved operating behavior and increased thermal insulation by means of an improved structure and arrangement of the refractory lining in the lid.
  • a heat shield which can be removed from the cover plate by means of supporting members and is movably held in plan is arranged in front of an insulation by inserting an elastic peripheral seal.
  • the lining compensates for thermal stresses excellently and is extremely thermally insulated.
  • the invention provides a support plate clad on the fire side with refractory material with support pins which are mounted so as to be movable in a plane in the base, penetrate the insulation and are suspended on the cover plate, the pins being held with a collar in a tolerance chamber of the base.
  • This construction gives the heat shield sufficient plan mobility with simple constructional means and creates optimal conditions for handling, especially when the supporting bolts are advantageously detachably suspended from the sleeve of the cover plate and pipe sockets are provided on this plate, which limit recesses in the insulation and the arrangement of supporting bolts and base surround.
  • the refractory cover lining is made of ceramic fiber packs, while the heat shield has a refractory concrete layer anchored to the support plate with the interposition of a ceramic fiber mat by pins.
  • the refractory concrete layer can be removed from the support plate together with the fiber mat if necessary.
  • burner stones arranged on the heat shield engage in collars fastened around the burner openings on the cover plate and lined with ceramic fiber material.
  • the one made Basic assignment of the burner blocks to the heat shield contributes to further simplifying the maintenance of the cover, especially if preferably each burner block is detachably held at least at two opposite locations on the circumferential surface by a holding device arranged on the support plate in the refractory concrete layer, so that after the refractory concrete layer is broken open in the said places each burner block on the installed or removed heat shield can be replaced.
  • refractory protective sleeves are provided on the heat shield, which surround these supports in the case of a cover with support supports provided in an emptying gap.
  • the heat shield is divided longitudinally into shield sections with their own peripheral seals. This is a particularly advantageous embodiment because the individual sections of the heat shield can be replaced independently of one another and it is possible to adapt the size dimensions of the sections to existing transport means.
  • circumferential frames enclosing the refractory concrete layer are provided on the support plate of the heat shield or the shield sections, on which sealing cords made of ceramic fiber are inserted, which results in a simple but effective sealing.
  • V denotes a distributor, which is used to feed continuous casting molds with molten steel and is provided on one long side with a pouring core 1, also an intermediate container or tundish, which has a metallic jacket 2 and a refractory lining 3. Furthermore, a row of spouts 4 with inlet connections 5 and external slide closures 6 are provided in the center of the distributor base, by means of which the melt discharge to the individual molds of the continuous casting plant can be regulated through pouring tubes (not shown).
  • the distributor V is covered with a cover W lined with insulating and refractory materials.
  • This has a mounting frame 7 and a cover plate 10 provided with burner openings 8 and a pouring opening 9, on which a profile rail 12 including and cooling a circumferential cooling 11 is provided.
  • the cover W has insulation 13, which is protected by a heat shield H, which consists of a heat-resistant support plate 15 clad on the fire side with a fire-concrete layer 14 and is held detachably on the cover plate 10 by means of support bolts 16 attached thereto.
  • the insulation penetrating burner blocks 18 are arranged on the heat shield H, whereas an opening lining 19 made of unshaped refractory material is provided at the pouring opening 9 and extends over the pouring core 1.
  • the cover W has on the long side, on which the pouring core 1 is located, an emptying gap 20 with refractory-clad cover supports 21 resting on the distributor V, around which the board surface 22 on which the cover W is seated has a refractory protective layer 23 wearing.
  • stopper 25 which can be clamped onto the distributor by means of hydraulic means (not shown) and which can be clamped onto the distributor, can be inserted into the burner blocks 18 to close the burner openings 8.
  • the gap 20 serves to free the distributor V parked on the parking space outside the continuous casting installation by tilting about its longitudinal axis from residual melt containing predominantly slag in order to avoid freezing in the ceramic of the slide closures 6. Also on the parking space, the distributor V is heated before it is used in the continuous casting installation, for which purpose 8 burners are inserted into the burner openings which are otherwise closed by the plugs 25. In addition, another cover with 8 burners permanently attached to the burner openings is available as part of the management of a continuous caster. If emptying is no longer guaranteed - the dwell time is too long - you have to tilt back to the starting position and release the lock. Now a "second cover" in the waiting position is put on and hydraulically clamped again.
  • This "second lid” is the same as the other, with the exception of the high-performance burners located there.
  • These high-performance burners are arranged in such a way that they are located when the cover is placed on the distributor channel, just above the tundish sliding locks (slide lock heating). These six high-performance burners are able to heat the interior to over 1500 ° C and liquefy the residual steel cooled there.
  • a sealing braid 26 made of ceramic fiber material is introduced into the gap 20 and is only removed again before the distributor V is emptied.
  • FIGS. 6 to 12. 6 to 9 The more detailed design of the refractory lining of the cover W can be seen in FIGS. 6 to 12. 6 to 9, the insulation 13 composed of ceramic fiber packs 30 is attached to the inside of the cover plate 10, which has been tried and tested with profiled rails 12, leaving pipe stubs 31 attached to the cover plate 10 free, through which the support bolts 16 of the removable heat shield H engage for wedging plug sleeves 32 fastened to the cover plate 10.
  • the perforated support plate 15 of the heat shield H has hollow-cylindrical bases 34 on the upper side which fit into the pipe socket 31 and in which the support bolts 16 are movably mounted in a plane plane.
  • the support plate 15 is equipped with expansion pins 35 in a checkerboard manner, for holding a ceramic fiber mat 36, an oil paper or plastic film 37 and the refractory concrete layer 14, the positions 36, 37 and 14 being fitted by a peripheral frame 39 of the plate 15.
  • the heat shield H according to FIG. 8 is subdivided lengthwise into individually interchangeable and interchangeable shield sections 40, which in FIG.
  • each support bolt 16 is supported by a collar 42 in a tolerance chamber 44 of the base 34, which has cleaning openings 43 and whose cover plate 45 is welded when the support bolt 16 is inserted.
  • bases 34 are shortened by the gap width in the area of the gap 20. There, in the gap area, the thickness of the insulation 13 is reduced accordingly and the mounting frame 7 of the Cover W replaced by supports 21 protected with refractory protective sleeves 47 (see FIG. 6).
  • the sleeves 47 which are advantageously prefabricated from refractory concrete, are part of the heat shield H or the shield sections 40 and, when the cover W is placed on the board surface 22 of the distributor V, engage in recesses 48 in the protective layer 23 covering this surface in the region of the gap 2, with a seal being provided ceramic fiber cord 49.
  • the opening lining 19 similar to the heat shield H, consists of a fiber mat 36 of a film 37 and of refractory concrete 14, which also includes the filling side of the pouring opening 9.
  • each burner block 18 can be closed with the plug 25 mentioned at the beginning, which, according to FIG. 12, consists of a reinforcement pot 67 carrying the handling shaft 24 and an outside refractory lining. Based on the heat shield H on expansion pins 35 of the reinforcement pot 56, this is formed by a ceramic fiber mat 36, a film 37 and a refractory concrete layer 38.
  • the described cover W with its emptying gap 20 is suitable for special operating conditions.
  • the lining according to the invention applies to lids which have no lateral emptying gap.
  • the lining according to the invention also does justice to metallurgical vessels which are not used in continuous casting plants but are subject to similar operating conditions.
