Definitions

  • the invention relates to an arrangement for lining a chapel of a blast furnace.
  • molded components are used from refractory material.
  • a first prefabricated mold component and at least one further prefabricated mold component is to be used.
  • the mold components are positively interlocking used in the chapel.
  • the first mold component and the further mold components engage in one another via a vertically extending tongue and groove pairing.
  • the tongue and groove pairing in the sense of the invention can be any type of undercut, which translates transversely to the Center axis of the chapel counteracts. It must be ensured that the mold components are not only supported by the furnace internal pressure on the Kapellenwandung, but also mutually interlocked.
  • the mutually facing contact surfaces of the molded components may have at least one inclined surface extending at an angle to the central plateau of the chapel and in the direction of the tongue and groove pairing. This inclined surface preferably extends from the front of the mold components arranged on the outside of the oven to approximately into a central depth region of the mold components.
  • the positive connection between the mold components can be canceled by the manual breaking away of the mouth-side undercut of this first inclined surface, so that they can be broken out of the chapel without much effort.
  • two inclined surfaces of opposite pitch are provided, which are optionally connected to each other via a standing at an angle to the inclined surfaces transverse surface.
  • the mold component can be broken out of overcoming the taper of the chapel from this.
  • the degree of slopes of the inclined surfaces can be different.
  • the remaining between the mold components and the Kapellenwandung open spaces are poured with refractory material.
  • the aus manoeuvreenden free spaces can be relatively narrow depending on the dimensional accuracy of the mold components. They may have a width of less than 10 mm, in particular from 4 mm to 6 mm.
  • a groove facing the Kapellenwandung may additionally be provided in the mold blocks, which increases this free space. Over the cross-section of the groove ensures that even refractory mass lower flowability is completely disposed between Kapellenwandung and the mold components.
  • the moldings should line the chapel at least two thirds of the height of the plin. At this height there is enough free space to stack shaped components with a height that is about one quarter of the chapel height, one above the other. Become a large mold component, which extends over about two-thirds to three quarters of the height of the chapel and also uses three smaller stackable mold components that are used in the tongue and groove mating from above, then a total of only four mold components required to line the chapel to a large extent. The remaining space, which is necessary for mounting the mold components, is enclosed on the inside and outside and potted with refractory material.
  • FIG. 1 shows a chapel K in which a total of four molded components 1, 2, 3, 4 are inserted.
  • the selected numbering of the reference numerals corresponds to the order in which the mold components 1, 2, 3, 4 are inserted into the chapel K.
  • first the first and largest mold component 1 is used, which in this embodiment extends over approximately two thirds of the total height HG of the chapel K and occupies approximately 70% of the width of the chapel K. That essentially cuboid first mold component 1 is in the image plane to the right of the second to fourth mold component 2, 3, 4 adjacent.
  • These smaller mold components 2, 3, 4 have substantially the same height H, wherein the stack height SH of the three stacked second to fourth mold components 2, 3, 4 corresponds to the height of the first mold component 1.
  • the stitch hole 5 can be seen in its lower third.
  • a groove 9 which surrounds all the mold components 1-4 used outside.
  • this groove 9 is poured after the positioning of the molded components 1-4 refractory material ( Figure 2).
  • the free space 8 above the mold components 1, 2, 3, 4 is poured with refractory material.
  • the refractory material also passes on the side facing the furnace interior l, so to speak behind the mold components 1, 2, 3, 4.
  • a gap S facing the lateral Kapellenwandungen KW is also filled with refractory material with a width of about 5 mm.
  • the groove 9 has been dispensed with on the identically designed third and fourth mold components 3, 4 on the upper side.
  • the chapel K as a whole has a conical shape, its cross-section tapering outwardly from the interior of the oven I.
  • the arrangement according to the invention is supported against the Kapellenwandung KW and can withstand the outgoing from the furnace interior I pressure.
  • the inclined surface 12 is in this embodiment at an angle of 70 ° to the front side 13 and Angle W of 20 ° to the midplane MHE.
  • a transverse surface 14 which extends at right angles to the central plane MHE of the chapel K or the mold components 1, 2, 3, 4.
  • the tap hole 5 which is located with a broken line.
  • the transverse surface 14 jumps in the image plane to the right as far back as the inclined surface 12 engages in the groove 15 of the first mold component 1.
  • Adjoining this transverse surface 14 is a contact surface 16 extending up to the rear side R of the molded components 1, 3, which in this exemplary embodiment extends parallel to the mid-plane MHE.
  • the undercut 17 formed on the first mold component 1 is broken open manually or by means of an excavator. Then the smaller of the shaped components can be pulled out of the chapel K to the front. When all the small mold members 2, 3, 4 have been removed, the first mold member 1 may also be broken out. In this way 60% to 80% of the chapel volume can be broken out with relatively little effort and time.
  • the rear contact surface 16a between the first and the further molded components 1, 2, 3, 4 is likewise designed as an inclined surface.
  • the rear inclined surface 16a extends at least parallel to the Kapellenwandung facing outer surface 18 of the smaller mold members 2, 3, 4, which rest against the Kapellenwandept.
  • the smaller of the shaped components 2, 3, 4 preferably taper in the direction of the interior of the oven, so that the breaking of the smaller shaped components 2, 3, 4 does not lead to clamps on the wall of the chapel. For simplicity, was omitted in Figure 3 on the representation of the circumferential groove for the introduction of refractory material.
