Definitions

  • the invention relates to a firing pad for firing tile moldings, with the various roof tile moldings are transported through a furnace and which is designed as a loadable for a lying roof tile assembly, gas-flowable grate of a refractory material and spaced side by side extending support rods and through this a variety of having side by side or in succession roof tile receiving stations, wherein individual support rods are combined to form a support rod group.
  • roof tiles which in the context of this patent application both roof tiles (roofing) as ridge tiles, Trautziegel, fan brick, Ortzieziegel (with internal or external flap) longitudinal roof tiles, transverse roof tiles or the like.
  • firing documents which support the roof tile moldings cross-sectionally on the product specifically form and measure trainees reference points (system or support surfaces, overlaps and the like.)
  • Such form-fitting that burning at higher temperatures (near the softening point of Clay material) is possible and still a disadvantageous deformation is prevented.
  • H-cassettes made of refractory material are used for the roof tile fire in practice, whose H-web supports the roof tile base.
  • Such H-cassettes are designed as monocassettes - see trade magazine BRICK INDUSTRY INTERNATIONAL ZI 9/97, page 581-582 - and require in particular in the accessory production a variety of different cassettes and thus high investment costs for the cassette provision.
  • the monocassette handling regarding loading and unloading is time consuming and expensive.
  • An H-cassette for burning roof tiles, with which various roof tile moldings are transportable through an oven, where it is itself formed as a gas-permeable grate made of refractory material is known from DE-B-40 12 316.
  • a grate for receiving tile moldings which has side by side and successively provided support rods for receiving roof tile moldings. Between the individual support bars are provided gaps. These support rods are arranged horizontally and each have a substantially corrugated or wavy edge structuring, so that at the respective upper regions of this corrugation or wavy structures height support surfaces are formed, however, have an identical height dimension for each support rod, so that adjacent support surfaces also an identical Have high extension.
  • support rods formed differently is the high extent of the support surfaces in turn identical to the support surfaces of the adjacent support rods.
  • Each longitudinal dimension of the corrugation or the shaft of the structure is designed differently. Thus, special forms of a roof tile molding are not properly support.
  • the invention provides a firing pad according to the patent claim 1.
  • the firing pads according to the invention cause a significant reduction in investment costs and operating costs of a tile factory with production of many differently shaped tile and / or accessory tiles and thereby ensures even when burning in cross-section a large height having moldings a form harnesse, d. H. an adverse deformation in the firing process preventing support of the roof tile back using firewood carriers with little aufloomender mass.
  • the firing pads have a width of up to about 3.5 m. This is economically feasible in the current state of material technology through refractory profiles, such as pipes, based on silicon carbide. It means that in so-called narrow kiln on the tunnel width uses a single large-scale firing pad for single-layer roof tile support and two firing pads are arranged side by side with wide kiln. Of course, in a wide tunnel kiln, three firing pads may be provided side by side, if a so-called "deteriorated version" is accepted.
  • the invention can be provided both in systems with the combustion chamber floor insulation forming tunnel kiln cars as well as in systems with within a trained in cross-section all around with stationary insulation movable and / or movable fuel racks.
  • the one-day flat firing in the so-called quick firing process is preferred and the firing documents of the invention remain on the tunnel kiln car, ie they are not removed as before in the systems with monocassettes with the fired roof tiles.
  • the plant according to the invention thus has a kiln car direct loading. This results in a considerable simplification in the system concept as well as a favorable reduction of investment costs.
  • tunnel kiln cars are used for transport through the tunnel kiln, two firing documents according to the invention are arranged one behind the other on the carriage length.
  • the firing documents according to the invention can also multi-day walk through the combustion chamber - this may be useful especially in furnace-tunnel kiln systems.
  • a design is preferred in which two transverse to the transport direction cross members or support beams (which preferably have a weight-saving profile, in particular formed by a tube), the individual support rods are arranged (store).
  • the support rod length can accommodate up to five roof tiles (moldings) in longitudinally aligned arrangement - particularly preferred is an education for the inclusion of four roof tiles (moldings).
  • a further embodiment provides to form the firing pads with shorter support rods and to provide at least one additional inner / middle support beam between the two outer transverse support beams, whereupon support two supporting rods in particular aligned one behind the other.
  • the individual support rods are designed to accommodate at least one roof tile length.
  • Another variant is designed for only one series of moldings - thus arranged for only one roof tile length support bars on or on two transverse support beams (bodies) are arranged.
  • this single-row design can also be easily modified for a tilt trim.
  • additional tilting means (to be provided on the firing pad or the transporting means receiving the same) and abutments for preventing the firing-down of the kiln are to be arranged.
  • the firing pads are each designed so that the individual roof tile moldings can be placed rotated by 180 °.
  • a firing tile 1 according to the invention for roof tile firing is designed to accommodate a multiplicity of different roof tile moldings 2 ', 2 "and is made of refractory profiles as a" firing grid.
  • the so-called surface tiles and accessory tiles can be supported in a form-fitting manner Rust surface in Reihan arrangement so-called surface tile receiving places (for usual, ie "normal” surface tiles as well as for these normal surface bricks of the support requirements similar or their support planes using accessory bricks) available, those with "N”
  • a so-called special brick receiving space is formed between two surface tile receiving spaces N (for accessory tiles provided in cross section in the side edge area with a high lobe or web, for example, paving tiles with external lapping, ridge tiles and the like), which is provided with " S "is marked.
  • the locations designated by "N” and “S” are formed by at least three, preferably four support rods 3-6, which in turn are arranged on support beams / base body 7.
  • the support rods 3, 4, 5 and 6 as well as the supporting beams / base bodies 7 which underlie them are preferably made of a refractory material based on silicon carbide - SiSiC is particularly advantageous and preferred.
  • the pos. 3-7 are advantageously made of square cross-section tube - but it can also end pipe cross-sections or even angle or T-profiles for Get used.
  • the support beams or base 7 are supported in the illustrated embodiment of supports 8, which are either part of a kiln car or are arranged on another of the promotion by a kiln serving transport.
  • the burning pad 1 according to the invention can also be used for so-called.
  • the support beams or base bodies 7 do not run transversely (as can be seen from the drawings) to the transport direction T, but in the transport direction, ie. the grate is turned or used rotated by 90 °).
  • the support rods 3-6 formed by prismatic profiles are formed on the formling-bearing upper side with recesses 9 for transverse rib and / or brim reception. It may be advantageous to form and / or arrange the recesses 9 in such a way that the roof tile moldings 2 'can be placed turned by 180 ° - i. in right-hand version and left-hand version.
  • the support rods 3-6 are each combined in groups "G" in such a way that each support rod group G forms a series of surface tile receiving sites N.
  • the support rod tops are on at least three levels, which are designated A, B and C.
  • outer support rods 3 and 6 are each with their tops at the same height, resulting in between two adjacent support bar groups G then a special tile receiving space S for tile moldings 2 '' results. Between adjacent support bar groups G there is a gap numbered 10.
  • a support level approximately lower than the so-called "shard strength" is provided. It can be this support levels A and C according to the drawings of two closely spaced support rods 5, 6 or from a single, graduated in cross-section accordingly, ie formed in two stages, running support bar formed.
  • the support bar 4 lying in the middle section in the group cross-section has the lowest support plane 3.
  • an additional support rod 11 is provided in addition to the outer support rod 6 of a support rod group.
  • each firing pad 1 lie with both ends on the support beams / base bodies 7 and it is at one end a displaceable connection - a so-called.
