Definitions

  • the invention relates to a stackable firing support for moldings for use in a kiln with at least two feet and a support frame connecting them to receive preferably ceramic moldings.
  • a stackable firing support as a firing aid for firing ceramic moldings is known from EP-O 212 598 A1. It has an essentially U-shaped cross section and consists of a closed, continuous support plate for moldings and feet. Heating and cooling the firing pads places high demands on their resistance to temperature changes. They must also be structurally stable. Furthermore, a firing pad should also be suitable for holding bulky moldings. The distance between stacked firing pads and thus the capacity for bulky moldings is determined by the length of the feet in stackable firing pads. For reasons of thermal resilience and static strength, their expansion is limited. According to EP-O 212 598 A1, the feet only extend in one direction away from the support plate.
  • the molding lies on the firing support plate only in a few points and can be particularly stressful for bulky shapes considerable distance from the burning surface above.
  • the longer extension of the feet required for this affects the thermal shock resistance and the static strength of the firing support. It is true that two such known firing pads can be stacked upside down with their feet facing each other in order to create a higher free space for moldings; however, this way of stacking means that two support plates also follow one another directly, whereby only one plate can actually be used.
  • the invention has for its object to increase the thermal shock resistance and static strength of stackable firing pads.
  • the support frame 1 is arranged in the middle of the firing support.
  • the feet 2 and the support frame 1 thus form an H-shaped cross section, where h and h 'is the distance between the support frame 1 and the foot ends.
  • h and h ' is the distance between the support frame 1 and the foot ends.
  • the frame 1 is formed by upstanding webs 7. In a preferred embodiment, all webs and also the feet have essentially the same width d.
  • the surfaces of the webs 1a, 1b, 1e can be arranged in different planes and serve as contact surfaces for the molding.
  • the webs delimit several frame openings 6 into which bulky parts of molded articles can protrude.
  • Such a frame construction, in particular with the same web width d of the upstanding webs ensures high resistance to temperature changes and mechanical strength. Outbreaks in the webs that inevitably occur during prolonged operation do not necessarily have to impair the functionality and stability of stacked burning documents.
  • the feet 2 have cutouts 3 in the longitudinal direction. This measure increases the mechanical stability of the firing support and ensures good heat convection. Recesses 4 and complementary projections 5 at the foot ends, for example according to the tongue and groove principle, ensure simple and stable stacking of the firing pads.
  • the firing pad can consist of a fireclay material.
  • a preferred material is cordierite.
  • the firing pad can withstand thermal loads of up to approx. 1300 ° C without difficulty and generally goes through the cold-warm-cold cycle in 10 to 20 hours.
  • the temperature load can be periodically or continuously without problems.
  • the dimensions of the firing support are 500 mm in length, 370 mm in width, 180 mm in height from foot end to foot end and the uniform width d of the webs and feet is 20 mm. Other dimensions are possible in a wide range of variations.
  • FIG. 2 Another use of the embodiment according to the invention according to FIG. 1 is shown in FIG. 2:
  • the support surfaces 1a, 1b and 1e of the support frame 1 shown above are arranged in different planes in order to accommodate uneven moldings.
  • the support surfaces on the back of these firing pads are preferably arranged at the same height, so that after turning the firing pad according to FIG. 2 by 180 °, the back of the support frame 1 can be covered with a smooth or profiled fuel plate 8 to a blank , which must lie on the whole surface, to record.
