Definitions
- the invention relates to a holder for a ceramic car body for holding blanks made of ceramic material to be burned, especially for burning roof tile blanks, according to the generic term of Claim 1.
- Roof tiles are used for firing after drying ceramic car bodies positioned on kiln cars and then enter one longer oven journey.
- ceramic car bodies also as Called kiln furniture
- the side view in are substantially H-shaped, with the central web to the respective shape of the Blank for appropriate support is adapted from this.
- These H-cassettes can be stacked horizontally on top of each other with the blanks taken from them. Apart from the fact that these H-cassettes despite their honeycomb structure Stability reasons form a significant mass, in addition to the Roof tile blanks are heated, depending on the shape of the blank, other H cassettes to use.
- the object of the invention is a holder for a ceramic To create car body according to the preamble of claim 1, its mass is significantly reduced compared to the absorbed mass to be burned and adaptable to the shape of blanks to be burned in a simple manner is.
- brackets are not only of simple construction, but also allow a substantial reduction in mass due to the hollow profile lattice structure and the high strength of the material used, so that Ratio of mass to be heated to burning is considerably cheaper. This is particularly favored by the use of ceramic Light profiles, i.e. Profiles of low wall thickness and thus low mass.
- the holders are preferably suitable for essentially plate-shaped ceramic blanks, in particular roof tile blanks. All parts of the Ceramic car bodies expediently consist of silicon-infiltrated, reaction-bonded silicon carbide, silicon nitride bonded silicon carbide or recrystallized silicon carbide. On Such ceramic car body is also suitable for Quick fire fighting. By appropriate insertion of supports use the holder for different blank shapes without whose mass would have to be increased significantly.
- the ceramic car body shown comprises over a platform a furnace car, not shown, arranged a series of elevated, parallel, horizontally arranged bars 1, on which one A large number of brackets 2 at approximately the same distance above supports 3 in one predetermined inclination to the horizontal and held parallel to each other are arranged.
- the beams 1 and the supports 3 are in the form of ceramic Light profiles, in particular box-shaped hollow or U profiles. Furthermore, the beams 1 are regularly spaced in the longitudinal direction, insertion holes and notches for the supports 3 or brackets 2 provided.
- the holder 2 consists of a flat, interconnected, in particular hollow webs 4 formed lattice structure from a Silicon carbide material with a variety of in the illustrated embodiment openings 5 and arranged in two rows along each longitudinal edge further openings 6 in the central area.
- the openings 5 and 6 have in illustrated embodiment each the same size.
- the openings 5 and optionally 6 are used to hold positionally fixable positions Support pieces 7 provided in the openings 5 and 6 respectively Support points can be used for a specific blank shape.
- the support pieces 7 are expediently hollow and consist of one in the Opening 5 or 6 insertable foot 7a, a support plate 7b for resting on the Bracket 2 and a support piece 7c extending upward therefrom.
- the scope of the bracket 2 and the number and arrangement of openings 5, 6 can be optimized according to the shapes of the blanks to be burned to be heated with minimal mass in addition to the mass to be burned Get by mass.
- the openings 5, 6 can be any suitable Have shape and do not have to be square or rectangular, as shown his.
- the support pieces 7 on two opposite sides in the lower region of the foot 7a one each have the opening 5 or 6 feasible, lateral extension 8, while the opposite webs 4 delimiting the openings 5
- the extensions 8 By inserting the extensions 8 reach the underside of the holder 2 and the extensions 8 are moved to fix the position relative to the plane of the bracket 2, so that the extensions 8 from the area of the push-through recesses 9 under the Appropriate webs 4 arrive and thus secure the respective support piece 7, whether the bracket 2 is used in a horizontal or inclined position.
- the support pieces 7 can also be permitted so that after their insertion into an opening 5 or 6 fixed in position by turning be by their extensions 8 by rotating from the area of Push-through recesses 9 come out.
- the push-through recesses 9 can also through corresponding elongated openings 5, such as the Openings 6 are formed.
- brackets 2 stacked horizontally on top of each other can be provided in openings 5 and / or 6 of the lattice structure Inserts corresponding to the support pieces 7 to the horizontal Stacking brackets 2 to be arranged, the inserts expediently also like the support pieces 7 a foot, a Have platen and a support piece and in their position about Extensions are fixable.
- bracket 2 Expediently on one side of the plane of the lattice structure essentially vertically projecting support projections 10 for the blank are provided, the inclined arrangement of the bracket 2 to the lower Support the blank.
- the bracket 2 can in particular the two support projections 10 together with one Use as a three-point support for another bracket 2.
- the bars 1 can also be inclined sideways, for example by lateral projections formed guides for the corresponding beam 1 have encompassing legs of the holder 2, with a bar 1 alone a plurality of inclined brackets 2 arranged one behind the other can accommodate so that the supports 3 and the notches on the top the bar 1 can be omitted.
