Roller hearth kiln (hereinafter referred to as RHK)
When firing tiles by rapid firing, flat tiles can be directly placed on rollers, conveyed, and fired. However, in the case of irregularly shaped tiles 1 (see Figures 5 and 6) that have special shapes such as corner tiles and baseboards used for outside corners, inside corners, etc., they are transported by being placed on rollers as they are. If so, the specially shaped portion 2 may come into contact with the roller and be deformed or damaged during firing and softening. Therefore, it was placed on a firing tool 3 as shown in FIG. 7, passed through the RHK, and fired. This firing tool 3 is usually manufactured by molding a heat-resistant raw material powder whose main component is one or a mixture of two or more of silicon carbide, silicon nitride, alumina, etc. into a plate shape and firing it at a high temperature. ing. In addition, as special products, cordierite or mullite materials are formed into a plate shape and fired at high temperatures, or a mixture mainly composed of heat-resistant inorganic fibers is simply formed into a plate shape.

However, the firing tool 3 whose main component is one or a mixture of two or more of silicon carbide, silicon nitride, alumina, etc. cannot be said to have excellent heat resistance, and may crack or have a rough surface during firing. The drawback was that it could fall apart and have a short lifespan. That is, it was not preferable as the baking tool 3.

を発生させるという欠点があつた。 In addition, the firing tool 3 made of cordierite or mullite material has a larger heat capacity than the irregularly shaped tile 1 and absorbs the heat of the irregularly shaped tile 1 during firing, so it is necessary to increase the maximum temperature retention time accordingly. It was necessary to change the firing conditions. This is also because the entire top surface 3a of the firing tool 3 is flat, so it comes into close contact with the entire back surface 1b of the irregularly shaped tile, making it difficult for firing heat to be transmitted to the back surface 1b of the tile. However, the flat tile and irregularly shaped tile 1 may be conveyed continuously.
With RHK, it is difficult to change the firing conditions each time, and it takes a huge amount of time to stabilize the firing temperature (obtain a equilibrium state) after changing the firing conditions. In reality, the firing was done under the same firing conditions. For this reason, in the case of the irregularly shaped tile 1, the firing energy was insufficient, resulting in a product defect in which the color of the glaze was different from the expected one. It has the disadvantage of causing uneven burning.

形を発生させるという欠点があつた。 Furthermore, in the firing tool 3 manufactured from a mixture mainly composed of heat-resistant inorganic fibers, the upper surface 3a of the firing tool 3 is vitrified, but the lower surface 3b is less vitrified, and the upper surface 3a side and the lower surface 3b are vitrified to a lesser degree during firing. The degree of thermal expansion and contraction with the lower surface 3b side is greatly different, causing large deformations such as warping, which affects the irregularly shaped tiles 1 in a softened state, causing surface deformations such as warping in the accessory tile 1. There were flaws.

There was a problem that the heat could not be transmitted well to the irregularly shaped tiles 1, and there was a drawback that surface deformations such as uneven burning and warping occurred in the irregularly shaped tiles 1.

The means of the present invention for solving the above problems are as follows:
This is a baking tool for placing and firing irregularly shaped tiles such as corner tiles and baseboards, and the main body of the baking tool is made of a lightweight heat insulating material such as a ceramic fiber molded body. A through-hole is formed, and a coating layer of alumina or the like is formed on the surface of the firing tool body.

As is clear from the embodiments shown in FIGS. 1 to 4, the firing tool 13 made of a lightweight heat insulating material such as a ceramic fiber molded body has a small heat capacity due to the synergistic effect with the through holes 14, which will be described later. Less heat is absorbed from the irregularly shaped tiles 1. Therefore, even when this irregularly shaped tile 1 is quickly fired under the same firing conditions as the flat tile, sufficient firing energy can be obtained, and the tile surface
The glaze (a) performs a predetermined coloring action, and a product with the intended color is obtained. Furthermore, the firing tool 13 is provided with through holes 14 on its upper and lower surfaces 13a and 13b.
Firing heat is transmitted to the back surface 1b of the tile through the through-hole 14, and the firing temperatures on the front and back surfaces 1a and 1b of the tile can be maintained substantially uniform. That is, uneven baking can be prevented. Moreover, since the through hole 14 reduces the mass of the baking tool 13, it greatly contributes to reducing the heat capacity of the baking tool 13. Furthermore, a coating layer 15 of alumina or the like is formed on the surface (the entire surface) of the firing tool 13, which increases its strength and prevents cracks from occurring during firing and the surface from becoming crumbly. .

1 to 4 show an embodiment of the present invention. FIG. 1 is a longitudinal cross-sectional view of the firing tool 13 with the irregularly shaped tiles 1 placed thereon, at a portion that passes through the through-hole 14, FIG. 2 is a longitudinal cross-sectional view of the portion that does not have the through-hole 14, and FIG. FIG. 4 is a perspective view of the firing tool 13 with irregularly shaped tiles 1 placed thereon. As shown in the figure, the firing tool 13 has its upper and lower surfaces 1
It has a through hole 14 drilled across 3a and 13b, and a coating layer 15 made of a heat resistant material such as alumina is formed on the entire surface thereof. The material of the coating layer 15 may also be a heat-resistant inorganic material such as zirconia. The main body of the firing tool 13 is made of a lightweight heat insulating material such as a ceramic fiber molded body having a low specific heat such as alumina or mullite. By molding with a lightweight heat insulating material with low specific heat and providing the through holes 14, the heat capacity of the baking tool 13 can be made extremely small.

成条件で迅速焼成することが可能である。 When the irregularly shaped tile 1 is fired with such a firing tool 13, the firing heat in the furnace is directly transmitted to the back surface 1b of the irregularly shaped tile 1 through the through hole 14 of the firing tool 13, and the front and back surfaces 1a, It is important to make the firing temperature of 1b almost uniform. As mentioned above, the firing tool 13 has a small heat capacity and the amount of heat taken from the back surface 1b of the tile is very small, so that the irregularly shaped tile 1 can be fired with sufficient firing energy, and so-called uneven baking does not occur. In addition, a coating layer 15 made of a heat-resistant material is formed on the entire surface of the firing tool 13, so that it can maintain sufficient strength even if there is a temperature history of repeated exposure to the firing atmosphere, and will not warp in the firing atmosphere. There will be no deformation such as Therefore, surface deformation such as warping is not imparted to the irregularly shaped tiles 1 which are softened during firing. Furthermore, it is possible to extend the service life. As described above, the firing tool 13 of this embodiment has excellent strength and has a structure that allows sufficient firing energy to be applied to the irregularly shaped tiles 1. It is possible to perform rapid firing under the same firing conditions.
次に本実施例による焼成具１３と、第７図乃至
第９図に示す従来の焼成具３とを比較した実験結
果について説明する。 Next, the results of an experiment comparing the baking tool 13 according to this embodiment with the conventional baking tool 3 shown in FIGS. 7 to 9 will be described.
先ず、本考案に係る実施例の技術について説明

繰り返し使用に耐えることが明らかであつた。 First, to explain the technology of the embodiment of the present invention, an alumina coating is applied to the surface of a ceramic fiber molded body whose main components are high-purity alumina and silica, and the bulk density is 0.3 g/cm 3 and the aperture ratio is 40%. The thermal conductivity when manufacturing the baking tool 13 was 0.83×10 -3 Ca1/cms°C. Then, with the firing tool 13, the irregular shaped tiles 1 of 200 mm square are heated to RHK.
The water absorption rate (by immersion in water for 24 hours) of the product fired at 1200° C. (firing temperature: 1200° C., passing time: 45 minutes) was 2.5%. Furthermore, it was clear that the firing tool 13 could withstand repeated use approximately 8 to 10 times.

し使用に耐え得る回数は、およそ１〜２回であつ
た。 On the other hand, when the conventional firing tool 3 is manufactured using a simple porous ceramic material mainly composed of alumina, silica, and magnesium oxide, the bulk density is 2.0 g/cm 3 and the aperture ratio is as expected. However, at 0%, the thermal conductivity was 1.3×10 -3 Ca1/cms°C. Note that this ceramic material differs in properties, thermal properties, etc. from the ceramic fiber molded article in this example. Incidentally, the water absorption rate (by immersion in water for 24 hours) of a product obtained by firing the same 200 mm square irregular tile 1 as in the present example under the same firing conditions using the firing tool 3 related to the conventional technology is 2.7%. Moreover, the number of times that the firing tool 3 could be used repeatedly was about 1 to 2 times.
これらの実験結果からも明らかな如く、本実施

成具１３の繰り返し使用回数も優れている。 As is clear from these experimental results, the firing tool 13 of this example has a lower thermal conductivity of 0.47×10 -3 Ca1/cms°C than the conventional firing tool 3, and has a lower water absorption rate of the fired product. The quality of the firing tool 13 is excellent, and the number of times the firing tool 13 can be used repeatedly is also excellent.

というとによるものである。従つて、焼成具１３

増減する等して開口率を変えればよい。 As described above, the reason why the firing tool 13 of this embodiment is superior in the number of times of repeated use of the firing tool itself and in the quality of the fired product is superior to the conventional firing tool 3. Depending on the selection of the material of the main body, the firing tool 13 can be made by drilling the through hole 14.
This is due to the effect of significantly reducing the mass (resulting in a significant decrease in heat capacity), that is, the amount of heat taken from the back surface 1b of the irregularly shaped tile during firing is extremely small. Therefore, the baking tool 13
If it is desired to change the heat capacity of the through hole 14, the aperture ratio may be changed by increasing or decreasing the number of through holes 14 or the like.

As explained above, in the case of the baking tool of the present invention, the through hole is formed in the baking tool body made of lightweight heat insulating material, so the heat capacity is very small, and the heat absorbed from the back side of the irregularly shaped tile during baking. Heat can be extremely reduced. Therefore, uneven firing such as loss of color development of the glaze of irregularly shaped tiles does not occur, and it is possible to fire quickly under the same firing conditions as flat tiles.
Furthermore, a coating layer of alumina or the like is formed on the entire surface of the firing tool, which improves its strength, so the firing tool will not fall apart during firing.
There is no warping, and no surface deformation such as warping is caused to irregularly shaped tiles during firing and softening. In other words, it is possible to fire irregularly shaped tiles that are excellent in terms of product.
