Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a firing jig for a plate-shaped object to be fired, such as a concrete panel.

[Background Art] Conventionally, an object to be fired 1 such as a concrete panel has been fired by placing it horizontally on a firing jig A' formed by stacking firebricks 9 as shown in FIG. Particularly when a glaze is applied to the object 1 to be fired, there is a problem in that dust and the like adhere to the glazed surface, making it impossible to obtain a good glaze. For this reason, as shown in FIG. 4, the object to be fired 1 is held vertically on a cart 8 for firing, but in this case, as shown in FIG. As a result, the object to be fired 1 was warped. For this reason, the present inventor has already erected a vertical member 5 on a mounting table 5 made of refractory material, as shown in Fig. 6, and attached a support plate 3' to the vertical member 5 at a predetermined angle. A firing jig A'' is devised, and the object to be fired 1 is placed vertically at an angle, the inclined side surface 2 of the object to be fired 1 is supported by the support plate 3', and the lower end is held on the pedestal 10. By firing, the warpage of the object 1 to be fired was small, and even when the glaze was applied to the object 1 to be fired, no dust adhered to the glazed surface, and a good glaze could be obtained. However, the thermal expansion of the support plate 3 and the mounting table 5 could not be completely alleviated, and the object 1 to be fired was softened and deformed during the firing process.

[Purpose of the invention] The present invention was made in view of the above circumstances, and its purpose is to provide a firing jig for vertically placing objects to be fired at an angle, and to apply glaze to the objects to be fired. It is an object of the present invention to provide a firing jig which not only does not allow dust to adhere to the glazed surface even after application, but also can reliably prevent deformation of the object to be fired.

[Disclosure of the invention] The firing jig of the present invention is a firing jig for vertically placing a plate-shaped object 1 to be fired at an angle.
A roller 6 made of a heat-resistant material is installed on at least one of a support plate 3 that supports the inclined side surface 2 of the object 1 and a mounting table 5 that supports the lower end surface 4 of the object to be fired. was achieved. That is, since the object to be fired 1 is placed vertically at an angle, even if the glaze is applied to the object to be fired, no dust will adhere to the glaze-treated surface, and the support plate 3 and/or Since the roller 6 is installed on the mounting table 5, the stress caused by thermal expansion of the support plate 3 and/or the mounting table 5 can be alleviated by the roller 6, and deformation of the object to be fired 1 during the firing process can be reliably prevented. It is.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. A vertical member 7, which is a metal frame, is erected approximately in the center along the longitudinal direction of the mounting table 5, which is formed by paving refractory bricks and covering them with stainless steel plates. Support plates 3 made of aluminum are tilted and fixed to a vertical member 7 so as to face each other. The inclination angle θ of the support plate 3 is preferably 87° or less. If the inclination angle is larger than this, there is a risk that the object to be fired 1 will be deformed due to its own weight. In this embodiment, a plurality of alumina rollers 6 are rotatably installed on the side surface of the support plate 3 and on the upper surface of both sides of the mounting table 5 at predetermined intervals in the longitudinal direction.

The object to be fired 1 is placed in this firing jig A, for example, 1m×
A 3 m large ceramic concrete panel is arranged with its inclined side surface 2 in contact with the roller 6 of the support plate 3 and its lower end surface 4 placed on the roller 6 of the mounting table 5. As shown in FIG. 2, the plurality of firing jigs A to which the objects 1 to be fired are attached are placed on a trolley 8 and carried into the firing furnace, and the objects 1 to be fired are heated at, for example, 900°C, 12 It is baked over time.

[Effects of the invention] The present invention is a baking jig for tilting and vertically placing a plate-shaped object to be baked, and includes a support plate that supports the inclined side surface of the object to be baked, and a lower end surface of the object to be baked. Since a roller made of heat-resistant material is installed on at least one side of the mounting table that supports the The support plate and/or the rollers installed on the plate and/or the mounting table.
Stress caused by thermal expansion of the mounting table can be alleviated, and deformation of the object to be fired during the firing process can be reliably prevented.
