［産業上の利用分野］
本発明は、セラミックス成形材、特に押出成形により細
長く成形したセラミックス押出形材（以下セラミツゲス
長尺体という）の焼成方法と焼成装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method and apparatus for firing a ceramic molded material, particularly a ceramic extruded shape formed into a long and thin ceramic material by extrusion molding (hereinafter referred to as a ceramic elongated body).
［従来の技術］
セラミックス長尺体は、一般にセラミックス原料を押出
により長尺に成形し、これを乾燥後、炉に入れて焼成し
て作られるが、押出成形されたセラミックス長尺体は、
第１１図に示すように、×方向、Ｙ方向に変形しており
、真直ぐなものは皆無である。また、これを乾燥させた
ものは不均一な乾燥のために更に変形がカロゎる。[Prior Art] A long ceramic body is generally made by extruding a ceramic raw material into a long length, drying it, and then firing it in a furnace.
As shown in FIG. 11, they are deformed in the x direction and the y direction, and none of them are straight. Moreover, when this is dried, the deformation becomes even more severe due to uneven drying.
こうした長尺体を焼成すれば、焼成後の形状も変形した
ものにならざるを得ない。If such a long body is fired, the shape after firing will inevitably be deformed.
そこで押出成形などでつくったセラミックス長尺体をで
きるだけ真直ぐなものにする技術については、特公昭４

真直ぐな形状にしようとするものでる。Therefore, regarding the technology to make long ceramic bodies made by extrusion molding etc. as straight as possible,
No. 4-25703 is known. This is achieved by firing the long ceramic body in a suspended state.
There are things that try to make it into a straight shape.

用できるが、弧状や湾曲した形状のものを正確な形状に
焼成することはできなかった。[Problems to be Solved by the Invention] In the above-mentioned conventional technology, firing the elongated ceramic body in a suspended state has the effect of firing the long ceramic body into a straight body, but requires a vertically elongated firing furnace. Therefore, in order to equalize the heat distribution above and below the furnace,
Forced circulation of the heat medium is required, which requires energy. In addition, the long ceramic body shakes due to the circulation of the heat medium, and its hanging part may be damaged, so the shape of the long ceramic body is limited, and the work of suspending the long ceramic body from the top of the furnace is difficult. The problem is that it is difficult. Furthermore, although this method can be applied to straight shapes, it has not been possible to fire arcuate or curved shapes into accurate shapes.
そこで、本発明は、直線状、弧状、湾曲状など種々の形
状をしたセラミックス長尺体を精度よく、かつ、能率的
に作ることのできる焼成方法と焼成装置を提供せんとす
るものである。Therefore, the present invention aims to provide a firing method and a firing apparatus that can accurately and efficiently produce ceramic elongated bodies having various shapes such as linear, arcuate, and curved shapes.

形材の焼成装置である。[Means for Solving the Problems] The present invention involves extrusion molding a shape having a desired cross-sectional shape using a ceramic material, and extruding this molded body using a firing jig having at least two supporting surfaces facing in different directions. , a ceramic characterized in that the molded body is supported from below and heated to soften the molded body, the surface shape of the molded body is deformed along the support surface of the firing jig by its own weight, and then sintered. A method for firing an extruded material, and a firing jig having at least two supporting surfaces facing in different directions and capable of supporting an extruded ceramic material to be fired from below. This is a firing device for extruded ceramic shapes.
本発明において、セラミックス長尺体を焼成に先立って

直して焼成するのが良い。また、弧状、湾曲状のような
変形材の場合は、この乾燥の前に治具の支持面にほぼ沿
うように押えながら予め変形させる。In the present invention, if it is necessary to dry the elongated ceramic body prior to firing, the elongated ceramic body may be placed on the above-mentioned firing jig and dried. It is best to place the long ceramic body on a jig made of inexpensive materials with the same shape, dry it, and then place it back on the firing jig after drying and fire it, since no special properties are required. . Further, in the case of a deformable material having an arcuate or curved shape, the material is deformed in advance while being pressed so as to substantially follow the support surface of the jig before drying.
焼成用治具としては、加工性が良く耐熱性の材料である
Ａｌ２Ｏ：ｌが好適に用いられる。また、焼成用治具の
保持台としては耐熱性があってしかも強度の大きいＳｉ
Ｃが好適に用いられる。As the firing jig, Al2O:l, which is a material with good workability and heat resistance, is preferably used. In addition, as a holding base for the baking jig, we use Si, which has heat resistance and high strength.
C is preferably used.
焼成用治具はいくつかの小片に分離し、各小片の間隔は
セラミックス長尺体が軟化したときに垂れ下がらない程
度にあける。こうすることによって、小片間の間隔を通
して熱媒の循環が良くなりセラミックス長尺体を均一に
加熱することができる。The firing jig is divided into several pieces, and the intervals between the pieces are set to such an extent that the elongated ceramic body does not sag when it softens. By doing so, the circulation of the heating medium is improved through the intervals between the small pieces, and the elongated ceramic body can be heated uniformly.
また、焼成用治具の他の態様としては、セラミックス長
尺体と同程度の長さにして、全面に熱媒通過用の透孔を
多数設けたものでも良い。In addition, another embodiment of the firing jig may be one having a length comparable to that of the elongated ceramic body and having a large number of through holes for the passage of the heating medium over the entire surface.

にする。At least two supporting surfaces facing different directions in the firing jig typically have a V-shape when the outer surface of the elongated ceramic body is square. In addition, when the outer surface of the ceramic elongated body is circular, the central lower bottom part of the circular arc surface of the support surface is formed into an arc shape with a smaller curvature than the curvature of the circular cross section of the ceramic elongated body before firing. Thus, the elongated ceramic body is supported at two locations on both sides of the arcuate surface.

This arcuate surface is formed with a small curvature at the center. Therefore, when the elongated ceramic body 17 with a circular cross section before firing indicated by the dashed line is placed on the firing jig 16,
There will be a gap at the bottom. In other words, the elongated ceramic body 17 before firing is supported at two locations on the support surfaces 18 and 19. The fired elongated ceramic body 17' has a circular cross section as shown by the solid line, but in this case, the elongated ceramic body 17' has a curvature equal to that of the central portion of the arcuate surface and is supported by the central portion.
