Description

本発明は、焼成炉に関する。   The present invention relates to a firing furnace.

この種の焼成炉として、焼成領域を画成する炉体と、温度測定器とを備えるものが知られている（例えば、特許文献１及び２参照）。
特開平６−８８６８２号公報 特開２００４−１０１００８号公報 As this type of firing furnace, one having a furnace body defining a firing region and a temperature measuring device is known (see, for example, Patent Documents 1 and 2).
Japanese Patent Laid-Open No. 6-88682 JP 2004-101008 A

しかしながら、特許文献１及び２に記載された焼成炉には、次のような問題が生じる。   However, the firing furnace described in Patent Documents 1 and 2 has the following problems.

通常、温度測定器は、温度測定部（例えば、熱電対等）を収容する保護管を有している。特許文献１及び２に記載された焼成炉は、温度測定部が炉体の１箇所のみにおいて支持される構成であるため、上記保護管が熱により劣化して温度測定器全体が湾曲し、場合によっては破損する懼れがある。特に、焼成領域の中央部分の温度を測定するために、温度測定器を長くした場合、温度測定器（保護管）の湾曲が顕著となる。温度測定器の湾曲や破損は、温度測定が適切に行えない、温度測定器の交換が困難となるといった新たな問題を招来し、適正な焼成を行うことができなくなる。また、焼成炉が、被焼成物を搬送しながら焼成する連続炉である場合には、温度測定器の湾曲や破損は、搬送不良の要因ともなる。   Usually, the temperature measuring device has a protective tube that houses a temperature measuring unit (for example, a thermocouple). The firing furnaces described in Patent Documents 1 and 2 have a configuration in which the temperature measuring unit is supported only at one place of the furnace body, and thus the protective tube is deteriorated by heat and the entire temperature measuring device is curved. Some may be damaged. In particular, when the temperature measuring instrument is lengthened in order to measure the temperature of the central portion of the firing region, the curvature of the temperature measuring instrument (protective tube) becomes remarkable. The bending or breakage of the temperature measuring device causes new problems such that the temperature measurement cannot be performed properly and the replacement of the temperature measuring device becomes difficult, and proper baking cannot be performed. In addition, when the firing furnace is a continuous furnace that fires while conveying an object to be fired, the bending or breakage of the temperature measuring device also causes a conveyance failure.

本発明の目的は、温度測定器が湾曲あるいは破損した場合でも、適正な焼成を行うことが可能な焼成炉を提供することにある。   An object of the present invention is to provide a firing furnace capable of performing proper firing even when a temperature measuring device is bent or broken.

本発明に係る焼成炉は、焼成領域を画成する炉体と、温度測定器を収容する収容空間を画成すると共に、炉体の少なくとも所定の２箇所において端部が支持される保護部材と、を備え、収容空間は、温度測定器を炉体の外側から収容空間へ導入可能となるように炉体の外側空間と繋がっていることを特徴とする。   A firing furnace according to the present invention includes a furnace body that defines a firing region, a housing space that houses a temperature measuring device, and a protection member whose ends are supported at at least two predetermined locations of the furnace body. The housing space is connected to the outer space of the furnace body so that the temperature measuring device can be introduced into the housing space from the outside of the furnace body.

本発明に係る焼成炉では、温度測定器を収容する収容空間を画成する保護部材は、当該保護部材の端部が炉体の少なくとも所定の２箇所において支持されることにより、炉体に配置されることとなる。このように、保護部材の端部が炉体の少なくとも所定の２箇所において支持されるので、保護部材の湾曲が抑制され、その破損を防ぐことができる。温度測定器は保護部材の収容空間に配されるため、温度測定器が熱により湾曲する場合でも、湾曲の度合いが保護部材により抑制され、破損する可能性は極めて低い。また、保護部材の収容空間は温度測定器を炉体の外側から収容空間へ導入可能となるように炉体の外側空間と繋がっているので、温度測定器を容易に配することができ、交換等も容易となる。これらの結果、焼成炉での焼成に悪影響を及ぼすようなことはない。   In the firing furnace according to the present invention, the protective member that defines the storage space for storing the temperature measuring device is arranged in the furnace body by supporting the end portions of the protective member at at least two predetermined locations of the furnace body. Will be. Thus, since the edge part of a protection member is supported in at least two predetermined places of a furnace body, the curve of a protection member is suppressed and the breakage can be prevented. Since the temperature measuring device is disposed in the housing space of the protective member, even when the temperature measuring device is bent by heat, the degree of bending is suppressed by the protective member and the possibility of breakage is extremely low. In addition, the storage space of the protection member is connected to the outer space of the furnace body so that the temperature measurement device can be introduced into the storage space from the outside of the furnace body, so that the temperature measurement device can be easily arranged and replaced. Etc. are also easy. As a result, there is no adverse effect on firing in the firing furnace.

また、収容空間は、複数の温度測定器を収容する複数の領域を含んでいることが好ましい。この場合、焼成領域の温度を測定するための温度測定器と、当該温度測定器の温度校正を行うための温度測定器とを収容空間に配することができる。   Moreover, it is preferable that the accommodation space includes a plurality of regions for accommodating a plurality of temperature measuring devices. In this case, a temperature measuring device for measuring the temperature of the firing region and a temperature measuring device for performing temperature calibration of the temperature measuring device can be arranged in the accommodation space.

また、保護部材と炉体との間には、シール部材が配設されていることが好ましい。この場合は、炉体内の雰囲気空気が炉体外に逃げるのと、焼成領域の温度が低下するのとを防ぐことができる。   Moreover, it is preferable that a seal member is disposed between the protective member and the furnace body. In this case, it is possible to prevent the atmospheric air in the furnace body from escaping to the outside of the furnace body and the temperature of the firing region from being lowered.

また、保護部材は、管形状を呈していることが好ましい。   The protective member preferably has a tubular shape.

また、保護部材の開口端には、着脱自在なシール部材が配設されていることが好ましい。この場合、収容空間が外側空間から遮断されることとなり、外側空間の影響を受けることなく適切な温度測定を行い得る空間を形成できる。   Moreover, it is preferable that a detachable seal member is disposed at the opening end of the protection member. In this case, the accommodation space is blocked from the outer space, and a space in which appropriate temperature measurement can be performed without being affected by the outer space can be formed.

また、炉体は、対向する一対の炉壁を有し、保護部材は、管形状を呈しており、一対の炉壁を貫通した状態で当該炉壁に支持されていることが好ましい。この場合、保護部材の支持を確実に行うことができると共に、収容空間が外側空間と繋がり得る構成の保護部材を極めて容易に実現することができる。   Moreover, it is preferable that a furnace body has a pair of furnace wall which opposes, the protection member is exhibiting the pipe shape, and is supported by the said furnace wall in the state which penetrated a pair of furnace wall. In this case, the protection member can be reliably supported, and a protection member having a configuration in which the accommodation space can be connected to the outer space can be realized very easily.

また、収容空間は、複数の温度測定器を収容する複数の領域を含んでおり、複数の領域は、保護部材の長手方向に並ぶように位置していることが好ましい。この場合、焼成領域の温度を測定するための温度測定器と、当該温度測定器の温度校正を行うための温度測定器とを収容空間に配することができる。特に、一方の開口端から焼成領域の温度を測定するための温度測定器を挿入した状態でも、他方の開口端から温度校正を行うための温度測定器を容易に挿入することができる。   The housing space includes a plurality of regions for housing a plurality of temperature measuring devices, and the plurality of regions are preferably positioned so as to be aligned in the longitudinal direction of the protective member. In this case, a temperature measuring device for measuring the temperature of the firing region and a temperature measuring device for performing temperature calibration of the temperature measuring device can be arranged in the accommodation space. In particular, even when a temperature measuring device for measuring the temperature of the firing region is inserted from one opening end, a temperature measuring device for temperature calibration can be easily inserted from the other opening end.

本発明によれば、温度測定器が湾曲あるいは破損した場合でも、適正な焼成を行うことが可能な焼成炉を提供することができる。   According to the present invention, it is possible to provide a firing furnace capable of performing proper firing even when the temperature measuring device is bent or broken.

以下、添付図面を参照して、本発明の好適な実施形態について詳細に説明する。なお、説明において、同一要素又は同一機能を有する要素には、同一符号を用いることとし、重複する説明は省略する。本実施形態は、本発明を連続炉（詳細には、ローラハース炉）に適用した例である。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

保護部材４０は、ヒータ３０の近傍に位置している。保護部材４０は、左右の炉壁１１，１２を貫通しており、その端部が当該各炉壁１１，１２に支持されることにより炉体１０に設けられている。炉壁１１，１２における保護部材４０を貫通させる貫通孔を形成する部分には、メガネ煉瓦が使用されている。保護部材４０と各炉壁１１，１２との間には、シール部材４１が配設されている。保護部材４０の材料としては、耐熱性を有するセラミック材料、例えば、アルミナ、ニュームライト、又はＳｉＣ等が用いられる。シール部材４１の材料としては、煉瓦、セラミックファイバー、アルミナ等が用いられる。   The protection member 40 is located in the vicinity of the heater 30. The protection member 40 passes through the left and right furnace walls 11 and 12, and the end portions thereof are provided on the furnace body 10 by being supported by the furnace walls 11 and 12.

保護部材４０は、直線状に伸びた管形状を呈しており、両端が開口している。保護部材４０は、温度測定器Ｔ１を収容する収容空間Ｓを画成する。収容空間Ｓは、温度測定器Ｔ１を炉体１０の外側から収容空間Ｓへ導入可能となるように炉体１０の外側空間と繋がっている。収容空間Ｓは、複数の温度測定器を収容する複数の領域を含んでいる。複数の領域は、保護部材４０の長手方向に並ぶように位置している。   The protection member 40 has a tubular shape extending in a straight line, and both ends are open. The protection member 40 defines a housing space S that houses the temperature measuring device T1. The accommodation space S is connected to the outer space of the furnace body 10 so that the temperature measuring device T1 can be introduced from the outside of the furnace body 10 into the accommodation space S. The accommodation space S includes a plurality of regions that accommodate a plurality of temperature measuring devices. The plurality of regions are positioned so as to be aligned in the longitudinal direction of the protection member 40.

保護部材４０には、一方の開口端から温度測定器Ｔ１が挿入されて、配置されている。温度測定器Ｔ１は、焼成領域の温度を測定するための温度測定器である。ヒータ３０は、温度測定器Ｔ１にて検知された温度に基づいて、図示しない制御回路によりフィードバック制御される。温度測定器Ｔ１は、シール部材４２を介して保護部材４０に支持される。シール部材４２の材料としては、煉瓦、セラミックファイバー、アルミナ、シリコン等が用いられる。   A temperature measuring device T1 is inserted into the protective member 40 from one opening end. The temperature measuring device T1 is a temperature measuring device for measuring the temperature of the firing region. The heater 30 is feedback-controlled by a control circuit (not shown) based on the temperature detected by the temperature measuring device T1. The temperature measuring device T1 is supported by the protective member 40 via the seal member 42. As a material for the seal member 42, brick, ceramic fiber, alumina, silicon, or the like is used.

温度測定器Ｔ１は、図４に示されるように、熱電対素線Ｔ１１と、絶縁管Ｔ１２と、保護管Ｔ１３とを有している。図４は、温度測定器の構成を示す概略図であり、特に先端部分を示す。熱電対素線Ｔ１１は、絶縁管Ｔ１２内に位置している。熱電対素線Ｔ１１の測温接点Ｔ１４は、絶縁管Ｔ１２から露出している。熱電対素線Ｔ１１及び絶縁管Ｔ１２は、保護管Ｔ１３内に位置している。なお、保護管Ｔ１３は、必ずしも必要ではない。   As shown in FIG. 4, the temperature measuring device T1 includes a thermocouple element T11, an insulating tube T12, and a protective tube T13. FIG. 4 is a schematic diagram showing the configuration of the temperature measuring device, and particularly shows the tip portion. The thermocouple strand T11 is located in the insulating tube T12. A temperature measuring contact T14 of the thermocouple wire T11 is exposed from the insulating tube T12. The thermocouple strand T11 and the insulating tube T12 are located in the protective tube T13. The protective tube T13 is not always necessary.

保護部材４０の他方の開口端には、着脱自在なシール部材４３が配設されている。シール部材４３の材料としては、煉瓦、セラミックファイバー、アルミナ、シリコン、金属（例えば、ステンレス鋼）等が用いられる。   A removable seal member 43 is disposed at the other opening end of the protection member 40. As a material of the seal member 43, brick, ceramic fiber, alumina, silicon, metal (for example, stainless steel) or the like is used.

ここで、図５を参照して、温度測定器Ｔ１の温度校正について説明する。   Here, temperature calibration of the temperature measuring device T1 will be described with reference to FIG.

保護部材４０の他方の開口端からシール部材４３を外し、他方の開口端から温度測定器Ｔ２を挿入する。温度測定器Ｔ２は、温度測定器Ｔ１の温度校正を行うための温度測定器温度であって、温度測定器Ｔ１と同様に構成を備えている。温度測定器Ｔ２は、当該温度測定器Ｔ２の測温接点が温度測定器Ｔ１の測温接点Ｔ１４と近接する位置まで挿入される。これにより、２つの温度測定器Ｔ１，Ｔ２が収容空間Ｓに配されることとなる。そして、温度測定器Ｔ２からの出力と温度測定器Ｔ１からの出力とに基づいて、温度測定器Ｔ１の校正値を求める。   The seal member 43 is removed from the other opening end of the protection member 40, and the temperature measuring device T2 is inserted from the other opening end. The temperature measuring device T2 is a temperature measuring device temperature for temperature calibration of the temperature measuring device T1, and has the same configuration as the temperature measuring device T1. The temperature measuring device T2 is inserted to a position where the temperature measuring contact of the temperature measuring device T2 is close to the temperature measuring contact T14 of the temperature measuring device T1. Thereby, the two temperature measuring devices T1 and T2 are arranged in the accommodation space S. Then, based on the output from the temperature measuring device T2 and the output from the temperature measuring device T1, a calibration value of the temperature measuring device T1 is obtained.

以上のように、本実施形態によれば、温度測定器Ｔ１を収容する収容空間Ｓを画成する保護部材４０は、当該保護部材４０の端部が炉体１０の２箇所において支持されることにより、炉体１０に配置されることとなる。このように、保護部材４０の端部が炉体１０の２箇所において支持されるので、保護部材４０の湾曲が抑制され、その破損を防ぐことができる。温度測定器Ｔ１は保護部材４０の収容空間Ｓに配されるため、温度測定器Ｔ１が熱により湾曲する場合でも、湾曲の度合いが保護部材４０により抑制され、破損する可能性は極めて低い。また、保護部材４０の収容空間Ｓは温度測定器Ｔ１を炉体１０の外側から収容空間Ｓへ導入可能となるように炉体１０の外側空間と繋がっているので、温度測定器Ｔ１を容易に配することができ、交換等も容易となる。これらの結果、温度測定器Ｔ１が湾曲あるいは破損した場合でも、焼成炉１での焼成に悪影響を及ぼすようなことはなく、適正な焼成を行うことができる。   As described above, according to the present embodiment, the protective member 40 that defines the accommodation space S that accommodates the temperature measuring device T1 is supported at two ends of the furnace body 10 at the ends of the protective member 40. Therefore, it will be arranged in the furnace body 10. Thus, since the edge part of the protection member 40 is supported in two places of the furnace body 10, the curve of the protection member 40 is suppressed and the damage can be prevented. Since the temperature measuring device T1 is arranged in the accommodation space S of the protective member 40, even when the temperature measuring device T1 is bent by heat, the degree of bending is suppressed by the protective member 40 and the possibility of breakage is extremely low. In addition, since the storage space S of the protection member 40 is connected to the outer space of the furnace body 10 so that the temperature measuring device T1 can be introduced into the storage space S from the outside of the furnace body 10, the temperature measurement device T1 can be easily provided. It can be arranged and exchange etc. are also easy. As a result, even when the temperature measuring device T1 is bent or broken, the firing in the firing furnace 1 is not adversely affected and proper firing can be performed.

本実施形態において、収容空間Ｓは、２つの温度測定器Ｔ１，Ｔ２を収容する複数の領域を含んでいる。これにより、焼成領域の温度を測定するための温度測定器Ｔ１と、当該温度測定器Ｔ１の温度校正を行うための温度測定器Ｔ２とを収容空間Ｓに配することができる。   In the present embodiment, the accommodation space S includes a plurality of regions that accommodate the two temperature measuring devices T1 and T2. Thereby, the temperature measuring device T1 for measuring the temperature of the firing region and the temperature measuring device T2 for performing temperature calibration of the temperature measuring device T1 can be arranged in the accommodation space S.

また、本実施形態において、保護部材４０と炉体１０との間には、シール部材４１が配設されている。これにより、炉体１０内の雰囲気空気が炉体１０の外に逃げるのと、焼成領域の温度が低下するのとを防ぐことができる。   In the present embodiment, a seal member 41 is disposed between the protection member 40 and the furnace body 10. Thereby, it can prevent that the atmospheric air in the furnace body 10 escapes out of the furnace body 10, and the temperature of a baking area | region falls.

また、本実施形態において、保護部材４０の他方の開口端には、シール部材４３が配設されている。この場合、一方の開口端から温度測定器Ｔ１が挿入された状態で収容空間Ｓが外側空間から遮断されることとなり、外側空間の影響を受けることなく適切な温度測定を行い得る空間を形成できる。   In the present embodiment, a seal member 43 is disposed at the other opening end of the protection member 40. In this case, the accommodation space S is blocked from the outer space with the temperature measuring device T1 inserted from one opening end, and a space capable of performing appropriate temperature measurement without being affected by the outer space can be formed. .

また、本実施形態において、炉体１０は、対向する一対の炉壁１１，１２を有し、保護部材４０は、一対の炉壁１１，１２を貫通した状態で当該炉壁１１，１２に支持されている。これにより、保護部材４０の支持を確実に行うことができると共に、収容空間Ｓが外側空間と繋がり得る構成の保護部材を極めて容易に実現することができる。   In this embodiment, the furnace body 10 has a pair of opposed furnace walls 11 and 12, and the protection member 40 is supported by the furnace walls 11 and 12 in a state of passing through the pair of furnace walls 11 and 12. Has been. Thereby, while being able to support the protection member 40 reliably, the protection member of the structure which the accommodation space S can connect with outer side space can be implement | achieved very easily.

また、上記複数の領域は、保護部材４０の長手方向に並ぶように位置している。これにより、一方の開口端から温度測定器Ｔ１を挿入した状態でも、他方の開口端から温度測定器Ｔ２を容易に挿入することができる。この結果、各温度測定器Ｔ１，Ｔ２の測温接点を近接させることができ、温度測定器Ｔ１の温度校正を効果的に行うことができる。   The plurality of regions are positioned so as to be aligned in the longitudinal direction of the protection member 40. Thereby, even if the temperature measuring device T1 is inserted from one opening end, the temperature measuring device T2 can be easily inserted from the other opening end. As a result, the temperature measuring contacts of the temperature measuring devices T1 and T2 can be brought close to each other, and the temperature calibration of the temperature measuring device T1 can be effectively performed.

保護部材５０は、上述した保護部材４０と同様に、ヒータ３０の近傍に位置している。保護部材５０は、炉壁１３を貫通しており、その端部が炉壁１３に支持されることにより炉体１０に設けられている。保護部材５０は、略Ｌ字状の管形状を呈しており、両端が開口している。保護部材５０は、温度測定器Ｔ１を収容する収容空間Ｓを画成する。収容空間Ｓは、複数の温度測定器を収容する複数の領域を含んでいる。   The protection member 50 is located in the vicinity of the heater 30 in the same manner as the protection member 40 described above. The protection member 50 penetrates the furnace wall 13 and is provided in the furnace body 10 by supporting an end portion of the protection member 50 on the furnace wall 13. The protection member 50 has a substantially L-shaped tube shape, and both ends are open.

焼成炉１は、炉体１０と、ローラ２０と、ヒータ３０と、保護部材４０，５０とを備えている。保護部材５０は、互いに隣り合う炉壁１１，１３を貫通しており、その端部が各炉壁１１，１３に支持されることにより炉体１０に設けられている。   The firing furnace 1 includes a furnace body 10, a roller 20, a heater 30, and protective members 40 and 50. The protection member 50 passes through the furnace walls 11 and 13 adjacent to each other, and the end portions thereof are provided on the furnace body 10 by being supported by the furnace walls 11 and 13.

次に、図１０及び図１１に基づいて、本実施形態に係る焼成炉の一変形例について説明する。図１０及び図１１は、本実施形態に係る焼成炉の一変形例を示す概略断面図である。図１０は、搬送方向に平行な断面での構成を示す。図１１は、搬送方向に直交する断面での構成を示す。   Next, based on FIG.10 and FIG.11, the modification of the baking furnace which concerns on this embodiment is demonstrated. FIG.10 and FIG.11 is a schematic sectional drawing which shows the modification of the baking furnace which concerns on this embodiment. FIG. 10 shows a configuration in a cross section parallel to the transport direction. FIG. 11 shows a configuration in a cross section orthogonal to the transport direction.

焼成炉１は、炉体１０と、ローラ２０と、ヒータ３０と、保護部材４０，６０とを備えている。   The firing furnace 1 includes a furnace body 10, a roller 20, a heater 30, and protective members 40 and 60.

保護部材６０は、上述した保護部材４０，５０と同様に、ヒータ３０の近傍に位置している。保護部材６０は、一対の炉壁１１，１２及び当該各炉壁１１，１２に隣り合う炉壁１３を貫通しており、その端部が各炉壁１１，１２，１３に支持されることにより炉体１０に設けられている。   The protection member 60 is located in the vicinity of the heater 30 in the same manner as the protection members 40 and 50 described above. The protective member 60 passes through the pair of furnace walls 11, 12 and the furnace wall 13 adjacent to the furnace walls 11, 12, and ends thereof are supported by the furnace walls 11, 12, 13. It is provided in the furnace body 10.

保護部材６０は、管形状を呈しており、直線状に伸びる第１の部分６１と当該第１の部分６１から分岐する第２の部分６２とを有している。保護部材６０の第１及び第２の部分６１，６２の各端が、開口している。保護部材６０は、温度測定器Ｔ１を収容する収容空間Ｓを画成する。収容空間Ｓは、複数の温度測定器を収容する複数の領域を含んでいる。保護部材６０は、３つの温度測定器を収容することができる。   The protection member 60 has a tubular shape, and includes a first portion 61 that extends linearly and a second portion 62 that branches from the first portion 61. Each end of the first and second portions 61 and 62 of the protection member 60 is open. The protection member 60 defines an accommodation space S in which the temperature measuring device T1 is accommodated. The accommodation space S includes a plurality of regions that accommodate a plurality of temperature measuring devices. The protection member 60 can accommodate three temperature measuring devices.

保護部材６０には、一つの開口端（第１の部分６１の一方の開口端）から温度測定器Ｔ１が挿入されて、配置されている。保護部材６０の残りの開口端には、着脱自在なシール部材４３が配設されている。保護部材６０の残りの開口端のいずれか一つの開口端（第１の部分６１の他方の開口端、あるいは、第２の部分６２の開口端）からは、シール部材４３を外すことにより、温度測定器Ｔ２を挿入することが可能となる。   A temperature measuring device T1 is inserted into the protective member 60 from one opening end (one opening end of the first portion 61) and disposed. A detachable seal member 43 is disposed at the remaining opening end of the protection member 60. By removing the seal member 43 from any one of the remaining open ends of the protective member 60 (the other open end of the first portion 61 or the open end of the second portion 62), the temperature is increased. It becomes possible to insert the measuring device T2.

以上のように、いずれの変形例においても、上述した本実施形態と同様に、温度測定器Ｔ１を収容する収容空間Ｓを画成する保護部材４０，５０，６０は、当該保護部材４０，５０，６０の端部が炉体１０の２箇所以上において支持されることにより、炉体１０に配置されることとなる。このように、保護部材４０，５０，６０の端部が炉体１０の２箇所以上において支持されるので、保護部材４０，５０，６０の湾曲が抑制され、その破損を防ぐことができる。したがって、温度測定器Ｔ１が湾曲あるいは破損した場合でも、焼成炉１での焼成に悪影響を及ぼすようなことはなく、適正な焼成を行うことができる。   As described above, in any of the modifications, the protection members 40, 50, 60 that define the accommodation space S that accommodates the temperature measuring device T1 are the protection members 40, 50 as in the above-described embodiment. , 60 are supported at two or more places in the furnace body 10, so that they are arranged in the furnace body 10. Thus, since the edge part of the protection members 40, 50, and 60 is supported in two or more places of the furnace body 10, the curve of the protection members 40, 50, and 60 is suppressed, and the damage can be prevented. Therefore, even when the temperature measuring device T1 is bent or damaged, the firing in the firing furnace 1 is not adversely affected and proper firing can be performed.

以上、本発明の好適な実施形態について説明してきたが、本発明は必ずしもこれらの実施形態に限定されるものではない。例えば、保護部材４０は、図１２に示されるように、炉体１０を貫通していなくてもよい。なお、保護部材４０は、一方の端部が炉体１０に支持されるのであれば、他方の端部は炉体１０に接触していなくてもよい。保護部材４０が所定量だけ湾曲した際に、炉体１０に接触して支持さればよい。この所定量は、特に、被焼成物の搬送に悪影響を与えない範囲で設定することができる。   The preferred embodiments of the present invention have been described above, but the present invention is not necessarily limited to these embodiments. For example, the protection member 40 does not have to penetrate the furnace body 10 as shown in FIG. As long as one end of the protection member 40 is supported by the furnace body 10, the other end may not be in contact with the furnace body 10. What is necessary is just to contact and support the furnace body 10 when the protection member 40 curves by a predetermined amount. This predetermined amount can be set within a range that does not adversely affect the conveyance of the object to be fired.

また、本実施形態においては、保護部材４０，５０，６０をヒータ３０の近傍に位置させているが、これに限られることなく、ヒータ３０から離して、搬送される被焼成物の近傍に位置させてもよい。   Further, in the present embodiment, the protective members 40, 50, 60 are positioned in the vicinity of the heater 30, but the present invention is not limited to this, and the protective members 40, 50, 60 are positioned in the vicinity of the object to be fired away from the heater 30.
