Description

本発明は、各種の金属製品を熱処理等するために、これら金属製品を搭載して加熱炉や熱処理炉に侵入し搬送する金属製品加熱用台車に関するものである。   TECHNICAL FIELD The present invention relates to a metal product heating carriage that mounts these metal products and enters and conveys them into a heating furnace or a heat treatment furnace in order to heat-treat various metal products.

各種の金属製品Ｍに熱処理等を施すために、それら金属製品Ｍを搭載して加熱炉や熱処理炉といった炉に侵入して炉内を搬送する金属製品加熱用台車２０は、通常、図３，図４に示すように、鋼鉄製台車フレーム２を囲む外周端部を除く部分に煉瓦３を上載し、前記外周端部に、煉瓦受金物７を溶接で固定し、さらに、煉瓦受金物７の露出面を、シリカやアルミナを含む耐火性のキャスタブル８を打設して覆うことによって構成されている。   In order to perform heat treatment or the like on various metal products M, a metal product heating carriage 20 that carries these metal products M, enters a furnace such as a heating furnace or a heat treatment furnace, and transports the inside of the furnace is usually shown in FIG. As shown in FIG. 4, a brick 3 is placed on a portion excluding the outer peripheral end portion surrounding the steel cart frame 2, and a brick receiver 7 is fixed to the outer peripheral end by welding. The exposed surface is formed by placing and covering a fire-resistant castable 8 containing silica or alumina.

こうした構成の金属製品加熱用台車２０は、煉瓦３、煉瓦受金物７およびキャスタブル８で構成されているので、耐火性に優れるといった特長を備える。また、キャスタブル８の膨張によって、加熱炉や熱処理炉などの炉体１１に接触することがないように、キャスタプル８と炉体１１の間には間隙Ｇが確保され、間隙Ｇの下端はシール材１０ｂで塞がれている。   Since the metal product heating cart 20 having such a configuration is composed of the brick 3, the brick receiver 7, and the castable 8, it has a feature of excellent fire resistance. Further, a gap G is secured between the caster pull 8 and the furnace body 11 so that the castable 8 does not come into contact with the furnace body 11 such as a heating furnace or a heat treatment furnace due to the expansion of the castable 8, and the lower end of the gap G is a sealing material. It is closed at 10b.

なお、金属製品に熱処理を施す装置は、例えば、特許文献１に記載されている。
特開２００１−２７１１１８号公報 An apparatus for performing a heat treatment on a metal product is described in Patent Document 1, for example.
JP 2001-271118 A

しかしながら、上記した従来の金属製品加熱用台車２０は、例えば、煉瓦受金物７が傾いたり、キャスタブル８が熱によって膨張することに起因して、煉瓦受金物７が破損したり、あるいはキャスタブル８が欠損する場合がある。このように、煉瓦受金物７やキャスタプル８あるいはそれらに相当する部材に障害がある際の補修が極めて面倒であるといった問題がある。   However, in the conventional metal product heating cart 20 described above, the brick receiver 7 is damaged or the castable 8 is damaged due to, for example, the brick receiver 7 being inclined or the castable 8 is expanded by heat. It may be missing. As described above, there is a problem that the repair when the brick receiving object 7, the castable 8 or the members corresponding thereto are faulty is extremely troublesome.

すなわち、この金属製品加熱用台車２０は、台車フレーム２の外周端部に煉瓦受金物７を溶接によって固定し、その露出面にキャスタブル８を打設しているので、例えば、煉瓦受金物７に問題が発生した場合には、まず、キャスタブル８を解体した後、煉瓦受金物７を補修または交換し、再び、キャスタブル８を打設するといった工程を必要とする。
従って、作業が極めて面倒であり、多大な時間と費用を要する。また、補修に多大な時間を要するので加熱炉等を一旦停止させる必要が生じ、これにより、生産性が低下するといった問題もある。 That is, in this metal product heating cart 20, the brick receiver 7 is fixed to the outer peripheral end of the cart frame 2 by welding, and the castable 8 is placed on the exposed surface thereof. When a problem occurs, first, after disassembling the castable 8, the brick receiving material 7 is repaired or replaced, and the castable 8 is placed again.
Therefore, the work is extremely troublesome and requires a lot of time and cost. In addition, since a great deal of time is required for repair, it is necessary to temporarily stop the heating furnace and the like, thereby causing a problem that productivity is lowered.

なお、特許文献１には、金属製品加熱用台車に関する記載はない。   Note that Patent Document 1 does not describe a metal product heating cart.

なお、カッコ内の記号は、図面および後述する発明を実施するための最良の形態に記載された対応要素または対応事項を示す。   Symbols in parentheses indicate corresponding elements or corresponding matters described in the drawings and the best mode for carrying out the invention described later.

本発明の請求項１に記載の金属製品加熱用台車によれば、台車フレームの外周端面にボルトなどの締結部材によって着脱自在に取付けられる取付部の上面に、主耐火物の外周端面に隣接する副耐火物を固定した交換部材を備えるので、副耐火物の補修を容易かつ短時間で行うことができる。   According to the cart for heating a metal product according to the first aspect of the present invention, the outer surface of the main refractory is adjacent to the outer peripheral end surface of the mounting portion that is detachably attached to the outer peripheral end surface of the cart frame by a fastening member such as a bolt. Since the replacement member to which the auxiliary refractory is fixed is provided, the auxiliary refractory can be repaired easily and in a short time.

すなわち、副耐火物が欠損した場合、交換部材だけを、ボルトを外して台車フレームから取り外した後、それに代わる新たな交換部材を台車フレームにボルトで取付けることができる。
従って、副耐火物の補修を、極めて容易かつ短時間に終えることができ、これにより、補修に要する費用を削減し、また、加熱炉等を停止させる必要もないので、生産性を低下させることもない。 That is, when the auxiliary refractory is lost, only the replacement member can be removed from the carriage frame by removing the bolt, and then a new replacement member can be attached to the carriage frame with the bolt.
Therefore, the repair of the secondary refractory can be completed very easily and in a short time, thereby reducing the cost required for the repair and reducing the productivity because it is not necessary to stop the heating furnace or the like. Nor.

また、請求項２に記載の金属製品加熱用台車によれば、請求項１に記載の発明の作用効果に加えて、主耐火物と副耐火物を、同一の耐火材で構成したので、例えば、ストックする耐火材の種類を少なくすることができ、経済性を高めることができる。   Moreover, according to the cart for metal product heating according to claim 2, in addition to the function and effect of the invention according to claim 1, the main refractory and the auxiliary refractory are made of the same refractory material. The kind of refractory material to stock can be reduced, and the economy can be improved.

また、請求項３に記載の金属製品加熱用台車によれば、請求項１および２に記載の発明の作用効果に加えて、前記主耐火物を、煉瓦で構成したので、煉瓦の持つ優れた耐火性により、耐久性を高めることができる。   In addition, according to the cart for heating a metal product according to claim 3, in addition to the function and effect of the invention according to claims 1 and 2, the main refractory is made of brick, so that the excellent brick has Durability can be enhanced by fire resistance.

また、請求項４に記載の金属製品加熱用台車によれば、請求項１乃至３に記載の発明の作用効果に加えて、副耐火物の全体を同一の耐火材で構成したので、製造が容易で経済的である。   Further, according to the cart for heating a metal product according to claim 4, in addition to the function and effect of the invention according to claims 1 to 3, the sub-refractory is entirely made of the same refractory material. Easy and economical.

さらに、請求項５に記載の金属製品加熱用台車によれば、請求項１乃至４に記載の発明の作用効果に加えて、副耐火物を、取付部の上面に固定した受金物と、受金物の少なくとも露出面を覆う、シリカおよびアルミナを含むキャスタブル、あるいはシリカとアルミナのうちいずれか一つを含むキャスタブルとで構成したので、副耐火物の性能を高めることができる。   Furthermore, according to the metal product heating cart described in claim 5, in addition to the operation and effect of the invention described in claims 1 to 4, the sub-refractory is fixed to the upper surface of the mounting portion, Since the castable containing silica and alumina covering at least the exposed surface of the metal or the castable containing any one of silica and alumina is used, the performance of the auxiliary refractory can be improved.

すなわち、受金物の金属が持つ高い剛性によって主耐火物が台車フレームから横滑りするのを防止し、また、受金物の露出面を覆うキャスタブルによって受金物が高熱によって変形等するのを防止する。この両者の働きによって、副耐火物としての優れた性能を発揮することができる。   That is, the main refractory is prevented from slipping from the carriage frame due to the high rigidity of the metal of the received material, and the received material is prevented from being deformed by high heat by the castable covering the exposed surface of the received material.

図１乃至図３を参照して、本発明の実施形態に係る金属製品加熱用台車１について説明する。図１は、金属製品加熱用台車１を示すもので、図３のＡ−Ａ線拡大断面図である。また、図２は、交換部材４を台車フレーム２から外した状態を示す断面図である。なお、従来例で示したものと同一部分には同一符号を付した。   A metal product heating cart 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. 1 shows a cart 1 for heating a metal product, and is an enlarged sectional view taken along line AA in FIG. FIG. 2 is a cross-sectional view showing a state in which the replacement member 4 is removed from the carriage frame 2. In addition, the same code | symbol was attached | subjected to the same part as what was shown in the prior art example.

本実施形態に係る金属製品加熱用台車１は、金属製品Ｍに熱処理を施すために、その金属製品Ｍを上面に搭載して熱処理炉に侵入するとともに炉内を搬送する台車であり、主に台車フレーム２，主耐火物３，および交換部材３０を備え、交換部材３０を容易に分離可能にしている。   A cart 1 for heating a metal product according to the present embodiment is a cart that mounts the metal product M on the upper surface and enters the heat treatment furnace and conveys the inside of the furnace in order to heat-treat the metal product M. A carriage frame 2, a main refractory 3, and an exchange member 30 are provided, and the exchange member 30 can be easily separated.

台車フレーム２は鋼鉄製で、格子状に組まれた鋼材上に平板が取付けられていて、底面には移動用の車輪（またはレール）が設けられている。
主耐火物３は、台車フレーム２の上面全体に平坦状に上載されており、その上面に金属製品Ｍを載せる。なお、本実施形態における主耐火物３は、多数の煉瓦を並べて構成している。 The carriage frame 2 is made of steel, a flat plate is mounted on a steel material assembled in a lattice shape, and moving wheels (or rails) are provided on the bottom surface.
The main refractory 3 is placed flat on the entire top surface of the carriage frame 2, and the metal product M is placed on the top surface. In addition, the main refractory 3 in this embodiment comprises many bricks arranged side by side.

そして、交換部材３０は、取付部５と副耐火物６とで構成されている。
ここで、取付部５は、図１に示すように、台車フレーム２の外周端面に対して複数のボルト９（およびナット）といった締結部材によって着脱自在に取付けられている。また、副耐火物６は、取付部５の上面に、主耐火物３の外周端面に隣接するように固定している。副耐火物６の上面の位置は、主耐火物３の上面の位置と同一にしている。 The replacement member 30 includes the attachment portion 5 and the auxiliary refractory 6.
Here, as shown in FIG. 1, the attachment portion 5 is detachably attached to the outer peripheral end surface of the carriage frame 2 by fastening members such as a plurality of bolts 9 (and nuts). The auxiliary refractory 6 is fixed to the upper surface of the attachment portion 5 so as to be adjacent to the outer peripheral end face of the main refractory 3. The position of the upper surface of the auxiliary refractory 6 is the same as the position of the upper surface of the main refractory 3.

また、本実施形態における副耐火物６は、取付部５の上面に溶接（またはボルト）で固定した鋼鉄製の受金物７と、受金物７の露出面を覆うように打設されたキャスタブル８とで構成している。
キャスタブル８は、シリカおよびアルミナを含む（シリカ、アルミナのうちいずれか一つを含むものでもよい）もので、受金物７の上面と主耐火物３の外周面側、およびそれに対向する炉体１１の内周面側に連続的に設けている。なお、キャスタブル８の、炉体１１の内周面側は、取付部５の外周端面（垂直面）を覆うように垂下設している。 In addition, the auxiliary refractory 6 in the present embodiment includes a steel receiving object 7 fixed to the upper surface of the mounting portion 5 by welding (or bolts), and a castable 8 that is placed so as to cover the exposed surface of the receiving object 7. It consists of and.
The castable 8 includes silica and alumina (may include any one of silica and alumina). The upper surface of the metal receiving object 7 and the outer peripheral surface side of the main refractory 3 and the furnace body 11 facing the upper surface. Are provided continuously on the inner peripheral surface side. Note that the inner peripheral surface side of the furnace body 11 of the castable 8 is suspended so as to cover the outer peripheral end surface (vertical surface) of the mounting portion 5.

さらに、この金属製品加熱用台車１は、台車フレーム２の外周端面に凸段部２ａを形成し、交換部材３０の取付部５の内周端面に、凸段部２ａに係合する凹段部５ａを形成している。   Further, this metal product heating cart 1 has a convex step 2a formed on the outer peripheral end surface of the cart frame 2, and a concave step portion engaged with the convex step 2a on the inner peripheral end surface of the mounting portion 5 of the replacement member 30. 5a is formed.

なお、炉体１１の下面に、キャスタブル８と炉体１１との間の間隙Ｇから熱が放出するのを防止するためのシール装置１０を設けている。このシール装置１０は、シリンダー１０ａとシール材１０ｂとで構成しており、通常時ではロッドを伸長させてシール材１０ｂで間隙Ｇの下端を塞いでいる。交換部材３０を交換する際などには、ロッドを収縮させて間隙Ｇから離脱させるようになっている。   A sealing device 10 is provided on the lower surface of the furnace body 11 to prevent heat from being released from the gap G between the castable 8 and the furnace body 11. The sealing device 10 is composed of a cylinder 10a and a sealing material 10b, and normally, a rod is extended and the lower end of the gap G is closed with the sealing material 10b. When exchanging the exchange member 30, the rod is contracted and detached from the gap G.

このように構成された本実施形態に係る金属製品加熱用台車１は、台車フレーム２から容易に取外可能な交換部材３０を備えているので、副耐火物６の補修を容易かつ短時間で行うことができる。
例えば、副耐火物６を構成する受金物７が傾いたり、キャスタブル８が欠損等した場合、交換部材３０を、ボルト９を外して台車フレーム２から取り外した後、それに代わる新たな交換部材３０を台車フレーム２にボルト９で取付けることによって対応することができる。従って、副耐火物６の補修を、極めて容易かつ短時間に終えることができ、また、補修に要する費用を削減し、また、補修時に加熱炉等を停止させる必要もないので、生産性を低下させることもない。 Since the metal product heating cart 1 according to the present embodiment configured as described above includes the replacement member 30 that can be easily detached from the cart frame 2, the auxiliary refractory 6 can be repaired easily and in a short time. It can be carried out.
For example, when the metal receiving material 7 constituting the auxiliary refractory 6 is tilted or the castable 8 is missing, the replacement member 30 is removed from the carriage frame 2 by removing the bolt 9 and then replaced with a new replacement member 30 instead. This can be dealt with by attaching the bolt 9 to the carriage frame 2. Therefore, the repair of the auxiliary refractory 6 can be completed extremely easily and in a short time, the cost required for the repair can be reduced, and the heating furnace or the like does not need to be stopped at the time of repair, so the productivity is reduced. I will not let you.

なお、新たな交換部材３０を取付けた後、副耐火物６と主耐火物３との間に空隙Ｓが形成される場合は、その空隙Ｓにセラミックファイバーなどの充填材やシール材を詰め込むことによって、主耐火物３の横滑りを確実に防止することができる。   When a gap S is formed between the auxiliary refractory 6 and the main refractory 3 after the new replacement member 30 is attached, the gap S is filled with a filler such as ceramic fiber or a sealing material. Therefore, it is possible to reliably prevent the main refractory 3 from slipping.

また、この金属製品加熱用台車１は、主耐火物３を、煉瓦で構成しているので、煉瓦の持つ優れた耐火性により、高い耐久性を維持することができる。   Moreover, since the metal refractory cart 1 is composed of bricks as the main refractory 3, high durability can be maintained due to the excellent fire resistance of the bricks.

また、副耐火物６を、取付部５の上面に固定した受金物７と、その露出面を覆うキャスタブル８とで構成しているので、受金物７（鋼鉄）が持つ高い剛性によって主耐火物３が台車フレーム２から横滑りするのを防止し、また、キャスタブル８によって受金物７が高熱によって変形等するのを防止する。
これにより、副耐火材の耐久性を高めることができる。 Further, since the auxiliary refractory 6 is composed of a metal receiver 7 fixed to the upper surface of the mounting portion 5 and a castable 8 that covers the exposed surface, the main refractory is provided by the high rigidity of the metal receiver 7 (steel). 3 is prevented from slipping from the carriage frame 2 and the castable 8 prevents the received article 7 from being deformed by high heat.
Thereby, durability of a subsidiary refractory material can be improved.

また、台車フレーム２の外周端面に凸段部２ａを形成し、取付部５の内周端面に、凸段部２ａに係合する凹段部５ａを形成しているので、凸段部２ａと凹段部５ａを係合させた状態でボルト９を着脱することができる。
従って、交換部材３０を容易に交換することができるので、副耐火物６の補修をさらに容易かつ短時間で行うことができる。 Moreover, since the convex step part 2a is formed in the outer peripheral end surface of the trolley | bogie frame 2, and the concave step part 5a engaged with the convex step part 2a is formed in the inner peripheral end surface of the attachment part 5, the convex step part 2a and The bolt 9 can be attached and detached while the concave step portion 5a is engaged.
Therefore, since the replacement member 30 can be easily replaced, the auxiliary refractory 6 can be repaired more easily and in a short time.

なお、本実施形態では、交換部材３０を、図１に示す、キャスタブル８と同じ長さで、長手方向に複数分割して小型化した状態で設けている。こうすることによって、交換部材３０の取扱いをさらに一層容易なものとすることができる。すなわち、副耐火物６が損傷した部分の交換部材３０のみを長手方向全体ではなく長手方向の短い範囲で交換することができるので、交換作業が容易であり、経済的でもある。   In the present embodiment, the replacement member 30 is provided in the same length as the castable 8 shown in FIG. By doing so, handling of the replacement member 30 can be made even easier. That is, since only the replacement member 30 in the damaged part of the auxiliary refractory 6 can be replaced in a short range in the longitudinal direction instead of the entire longitudinal direction, the replacement work is easy and economical.

なお、本実施形態における取付部５は鋼鉄板で形成して、作業者の手を挿入することのできる大きさの中空部Ｈを形成している。これにより、手作業によるボルト９の着脱を容易に行うことができる。また、取付部５の上面と下面を、台車フレーム２の上面と下面にそれぞれ面一に設定し、通常時では、取付部５を台車の一部として機能させている。   In addition, the attaching part 5 in this embodiment is formed with the steel plate, and forms the hollow part H of the magnitude | size which can insert an operator's hand. Thereby, the bolt 9 can be easily attached and detached manually. Further, the upper surface and the lower surface of the attachment portion 5 are set to be flush with the upper surface and the lower surface of the carriage frame 2, respectively, so that the attachment portion 5 functions as a part of the carriage at normal times.

なお、この金属製品加熱用台車１は、主耐火物３と副耐火物６を、同一の耐火材で構成することもできる。こうすることによって、例えば、ストックする耐火材の種類を少なくして、経済性を高めることができる。   In this metal product heating cart 1, the main refractory 3 and the auxiliary refractory 6 can be made of the same refractory material. By doing so, for example, the types of refractory materials to be stocked can be reduced, and the economic efficiency can be improved.

また、本実施形態における副耐火物６は、取付部５の上面に溶接（またはボルト）で固定した鋼鉄製の受金物７と、受金物７の露出面を覆うように打設されたキャスタブル８とで構成したが、副耐火物６の全体を、同一の耐火材で構成することもできる。
これによれば、鋼鉄製の受金物７が省かれるので、副耐火物６の製造を容易とし、経済性を高めることができる。 In addition, the auxiliary refractory 6 in the present embodiment includes a steel receiving object 7 fixed to the upper surface of the mounting portion 5 by welding (or bolts), and a castable 8 that is placed so as to cover the exposed surface of the receiving object 7. However, the entire auxiliary refractory 6 can be made of the same refractory material.
According to this, since the steel receiving material 7 is omitted, the production of the auxiliary refractory 6 can be facilitated and the economy can be improved.
