Description

炉内搬送装置及び加熱炉In-furnace transfer apparatus and heating furnace
 本発明は、炉内において被処理物を搬送させる炉内搬送装置及びこのような炉内搬送装置を備えた加熱炉に関するものである。特に、炉内搬送装置により炉内において被処理物を搬送させるにあたり、被処理物をその搬送方向に沿って炉床の上方に設けられた固定ビームの上を順々に移動させて搬送させるにあたり、被処理物の搬送方向に沿って設けられた移動ビームを、移動フレームにより上下方向及び送り方向に往復移動させてウォーキング動作させ、この移動ビームにより被処理物を固定ビームの上を順々に移動させて搬送させる従来のウォーキングビーム式の炉内搬送装置に比べて、その設備が非常に簡単で、全体としてのコストを大幅に低減できると共に、メンテナンス等も容易に行えるようにした点に特徴を有するものである。 The present invention relates to an in-furnace transfer device for transferring an object to be treated in a furnace and a heating furnace provided with such an in-furnace transfer device. In particular, when the object to be treated is conveyed in the furnace by the in-furnace conveyance device, the object to be treated is sequentially moved and conveyed along the conveyance direction on the fixed beam provided above the hearth. The moving beam provided along the transport direction of the object is reciprocated in the up and down direction and the feed direction by the moving frame to make walking motion, and the object is sequentially moved on the fixed beam by the moving beam. Compared with the conventional walking beam type in-furnace transfer device that moves and transports, its facilities are very simple, the overall cost can be greatly reduced, and maintenance etc. can be easily performed. The
 従来から、加熱炉等においては、鋼片、鋼板等の被処理物を炉内において順々に搬送させて連続的に処理することが行われており、このように被処理物を炉内において順々に搬送させる炉内搬送装置としては、ウォーキングビーム式のものが広く利用されている。 Conventionally, in heating furnaces and the like, workpieces such as steel pieces and steel plates have been sequentially transported in the furnace and continuously treated, and thus the workpieces are treated in the furnace A walking beam type is widely used as an in-furnace transfer device for transferring sequentially.
 ここで、ウォーキングビーム式の炉内搬送装置においては、一般に、特許文献1~4等に示されるように、炉内に設けられた炉床の上に支持部材を介して被処理物の搬送方向に沿った固定ビームを被処理物の搬送方向と交差する方向に所要間隔を介して複数設けると共に、上記の炉床の下方に設けられた移動フレームから炉床に設けられた貫通部を通して炉床の上方に突出された支持部材に、被処理物の搬送方向に沿って炉の略全長に伸びた移動ビームを保持させて、複数の移動ビームを被処理物の搬送方向と交差する方向に所要間隔を介して設けている。 Here, in the walking beam type in-furnace transfer apparatus, generally, as shown in Patent Documents 1 to 4, the transfer direction of the object to be processed through the support member on the hearth provided in the furnace. While providing a plurality of fixed beams along the direction through the required space in the direction crossing the transport direction of the object to be processed, the hearth through the penetration portion provided in the hearth from the moving frame provided below the hearth The movable beam extended substantially over the entire length of the furnace along the transport direction of the object is held by the support member projecting upward, and the plurality of movable beams are required in the direction crossing the transport direction of the object It is provided via an interval.
 そして、上記のウォーキングビーム式の炉内搬送装置においては、移動フレームをウォーキングビーム駆動手段に支持させ、このウォーキングビーム駆動手段により上記の移動フレームを駆動させて、移動フレームに設けられた各移動ビームを上下方向及び送り方向に往復移動させてウォーキング動作(矩形運動)させ、被処理物を各移動ビームにより固定ビームの上を順々に移動させて、被処理物を炉内において順々に移動させるようにしている。 Then, in the walking beam type in-furnace transfer apparatus described above, the moving frame is supported by the walking beam driving means, and the moving beam is driven by the walking beam driving means to move each moving beam provided on the moving frame. Is moved back and forth in the up and down direction and in the feed direction to make walking motion (rectangular motion), the object to be treated is sequentially moved on the fixed beam by each moving beam, and the object to be treated is sequentially moved in the furnace I am trying to
 ここで、上記のようにウォーキングビーム駆動手段によって移動フレームに設けられた各移動ビームをウォーキング動作させる場合、このウォーキングビーム駆動手段が大型化すると共に、加熱炉等における炉床の下に上記のような移動フレームやウォーキングビーム駆動手段を設けるためには、炉床の下の掘り込み深さを大きくすることが必要になった。このため、このような設備に多大なコストが必要になると共に、ウォーキングビーム駆動手段を駆動させるのに大きな動力が必要となり、ランニングコストも高くつくという問題があった。 Here, in the case where each moving beam provided on the moving frame is walked by the walking beam drive means as described above, the walking beam drive means is enlarged and the above-mentioned movement is made under the hearth in the heating furnace etc. In order to provide a moving frame and walking beam drive means, it has become necessary to increase the digging depth below the hearth. As a result, such equipment requires a great deal of cost, a large power is required to drive the walking beam drive means, and there is a problem that the running cost is also high.
 また、被処理物を加熱させる加熱炉に上記のようなウォーキングビーム式の炉内搬送装置を設けた場合、上記の各移動ビームが過剰に加熱されて変形したり、損傷したりするのを防止するため、各移動ビームを水冷させるようにしている。 In addition, when the walking beam type in-furnace transfer apparatus as described above is provided in a heating furnace for heating an object to be processed, it is possible to prevent each moving beam from being excessively heated and deformed or damaged. In order to do this, each moving beam is water-cooled.
 しかし、ウォーキングビーム式の炉内搬送装置においては、上記のように各移動ビームを被処理物の搬送方向に沿って炉の略全長に伸びるように設けているため、このように炉の略全長に伸びた各移動ビーム全体を水冷させるのに、大きな水冷設備が必要になると共に、水冷ロスも大きくなる等の問題があった。 However, in the walking beam type in-furnace transfer apparatus, as described above, each moving beam is provided to extend substantially the entire length of the furnace along the transfer direction of the object to be treated. In order to water-cool the entire moving beams, it is necessary to use a large water-cooling facility and to increase the water-cooling loss.

 本発明は、炉内において被処理物を搬送させる炉内搬送装置及びこのような炉内搬送装置を備えた加熱炉において、ウォーキングビーム式の炉内搬送装置を用いた場合における上記のような様々な問題を解決することを課題とするものである。 The present invention relates to an in-furnace transfer apparatus for transferring an object to be processed in a furnace and a heating furnace provided with such in-furnace transfer apparatus as described above when using a walking beam type in-furnace transfer apparatus. To solve the problems of
 すなわち、本発明においては、加熱炉等の炉内において、炉内搬送装置により被処理物を炉床の上方に設けられた固定ビームの上を順々に移動させて搬送させるにあたり、上記のようなウォーキングビーム式の炉内搬送装置に比べて、その設備が非常に簡単になり、全体としてのコストを大幅に低減できると共に、メンテナンス等も容易に行えるようにすることを課題とするものである。 That is, in the present invention, in the furnace, such as a heating furnace, the above-described object is transferred by the in-furnace transfer device one by one and moved in order on the fixed beam provided above the hearth. It is an object of the present invention to simplify the equipment and greatly reduce the overall cost as well as facilitate maintenance, etc., as compared with the conventional walking beam type in-furnace transfer apparatus. .
 本発明に係る炉内搬送装置においては、上記のような課題を解決するため、炉床の上方に被処理物の搬送方向に沿った固定ビームが被処理物の搬送方向と交差する方向に所要間隔を介して複数設けられると共に、被処理物の搬送方向に沿って上記の炉床を貫通する搬送案内溝が被処理物の搬送方向と交差する方向に所要間隔を介して複数設けられ、上記の炉床の下において上記の搬送案内溝に沿って被処理物の搬送方向に走行するカートに、上記の搬送案内溝を通して上方に突出されて昇降する昇降保持部が設けられてなる炉内搬送装置であって、カートに設けられた上記の昇降保持部を上昇させて、上記の固定ビームに保持された被処理物をこの昇降保持部に保持させると共に、上記のカートを走行させて昇降保持部に保持された被処理物を固定ビームの所定位置まで搬送させるようにした。 In the transfer apparatus according to the present invention, in order to solve the above problems, a fixed beam along the transfer direction of the object to be processed is required above the hearth in a direction intersecting the transfer direction of the object to be processed A plurality of transport guide grooves are provided at intervals along the transport direction of the workpiece, and a plurality of transport guide grooves penetrating the hearth along the transport direction of the workpiece are provided at predetermined intervals in the direction intersecting the transport direction of the workpiece, In-furnace transfer where a cart that travels in the transfer direction of the object along the transfer guide groove below the hearth of the furnace is provided with a lift holder projecting upward through the transfer guide groove and moving up and down The apparatus is configured to raise the elevating holder provided on the cart to hold the object held by the fixed beam on the elevating holder, and run the cart to raise and lower the cart. Processing held in the department And so as to transport the to a predetermined position of the fixed beam.
 このようにすると、従来のウォーキングビーム式の炉内搬送装置のように、被処理物の搬送方向に沿って炉の略全長に伸びた複数の移動ビームを保持させる移動フレームを被処理物の搬送方向に沿って炉床の下方に設けると共に、この移動フレームを移動させて各移動ビームを上下方向及び送り方向に往復移動させてウォーキング動作させる大型のウォーキングビーム駆動手段を設ける必要がなくなる。 By doing this, as in the conventional walking beam type in-furnace transfer apparatus, the transfer frame for holding the plurality of moving beams extending substantially the entire length of the furnace along the transfer direction of the process object is transferred to the process object It is not necessary to provide along the direction below the hearth and to provide a large walking beam drive means for moving the moving frame to reciprocate each moving beam in the vertical direction and the feed direction for walking operation.
 また、上記のように被処理物をカートに設けられた昇降保持部に保持させるため、ウォーキングビーム式の炉内搬送装置のように、炉の略全長に伸びた複数の移動ビームを設ける必要もなくなり、炉内の構造が簡素化される。 Further, as described above, in order to hold the object to be processed in the lifting and lowering holding portion provided on the cart, it is also necessary to provide a plurality of moving beams extending substantially the entire length of the furnace like a walking beam type in-furnace transfer device. And the structure in the furnace is simplified.
 ここで、この炉内搬送装置においても、被処理物を保持する上記の昇降保持部が炉内において過剰に加熱されて、変形したり、損傷したりするのを防止するため、この昇降保持部を冷却させる冷却手段を設けることが好ましい。 Here, also in the transfer apparatus in the furnace, the elevating and holding portion for holding the object to be treated is prevented from being excessively heated in the furnace to be deformed or damaged. Preferably, a cooling means is provided for cooling the
 また、上記のようにカートに設けられた昇降保持部を上昇させて、固定ビームに保持された被処理物をこの昇降保持部に保持させ、上記のカートを走行させて昇降保持部に保持された被処理物を固定ビームの所定位置まで搬送させるにあたっては、上記のカートを各搬送案内溝に対応して被処理物の搬送方向と交差する方向に複数設けるようにすることができる。また、被処理物の搬送方向に所要間隔を介して上記のカートを複数設けるようにすることもできる。 Further, as described above, the elevating and holding unit provided on the cart is raised, and the object held by the fixed beam is held by the elevating and holding unit, and the cart is caused to travel and held by the elevating and holding unit. In order to convey the object to be processed to a predetermined position of the fixed beam, a plurality of the above carts can be provided in a direction intersecting the conveyance direction of the object corresponding to each conveyance guide groove. In addition, a plurality of the above-mentioned carts can be provided at predetermined intervals in the transport direction of the object to be processed.
 そして、本発明に係る加熱炉においては、被処理物を炉内において順々に搬送させて連続的に加熱するにあたり、上記のような炉内搬送装置を用いるようにした。 Then, in the heating furnace according to the present invention, the above-described in-furnace transfer apparatus is used to sequentially transfer and sequentially heat the objects to be processed in the furnace.
 また、本発明に係る加熱炉においては、被処理物を加熱炉内に搬入させる加熱炉の搬入部側に上記の搬送案内溝と対応するようにして搬入側壁面案内溝を設け、この搬入側壁面案内溝を通して、上記のカートを搬入部側における加熱炉の外部に導くようにすることができる。このようにすると、カートを搬入部側における加熱炉の外部に導いて、カートの補修や交換を行うことができる。 Further, in the heating furnace according to the present invention, a carrying-in side wall guide groove is provided on the carrying-in portion side of the heating furnace for carrying the object to be processed into correspondence with the above-mentioned transfer guide groove. It is possible to guide the above-mentioned cart to the outside of the heating furnace on the loading unit side through the wall surface guiding groove. In this way, the cart can be guided to the outside of the heating furnace on the loading unit side, and the cart can be repaired or replaced.
 さらに、被処理物を加熱炉内に搬入させる搬入部に上記の搬送案内溝及び搬入側壁面案内溝と対応するようにして搬入用案内溝を設け、この搬入用案内溝を通してカートに設けられた上記の昇降保持部を上昇させて、搬入部における被処理物をこの昇降保持部に保持させ、この搬入用案内溝及び搬入側壁面案内溝を通して上記の昇降保持部に保持された被処理物を加熱炉内に搬入させるようにすることができる。このようにすると、通常は別設備として設置される被処理物の搬入装置が不要になる。 Furthermore, a loading guide groove is provided in the loading section for loading the object to be processed into the heating furnace so as to correspond to the above-described transport guide groove and loading side wall surface guide groove, and the cart is provided with the loading guide groove. The elevating and holding unit is raised to hold the object to be treated in the loading unit in the elevating and holding unit, and the object to be processed held by the elevating and holding unit through the guide groove for carrying in and the side wall guide groove for carrying in It can be made to carry in in a heating furnace. If this is done, a loading device for the object to be processed, which is usually installed as a separate facility, becomes unnecessary.
 また、本発明に係る加熱炉においては、被処理物を加熱炉外に搬出させる加熱炉の搬出部側に上記の搬送案内溝と対応するようにして搬出側壁面案内溝を設け、この搬出側壁面案内溝を通して、上記のカートを搬出部側における加熱炉の外部に導くようにすることができる。このようにすると、カートを搬出部側における加熱炉の外部に導いて、カートの補修や交換を行うことができる。 Further, in the heating furnace according to the present invention, a discharge side wall surface guide groove is provided on the unloading portion side of the heating furnace for unloading the object to be processed to the outside of the heating furnace so as to correspond to the transfer guide groove. It is possible to lead the above-mentioned cart to the outside of the heating furnace on the unloading portion side through the wall surface guide groove. In this way, the cart can be guided to the outside of the heating furnace on the discharge unit side, and the cart can be repaired or replaced.
 さらに、被処理物を加熱炉外に搬出させる搬出部に上記の搬送案内溝及び搬出側壁面案内溝と対応するようにして搬出用案内溝を設け、カートにおける昇降保持部に保持された被処理物を、上記の搬出側壁面案内溝及びこの搬出用案内溝を通して加熱炉外に搬出させるようにすることができる。このようにすると、通常は別設備として設置される被処理物の搬出装置が不要になる。 Furthermore, the unloading guide groove is provided at the unloading portion for unloading the object to be processed out of the heating furnace so as to correspond to the conveying guide groove and the unloading side wall surface guide groove described above. The object can be carried out of the heating furnace through the above-mentioned discharge side wall surface guide groove and the discharge guide groove. If this is done, there will be no need to carry out the object to be processed that is normally installed as a separate facility.
 本発明における炉内搬送装置においては、上記のように炉床の下において被処理物の搬送方向に走行するカートに搬送案内溝を通して上方に突出されて昇降する昇降保持部を設け、この昇降保持部を上昇させて、固定ビームに保持された被処理物をこの昇降保持部に保持させると共に、カートを走行させて昇降保持部に保持された被処理物を固定ビームの所定位置まで移動させて、被処理物を炉内において順々に搬送させるようにしたため、従来のウォーキングビーム式の炉内搬送装置のように、炉床の下方に、複数の移動ビームを保持させる移動フレームや、この移動フレームを駆動させて各移動ビームをウォーキング動作させるウォーキングビーム駆動手段のような大型の装置を設ける必要がなくなる。 In the transfer apparatus in the furnace according to the present invention, as described above, the cart traveling in the transfer direction of the object under the hearth is provided with a lift holding portion projecting upward through the transfer guide groove and moving up and down. The unit is raised to hold the object held by the fixed beam on the elevating holder, and the cart is made to travel to move the object held by the elevating holder to a predetermined position of the fixed beam. Since the objects to be treated are sequentially transported in the furnace, a moving frame for holding a plurality of moving beams below the hearth, and this movement as in the conventional walking beam type in-core transfer system There is no need to provide a large device such as a walking beam drive that drives the frame to walk each moving beam.
 この結果、本発明における炉内搬送装置を使用すると、加熱炉等における炉床の下の掘り込み深さを小さくすることができ、設備に要するコストが大きく低減されると共にランニングコストも少なくすみ、さらに掘り込んだ床面にはカート用のレールを敷設しただけの構造となるため、広い空間を確保することができ、メンテナンス等も容易に行えるようになる。 As a result, when using the in-furnace transfer apparatus according to the present invention, the digging depth under the hearth in the heating furnace etc. can be reduced, the cost required for the equipment can be greatly reduced, and the running cost can be reduced. Further, since the structure is simply constructed by laying rails for carts on the floor surface which has been dug-in, a large space can be secured and maintenance can be easily performed.
 また、本発明における炉内搬送装置においては、カートに設けられた昇降保持部に被処理物を保持させた状態で、カートを走行させて昇降保持部に保持された被処理物を固定ビームの所定位置まで搬送させるようにするため、昇降保持部は被処理物を保持できる程度の長さであればよく、従来のウォーキングビーム式の炉内搬送装置における移動ビームのように、被処理物の搬送方向に沿って炉の略全長に伸びるように設ける必要がなくなると共に、このような昇降保持部を冷却させる場合、上記の移動ビームのように大きな水冷設備が必要になったり、水冷ロスが大きくなったりすることもなくなる。 Further, in the transfer apparatus in a furnace according to the present invention, in a state in which the object to be treated is held by the elevating and holding unit provided in the cart, the object to be treated held by the elevating and holding unit is made to move In order to be transported to a predetermined position, the elevating and holding unit may have a length sufficient to hold the object to be treated, and like the moving beam in the conventional walking beam type in-furnace transfer device, There is no need to extend the furnace along the transport direction so as to extend substantially the entire length of the furnace, and when cooling such a lift holder, a large water cooling facility like the above moving beam is required, and the water loss is large. There is no need to become
 また、本発明における加熱炉において、前記のように搬送案内溝と対応するようにして搬入側壁面案内溝や搬出側壁面案内溝を設けると、この搬入側壁面案内溝や搬出側壁面案内溝を通して上記のカートを加熱炉の外に導くことができるようになり、加熱炉を停止させて冷却させなくても、カートのメンテナンスや交換等が簡単に行えるようになる。 Further, in the heating furnace according to the present invention, when the carry-in side wall surface guide groove and the carry-out side wall surface guide groove are provided to correspond to the transport guide grooves as described above, through the carry-in side wall surface guide groove and the carry-out side wall surface guide groove. The cart described above can be introduced outside the heating furnace, and maintenance and replacement of the cart can be easily performed without stopping the heating furnace and cooling it.
