Description

本発明は、先行金属板の尾端部と後行金属板の先端部との接合時における先，後行金属板の幅揃え装置及び方法と該幅揃え方法及び装置が適用される連続圧延設備に関する。   The present invention relates to a front and rear metal plate width aligning apparatus and method and a continuous rolling facility to which the width aligning method and apparatus are applied at the time of joining the tail end portion of the preceding metal plate and the front end portion of the subsequent metal plate. About.

例えば連続熱間圧延設備では、金属板が粗圧延機で粗圧延されてコイルボックスに巻き取られ、このコイルボックスから巻き出されて仕上圧延機で仕上げ圧延される際に、コイルボックスから巻き出された先行金属板の尾端部と後行金属板の先端部とが接合装置で接合されて仕上圧延機により連続して仕上げ圧延され、所望の厚さの金属板（圧延鋼板）を得るようになっている。このように仕上げ圧延を連続して行うためには、高速で先，後行金属板同士を接合する必要があり、従来では種々の技術が提案されている。   For example, in a continuous hot rolling facility, when a metal plate is roughly rolled by a roughing mill and wound around a coil box, and then unwound from this coil box and finish-rolled by a finishing mill, it is unwound from the coil box. The tail end portion of the preceding metal plate and the tip end portion of the succeeding metal plate are joined by a joining device and are continuously finish-rolled by a finish rolling mill to obtain a metal plate (rolled steel plate) having a desired thickness. It has become. Thus, in order to perform finish rolling continuously, it is necessary to join the preceding and succeeding metal plates at a high speed, and various techniques have been conventionally proposed.

例えば、特許文献１では、先行材後端部と後行材先端部を切断する切断機と、切断後の前記後端部と先端部を加熱・圧接する接合機とからなる鋼片の接合装置において、鋼片を両側から挾持してセンタリングするサイドガイド装置を切断機入出側と接合機入出側に配置して、鋼片をセンタリングする装置及び方法が開示されている。また、本装置及び方法によれば、切断、加熱、圧接時にセンタリングできるので、センターずれや口開きといった突合せ不良に起因する接合失敗を未然に確実に防止することができると言及されている。   For example, in Patent Document 1, a steel piece joining apparatus comprising a cutting machine that cuts the rear end portion of the preceding material and the front end portion of the succeeding material, and a joining machine that heats and presses the rear end portion and the front end portion after cutting. Discloses a device and a method for centering a steel slab by arranging side guide devices for gripping and centering a steel slab from both sides on a cutting machine input / output side and a joining machine input / output side. Further, according to the present apparatus and method, it can be said that centering can be performed at the time of cutting, heating, and pressure welding, so that it is possible to reliably prevent a joining failure due to a butt failure such as a center shift or a mouth opening.

また、特許文献２では、先行圧延材の後端部と後行圧延材の先端部を突合せて接合する装置において、先行圧延材と後行圧延材を独立に圧延設備中心（パスセンター）に保持する油圧サイドガイド装置を設けることが開示されている。   Moreover, in patent document 2, in the apparatus which butt-joins and joins the rear-end part of a preceding rolling material, and the front-end | tip part of a succeeding rolling material, a preceding rolling material and a following rolling material are independently hold | maintained in a rolling equipment center (pass center). It is disclosed that a hydraulic side guide device is provided.

ところで、一般に、コイルボックスから巻き出された先行金属板の尾端近くや後行金属板の先端近くには、部分的な曲がりが生じる場合がある。   By the way, in general, a partial bend may occur near the tail end of the preceding metal plate unwound from the coil box or near the tip end of the succeeding metal plate.

ところが、前述した特許文献１や特許文献２などに開示されているように、サイドガイド装置がセンタリング機能だけでは、先行金属板の尾端近くや後行金属板の先端近くに曲がりがある場合に接合部に幅ずれ状態が生じる。   However, as disclosed in Patent Document 1 and Patent Document 2 described above, when the side guide device has only a centering function, there is a bend near the tail end of the preceding metal plate or the tip end of the following metal plate. A width shift state occurs at the joint.

例えば、接合方式が先，後行金属板の端部間を重ね合せた状態の剪断過程において接合を完了する方式に例をとっても、図７に示すように、先行金属板１００Ａの尾端近くや後行金属板１００Ｂの先端近くに部分的（局部的）な曲がりがある場合（図７の（ａ）参照）、サイドガイド装置の第１〜第４縦ローラ対１０１ａ〜１０１ｄにより先行金属板１００Ａと後行金属板１００Ｂをセンタリングしつつ接合位置でその端部間を重ね合せた状態の剪断過程において接合を完了した場合（図７の（ｂ）→図７の（ｃ）参照）、接合部に幅ずれ状態（図７（ｃ）中の幅ずれ部イ，ロ参照）が生じるのである。この現象は、図７のように、前記部分的な曲がりの方向が異なる方向の場合は、特に顕著である。   For example, even if the joining method is an example in which joining is completed in a shearing process in which the end portions of the preceding and succeeding metal plates are overlapped, as shown in FIG. When there is a partial (local) bending near the tip of the trailing metal plate 100B (see FIG. 7A), the first to fourth vertical roller pairs 101a to 101d of the side guide device cause the leading metal plate 100A. When the joining is completed in the shearing process in which the end portions are overlapped at the joining position while centering the trailing metal plate 100B (see FIG. 7B → FIG. 7C), the joining portion Thus, a width deviation state (see width deviation portions a and b in FIG. 7C) occurs. This phenomenon is particularly remarkable when the partial bending directions are different as shown in FIG.

幅ずれ部イ，ロが生じたままでは、図８に示すように、仕上圧延機１０２の入側に配設されたサイドガイド装置のガイドプレート対１０３においては、先，後行金属板１００Ａ，１００Ｂの接合部通過時に幅ずれ部イ，ロとの干渉を回避するために、その間隔Ｌ1を拡げる必要が生じ、曲がり矯正の機能を果たすことができなくなるという問題点があった。 As shown in FIG. 8, in the guide plate pair 103 of the side guide device disposed on the entry side of the finish rolling mill 102, the first and second metal plates 100A, 100B widthwise shift unit Lee at junction passage, in order to avoid interference with the filtration, necessary to widen the distance L 1 occurs, there is a problem that can not perform the function of straightening.

また、仕上圧延機１０２の出側まで、各圧延機の入側にあるガイドプレート対１０３を先，後行金属板１００Ａ，１００Ｂの接合部が通過するたびに幅方向で接合部を拘束することがないので、曲がりを矯正することはできない。そして、この状態を仕上圧延機１０２の出側で巻き取るまでの間保持し、ガイドプレート対１０３との幅方向の干渉を回避する配慮を要するため、操業が複雑になるという問題点もあった。また、巻き取られたコイルの姿においても、先，後行金属板１００Ａ，１００Ｂの接合部に大きな段差を残すこととなり、幅ずれ状態が残る問題があった。   In addition, the joining portion is restrained in the width direction every time the joining portion of the succeeding metal plates 100A and 100B passes through the guide plate pair 103 on the entry side of each rolling mill until the exit side of the finish rolling mill 102. Because there is no, you can not correct the bend. And this state is held until it is wound on the exit side of the finish rolling mill 102, and it is necessary to consider interference in the width direction with the guide plate pair 103, so that there is a problem that the operation becomes complicated. . In addition, the wound coil also has a problem in that a large step is left at the joint between the preceding and succeeding metal plates 100A and 100B, and a width deviation state remains.

本発明は、上記実情に鑑みてなされたもので、先，後行金属板の接合位置における幅ずれを可及的に低減して接合部近傍の曲がり矯正が可能な先，後行金属板の幅揃え方法及び装置と連続圧延設備を提供することを目的とする。   The present invention has been made in view of the above circumstances, and it is possible to reduce the width deviation at the joining position of the preceding and succeeding metal plates as much as possible and to correct the bending near the joint portion. An object is to provide a width aligning method and apparatus and continuous rolling equipment.

上記目的を達成するための本発明に係る先，後行金属板の幅揃え方法は、パスライン方向の進行下で先行金属板の後端部と後行金属板の先端部を接合するのに先立って、先行金属板の後端部と後行金属板の先端部の接合位置における幅方向センター位置のずれを少なくするように、先行金属板と後行金属板の少なくとも一方を幅方向にずらすことを特徴とする。   In order to achieve the above object, according to the present invention, a width aligning method for a trailing metal plate is used to join the trailing end of a preceding metal plate and the leading end of a trailing metal plate in the progress of the pass line direction. Prior to shifting, at least one of the preceding metal plate and the succeeding metal plate is shifted in the width direction so as to reduce the shift of the center position in the width direction at the joining position of the rear end portion of the preceding metal plate and the leading end portion of the following metal plate. It is characterized by that.

また、前記幅方向にずらす量は、先行金属板の後端部又は後行金属板の先端部の曲がり状態を検出し、この検出結果から接合位置における幅方向センター位置のずれ量を求め、このずれ量に基づいて幅方向センター位置のずれを少なくするように調整するために求めた移動量であることを特徴とする。   Further, the amount of displacement in the width direction is detected by detecting the bent state of the rear end portion of the preceding metal plate or the front end portion of the subsequent metal plate, and the amount of displacement of the center position in the width direction at the joining position is obtained from this detection result. It is the amount of movement obtained in order to adjust so as to reduce the deviation of the center position in the width direction based on the deviation amount.

また、前記幅方向にずらす際に、先行金属板の全長部は略同一位置を進行させつつ後端部近くを曲げ、又は後行金属板の全長部は略同一位置を進行させつつ先端部近くを曲げることを特徴とする。   Further, when shifting in the width direction, the full length portion of the preceding metal plate is bent near the rear end portion while advancing substantially the same position, or the full length portion of the succeeding metal plate is moved near the front end portion while moving the substantially same position. It is characterized by bending.

また、前記曲げる量は、先行金属板又は後行金属板の弾性変形の範囲内としたことを特徴とする。   The amount of bending is within the range of elastic deformation of the preceding metal plate or the following metal plate.

また、前記接合するにあたって、先，後行金属板の端部間を重ね合せた状態の剪断過程において接合を完了する方式が用いられることを特徴とする。   In the joining, a method is used in which the joining is completed in a shearing process in which the end portions of the preceding and succeeding metal plates are overlapped.

また、前記幅方向にずらすにあたって、接合位置の手前に第１の縦ローラを配置し、かつ前記第１の縦ローラの反接合位置に第２の縦ローラを配置して、第２の縦ローラは全長部の幅位置を決めるようにし、第１の縦ローラは、先行金属板の後端部と後行金属板の先端部の接合位置の幅方向センター位置のずれを少なくするように、第２の縦ローラに対して幅方向にずらすことを特徴とする。   Further, when shifting in the width direction, a first vertical roller is disposed in front of the joining position, and a second vertical roller is disposed at the anti-joining position of the first vertical roller. Determines the width position of the full length portion, and the first vertical roller reduces the shift in the center position in the width direction of the joining position of the rear end portion of the preceding metal plate and the front end portion of the subsequent metal plate. It is characterized by shifting in the width direction with respect to the two vertical rollers.

上記目的を達成するための本発明に係る連続圧延設備は、パスライン方向の上流側から順次粗ミルとコイルボックスと接合装置と複数スタンドの圧延機により構成される仕上ミルとダウンコイラーとが備えられ、前記コイルボックスと仕上ミルとの間に前記先，後行金属板の幅揃え装置を介設したことを特徴とする。   In order to achieve the above object, a continuous rolling facility according to the present invention comprises a finishing mill and a downcoiler that are composed of a rough mill, a coil box, a joining device, and a multi-stand rolling mill sequentially from the upstream side in the pass line direction. In addition, a width aligning device for the first and subsequent metal plates is interposed between the coil box and the finishing mill.

本発明によれば、先，後行金属板を接合する際に、先行金属板の後端部と後行金属板の先端部の接合位置における幅方向センター位置のずれを少なくするように、先行金属板と後行金属板の少なくとも一方を幅方向にずらすようにしたので、先，後行金属板の接合位置における幅ずれを可及的に低減できる。   According to the present invention, when joining the preceding and succeeding metal plates, the leading and trailing metal plates are joined so as to reduce the shift of the center position in the width direction at the joining position of the trailing end of the preceding metal plate and the leading end of the succeeding metal plate. Since at least one of the metal plate and the succeeding metal plate is shifted in the width direction, the width deviation at the joining position of the preceding and succeeding metal plates can be reduced as much as possible.

このように先行金属板の後端部或いは後行金属板の先端部に存在する曲がりに起因した接合時の幅ずれを可及的に小さくしたので、仕上ミル入側に配置したサイドガイド装置により曲がりを矯正することが可能となり、接合位置を含めて全長の曲がりを少なくしながら仕上圧延が可能となる。   As described above, since the width deviation at the time of joining due to the bending existing at the rear end portion of the preceding metal plate or the front end portion of the succeeding metal plate is made as small as possible, the side guide device disposed on the finishing mill entry side It is possible to correct the bending, and finish rolling is possible while reducing the bending of the entire length including the joining position.

以下、本発明に係る先，後行金属板の幅揃え方法及び装置と連続圧延設備を実施例により図面を用いて詳細に説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method and an apparatus for width alignment of a preceding and subsequent metal plate and continuous rolling equipment according to the present invention will be described in detail with reference to the drawings.

図１は本発明の一実施例を示す連続（熱間）圧延設備の概略構成側面図、図２は同じく平面図、図３は同じく縦ローラ対部の正面図、図４は同じく制御ブロック図、図５は同じく接合時の作用説明図、図６は同じくサイドガイド装置における接合部通過時の作用説明図である。   1 is a schematic side view of a continuous (hot) rolling facility showing an embodiment of the present invention, FIG. 2 is a plan view, FIG. 3 is a front view of a pair of vertical rollers, and FIG. 4 is a control block diagram. FIG. 5 is an explanatory view of the action at the time of joining, and FIG. 6 is an explanatory view of the action at the time of passing through the joint in the side guide device.

図１及び図２に示すように、本実施例の連続（熱間）圧延設備は、上流側から粗圧延機（粗ミル）１、コイルボックス２、接合装置３、複数スタンドの圧延機により構成される仕上圧延機（仕上ミル）４及びダウンコイラー５が備えられている。   As shown in FIGS. 1 and 2, the continuous (hot) rolling equipment of this embodiment is composed of a rough rolling mill (coarse mill) 1, a coil box 2, a joining device 3, and a multi-stand rolling mill from the upstream side. A finishing mill (finishing mill) 4 and a down coiler 5 are provided.

粗ミル１で粗圧延された後行金属板（後行シートバー）６はコイルボックス２のコイラーに巻き取られ、粗ミル１と仕上ミル４の走行速度の差が調整される。コイルボックス２のコイラーから巻き出された後行シートバー６の先端部（必要に応じてクロップシャー７によりクロップが切断される）が接合装置３の重ね装置８で先行金属板（先行シートバー）９の後端部（必要に応じてクロップシャー７によりクロップが切断される）に重ね合わされる。   The succeeding metal plate (following sheet bar) 6 roughly rolled by the rough mill 1 is wound around the coiler of the coil box 2, and the difference in travel speed between the rough mill 1 and the finishing mill 4 is adjusted. The leading end of the succeeding sheet bar 6 unwound from the coiler of the coil box 2 (the crop is cut by the crop shear 7 as necessary) is the preceding metal plate (leading sheet bar) by the stacking device 8 of the joining device 3. 9 is superimposed on the rear end portion (the crop is cut by the crop shear 7 as required).

後行シートバー６の先端部と先行シートバー９の後端部が接合装置３の接合機１０で接合され、接合部のクロップがクロップ処理装置１２で切断処理される。接合装置３で接合されて連続状態となったシートバー１１は、仕上ミル４に送られる。   The leading end of the succeeding sheet bar 6 and the trailing end of the preceding sheet bar 9 are joined by the joining machine 10 of the joining device 3, and the crop at the joined portion is cut by the crop processing device 12. The sheet bar 11 joined by the joining device 3 and brought into a continuous state is sent to the finishing mill 4.

接合装置３は、先行シートバー９の後端部と後行シートバー６の先端部とを走行中に接合する構成で、短時間で接合が可能な短時間接合装置となっている。そして、走行中に接合を実施するために、接合機１０がシートバーの走行に追従して移動する構成や、接合機１０がシートバーの走行に追従して揺動する構成が適用可能である。   The joining device 3 is configured to join the rear end portion of the preceding seat bar 9 and the front end portion of the succeeding seat bar 6 during traveling, and is a short-time joining device capable of joining in a short time. In order to perform joining during traveling, a configuration in which the joining machine 10 moves following the traveling of the seat bar or a configuration in which the joining machine 10 swings following the traveling of the seat bar is applicable. .

例えば、本実施例における接合装置３の接合機１０は、先行シートバー９の後端部と後行シートバー６の先端部との重ね合せ部を挟みその両側から押し込んで剪断しながら接合する一対の剪断刃を有する接合機構となっている。   For example, the joining machine 10 of the joining apparatus 3 in the present embodiment is a pair that joins while pressing and shearing the overlapping portion of the trailing end portion of the preceding sheet bar 9 and the leading end portion of the succeeding seat bar 6 from both sides. This is a joining mechanism having a shear blade.

仕上ミル４に送られたシートバー１１は複数スタンドの圧延機により順次熱間圧延されて所望の板厚に仕上圧延され、仕上ミル４を出たシートバー１１はダウンコイラー５に巻き取られる。ここで、ダウンコイラー５の前に図示しない分割シャーが設置され、仕上ミル４の前で接合されたシートバー１１は、該分割シャーによって、分割されつつ、ダウンコイラー５によって巻き取られるようになっている。   The sheet bar 11 sent to the finishing mill 4 is successively hot-rolled by a plurality of stand rolling mills and finish-rolled to a desired plate thickness. Here, a split shear (not shown) is installed in front of the down coiler 5, and the sheet bar 11 joined in front of the finishing mill 4 is wound by the down coiler 5 while being split by the split shear. ing.

図中の符号で、１５は仕上ミル４の入側に設けられたクロップシャー、１６はクロップシャー１５のパスライン上流側に配置されたエッジヒータ、１７はエッジヒータ１６のパスライン下流側に近接して配置されたバーヒータ、１８は接合装置３のパスライン上流側に近接して配置されたデスケーラである。   In the figure, reference numeral 15 denotes a crop shear provided on the entry side of the finishing mill 4, 16 denotes an edge heater disposed on the upstream side of the pass line of the crop shear 15, and 17 denotes proximity to the downstream side of the pass line of the edge heater 16. The bar heater 18 arranged in this manner is a descaler arranged close to the upstream side of the pass line of the bonding apparatus 3.

尚、クロップシャー１５、エッジヒータ１６、バーヒータ１７及びデスケーラ１８の配置は、連続（熱間）圧延設備の状況等により適宜選択して配置されるものであり、配置位置や配置の有無等は図示例に限定されるものではない。   The arrangement of the crop shear 15, the edge heater 16, the bar heater 17 and the descaler 18 is appropriately selected and arranged according to the state of the continuous (hot) rolling equipment, etc. It is not limited to the examples shown.

そして、本実施例では、クロップシャー７のパスライン下流側に近接して後行シートバー６の先端部における曲がり（状態）を検出する第１曲がり計測器（曲がり検出装置）２０と先行シートバー９の後端部における曲がり（状態）を検出する第２曲がり計測器（曲がり検出装置）２１が配置される。この第１曲がり計測器２０と第２曲がり計測器２１は、例えばＣＣＤカメラであり、その画像信号が後述する制御装置３０に送られる。尚、後行シートバー６の先端部及び先行シートバー９の後端部における曲がりを検出するにあたっては、１台の曲がり計測器で兼用することも可能であることは言うまでもない。   In this embodiment, a first bending measuring device (a bending detection device) 20 for detecting a bending (state) at the leading end portion of the succeeding sheet bar 6 close to the downstream side of the pass line of the crop shear 7 and a preceding sheet bar. A second bend measuring instrument (bend detecting device) 21 for detecting a bend (state) at the rear end of 9 is arranged. The first bend measuring instrument 20 and the second bend measuring instrument 21 are, for example, CCD cameras, and their image signals are sent to a control device 30 described later. Needless to say, in detecting the bending at the leading end of the trailing sheet bar 6 and the trailing end of the preceding sheet bar 9, it is possible to use a single bending measuring instrument.

また、前記第１曲がり計測器２０のパスライン上流側に近接して（図示例ではクロップシャー７のパスライン上流側に位置して）サイドガイド装置としての第１及び第２縦ローラ対２２，２３が所定間隔離間して配置される。この第１及び第２縦ローラ対２２，２３は、後行シートバー６の先端部における曲がりを第１曲がり計測器２０で計測するために後行シートバー６のセンタリングを行うものである。   Further, in the vicinity of the upstream side of the pass line of the first bending measuring instrument 20 (located in the upstream side of the pass line of the crop shear 7 in the illustrated example), first and second longitudinal roller pairs 22 as side guide devices, 23 are arranged at a predetermined interval. The first and second vertical roller pairs 22 and 23 are used for centering the succeeding sheet bar 6 in order to measure the bending at the leading end portion of the succeeding sheet bar 6 by the first bend measuring instrument 20.

また、前記第２曲がり計測器２１のパスライン下流側に近接して即ち、接合装置３のパスライン上流側に位置して（図示例ではデスケーラ１８を挾んで）サイドガイド装置としての第３及び第４縦ローラ対２４，２５（第３縦ローラ対２４が請求項６の第２の縦ローラに相当し、第４縦ローラ対２５が請求項６の第１の縦ローラに相当する）が所定間隔離間して配置される。この第３及び第４縦ローラ対２４，２５は、先行シートバー９の後端部における曲がりを第２曲がり計測器２１で計測するために先行シートバー９のセンタリングを行い、接合時は後行シートバー６の先端部における曲がりを少なくするように移動可能になっているものである。   Further, the third and third side guide devices are located close to the downstream side of the pass line of the second bending measuring instrument 21, that is, on the upstream side of the pass line of the joining device 3 (with the descaler 18 in the illustrated example). The fourth vertical roller pair 24, 25 (the third vertical roller pair 24 corresponds to the second vertical roller of claim 6 and the fourth vertical roller pair 25 corresponds to the first vertical roller of claim 6). Arranged at a predetermined interval. The third and fourth vertical roller pairs 24 and 25 perform the centering of the preceding sheet bar 9 in order to measure the bending at the rear end portion of the preceding sheet bar 9 by the second bending measuring instrument 21, and perform the following at the time of joining. The sheet bar 6 can be moved so as to reduce the bending at the front end portion thereof.

また、前記接合装置３のパスライン下流側に位置して（図示例ではクロップ処理装置１２を挾んで）サイドガイド装置としての第５及び第６縦ローラ対２６，２７（第５縦ローラ対２６が請求項６の第１の縦ローラに相当し、第６縦ローラ対２７が請求項６の第２の縦ローラに相当する）が所定間隔離間して配置される。この第５及び第６縦ローラ対２６，２７は、接合時に先行シートバー９の後端部における曲がりを少なくするように移動可能になっているものである。   Further, the fifth and sixth vertical roller pairs 26 and 27 (fifth vertical roller pair 26) as side guide devices are positioned downstream of the joining device 3 (passing the crop processing device 12 in the illustrated example). Corresponds to the first vertical roller of claim 6, and the sixth vertical roller pair 27 corresponds to the second vertical roller of claim 6). The fifth and sixth vertical roller pairs 26 and 27 are movable so as to reduce bending at the rear end portion of the preceding sheet bar 9 at the time of joining.

前記第１〜第６縦ローラ対２２〜２７は、図３に示すように、左右一対の第１〜第６縦ローラ対駆動装置２２ａ，２２ｂ〜２７ａ，２７ｂによってパスラインと直交する方向即ち、シートバーの幅方向に移動可能になっている。そして、第４及び第５縦ローラ対駆動装置２５ａ，２５ｂ、２６ａ，２６ｂは、図中左右のものがそれぞれ単独動作可能になっており、その他の縦ローラ対駆動装置２２ａ，２２ｂ〜２４ａ，２４ｂ、２７ａ，２７ｂは図中左右のものが同期して閉方向或いは開方向に移動可能になっている。尚、これらの縦ローラ対駆動装置２２ａ，２２ｂ〜２４ａ，２４ｂ、２７ａ，２７ｂも第４及び第５縦ローラ対駆動装置２５ａ，２５ｂ、２６ａ，２６ｂと同様に、図中左右のものがそれぞれ単独動作可能に構成しても良いことは言うまでもない。   As shown in FIG. 3, the first to sixth vertical roller pairs 22 to 27 are arranged in a direction orthogonal to the pass line by a pair of left and right first to sixth vertical roller pairs 22a, 22b to 27a, 27b, that is, It can be moved in the width direction of the seat bar. The fourth and fifth vertical roller pair driving devices 25a, 25b, 26a, and 26b can operate independently on the left and right sides in the figure, and the other vertical roller pair driving devices 22a, 22b to 24a, 24b. 27a and 27b are movable in the closing direction or the opening direction in synchronization with the left and right ones in the figure. These vertical roller pair drive devices 22a, 22b to 24a, 24b, 27a, 27b are also independent of the left and right ones in the figure, as are the fourth and fifth vertical roller pair drive devices 25a, 25b, 26a, 26b. Needless to say, it may be configured to be operable.

前記左右一対の第１〜第６縦ローラ対駆動装置２２ａ，２２ｂ〜２７ａ，２７ｂは、例えば油圧シリンダであり、その伸縮作動が後述する制御装置３０により駆動制御される。   The pair of left and right first to sixth vertical rollers 22a, 22b to 27a, 27b are, for example, hydraulic cylinders, and their expansion and contraction operations are driven and controlled by a control device 30 described later.

また、図１及び図２中２８は、仕上ミル４の入側に配置されたサイドガイド装置としてのガイドプレート対であり、このガイドプレート対駆動装置２８ａ，２８ｂ（図４参照）も後述する制御装置３０により駆動制御される。   In FIG. 1 and FIG. 2, reference numeral 28 denotes a pair of guide plates as side guide devices disposed on the entry side of the finishing mill 4, and the guide plate pair drive devices 28a and 28b (see FIG. 4) are also described later. The drive is controlled by the device 30.

前記制御装置３０には、図４に示すように、第１及び第２曲がり計測器２０，２１から例えば画像信号が入力される。そして、これら画像信号等の入力信号に基づいて左右一対の第１〜第６縦ローラ対駆動装置２２ａ，２２ｂ〜２７ａ，２７ｂとガイドプレート対駆動装置２８ａ，２８ｂを駆動制御する。   As shown in FIG. 4, for example, an image signal is input to the control device 30 from the first and second bending measuring devices 20 and 21. Based on these input signals such as image signals, the left and right pair of first to sixth vertical roller pair driving devices 22a, 22b to 27a, 27b and the guide plate pair driving devices 28a, 28b are driven and controlled.

具体的には、接合に先立って、第１及び第２縦ローラ対駆動装置２２ａ，２２ｂ、２３ａ，２３ｂを駆動して第１及び第２縦ローラ対２２，２３で後行シートバー６の先端部をセンタリングした状態で、第１曲がり計測器２０で後行シートバー６における曲がり状態を検出・測定する。また、第３及び第４縦ローラ対駆動装置２４ａ，２４ｂ、２５ａ，２５ｂを駆動して第３及び第４縦ローラ対２４，２５で先行シートバー９の後端部をセンタリングした状態で、第２曲がり計測器２１で先行シートバー９の後端部における曲がり（状態）を検出・測定する。測定は、例えば両幅端位置を測定して、その両幅端位置からセンター位置を得る方式などがある。   Specifically, prior to joining, the first and second longitudinal roller pair driving devices 22a, 22b, 23a, and 23b are driven, and the leading end of the succeeding sheet bar 6 is driven by the first and second longitudinal roller pairs 22 and 23. With the part centered, the bending state of the trailing sheet bar 6 is detected and measured by the first bending measuring instrument 20. Further, the third and fourth vertical roller pair driving devices 24a, 24b, 25a, 25b are driven and the rear end portion of the preceding sheet bar 9 is centered by the third and fourth vertical roller pairs 24, 25. The bend (state) at the rear end portion of the preceding sheet bar 9 is detected and measured by the 2-bend measuring instrument 21. The measurement includes, for example, a method of measuring the both width end positions and obtaining the center position from the both width end positions.

即ち、第１及び第２曲がり計測器２０，２１から入力された例えば画像信号を画像処理して、後行シートバー６の先端部における曲がり（状態）と先行シートバー９の後端部における曲がり（状態）を検出・測定するのである。そして、その測定結果から接合位置における幅方向のセンター位置（パスライン方向に沿った一点鎖線参照）のずれ量δf ，δp を演算する（図５（ａ）参照）。 That is, for example, image signals input from the first and second bending measuring devices 20 and 21 are subjected to image processing, and the bending (state) at the leading end portion of the succeeding sheet bar 6 and the bending at the trailing end portion of the preceding sheet bar 9 are performed. (State) is detected and measured. Then, deviation amounts δ f and δ p of the center position in the width direction at the joining position (see the alternate long and short dash line along the pass line direction) are calculated from the measurement result (see FIG. 5A).

次に、前記幅方向センター位置のずれ量δf ，δp が少なくなるように調整するための第４及び第５縦ローラ対２５，２６の移動量を演算してから（第３及び第６縦ローラ対２４，２７はセンタリングした位置で固定）、その分だけ第４及び第５縦ローラ対駆動装置２５ａ，２５ｂ、２６ａ，２６ｂを相反方向（図５（ｂ）中の矢印参照）にストロークさせて後行シートバー６の先端部と先行シートバー９の後端部を幅方向にずらす。尚、この際、第４及び第５縦ローラ対２５，２６のいずれか一方のみを移動させて幅方向センター位置のずれ量δf ，δp が少なくなるように調整しても良いことは言うまでもない。 Next, after calculating the movement amounts of the fourth and fifth vertical roller pairs 25 and 26 for adjusting the shift amounts δ f and δ p of the width direction center position to be small (third and sixth). The vertical roller pair 24, 27 is fixed at the centered position), and accordingly, the fourth and fifth vertical roller pair driving devices 25a, 25b, 26a, 26b are stroked in opposite directions (see arrows in FIG. 5B). Thus, the leading end of the succeeding sheet bar 6 and the trailing end of the preceding sheet bar 9 are shifted in the width direction. In this case, it goes without saying that only one of the fourth and fifth vertical roller pairs 25 and 26 may be moved to adjust the width direction center position deviations δ f and δ p to be small. Yes.

この後、接合装置３の接合機１０により、先行シートバー９の後端部と後行シートバー６の先端部との重ね合せ部を挟んでその両側から押し込んで剪断しながら接合される。この際、図５（ｃ）に示すように、幅ずれ部（図７（ｃ）のイ，ロ参照）が無い状態で接合される。   Thereafter, the joining device 10 of the joining device 3 is joined while being pushed and sheared from both sides with the overlapping portion of the rear end portion of the preceding sheet bar 9 and the front end portion of the succeeding sheet bar 6 interposed therebetween. At this time, as shown in FIG. 5 (c), the joining is performed without a width shift portion (see (a) and (b) of FIG. 7 (c)).

また、制御装置３０は、図６に示すように、ガイドプレート対駆動装置２８ａ，２８ｂを駆動制御し、ガイドプレート対２８の間隔を適宜制御し、例えば図６（ａ）の間隔Ｌ2 に制御することで、接合されたシートバー１１の蛇行の抑制や曲がりの矯正を行うことができる。一方、図６（ｂ）の間隔Ｌ3 に制御することで、接合されたシートバー１１の蛇行の抑制を行うことができる。即ち、図８の間隔Ｌ1と図６の間隔Ｌ2 ，Ｌ3との間において、Ｌ1＞Ｌ2 ，Ｌ3とすることができるのである。これは、上述したように、接合部に幅ずれ状態が生じてないことで可能となる。 Further, as shown in FIG. 6, the control device 30 controls the drive of the guide plate pair drive devices 28a and 28b, and appropriately controls the distance between the guide plate pair 28, for example, the control is performed to the distance L 2 in FIG. By doing so, it is possible to suppress meandering of the joined sheet bar 11 and correct the bending. On the other hand, by controlling the distance L 3 in FIG. 6B, the meandering of the joined sheet bars 11 can be suppressed. That is, L 1 > L 2 and L 3 can be established between the interval L 1 in FIG. 8 and the intervals L 2 and L 3 in FIG. As described above, this is possible because there is no width shift state at the joint.

このようにして、本実施例では、連続（熱間）圧延設備において、後行シートバー６の先端部と先行シートバー９の後端部を、その重ね合せ部を挟んで両側から押し込んで剪断しながら接合する際に、後行シートバー６の先端部における曲がり（状態）と先行シートバー９の後端部における曲がり（状態）を検出・測定し、その測定結果から接合位置における幅方向のセンター位置のずれ量δf ，δp を演算すると共に該ずれ量δf ，δp が少なくなるように調整するための第４及び第５縦ローラ対２５，２６の移動量を演算し、その分だけ後行シートバー６の先端部と先行シートバー９の後端部を幅方向に相反的にずらすようにしたので、先，後行シートバー９，６の接合位置における幅ずれを可及的に低減できる。 In this way, in this embodiment, in the continuous (hot) rolling facility, the leading end portion of the succeeding sheet bar 6 and the trailing end portion of the preceding sheet bar 9 are pushed from both sides with the overlapping portion interposed therebetween and sheared. During joining, the bending (state) at the leading end of the succeeding seat bar 6 and the bending (state) at the trailing end of the preceding seat bar 9 are detected and measured, and the width direction at the joining position is detected from the measurement result. The shift amounts δ f and δ p of the center position are calculated, and the movement amounts of the fourth and fifth vertical roller pairs 25 and 26 for adjusting the shift amounts δ f and δ p to be reduced are calculated. Since the leading end portion of the succeeding seat bar 6 and the trailing end portion of the preceding seat bar 9 are shifted in the width direction in a reciprocal manner, the width shift at the joining position of the preceding and succeeding seat bars 9 and 6 is possible. Can be reduced.

尚、後行シートバー６の先端部と先行シートバー９の後端部を幅方向に相反的にずらす（曲げる）際は、ずらす量（曲げる量）はシートバーの弾性変形の範囲内とすることが好ましい。弾性変形の範囲を超える場合、幅方向に永久変形が残り、第４及び第５縦ローラ対２５，２６と接合位置との間の幅方向位置が刻々と変化してしまい、接合位置で所望の幅方向位置を確保することが難しくなるのである。   When the leading end of the succeeding seat bar 6 and the trailing end of the preceding seat bar 9 are shifted (bent) in the width direction, the shifting amount (bending amount) is within the range of elastic deformation of the seat bar. It is preferable. When the elastic deformation range is exceeded, permanent deformation remains in the width direction, and the position in the width direction between the fourth and fifth vertical roller pairs 25 and 26 and the joining position changes every moment, and a desired position is obtained at the joining position. It is difficult to secure the position in the width direction.

このように後行シートバー６の先端部或いは先行シートバー９の後端部に存在する曲がりに起因した接合時の幅ずれを可及的に小さくしたので、ガイドプレート対２８により曲がりを矯正することが可能となり、接合位置を含めて全長の曲がりを少なくしながら仕上圧延が可能となる。仕上ミル４の出側でのシートバー１１の通板においても曲がりがなくて良好となる。また、巻き取ったコイルの姿においても、接合部に大きな段差は存在しなくなるという効果が得られる。   As described above, since the width deviation at the time of joining due to the bending existing at the leading end portion of the succeeding seat bar 6 or the trailing end portion of the preceding seat bar 9 is made as small as possible, the bending is corrected by the guide plate pair 28. Thus, finish rolling is possible while reducing the bending of the entire length including the joining position. Even in the threading of the sheet bar 11 on the exit side of the finishing mill 4, there is no bending, which is good. In addition, even in the form of the coil that has been wound, there is an effect that there is no large step at the joint.

また、接合部が仕上ミル４を通過する際にも先行シートバー９の後端部と後行シートバー６の先端部の幅方向センター位置が略全長部（一般部）と同様の位置を通過できるようになり、圧延が安定するという利点もある。   Further, when the joint portion passes through the finishing mill 4, the center position in the width direction of the rear end portion of the preceding seat bar 9 and the front end portion of the succeeding seat bar 6 passes through the same position as the substantially full length portion (general portion). There is also an advantage that the rolling becomes stable.

また、センター位置のずれを小さくすることができれば、仕上ミル４の各圧延機入側にあるサイドガイド装置の設定においても、接合部における大きな段差がなくなることから、設定方法が容易になる。   Further, if the shift of the center position can be reduced, the setting method is facilitated because there is no large step at the joint even when setting the side guide device on the entrance side of each rolling mill of the finishing mill 4.

尚、このような幅揃え装置及び方法は、突合せて接合する方式の場合、切断機（クロップシャー）で接合前に先行シートバーの後端部或いは後行シートバーの先端部のカット状態を接合時に再現する必要があり、本装置及び方法のように、接合時に曲がり分を少なくするように動かすことは難易度が高い。重ね合せて接合するような、後行シートバーの先端面や先行シートバーの後端面を直接使用しない接合方法では、この調整が現実的な設備で実現でき有効な手段となる。また、接合方式が重ね合せて剪断過程において接合を完了する方式の場合、前述の接合前の切断機（クロップシャー）によるカットを必要としない場合がある。突合せでなければ、切断機（クロップシャー）でのカットの有無に関わらず、上述した曲がりを少なくすることができる。   In addition, in the case of such a method of joining by joining, such a width aligning apparatus and method joins the cut state of the trailing end of the preceding sheet bar or the leading end of the succeeding sheet bar before joining with a cutting machine (crop shear). Sometimes it is necessary to reproduce, and like the present apparatus and method, it is difficult to move so as to reduce the amount of bending at the time of joining. In a joining method that does not directly use the leading end surface of the succeeding sheet bar or the trailing end surface of the preceding sheet bar, such as superimposing and joining, this adjustment can be realized with realistic equipment and is an effective means. In addition, when the joining method is a method in which the joining is completed in the shearing process, cutting by a cutting machine (crop shear) before joining may not be necessary in some cases. If it is not butt | matching, the above-mentioned bending can be decreased irrespective of the presence or absence of the cut with a cutting machine (crop shear).
