Description

本発明は、熱間圧延で製造された金属帯コイルの側面の不揃いを矯正するための金属帯コイルの側面不揃い矯正装置に関するものである。   TECHNICAL FIELD The present invention relates to a metal band coil side irregularity correcting device for correcting a side band irregularity of a metal band coil manufactured by hot rolling.

例えば製鉄所の熱延工場で製造されたコイル（鋼帯コイル）は、図７に示すように、コイル巻取り工程でのコイル１の先端の非定常部において、テレスコープ形状の巻きズレ（コイル側面の不揃い）９が生じることがある。この巻きズレ９はコイル１をアップエンド（軸方向が縦向き）に設置した際、コイル１のエッジ部（鋼帯幅端部）が折れ込み、品質不良の原因となる。   For example, as shown in FIG. 7, a coil (steel strip coil) manufactured at a hot rolling factory of a steel mill has a telescope-shaped winding deviation (coil) at an unsteady portion at the tip of the coil 1 in the coil winding process. 9) may occur. When the coil 1 is installed in the up end (the axial direction is vertical), the winding deviation 9 is folded at the edge portion (steel strip width end portion) of the coil 1 and causes a quality defect.

これに対して、コイル巻取り装置の後面に、平滑円盤にてコイル側面に荷重を付加して巻きズレを矯正する矯正装置があるが、矯正装置の受け側の強度が十分でないことから、矯正荷重を制約され、機能が十分に発揮できないという問題があった。   On the other hand, there is a straightening device on the rear side of the coil winding device that corrects the winding deviation by applying a load to the coil side surface with a smooth disk, but the strength on the receiving side of the straightening device is not sufficient. There was a problem that the load was restricted and the function could not be fully exhibited.

また、薄肉材などでは、この矯正作業において折れ込みを発生させることもあり、比較的小さい力で矯正効果を発揮するニーズがあった。   In addition, a thin material or the like may cause a fold in the straightening operation, and there is a need to exert a straightening effect with a relatively small force.

こういった背景から、近年の熱延工場では、巻取り後のコイルの搬送をダウンエンド（軸方向が横向き）でハンドリングして、この問題に対処しているケースもあるが、ハンドリングの際に折れ込みを誘発する可能性があるため、根本的な解決には至っていない。   Against this background, in recent hot rolling mills, there are cases where handling of the coil after winding is handled at the down end (the axial direction is sideways) to deal with this problem. Since it may induce folding, it has not yet been fundamentally resolved.

この問題に対しては、特許文献１には、コイル尾端部の矯正方法として、コイルをダウンエンドに回転させながら矯正する方法が記載されているが、コイル先端（内巻き）側は矯正荷重が大きいことは変わらない。   For this problem, Patent Document 1 describes a method of correcting the coil tail end while rotating the coil to the down end, but the coil tip (inner winding) side has a correction load. The fact that is big is unchanged.

また、特許文献２には、コイル先端を検出し、それを掴んだ後、内側に巻き締めながら修正する方法が提案されているが、コイル巾方向調整工程、先端検出工程、矯正工程、搬送工程と工程が複雑すぎ、サイクルタイムが多く要するため、巻きズレが大きすぎるものを選択的に実施するのであれば可能であるが、大量発生、連続発生の際には適用が難しいと推定できる。また、対象のコイルがダウンエンドであることを前提としており、コイルがアップエンドの際には適用は難しいし、設備費が大きくなることが推定される。   Further, Patent Document 2 proposes a method of detecting a coil tip, grasping the coil, and then correcting the coil while tightening it inside. However, the coil width direction adjusting step, the tip detecting step, the correcting step, and the conveying step are proposed. Since the process is too complicated and a lot of cycle time is required, it is possible to selectively carry out a winding deviation that is too large, but it can be estimated that the application is difficult in the case of a large number of occurrences and continuous occurrences. In addition, it is assumed that the target coil is a down end, and it is difficult to apply when the coil is an up end, and it is estimated that the equipment cost increases.

本発明は、上記のような事情に鑑みてなされたものであり、金属帯コイル（例えば、鋼帯コイル）の側面の不揃いを適切に矯正することができる金属帯コイルの側面不揃い矯正装置を提供することを目的とするものである。   This invention is made | formed in view of the above situations, and provides the side irregularity correction apparatus of the metal band coil which can correct appropriately the irregularity of the side surface of a metal band coil (for example, steel strip coil). It is intended to do.

本発明者らは、上記課題を解決するために、前述したような、平滑円盤にて金属帯コイルの側面に荷重を付加して金属帯コイルの巻きズレ（金属帯コイルの側面不揃い）を矯正することを前提にして、その際に問題となる矯正荷重（金属帯コイル側面に付加する荷重）を低減する方法について鋭意検討を行った。   In order to solve the above-mentioned problems, the present inventors correct the winding deviation of the metal band coil (the unevenness of the side surface of the metal band coil) by applying a load to the side surface of the metal band coil with a smooth disk as described above. As a premise, we have intensively studied a method for reducing the correction load (the load applied to the side surface of the metal strip coil) that becomes a problem at that time.

その結果、本発明者らは、平滑円盤を金属帯コイルの外周方向（巻き締め方向）に自由に回転できるようにすることを着想した。すなわち、金属帯コイルの巻きズレの矯正には、巻きズレが発生している個所の金属帯間の摩擦力に打ち勝つだけの荷重を付加すれば矯正は可能であるが、金属帯表面の平滑度や温度、また材質によってはスプリングバックが大きい場合は金属帯同士の密着度が大きくなり、矯正に要する荷重は大きくなる。これに対し、平滑円盤を金属帯コイルの外周方向（巻き締め方向）に自由に回転できるようにしておけば、平滑円盤で金属帯コイルの側面に荷重をかける際に、金属帯コイルの内径端部が金属帯コイルの巻き締め方向に逃げるので、小さい荷重で矯正することが可能となる。   As a result, the present inventors have conceived that the smooth disk can be freely rotated in the outer peripheral direction (winding direction) of the metal strip coil. In other words, to correct the winding deviation of the metal band coil, it is possible to correct it by adding a load that can overcome the frictional force between the metal bands where the winding deviation has occurred. If the springback is large depending on the temperature, the material, and the material, the degree of adhesion between the metal bands increases, and the load required for correction increases. On the other hand, if the smooth disk can be freely rotated in the outer circumferential direction (winding direction) of the metal band coil, the inner diameter end of the metal band coil is applied when a load is applied to the side surface of the metal band coil with the smooth disk. Since the portion escapes in the winding direction of the metal band coil, it is possible to correct with a small load.

上記の着想に基づいて、本発明は以下の特徴を有している。   Based on the above idea, the present invention has the following features.

［１］金属帯コイルの側面の不揃いを矯正するための側面不揃い矯正装置であって、アップエンドに設置された金属帯コイルの側面に荷重を付加する平滑盤と、該平滑盤を金属帯コイルの巻き締め方向に自由に回転できるようにする回転機構とを備えていることを特徴とする金属帯コイルの側面不揃い矯正装置。   [1] A side surface unevenness correcting device for correcting side surface unevenness of a metal band coil, a smoothing machine for applying a load to the side surface of the metal band coil installed at the up-end, and the smoothing machine using the metal band coil A device for correcting unevenness of a side surface of a metal band coil, comprising: a rotation mechanism that allows free rotation in the winding direction of the metal band coil.

［２］さらに、前記平滑盤を金属帯コイルの巻き締め方向に強制的に回転させる回転手段を備えていることを特徴とする前記［１］に記載の金属帯コイルの側面不揃い矯正装置。   [2] The metal band coil side irregularity correcting device according to [1], further including a rotating unit that forcibly rotates the smoothing plate in a winding direction of the metal band coil.

［３］予め金属帯コイルの内径内面を強制冷却する冷却手段を備えていることを特徴とする前記［１］または［２］に記載の金属帯コイルの側面不揃い矯正装置。   [3] The metal band coil side irregularity correction device according to [1] or [2], further including a cooling unit that forcibly cools the inner surface of the inner diameter of the metal band coil in advance.

［４］前記冷却手段は、平滑盤に装着されて、金属帯コイルの内径内面に冷却水を噴射するノズルを備えていることを特徴とする前記［３］に記載の金属帯コイルの側面不揃い矯正装置。   [4] The metal band coil according to [3], wherein the cooling means includes a nozzle that is attached to a smoothing plate and injects cooling water onto the inner diameter inner surface of the metal band coil. Straightening device.

本発明においては、金属帯コイル（例えば、鋼帯コイル）の側面の不揃いを適切に矯正することができる。すなわち、平滑盤にて金属帯コイル側面に荷重を付加して金属帯コイルの巻きズレ（側面不揃い）を矯正するに際して、従来は設備能力起因で矯正できなかったものが、同等の力でより広範囲の金属帯コイルにまで矯正可能となる。また、荷重向上のための設備投資を抑制できるほか、矯正に耐えうる基礎などの増強を回避できるようになる。   In the present invention, unevenness of the side surface of a metal strip coil (for example, a steel strip coil) can be corrected appropriately. In other words, when applying a load to the side of the metal band coil with a smoothing plate to correct the winding deviation of the metal band coil (unevenness on the side), what was previously impossible to correct due to equipment capacity is more extensive with the same force. It becomes possible to correct even metal band coils. In addition, it is possible to suppress the capital investment for improving the load and to avoid the reinforcement of the foundation that can withstand the correction.

本発明の実施形態を図面に基づいて説明する。   Embodiments of the present invention will be described with reference to the drawings.

［実施形態１］
図１は本発明の実施形態１における鋼帯コイル側面不揃い矯正装置を示す立面図である。 [Embodiment 1]
FIG. 1 is an elevational view showing a steel strip coil side surface irregularity correcting device in Embodiment 1 of the present invention.

図１に示すように、この実施形態１における鋼帯コイル側面不揃い矯正装置１０は、鋼帯コイル１がアップエンドに設置される基盤１１と、基盤１１に立設された支柱１２と、支柱１２に支持された上部フレーム１３と、上部フレーム１３に装着された油圧シリンダ１４と、油圧シリンダ１４に連結部材１５を介して取り付けられた平滑円盤（下面が平滑になっている円盤）１６とを備えている。   As shown in FIG. 1, the steel strip coil side surface irregularity correction device 10 according to the first embodiment includes a base 11 on which the steel strip coil 1 is installed at the up end, a support 12 that is erected on the base 11, and a support 12. The upper frame 13 supported on the upper frame 13, the hydraulic cylinder 14 attached to the upper frame 13, and the smooth disk (disk whose bottom surface is smooth) 16 attached to the hydraulic cylinder 14 via the connecting member 15. ing.

これにより、この鋼帯コイル側面不揃い矯正装置１０は、アップエンドに設置された鋼帯コイル１の側面に対して、油圧シリンダ１４を駆動して平滑円盤１６によって荷重を付加することで、鋼帯コイル１の側面不揃いを矯正するようになっている。   Thereby, this steel strip coil side surface irregularity correction apparatus 10 drives the hydraulic cylinder 14 with respect to the side surface of the steel strip coil 1 installed in the up end, and applies a load with the smooth disk 16, thereby the steel strip. The uneven side surface of the coil 1 is corrected.

その上で、この実施形態１においては、油圧シリンダ１４に対して平滑円盤１６を鋼帯コイル１の巻き締め方向に自由に回転できるようにする回転機構２０を備えている。   In addition, in the first embodiment, a rotation mechanism 20 that allows the smooth disk 16 to freely rotate in the winding direction of the steel strip coil 1 with respect to the hydraulic cylinder 14 is provided.

その回転機構２０の詳細は、図２に断面図を示すように、油圧シリンダ１４と連結部材１５との間にアキシャル軸受２１とスラスト軸受２２を装着したものである。これによって、連結部材１５に固定された平滑円盤１６が油圧シリンダ１４に対して鋼帯コイル１の巻き締め方向に自由に回転できることになる。なお、スラスト軸受２２は油圧シリンダ１４からの矯正荷重を受け持つ。ここで、図２中の２４はオイルシールである。   The details of the rotating mechanism 20 are such that an axial bearing 21 and a thrust bearing 22 are mounted between the hydraulic cylinder 14 and the connecting member 15 as shown in a sectional view in FIG. Accordingly, the smooth disk 16 fixed to the connecting member 15 can freely rotate in the winding direction of the steel strip coil 1 with respect to the hydraulic cylinder 14. The thrust bearing 22 is responsible for the straightening load from the hydraulic cylinder 14. Here, 24 in FIG. 2 is an oil seal.

なお、上記に加えて、この実施形態１においては、図１に示すように、平滑円盤１６を鋼帯コイル１の巻き締め方向に強制的に回転させるための油圧シリンダ３１を備えている。ここで、図１中の３２は油圧シリンダ３１を油圧シリンダ１４に取り付けるための補助部材である。   In addition to the above, the first embodiment includes a hydraulic cylinder 31 for forcibly rotating the smooth disk 16 in the winding direction of the steel strip coil 1 as shown in FIG. Here, 32 in FIG. 1 is an auxiliary member for attaching the hydraulic cylinder 31 to the hydraulic cylinder 14.

上記のように構成された鋼帯コイル側面不揃い矯正装置１０を用いて鋼帯コイル１の側面不揃い（巻きズレ）を矯正する際の動作手順を図３に示す。すなわち、下記の（Ｓ１）〜（Ｓ３）の動作手順によって行う。   FIG. 3 shows an operation procedure for correcting the uneven side surface (winding deviation) of the steel strip coil 1 using the steel strip coil side surface unevenness correcting device 10 configured as described above. That is, it is performed by the following operation procedure (S1) to (S3).

（Ｓ１）まず、図３（ａ）に示すように、鋼帯コイル１を基盤１１上の所定の位置にアップエンドで設置する。そして、油圧シリンダ１４を駆動して、平滑円盤１６を下降させる。   (S1) First, as shown in FIG. 3A, the steel strip coil 1 is installed at a predetermined position on the base 11 in an up-end. Then, the hydraulic cylinder 14 is driven to lower the smooth disk 16.

（Ｓ２）図３（ｂ）に示すように、平滑円盤１６が鋼帯コイル１に接触したら、さらに平滑円盤１６を下降させて、平滑円盤１６によって鋼帯コイル１の側面に荷重を付加する。   (S2) As shown in FIG. 3B, when the smooth disk 16 comes into contact with the steel strip coil 1, the smooth disk 16 is further lowered and a load is applied to the side surface of the steel strip coil 1 by the smooth disk 16.

その際に、平滑円盤１６が回転機構２０によって鋼帯帯コイル１の巻き締め方向に自由に回転できるようになっているので、図３（ｃ）に示すように、鋼帯コイル１の内径端部２が鋼帯コイル１の巻き締め方向に逃げる。なお、必要に応じて、補助的に油圧シリンダ３１を駆動して、平滑円盤１６を金属帯コイル１の巻き締め方向に強制的に所定角度（例えば１０°）回転させるようにしてもよい。   At that time, since the smooth disk 16 can be freely rotated in the winding direction of the steel strip coil 1 by the rotation mechanism 20, as shown in FIG. The part 2 escapes in the winding direction of the steel strip coil 1. If necessary, the hydraulic cylinder 31 may be supplementarily driven to forcibly rotate the smooth disk 16 in the winding direction of the metal band coil 1 by a predetermined angle (for example, 10 °).

（Ｓ３）そして、その状態のもとで、図３（ｄ）に示すように、平滑円盤１６によって側面不揃い９を押込んで、矯正終了となる。   (S3) Then, under the state, as shown in FIG. 3 (d), the side surface unevenness 9 is pushed in by the smooth disk 16, and the correction ends.

このようにして、この実施形態１においては、アップエンドに設置された鋼帯コイル１の側面に平滑円盤１６で荷重を付加することによって側面不揃い９を矯正するに際して、平滑円盤１６が回転機構２０によって鋼帯コイル１の巻き締め方向に自由に回転できるようになっていることから、平滑円盤１６で鋼帯コイル１の側面に荷重をかける際に、鋼帯コイル１の内径端部２が鋼帯コイル１の巻き締め方向に逃げるので、小さい荷重で矯正することが可能となる。   In this way, in the first embodiment, when the uneven surface 9 is corrected by applying a load with the smooth disk 16 to the side surface of the steel strip coil 1 installed at the up end, the smooth disk 16 is rotated by the rotating mechanism 20. Therefore, when a load is applied to the side surface of the steel strip coil 1 with the smooth disk 16, the inner diameter end 2 of the steel strip coil 1 is made of steel. Since it escapes in the winding direction of the band coil 1, it becomes possible to correct with a small load.

さらに、油圧シリンダ３１によって平滑円盤１６を鋼帯コイル１の巻き締め方向に強制的に回転させることで、上記の効果を一層確実なものにしている。   Further, the above-mentioned effect is further ensured by forcibly rotating the smooth disk 16 in the winding direction of the steel strip coil 1 by the hydraulic cylinder 31.

［実施形態２］
本発明の実施形態２における鋼帯コイル側面不揃い矯正装置は、上記の実施形態１における鋼帯コイル側面不揃い矯正装置について、鋼帯コイルの内径内面を冷却する冷却装置を設置して、予め鋼帯コイルの内径内面を強制冷却できるようにしたものである。 [Embodiment 2]
The steel strip coil side surface irregularity correcting device according to Embodiment 2 of the present invention is a steel strip coil side surface unevenness correcting device according to Embodiment 1 described above, in which a cooling device for cooling the inner diameter inner surface of the steel strip coil is installed, and the steel strip in advance. The inner diameter inner surface of the coil can be forcibly cooled.

すなわち、図４に立面図を示すように、この実施形態２における鋼帯コイル側面不揃い矯正装置１０’は、図１に示した実施形態１における鋼帯コイル側面不揃い矯正装置１０について、鋼帯コイル１の内径内面３に冷却水を噴射するための冷却装置４０として、噴射ヘッダ４１と噴射ノズル４２と冷却水供給配管４３とが平滑円盤１６に装着されている。なお、噴射ヘッダ４１と噴射ノズル４２は、鋼帯コイル１の内径空間部４に収まるような大きさになっている。   That is, as shown in an elevation view in FIG. 4, the steel strip coil side surface irregularity correcting device 10 ′ in the second embodiment is the same as the steel strip coil side surface irregularity correcting device 10 in the first embodiment shown in FIG. 1. As a cooling device 40 for injecting cooling water onto the inner diameter inner surface 3 of the coil 1, an injection header 41, an injection nozzle 42 and a cooling water supply pipe 43 are mounted on the smooth disk 16. The injection header 41 and the injection nozzle 42 are sized so as to fit in the inner diameter space 4 of the steel strip coil 1.

その冷却装置４０の詳細は、図５に立面図、図６に平面図を示すように、平滑円盤１６の中心に円形の噴射ヘッダ４１が設置され、その噴射ヘッダ４１に噴射ノズル４２が放射状に配置されている。なお、図５、図６において、４４、４５は噴射ヘッダ４１を平滑円盤１６に装着するための補助部材である。   The details of the cooling device 40 are as shown in an elevation view in FIG. 5 and a plan view in FIG. 6. A circular injection header 41 is installed at the center of the smooth disk 16, and the injection nozzles 42 are arranged radially in the injection header 41. Is arranged. In FIGS. 5 and 6, 44 and 45 are auxiliary members for mounting the injection header 41 to the smooth disk 16.

これによって、予め鋼帯コイル１の内径内面３を冷却装置４０により強制冷却するようにすれば、通常３００℃以上である鋼帯コイル１の内径側が冷却され、熱収縮により金属帯間に隙間が生じ、密着度を緩和できるので、より一層小さい荷重で矯正することが可能となる。   Thus, if the inner diameter inner surface 3 of the steel strip coil 1 is forcibly cooled by the cooling device 40 in advance, the inner diameter side of the steel strip coil 1 that is normally 300 ° C. or higher is cooled, and a gap is formed between the metal strips due to thermal contraction. As a result, the degree of adhesion can be relaxed, and correction can be made with a smaller load.

なお、上記の実施形態１、２においては、平滑円盤を用いて鋼帯コイルの側面に荷重を付加しているが、本発明では平滑円盤に限られるものではなく、平滑多角形盤等の他の平滑盤であってもよい。   In Embodiments 1 and 2 described above, a load is applied to the side surface of the steel strip coil using a smooth disk. However, the present invention is not limited to a smooth disk, and may be a smooth polygon disk or the like. The smoothing plate may be used.
