この考案は、冷延鋼板あるいはめっき鋼板等の鋼帯表面に化成処理を施したの ち、鋼帯に付着した処理液をリンガーロールで絞って所定の膜厚にするに際し、 鋼帯の両端面部に残存する処理液による鋼帯端面部およびエッジの着色を防止す る装置に関する。 This idea is based on chemical conversion treatment applied to the surface of steel strips such as cold-rolled steel sheets or plated steel sheets. First, when squeezing the treatment liquid adhering to the steel strip with a ringer roll to achieve a predetermined film thickness, To prevent coloring of the steel strip ends and edges due to treatment liquid remaining on both ends of the steel strip. related to the equipment used.
【０００２】0002
冷延鋼板に代表される薄板は、自動車用、家電製品用として、あるいはめっき 原板として今日広く用いられている。冷延鋼板は錆やすいため、めっきされるか 、化成処理後塗装して使用されている。塗装鋼板等の用途に用いられる表面処理 鋼板は、近年製品の高級化に伴って拡大増加の傾向にあり、その前処理としての 化成処理量も増大し、その製造ラインもこれに対応すべく高速化が図られている 。 Thin sheets, typically cold-rolled steel sheets, are used for automobiles, home appliances, or plated. It is widely used today as a base plate. Cold-rolled steel sheets are susceptible to rust, so are they plated? It is used after being painted after chemical conversion treatment. Surface treatment used for painted steel plates, etc. The use of steel sheets has been on the rise in recent years as products have become more sophisticated, and as a pre-treatment process, The amount of chemical conversion processing is also increasing, and the production lines are also becoming faster to accommodate this increase. .
【０００３】 上記表面処理鋼板の製造ラインにおいて、高速で連続送給される鋼帯は、浸漬 法、スプレー法あるいはスプレー法＋浸漬法により化成処理されたのち、リンガ ーロールによって処理液が絞り取られ、所定の膜厚に調整される。この膜厚調整 工程において、リンガーロールの両端部には、鋼帯の板厚に応じてロール間隙が 生じる。このため、リンガーロールによって絞り取られた処理液は、リンガーロ ールのメニスカス部を経由してこの部分よりリンガーロール出側に排出されるこ ととなる。0003 In the production line for the above-mentioned surface-treated steel sheets, the steel strips that are continuously fed at high speed are immersed. After being chemically treated by the method, spray method, or spray method + dipping method, the ringer - The processing liquid is squeezed out by the rolls and adjusted to a predetermined film thickness. This film thickness adjustment In the process, there is a gap between the rolls at both ends of the ringer roll depending on the thickness of the steel strip. arise. Therefore, the processing liquid squeezed out by the Ringer roll is This part passes through the meniscus part of the roll and is discharged from this part to the exit side of the ringer roll. It becomes.
【０００４】 このため、図３に示すとおり、鋼帯２１の端面部２２およびエッジ部２３には 、リンガーロール２４の圧下により鋼帯２１の中央部２５に比較して処理液が多 く残留する、いわゆるオーバーコートが発生し、鋼帯端面部２２の着色あるいは エッジ部２３の膜厚過大による処理ムラが生じていた。特に鋼帯端面部２２につ いては、圧倒的に生産量の多い圧延したままのミルエッジを有する場合に、この 凹みの部分に残存処理液が蓄積されるため、着色の程度が著しく、見栄え等の製 品用途上問題を有していた。0004 Therefore, as shown in FIG. 3, the end surface portion 22 and edge portion 23 of the steel strip 21 , due to the rolling down of the ringer roll 24, the amount of processing liquid is larger than that in the central part 25 of the steel strip 21. A so-called overcoat that remains on the steel strip ends up discoloring the end surface 22 of the steel strip. Processing unevenness occurred due to the excessive film thickness of the edge portion 23. Especially regarding the steel strip end face 22. This method is used in cases where the mill edge is as rolled, which is by far the largest production volume. As the residual processing liquid accumulates in the dented area, the degree of coloring is significant and the appearance etc. There were problems with product usage.
【０００５】 上記化成処理された鋼板端面部の着色およびエッジ部膜厚過大による処理ムラ を防止する方法としては、例えば、端面部の着色の場合には、サイドトリマー等 により端面トリムを行ったのち、化成処理を施せば軽減されるが、その半面製造 工程の増加、トリム工具の使用等による製造コストの上昇が避けられないという 欠点を有しており、好ましい方法ではない。[0005] Uneven treatment due to discoloration of the chemically treated steel plate end face and excessive film thickness at the edge. For example, when coloring the end surface, use a side trimmer, etc. to prevent this. This can be alleviated by performing chemical conversion treatment after trimming the end surface, but on the other hand, manufacturing It is said that an increase in manufacturing costs due to increased steps and the use of trim tools is unavoidable. It has drawbacks and is not a preferred method.
【０００６】 また、エッジ部処理ムラについては、鋼帯エッジ部あるいは全幅面にエアーノ ズルを用いて鋼帯の厚み方向両側からエアーを吹付け、残存処理液を除去する方 法（特公昭５３−２３８５７号公報、特開昭６０−２０８４８２号公報、実開昭 ６２−１９８２７０号公報、実開平２−１０６４６２号公報、実開平２−１０６ ４６３号公報）が提案されている。[0006] In addition, regarding uneven edge treatment, air injection molding is performed on the edge of the steel strip or on the entire width surface. A method in which residual treatment liquid is removed by blowing air from both sides of the steel strip in the thickness direction using a screw. Act (Japanese Patent Publication No. 53-23857, Japanese Unexamined Patent Application Publication No. 60-208482, Japanese Unexamined Patent Publication No. 60-208482, No. 62-198270, Japanese Utility Model Application No. 2-106462, Japanese Utility Model Application No. 2-106 No. 463) has been proposed.

上記特公昭５３−２３８５７号公報、特開昭６０−２０８４８２号公報、実開 昭６２−１９８２７０号公報の方法は、鋼帯エッジ部の処理ムラを軽減できるも のの、鋼帯端面部のミルエッジの凹部に残存する処理液の除去が困難で、端面部 の着色を防止できない。しかも、エアーの吹付け方法によっては、エアー吹付け の際スプラッシュが膜厚調整を行った鋼帯中央部に飛散して再付着し、品質を低 下させるという欠点を有している。 The above-mentioned Japanese Patent Publication No. 53-23857, Japanese Patent Application Publication No. 60-208482, Utility Model Application No. The method disclosed in Japanese Patent Publication No. 198270/1983 can reduce the unevenness of treatment at the edge of the steel strip. Nono, it is difficult to remove the treatment liquid remaining in the recesses of the mill edge at the end of the steel strip, and the end cannot prevent coloring. Moreover, depending on the air blowing method, air blowing During this process, the splash scatters and re-attaches to the center of the steel strip where the film thickness has been adjusted, reducing quality. It has the disadvantage of being lowered.
【０００８】 また、実開平２−１０６４６２号公報、実開平２−１０６４６３号公報に開示 の装置は、前記エアー吹付けの際スプラッシュの飛散防止用のエアーカーテンを 備えており、膜厚調整を行った鋼帯中央部へのスプラッシュの飛散を防止できる が、鋼帯端面部のミルエッジの凹部に残存する処理液の除去が困難で、端面部の 着色を十分に防止することができない。[0008] Also disclosed in Utility Model Application Publication No. 2-106462 and Utility Model Application Publication No. 2-106463. This device uses an air curtain to prevent the splash from scattering during the air blowing process. This feature prevents splashes from scattering to the center of the steel strip where the film thickness has been adjusted. However, it is difficult to remove the treatment liquid remaining in the recesses of the mill edge at the end of the steel strip, and It is not possible to sufficiently prevent coloring.
【０００９】 この考案の目的は、上記化成処理鋼帯の端面部およびエッジ部の双方への処理 液の過剰残存を抑制し、端面部の着色とエッジ部の処理ムラを防止できる化成処 理鋼帯の端面およびエッジの着色防止装置を提供することにある。[0009] The purpose of this invention is to treat both the end face and edge of the chemically treated steel strip. A chemical conversion treatment that suppresses excessive residual liquid and prevents coloring of end faces and uneven treatment of edges. An object of the present invention is to provide a device for preventing discoloration of the end face and edge of a steel strip.

本考案者らは、上記目的を達成すべく鋭意検討を行った。その結果、化成処理 鋼帯の端面着色の発生は、リンガーロール圧下の際の鋼帯両端部における処理液 排出によるもので、鋼帯エッジ部と接触する部分のリンガロールが処理液により 濡れ、これによって端面が着色することに着目し、リンガーロールによる圧下に 際し、鋼帯の板厚と同等もしくは近似した厚みのベルト構造物、またはリンガー ロールによる圧下によって、鋼帯の板厚と同等の厚みまで圧縮される弾性体より なるベルトを、鋼帯両端部に接続して鋼帯幅を模擬的に拡大させることにより、 鋼帯の端面およびエッジ部に発生していた着色や処理ムラが該ベルトの端部で発 生することを究明し、この考案に到達した。 The inventors of the present invention conducted extensive studies to achieve the above object. As a result, chemical treatment The occurrence of coloring on the edge of the steel strip is caused by the treatment liquid at both ends of the steel strip during ringer roll rolling. This is due to discharge, and the ringer roll in contact with the edge of the steel strip is affected by the treatment liquid. We focused on the fact that the end surface becomes colored due to wetness, and applied pressure by a ringer roll. In this case, a belt structure with a thickness similar to or similar to that of the steel strip, or a ringer From an elastic body that is compressed to the same thickness as the steel strip by rolling down with rolls. By connecting a belt to both ends of the steel strip to simulate the width of the steel strip, Coloring and uneven treatment that had occurred on the end face and edges of the steel strip have now occurred at the end of the belt. We researched how to make this happen and came up with this idea.

When adjusting the end face of the steel strip and the edge coloring prevention device, the steel strip is placed on both sides of the steel strip. Carts facing each other with the band in between are provided so as to be movable in the width direction of the steel band, and installed at the four corners of the carts. The steel strip is rolled to a thickness equivalent to that of the steel strip by rolling with a ringer roll. An endless belt made of an elastic material that can be compressed is rotatably wrapped around the steel strip, and both ends of the steel strip are attached together with the steel strip. The endless belt that is brought into contact with the roller is rolled down by a ringer roll.

An endless belt made of an elastic material that is compressed to the same thickness as the belt plate is brought into contact with the Because the steel strip is rolled down by roller rolls, the width of the steel strip is reduced to an endless belt structure or an endless belt. The coloring area that previously appeared on the end face and edge of the steel strip is moves to the end face and edge of the endless belt structure or the endless belt, and the steel strip Coloring on the end faces and edges is prevented.
【００１４】 なお、上記無端ベルト構造物または無端ベルトは、台車四隅のローラーによっ てリンガーロールの回転速度に応じて移動するが、必要であればラインスピード に応じて駆動させることもできる。また、鋼帯幅の変動に対する調整は、駆動モ ーターによりボールスクリューネジを回転させ、台車をガイドレールにそって移 動させることにより行う。さらに鋼帯の蛇行に対しては、蛇行量に対応して個々 に台車の移動量の調整を行えばよい。[0014] The above endless belt structure or endless belt is operated by rollers at the four corners of the cart. and move according to the rotational speed of the ringer roll, but if necessary change the line speed.
