Abstract

【解決手段】
圧延品を圧延する、特に生産ライン或いは鋳造圧延装置において熱間広幅圧延する方法では、圧延品が圧延スタンドの圧延隙間へ流入する前に、潤滑剤が直接に作業ロール表面上に或いは間接的に支持ロール表面上に作業ロールの表面への伝達により塗布されて、この場合に作業ロール表面への強く付着する潤滑膜が生じて、ロールと圧延品との間の中間層として圧延隙間内で摩擦の減少を導き、潤滑剤が圧延品の全長にわたり塗布され、それによって潤滑作用が圧延品の全長さにわたり作用している。【Task】
To provide a method of applying a lubricant to a work roll surface or a support roll surface, which can improve the rolling process, reduce the roll wear, and reduce the energy consumption of the production line.
[Solution]
In the method of rolling a rolled product, particularly hot wide rolling in a production line or a casting and rolling apparatus, the lubricant is directly on the work roll surface or indirectly before the rolled product flows into the rolling gap of the rolling stand. It is applied on the surface of the support roll by transmission to the surface of the work roll, and in this case, a lubricating film that adheres strongly to the surface of the work roll is generated, and friction is generated in the rolling gap as an intermediate layer between the roll and the rolled product. The lubricant is applied over the entire length of the rolled product, so that the lubricating action is applied over the entire length of the rolled product.
Description
この発明は、圧延品が圧延スタンドの圧延隙間に流入する前に、潤滑剤が作業ロールの表面上に直接に或いは作業ロールの表面への伝達による支持ロールの表面上に間接に塗布される、この際に強力に付着する潤滑膜が作業ロール表面に形成し、その潤滑膜が圧延隙間内でロールと圧延品の間の中間膜として摩擦の減少を生じる、圧延品を圧延する、特に生産ライン或いは鋳造圧延装置における熱間広幅圧延する方法に関する。 In this invention, before the rolled product flows into the rolling gap of the rolling stand, the lubricant is applied directly on the surface of the work roll or indirectly on the surface of the support roll by transmission to the surface of the work roll. At this time, a lubricant film that adheres strongly is formed on the surface of the work roll, and the lubricant film causes a reduction in friction as an intermediate film between the roll and the rolled product within the rolling gap. Or it is related with the method of hot wide rolling in a casting rolling apparatus.
熱間圧延の高荷重生産ラインにおける圧延隙間潤滑の使用は公知である。けれども、この際に、潤滑はストリップヘッドにて遅延されて挿入後に適切なスタンドに接続されて、ベルト端の通す前に僅かな時間に再び遮断される。この措置は潤滑作用に応じて不利に圧延処理を奏する。 The use of rolling clearance lubrication in hot rolling high load production lines is known. However, at this time, the lubrication is delayed at the strip head, connected to a suitable stand after insertion, and shut off again for a short time before passing through the belt end. This measure disadvantageously rolls depending on the lubrication action.
ドイツ特許第２１０５９７５号明細書（特許文献１）から、工作物が通過する熱間圧延機構スタンドへの自動油供給装置が公知である。この装置は圧延スタンドの油噴霧装置、噴霧装置への油を供給する手段、油供給手段の運転を開始して、その直後に工作物の前端が圧延スタンドを通して到達する手段と油供給手段の運転を終了して、その直面に工作物の後端が圧延スタンドを到達する手段を包含する。 German Patent No. 2105975 (Patent Document 1) discloses an automatic oil supply device for a hot rolling mechanism stand through which a workpiece passes. This device starts the operation of the oil spraying device of the rolling stand, the means for supplying oil to the spraying device, the oil supplying means, and the operation of the oil supplying means and the means that the front end of the workpiece reaches through the rolling stand immediately after that. And includes means for the rear end of the workpiece to reach the rolling stand in the face of it.
米国特許第６２６６９８５号明細書（特許文献２）には、熱間圧延では圧延すべき圧延品の縁と端が潤滑剤を作用される方法が記載されている。 US Pat. No. 6,266,985 (Patent Document 2) describes a method in which a lubricant is applied to edges and ends of a rolled product to be rolled in hot rolling.
ドイツ特許第２０２２９２３号明細書（特許文献３）から、熱間圧延機構内に工作物に潤滑剤を塗布する方法と装置が公知であり、この場合には二つの作業ロールと二つの支持ロールとを備える四つの圧延スタンドには潤滑剤と噴霧空気は複数の噴霧ノズルに引き渡される。噴霧ノズルは幅を横切ってこれら支持ロールの少なくとも一つが配置されている。工作物が作業ロールに流入するとすぐに、潤滑剤が支持ロールに塗布されて、そこから作業ロールにさらに与えられる。ノズルへの潤滑剤流れと噴霧空気流れとは、工作物が作業ロールを去るとすぐに、遮断される。 German Patent No. 2022923 (Patent Document 3) discloses a method and apparatus for applying a lubricant to a workpiece in a hot rolling mechanism, in this case two work rolls and two support rolls. The four rolling stands having the lubricant and the spray air are delivered to a plurality of spray nozzles. At least one of these support rolls is arranged across the width of the spray nozzle. As soon as the workpiece flows into the work roll, lubricant is applied to the support roll and from there it is further applied to the work roll. The lubricant flow to the nozzle and the atomizing air flow are interrupted as soon as the workpiece leaves the work roll.
潤滑剤搬出の開始時点は観察されたスタンド内の挿入である。この方法或いはこの装置において、まず最初に閉鎖された潤滑剤膜が支持ロール表面上に形成されなればならなく、支持ロール／作業ロールの隙間に作業ロール表面上に塗布されることが欠点である。この作業ロール表面から潤滑剤は圧延隙間に到達する。潤滑剤が圧延品へ到達するまで、圧延周辺速度と圧延直径に応じて多過ぎる時間（複数秒）が経過する。この種の方法或いはこの種の装置では、ストリップ端が通過する際に新鮮な潤滑剤を供給されておらず、それで短時間により高い圧延力を生じる。 The starting point for lubricant delivery is the observed insertion in the stand. In this method or in this apparatus, the closed lubricant film must first be formed on the surface of the support roll, and is disadvantageously applied to the surface of the work roll in the gap between the support roll / work roll. . The lubricant reaches the rolling gap from the surface of the work roll. Too much time (multiple seconds) passes depending on the rolling peripheral speed and the rolling diameter until the lubricant reaches the rolled product. In this type of process or in this type of apparatus, no fresh lubricant is supplied as the strip ends pass, so that a higher rolling force is produced in a shorter time.
基本的には隙間内で摩擦なしの圧延は不可能である、というのは、十分な摩擦の際にのみ圧延品が得られて、圧延隙間を通して引き出される。いつも、所謂噛込みや通過要件が満たされることが確保されなればならない。最小に必要な摩擦に関連して、噛込み要件が−これは圧延品の発端における関係を記載する−通過要件より実質的に臨界的である。通過要件では、圧延隙間は完全に圧延品により満たされる。両要件の一方、或いは両要件が満たされないならば、シュート（Rutschen) 、つまりすべりをロールと圧延品の間に生じる。 Basically, rolling without friction in the gap is impossible, because a rolled product is obtained only when there is sufficient friction and is drawn through the rolling gap. It must always be ensured that so-called biting and passage requirements are met. In relation to the minimum required friction, the biting requirement—which describes the relationship at the beginning of the rolled product—is substantially more critical than the passage requirement. With the passage requirements, the rolling gap is completely filled with the rolled product. If one or both of the requirements are not met, a Rutschen, or slip, occurs between the roll and the rolled product.
摩擦自体を記載する摩擦係数に追加して、噛込み角度と圧延速度は一つの役割を果たす。圧延速度の増加により噛込み能力が減少する。循環する圧延品の厚さに依存する噛込み角度のために、ロールとロールの直径における相対厚さ減少は、すべりのない圧延を可能とするために噛込み角度がいつも摩擦角度より小さいことを要する。減少分布では、生産ラインにおける噛込み角度は第一スタンドから最終スタンドまで減少する。その後に最大噛込み問題は第一仕上げスタンドで圧延品の発端にシュートを生じる。 In addition to the friction coefficient describing the friction itself, the biting angle and rolling speed play a role. The biting ability decreases with increasing rolling speed. Due to the biting angle depending on the thickness of the rolled product, the relative reduction in thickness between rolls and roll diameters means that the biting angle is always smaller than the friction angle in order to allow rolling without slippage. Cost. In the decreasing distribution, the biting angle in the production line decreases from the first stand to the final stand. Thereafter, the maximum biting problem causes a chute at the beginning of the rolled product at the first finishing stand.
圧延品の発端における噛込み要件が圧延品の通過要件より満たすのがより難しいから、圧延隙間潤滑は、各スタンド内の挿入後に初めて潤滑が接続され、圧延品の通し前の僅かな時間が切り換えらるように設置される。この形式では、圧延表面上にある潤滑剤を完全に燃焼させるために十分な作業ロール押し寄せが残っている。それ故に、後続圧延品の発端における噛込みが危険にさらされることが回避される。 Since the biting requirements at the beginning of the rolled product are more difficult to meet than the requirements for passing the rolled product, the rolling gap lubrication is connected for the first time after insertion in each stand, and the slight time before passing the rolled product is switched. It is installed so that In this form, sufficient work roll thrust remains to completely burn the lubricant on the rolling surface. Therefore, it is avoided that the biting at the beginning of the subsequent rolled product is jeopardized.
記載された潤滑対策によって圧延品の内部に二つの異なる荷重水準が生じ、この場合に予備ストリップ或いは薄いスラブが均質特性により長さにわたり且つ速度アップなしで生産ラインに到着することが仮定される。
圧延品の発端と終端における高荷重水準（潤滑作用なしに）と圧延品の通常領域における低い圧延力水準（潤滑作用）
The described lubrication measures result in two different load levels inside the rolled product, in which case it is assumed that the pre-strip or thin slab arrives at the production line over the length and without speeding up due to the homogeneous properties.
High load level at the beginning and end of the rolled product (without lubrication) and low rolling force level in the normal region of the rolled product (lubricating)
５０％までとそれ以上に寄与できる作用潤滑における圧延力の減少によって作業ロールのたわみは変化する。それ故に、同時に計画状態（後スタンドにて標準的に）と圧延品の形状（前スタンドにて標準的に）が変化する。 The deflection of the work roll changes with a reduction in rolling force in working lubrication that can contribute up to 50% and beyond. Therefore, the planned state (standard in the rear stand) and the shape of the rolled product (standard in the front stand) change at the same time.
作業ロール曲げが各スタンド内の調整部材として自由になるならば、大きな圧延力減少では調整限度がしばしば達成される。その結果は特に薄ストリップ圧延において圧延品の不安定な走行となる。 If work roll bending is free as an adjustment member within each stand, adjustment limits are often achieved with large reductions in rolling force. The result is unstable running of the rolled product, especially in thin strip rolling.
圧延力減少をおよそ２０％の値に限定することが普通である。
この発明の課題は、圧延処理の改良を可能とし、ロールの摩耗に関する減少をまねき且つ生産ラインのエネルギー消費を下げる、作業ロール表面或いは支持ロール表面に潤滑剤を塗布する方法を提供することである。 An object of the present invention is to provide a method for applying a lubricant to a work roll surface or a support roll surface, which can improve the rolling process, reduce the roll wear, and reduce the energy consumption of the production line. .
この課題は、この発明によると、請求項１の特徴とする特徴事項によって解決される。この発明の好ましい構成は従属請求項に挙げられている。 According to the present invention, this problem is solved by the characteristic features of claim 1. Preferred configurations of the invention are listed in the dependent claims.
潤滑剤を貯蔵容器から導管とノズルを介して作業ロール或いは支持ロールまで搬送する潤滑システムが圧延スタンドへの圧延品の流入前既に５秒から１５秒まで接続されるならば、潤滑システムにおけるすべての無駄時間が補償されるので、各場合に既に挿入前に閉鎖された潤滑膜が作業ロール上で形成されている。 If the lubrication system that transports the lubricant from the storage container through the conduit and nozzle to the work roll or support roll is already connected for 5 to 15 seconds before the rolling product enters the rolling stand, all lubrication systems in the lubrication system Since the dead time is compensated, in each case, a lubricating film which has already been closed before insertion is formed on the work roll.
この発明の方法の適切な利点は、潤滑が圧延品の全長にわたり維持されるから、圧延品の全長にわたり各スタンドの一定圧延力水準が与えられることにある。 A suitable advantage of the method of the invention is that since the lubrication is maintained over the entire length of the rolled product, a constant rolling force level for each stand is provided over the entire length of the rolled product.
圧延定数に基づいて、例えば４０％から５０％までの全体でより高い圧延力減少が達成され、それによって圧延ラインの荷重が摩耗とエネルギー消費を考慮して明確に減少される。さらに、より高い圧延力減少によって作業ロール摩耗が減少され、それにより圧延使用時間（耐用年数）が延長される。 Based on the rolling constant, a higher rolling force reduction is achieved, for example from 40% to 50% overall, whereby the load on the rolling line is clearly reduced taking into account wear and energy consumption. Furthermore, higher roll force reduction reduces work roll wear, thereby extending the rolling service time (service life).
それ故に、この発明による方法の利点は：
・一定圧延力減少；
・計画状態の圧延力と関連する変更なし；
・ベルト形状の圧延力と関連する変更なし；
・圧延品の発端と終端における力が明らかに減少されるので、スタンド振動と圧延損傷が有効に回避され得る；
・それから減少再分配のかなりの遊び空間が生じ、それにより臨界的製品の圧延における最適挿入計画が生じる；
・圧延品の終端における計画状態が圧延力に基づいて変更するので、圧延品の発端の圧延が回避され得る。
The advantages of the method according to the invention are therefore:
・ Constant rolling force reduction;
-No change related to planned rolling force;
・ No changes related to the rolling force of the belt shape;
-Stand vibration and rolling damage can be effectively avoided since the forces at the beginning and end of the rolled product are clearly reduced;
It then creates a considerable play space for reduced redistribution, which results in an optimal insertion plan in the rolling of critical products;
Since the planned state at the end of the rolled product is changed based on the rolling force, rolling at the beginning of the rolled product can be avoided.
この発明による潤滑の使用の仮定は、圧延品の発端における噛込み要件が確保されていることである。 The assumption of the use of lubrication according to the invention is that the biting requirements at the beginning of the rolled product are ensured.
生産ライン或いは鋳造圧延装置における潤滑剤のこの発明による塗布は、好ましくは第二スタンドから且つあらゆる後続スタンドのために制限なしに可能である。 Application of the lubricant according to the invention in the production line or in the casting and rolling apparatus is preferably possible without limitation from the second stand and for any subsequent stand.
第一仕上げスタンドでは、（より高い噛込み角度）圧延品の大きな厚さに基づいて一般に潤滑剤が塗布されていない。潤滑剤をこの発明により既に第二仕上げスタンドに塗布するために、各装置の現在の関係が考慮される。このために例えば、
・研磨後の圧延表面の状態，
・作業ロール直径，
・作業ロール材料，
・走行ベルト厚さ，
・調整された相対減少，
・走行圧延品の表面状態（スケール、温度、粗度、材料など），
・挿入された潤滑剤，
・潤滑剤量，
・圧延速度。
In the first finishing stand, the lubricant is generally not applied based on the large thickness of the rolled product (higher bite angle). In order to apply the lubricant to the second finishing stand according to the present invention, the current relationship of each device is taken into account. For this, for example,
・ The state of the rolled surface after polishing,
・ Work roll diameter,
・ Work roll materials,
・ Running belt thickness,
-Adjusted relative reduction,
・ Surface condition (scale, temperature, roughness, material, etc.)
.Inserted lubricant,
・ Lubricant amount,
・ Rolling speed.
噛込み角度が臨界的領域にあるならば、圧延品の発端において潤滑作用は潤滑剤の僅かな量によって或いは修正された、即ち他の特性を有する潤滑剤によって上方へ限定されている。 If the biting angle is in the critical region, the lubrication action at the beginning of the rolled product is limited upward by a small amount of lubricant or modified, i.e. by a lubricant having other properties.
潤滑剤を圧延表面上に塗布するこの発明による方法の使用では、この運転用の生産ラインの挿入計画モデルを準備することが推薦されている。この場合に、適応された運転を圧延隙間潤滑なしに影響を与えないために、適応マトリックスの少なくとも一つの裏打ちが企図されている。物理的モデルでは、摩擦係数の異なるセットの基準値は−潤滑された状態と潤滑されていない状態のために−操業開始のために並びに新たな製品の採用の際及びより高い適応値を回避するために、大きな利点である。 In the use of the method according to the invention for applying a lubricant on the rolling surface, it is recommended to prepare an insertion planning model for the production line for this operation. In this case, at least one backing of the adaptation matrix is contemplated in order not to affect the adapted operation without rolling gap lubrication. In the physical model, the reference values for different sets of coefficient of friction are-for lubricated and unlubricated conditions-for start-up and when adopting new products and avoiding higher adaptation values Because it is a great advantage.
各摩擦変更は前進の変更と、即ち質量流変更或いは質量流障害と結びついている。この種の障害は制御システムから制御されなければならない、それは臨界的薄ストリップ圧延において著しい困難を導き得る。 Each friction change is associated with a forward change, ie, a mass flow change or mass flow disturbance. This kind of obstacle must be controlled from the control system, which can lead to significant difficulties in critical thin strip rolling.
この発明による方法の別の利点は、一定潤滑の際には一定の前進が達成され、それはさらに一定の質量流という結果を生じる。 Another advantage of the method according to the invention is that a constant advance is achieved during constant lubrication, which also results in a constant mass flow.
フェライト圧延の際に圧延隙間潤滑は表面における剪断組織に有効に影響させるために使用される。潤滑剤のこの発明の塗布は全圧延長さにわたり均一な表面組織を生じる。 Rolling gap lubrication is used to effectively affect the shear structure at the surface during ferrite rolling. Application of the lubricant of this invention results in a uniform surface texture over the entire rolling length.
潤滑システムでは、潤滑の開始の際に遅延時間を回避するために潤滑剤タンクへの帰還部を備える環状導管の構成や切換え可能な３／２路の取付け−潤滑剤用の混合機前の弁が設けられている。 In lubrication systems, the configuration of an annular conduit with a return to the lubricant tank and a switchable 3 / 2-way installation to avoid a delay time at the start of lubrication-a valve before the mixer for the lubricant Is provided.
