The invention relates to a method for continuously producing a metal, in particular a cold-rolled strip (1), in particular a special steel strip, in which the strip to be finished (1) is in the conveying direction (R). It relates to a method and a device guided by (2) in which the strip (1) is subjected to rolling, heating and chemical treatment. In order to improve the productivity of this method, it is contemplated by the present invention that the rolling process is only carried out after heating the strip and after chemical treatment.
Description
この発明は、金属、特に冷間ストリップ、特に特殊鋼ストリップを連続的に製造する方法であって、仕上げるべきストリップが搬送方向において装置によって案内され、その装置内でストリップが圧延処理、加熱及び化学的処理を受ける連続的製造方法に関する。さらに、この発明は、特にこの方法を実施する装置に関する。 The invention relates to a method for continuously producing metals, in particular cold strips, in particular special steel strips, in which the strip to be finished is guided by a device in the conveying direction, in which the strip is rolled, heated and chemically treated. The present invention relates to a continuous manufacturing method that undergoes general processing. Furthermore, the invention relates in particular to an apparatus for carrying out this method.
冷間ストリップ、特に特殊鋼ストリップの製造の場合には、金属ストリップは種々の処理がストリップに行われる仕上げ装置を通過する。その場合にストリップは圧延処理にてストリップの厚さを減少される。さらに加熱処理が接続でき、その加熱処理によりストリップに特殊材料特性が失われる。さらに、ストリップが酸洗ラインを通過し、そのラインにて化学的処理によってスケールが除去されるから、ストリップはスケールのない表面を有するにちがいない。 In the case of the production of cold strips, in particular special steel strips, the metal strip passes through a finishing device in which various treatments are performed on the strip. In that case, the strip is reduced in thickness by a rolling process. In addition, a heat treatment can be connected and the special material properties are lost in the strip due to the heat treatment. In addition, the strip must have an unscaled surface, as the strip passes through the pickling line where the scale is removed by chemical treatment.
更なる加工のために、例えば冷間加工によって金属被覆或いは最終製品への直接的加工のために、熱間圧延された鋼ストリップはスケールのない表面を有するにちがいない。それ故に、熱間圧延の際に且つ次の冷却中に生じるスケールは残留することなしに除去されるにちがいない。これは少なくとも一つの酸洗処理によって行われ、この場合に種々の酸化鉄(FeO,Fe3 O4 ,Fe2 O3 )から或いは耐腐食性鋼ではクロムの豊かな酸化鉄から成るスケールは種々の酸(例えば、塩酸、硫酸、硝酸或いは混合酸)による鋼品質に応じて上昇した温度にて酸との化学反応によって引き離される。酸洗前に普通鋼では大抵は延伸曲げ方向による追加の機械的処理は、スケールを破壊してそれでスケール層への酸の迅速侵入を可能とするために、必要である。本質的に酸洗するのがより難しい耐腐食性鋼、オーステナイト鋼やフェライト鋼の場合には、ストリップの焼き鈍しと機械的な予めのスケール除去は、出来るだけ良好な酸洗可能なストリップ表面を達成するために、酸洗処理において直列接続されている。 For further processing, for example by metal working by cold working or direct processing into the final product, the hot-rolled steel strip must have a scale-free surface. Therefore, the scale that occurs during hot rolling and during subsequent cooling must be removed without remaining. This is done by at least one pickling process, in which various scales of various iron oxides (FeO, Fe 3 O 4 , Fe 2 O 3 ) or in corrosion-resistant steel are composed of chromium-rich iron oxides. It is separated by a chemical reaction with an acid at an elevated temperature depending on the quality of the steel (eg hydrochloric acid, sulfuric acid, nitric acid or mixed acid). Prior to pickling, an additional mechanical treatment, usually in the direction of the stretch bend, is necessary in plain steel to break the scale and thus allow rapid penetration of the acid into the scale layer. In the case of corrosion resistant, austenitic and ferritic steels, which are inherently more difficult to pickle, strip annealing and mechanical pre-scaling achieve the best possible pickling strip surface. In order to do so, they are connected in series in the pickling process.
この種の方法或いは装置はドイツ特許第10022045号明細書(特許文献1)から公知である。そこには、ストリップが酸洗装備によって案内され、酸洗装備の前後にそれぞれ一つの圧延ユニットが配置されていることが開示されている。第二圧延ユニットの後部のストリップの搬送方向において、ストリップは焼き鈍し炉と引き続きスケールがストリップ表面から除去される酸洗槽とを通過する。既に仕上がったストリップの巻上げ前にこのストリップはプレス圧延機にて隔離して加工され得る。 A method or apparatus of this kind is known from DE 10022045 (Patent Document 1). There it is disclosed that the strip is guided by pickling equipment and one rolling unit is arranged before and after the pickling equipment. In the transport direction of the strip at the rear of the second rolling unit, the strip passes through an annealing furnace and subsequently a pickling tank in which the scale is removed from the strip surface. Prior to winding the already finished strip, this strip can be processed in isolation in a press mill.
国際特許出願公開第00/37189号明細書(特許文献2)と国際特許出願公開第00/37190号明細書(特許文献3)は、ストリップが少なくとも一つの複数スタンド圧延列にてストリップの厚さを減少される金属ストリップを製造する装置を開示する。引き続いてストリップは焼き鈍し炉に到達し、更なる過程においてストリップは酸洗装置によって案内される。ストリップの巻付け前にここで僅かな厚さ減少のみをストリップに処理する圧延操作が接続できる。 International Patent Application Publication No. 00/37189 (Patent Document 2) and International Patent Application Publication No. 00/37190 (Patent Document 3) describe the thickness of a strip in a multi-stand rolling row having at least one strip. An apparatus for manufacturing a metal strip that is reduced is disclosed. Subsequently, the strip reaches the annealing furnace and in the further process the strip is guided by a pickling device. A rolling operation can be connected here, in which only a slight thickness reduction is processed into the strip before winding of the strip.
米国特許出願公開第2001/0037667号明細書(特許文献4)は金属ストリップを製造する同様な装置を開示する。けれども、ここではストリップの加熱は企図されていない。ストリップは酸洗ラインにおけるスケール除去後のみに圧延機によって案内される。 U.S. Patent Application Publication No. 2001/0037667 discloses a similar apparatus for producing metal strips. However, heating of the strip is not contemplated here. The strip is guided by the rolling mill only after descaling in the pickling line.
既知の方法は、部分的にスケールを付けられた或いは単に部分的スケールを付けられた表面に圧延されなければならないと言う欠点を有する。このストリップ表面への圧延によってスケール除去された表面への圧延よりも本質的に高い圧延摩耗が生じる。さらに、それにより、表面品質が数倍要求されるような、表面品質が製造され得ないので、費用のかかる後処理が必要となる。 The known method has the disadvantage that it must be rolled to a partially scaled or simply partially scaled surface. This rolling to the strip surface results in essentially higher rolling wear than rolling to a scaled surface. In addition, it requires expensive post-processing because surface quality cannot be produced, such that several times the surface quality is required.
さらに、該当する方法の経済性を一べつすると、圧延機に続く装備とここで特に焼き鈍し炉と酸洗ラインは、圧延処理によって代表的には30ー40%だけ減少したストリップ厚さの規模に適合されなければならないことが極めて不都合であり、ストリップは既により薄いけれども、より長いので、焼き鈍し炉と酸洗ラインも適切に長く敷設されなければなず、何故なら、それは装置の高い費用をまねくからである。
この発明の課題は、前記欠点を克服することが可能であり、それで特にストリップの製造においてより高い生産性と経済性が達成され、更に仕上がったストリップの表面品質が改良されると言う最初に述べた種類の方法と付属装置を提供することにある。 The object of the present invention is the first to say that it is possible to overcome the above-mentioned drawbacks, so that higher productivity and economy are achieved, especially in the manufacture of strips, and the surface quality of the finished strip is improved. To provide different kinds of methods and attachments.
この発明によるこの課題の解決策は、この発明の方法により、圧延処理がストリップの加熱後に且つ化学的処理後に初めて実施されることを特徴とする。 The solution to this problem according to the invention is characterized in that, according to the method of the invention, the rolling process is only carried out after the strip has been heated and after the chemical treatment.
この処置態様によると、仕上げ装置において所望の厚さへのストリップの三処理工程圧延は酸洗によるストリップの焼き鈍し処理とスケール除去によってストリップの熱処理を実施していて、この場合に前記欠点が生じないことが達成される:元の厚さから減少した最終厚さまでのストリップの圧延は搬送方向において焼き鈍しと酸洗の後に初めて行われるから、焼き鈍し炉並びに酸洗ラインはそれぞれの範囲にてより小さく敷設され得る。さらに、前記圧延処理は完全にスケール除去されたストリップ表面に初めて行われるので、圧延摩耗が僅かなままである。さらに、提案された方法過程によって、改良されたストリップ表面品質は更なる処置が行使される必要なしに生じる。 According to this treatment mode, the three-process rolling of the strip to a desired thickness in the finishing device is performed by annealing the strip by pickling and heat treatment of the strip by descaling, in which case the above-mentioned disadvantages do not occur. Is achieved: the rolling of the strip from the original thickness to the reduced final thickness takes place only after annealing and pickling in the conveying direction, so the annealing furnace and pickling line are laid smaller in each area Can be done. Moreover, since the rolling process is first performed on a completely descaled strip surface, the rolling wear remains slight. Furthermore, with the proposed method process, improved strip surface quality occurs without the need for further treatment to be exercised.
特にストリップの加熱、ストリップの化学的処理及び圧延処理はこの順序で実施されることが提案されている。圧延処理の場合には特にテンダム圧延処理が重要である。一般に圧延処理の下でここでは、ストリップが圧延処理によってストリップ厚さを本質的に特に少なくとも20%だけ減少されることが理解される。既に述べたように、ストリップの化学的処理の際には酸洗処理が重要である。 In particular, it has been proposed that the heating of the strip, the chemical treatment of the strip and the rolling process be carried out in this order. In the case of a rolling process, the tendam rolling process is particularly important. In general, here it is understood that under the rolling process the strip is reduced in strip thickness essentially by at least 20% by the rolling process. As already mentioned, pickling is important during the chemical treatment of the strip.
金属の冷間加工されたストリップを連続的に製造するこの発明の装置は、ストリップを加熱する、即ち特に焼き鈍しする装備、ストリップを化学的処理する装備及びストリップを圧延する装備を有する。この発明によると、ストリップを圧延する装備はストリップを加熱する装備とストリップを化学的処理する装備との後に配置されていて、この場合にはストリップを圧延する装備は少なくとも一つのタンダム圧延列を有する。この圧延列はタイプ6本組高圧延機として或いはタイプZ本組高圧延機として形成され得る複数の圧延スタンドから成る。この圧延装備の外に、ストリップの厚さを減少するために別の装備は必要ではない。 The device according to the invention for continuously producing a cold-worked strip of metal comprises equipment for heating, i.e. in particular annealing the strip, equipment for chemically treating the strip and equipment for rolling the strip. According to the invention, the equipment for rolling the strip is arranged after the equipment for heating the strip and the equipment for chemically treating the strip, in which case the equipment for rolling the strip has at least one tandem rolling train . This rolling train consists of a plurality of rolling stands which can be formed as a type 6 high roll mill or as a type Z high roll mill. In addition to this rolling equipment, no other equipment is required to reduce the thickness of the strip.
品質を改良するために、さらにストリップを加熱する装備(焼き鈍し炉)とストリップを化学的処理する装備(酸洗ライン)との間に延伸指向性ユニットが配置され得る。さらに、焼き鈍し炉と酸洗ラインの間に金属粒放出ユニットが配置され得る。 In order to improve the quality, a stretch-directing unit can be arranged between the equipment for further heating the strip (annealing furnace) and the equipment for chemically treating the strip (pickling line). Furthermore, a metal grain discharge unit can be arranged between the annealing furnace and the pickling line.
搬送方向においてストリップを化学的処理する装備の後にさらに縁取りユニットがストリップを横に切り取るために配置されている。 After the equipment for chemically treating the strip in the transport direction, a further edging unit is arranged for cutting the strip sideways.
仕上げ装置によるストリップの出来るだけ均一な走行の厳守は、装置が少なくとも一つの特に三つのストリップ貯蔵部を有することによって容易とされる。 Strict adherence to as uniform running of the strips by the finishing device is facilitated by having at least one, in particular three strip reservoirs.
ストリップの生産量に応じて説明された仕上げ装置は一体化された圧延列(タンダム列)を備える組合せられた熱間と冷間の焼き鈍しと酸洗ラインとしても運転され得る。これを助成するために、追加的に搬送方向においてストリップを加熱する装備の前に、特に到着ストリップ貯蔵部の前に脱脂装備が配置され得る。 The finishing device described in accordance with the production of the strip can also be operated as a combined hot and cold annealing and pickling line with integrated rolling rows (tandum rows). To aid this, a degreasing equipment can additionally be arranged before the equipment for heating the strip in the conveying direction, in particular before the arrival strip storage.
図面においてこの発明の実施例が図示されている。唯一の図が概略的に特殊鋼を製造する装置を示す。 An embodiment of the invention is illustrated in the drawing. The only figure schematically shows an apparatus for producing special steel.
図において金属ストリップ1(金属ストランド)が加工される装置2が図示されている。この場合には、ストリップ1は搬送方向Rにおいて−即ち図の左から右へ−装置2によって案内され、この際にストリップ1の連続的進行(広範囲の一定のストリップ速度を備える進行)が行われる。
In the figure an
詳細に図示されていない流入部分13においてストリップ1は装置2に導入される。その場合にストリップ1は図示されていない巻解きユニットから巻解かれて、装置2に案内される。搬送方向Rにおいて脱脂装備12が接続し、その脱脂装備においてストリップ表面が清掃される。引き続いてストリップ1は、ストリップ1を加熱する装備3(焼き鈍し炉)の下に位置されているストリップ貯蔵部9(到着貯蔵部)に到達する。ストリップ貯蔵部9によって、ささいな外部障害の際にも、ストリップ導入においてストリップの連続的走行が達成されることが達成され得る。
The strip 1 is introduced into the
焼き鈍し炉3においてストリップ1は熱処理を受ける。引き続いてストリップは延伸指向性ユニット6にまで到達し、このユニットにおいてストリップ1が研磨される。延伸指向性ユニット6の後に金属粒放出ユニット7が配置されている。 In the annealing furnace 3, the strip 1 is subjected to a heat treatment. Subsequently, the strip reaches the stretch directional unit 6 in which the strip 1 is polished. A metal particle releasing unit 7 is disposed after the drawing directivity unit 6.
搬送方向Rにおいて金属粒放出ユニット7の後にはストリップ1を化学的処理する装備4が配置されている、即ちストリップ1が貯槽を通して案内される酸洗ラインは酸で充填されている。酸洗過程によってストリップ1の表面上のスケール層が除去されて、ストリップ1に改良された表面品質が与えられ得る。 In the conveying direction R, after the metal particle discharge unit 7, an equipment 4 for chemically treating the strip 1 is arranged, i.e. the pickling line in which the strip 1 is guided through the reservoir is filled with acid. The pickling process can remove the scale layer on the surface of the strip 1 to give the strip 1 an improved surface quality.
酸洗ライン4の下部にはストリップ貯蔵部11(中間貯蔵部)が配置されている。このストリップ貯蔵部からストリップ1は縁取りユニット8内に走行し、このユニットにおいてストリップ1の側面が切り取られる。この縁取りユニット8からストリップ1は一つの別のストリップ貯蔵部10(流出貯蔵部)を介してストリップ1を圧延する装備5にまで到達する。この圧延装備5はテンダム圧延列として形成されている。ここには三つの前後に配置された圧延スタンド5a,5b,5cが存在し、これら圧延スタンドではストリップ1が圧延されて、それによってストリップ厚さに減少される。
A strip storage unit 11 (intermediate storage unit) is disposed below the pickling line 4. From this strip reservoir, the strip 1 travels into the edging unit 8, where the side of the strip 1 is cut off. From this edging unit 8 the strip 1 reaches the equipment 5 for rolling the strip 1 via another strip storage 10 (outflow storage). The rolling equipment 5 is formed as a Tendam rolling train. Here there are three rolling
タンダム圧延列5の後部には流出部分14が配置されており、この流出部は図示されていない巻取りユニットを有し、その巻取りユニットにより仕上げられたストリップ1が巻取られ得る。 An outflow portion 14 is disposed at the rear of the tandam rolling row 5, and this outflow portion has a winding unit (not shown), and the strip 1 finished by the winding unit can be wound up.
タンダム圧延列5はー既に述べたようにー三つの圧延スタンド5a,5b,5cを有し、6本組高圧延機或いはZ本組高圧延機の複数圧延ー冷間圧延機の構成に形成され得る。ストリップ1の厚さ減少が装置2の端部にてストリップ1を圧延する唯一の装備5において初めて行われることによって、ストリップ1はタンダム圧延列5の前で比較的大きな厚さ、即ちストリップ1が装置2に入る厚さを有する。これは、焼き鈍し炉3並びに酸洗ライン4の構造長さが比較的僅かに保持され得ることをまねく。
The tandam rolling train 5 has three rolling
それによって装置2の投資費用を僅かに保つ装置2の比較的コンパクトな構成が生じる。焼き鈍し炉3並びに酸洗ライン4はストリップ1の元の厚さに敷設され得て、それによりストリップ1が装置2に入る。
This results in a relatively compact arrangement of the
少なくともオーステナイトと簡単なフェライト材料のために、厚さの減少が事前の焼き鈍しなしに処理され得る、それは最大30−40%のより少ない最大厚さの減少をまねく。 At least for austenite and simple ferrite material, the thickness reduction can be processed without prior annealing, which leads to a lower maximum thickness reduction of up to 30-40%.
装置2を通る一進行当たりのストリップ1の最大厚さ減少は、材料とタンダム圧延列5の出力のみに基づいており;焼き鈍しされていないストリップは、考慮される必要がない。
The maximum thickness reduction of the strip 1 per run through the
タンダム圧延列5の圧延スタンドは、最終焼き鈍しの際にストリップ1がプレスされ得るように敷設され得る。 The rolling stand of the tandam rolling row 5 can be laid so that the strip 1 can be pressed during the final annealing.
スケール除去した且つ特に既に切り取ったストリップは、装置2への接続において中間保管なしに均一なストリップ張力の下で連続的に次の装備(熱亜鉛引き装置など)に流入できる。その場合には仕上ったストリップは次の装備の後部に交換的に二つのリールに巻き取られ、シャーにより分割され得る。
