ミニウム合金硬質板の製造に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to the production of AI-Mn-MQ aluminum alloy sheets with excellent deep drawability, and particularly to the application of coating at any forming stage, regardless of whether before or after product forming. The present invention relates to the production of aluminum alloy hard plates with excellent drawability and strength for aluminum alloy plates to be subjected to baking treatment.

ることから使用されてきた。Conventional technology Conventionally, aluminum alloy plates for deep drawing are usually
14, rolling reduction ratio of finish cold rolling 30-50%
A semi-rigid plate, a semi-soft plate indicated by H24, or a fully annealed plate indicated by 0 have been used because they have excellent deep drawability.
近年、製品成形技術の進歩と共に、圧下率が50%を越
える仕上げ冷間圧延で得られる硬質板が深絞り用に利用
されるようになった。これは、より高い強度の合金材を
用いて製造した薄板を使うことによる経済的利益が大き
な理由である。In recent years, with advances in product forming technology, hard plates obtained by finish cold rolling with a rolling reduction of more than 50% have come to be used for deep drawing. This is largely due to the economic benefits of using sheets made from higher strength alloy materials.
A 3004ニ代表されるAI −Mn−Mg系アルミ
ニウム合金は、硬質板に用いたとき強度、成形性が比較
的良好であることが知られており、この硬質板は缶、た
る等深絞り成形品に多く利用されている。The AI-Mn-Mg aluminum alloy represented by A 3004 is known to have relatively good strength and formability when used in hard plates, and these hard plates can be deep drawn for cans, barrels, etc. It is used in many products.
このような硬質板は、熱間圧延−(冷間圧延)−中間焼
鈍−最終冷間圧延からなる工程で、中間焼鈍を350℃
〜450℃で0.5〜3時間時間色し、最終冷間圧延の
圧下率を70〜85%として製造している。このように
して製造された硬質板は、缶などの製品の成形工程の前
又は後で、塗装焼付は処理が施されることが多い。Such hard plates are produced by a process consisting of hot rolling, cold rolling, intermediate annealing, and final cold rolling, with intermediate annealing at 350°C.
The product is colored at ~450°C for 0.5~3 hours, and the final cold rolling reduction is 70~85%. Hard plates manufactured in this manner are often subjected to paint baking treatment before or after the process of forming products such as cans.
が解決しようとする問題点
従来技術において、前記のとおり高強度の薄板を求める
観点からみれば、仕上げ冷開圧延圧下率を80〜90%
に高めて得る、いわゆるH2O材(超硬質板)の利用が
好ましい。しかし、゛仕上げ冷間圧延の圧下率を増して
硬く(強化)した板は、同時に成形性が低下するので、
成形性の点からは好ましくない、という問題があった。Problems to be Solved In the conventional technology, as mentioned above, from the viewpoint of obtaining a thin plate with high strength, the finishing cold opening rolling reduction ratio is 80 to 90%.
It is preferable to use a so-called H2O material (super hard plate) obtained by increasing the hardness. However, if the plate is made harder (strengthened) by increasing the reduction rate during finish cold rolling, the formability will also decrease.
There was a problem in that it was unfavorable from the point of view of moldability.
本発明は、H2O材に相当する強度を有するとともに、
成形性が格段に良い深絞り用アルミニウム合金板を製造
することができる。その製造方法を提供することを目的
とするものである。The present invention has strength equivalent to H2O material, and
It is possible to produce an aluminum alloy plate for deep drawing with much better formability. The purpose of this invention is to provide a manufacturing method thereof.
問題点を解決するための手段
本発明は、前記目的を達成するために、以下のとおり構
成される。Means for Solving the Problems In order to achieve the above object, the present invention is configured as follows.
すなわち、本発明は、深絞り用アルミニウム合金板の製
造方法として、Si : 0.1〜1%、Mg :
0.2〜2%、Mn: 0.2〜2%、Cu:0.
1〜0.3%、Zn 二0.005〜0.2%を含み、
残部が実質的にAlであるアルミニウム合金鋳塊を均質

でこの板に、500℃〜600℃に5秒〜5分保持後急
冷することからなる溶体化処理を施した後、圧下率30
〜70%の最終冷間圧延を施すものである。That is, the present invention provides a method for producing an aluminum alloy plate for deep drawing, in which Si: 0.1 to 1%, Mg:
0.2-2%, Mn: 0.2-2%, Cu: 0.
1 to 0.3%, Zn2 0.005 to 0.2%,
After homogenizing an aluminum alloy ingot in which the remainder is substantially Al, it is hot-rolled and cold-rolled into a plate, which is then held at 500°C to 600°C for 5 seconds to 5 minutes and then rapidly cooled. After solution treatment consisting of
~70% final cold rolling is performed.
以下、本発明の構成を詳しく説明する。Hereinafter, the configuration of the present invention will be explained in detail.
各合金成分は、アルミニウムの強度を高めるように添加
するものであるが、特に強度を支配する成分はMQ 、
Mn 、 Siである。Mgと3iはMIl12Siな
る微細化合物を形成することにより強度を高める。Each alloy component is added to increase the strength of aluminum, but the components that particularly dominate the strength are MQ,
Mn and Si. Mg and 3i increase the strength by forming a fine compound called MIl12Si.
CuとZnは、Mo −Cu−Zn化合物を形成するこ
とで強度を高めるとともに、成形性の向上に寄与する。Cu and Zn increase strength by forming a Mo-Cu-Zn compound and contribute to improving moldability.
Mnは、高温からの急冷と焼戻し処理によって微細析出
物を生成するが、これによる強度への影響は、前記合金
成分はどでない。Mn forms fine precipitates when rapidly cooled from high temperatures and tempered, but this does not affect the strength of the alloy components.
これら各成分はいづれも前記の下限より少なければ強度
が不十分となり、前記の上限を越゛えると粗大化合物を
生成して成形性を低下させ、また硬くなりすぎて成形不
良を起こすので好ましくない。なお、znは更に板の塗
装焼付は処理後の強度を上げるのに役立つ。If each of these components is less than the lower limit, the strength will be insufficient, and if it exceeds the upper limit, coarse compounds will be formed, reducing moldability, and it will become too hard, causing molding defects, which is not desirable. . Furthermore, zn is useful for increasing the strength of the board after the coating is baked.
従来の硬質板ないし超硬質板の製造では、最終冷間圧延
を70〜85%の圧下率で行なっている。In the conventional production of hard plates or ultra-hard plates, the final cold rolling is performed at a rolling reduction of 70 to 85%.
しかし、これによって製造された硬質板は、最終冷間圧
延の圧下量が大きいので、その強度は高いものの、深絞
り性が良くない。However, the hard plate manufactured by this method has a large reduction amount in the final cold rolling, so although its strength is high, its deep drawability is not good.
これに対し、本発明により、500℃〜600℃に5秒
〜5分間保持してから急冷する、いわゆる溶体化処理を
中間焼鈍として行なうことによって、30〜70%の最
終冷間圧延圧下層で、従来の70%を越す圧下量による
硬質板並みの強度を、深絞り性を損なうことなしに、得
ることが可能となった。In contrast, according to the present invention, by holding the temperature at 500°C to 600°C for 5 seconds to 5 minutes and then rapidly cooling it, so-called solution treatment is performed as intermediate annealing. , it has become possible to obtain strength comparable to that of a hard plate by reducing the amount of reduction exceeding 70% of the conventional strength without impairing deep drawability.
なお、焼鈍温度への昇温速度を5℃/秒以上にし、15
0℃以下への冷却速度を5℃/秒以上とするのが望まし
い。焼鈍温度が500℃より低く、保持時間が5秒より
短いと、所要の強度が得られない。一方、600℃より
高温にすると板の融解を起こし、また5分より長く保持
しても得られる強度は変らないため、経済的に不利であ
る。In addition, the temperature increase rate to the annealing temperature should be 5°C/sec or more, and 15
It is desirable that the cooling rate to below 0°C be 5°C/sec or more. If the annealing temperature is lower than 500°C and the holding time is shorter than 5 seconds, the required strength cannot be obtained. On the other hand, if the temperature is higher than 600°C, the plate will melt and the strength obtained will not change even if the plate is held for longer than 5 minutes, which is economically disadvantageous.
最終冷間圧延の圧下率が30%より低いと、従来の硬質
板に相当する強度が得られず、一方、圧下率が70%を
越えるほど高くすると、深絞りの際に発生する板の耳が
大きくなって好ましくない。最適範囲は40〜60%で
ある。If the reduction rate in the final cold rolling is lower than 30%, it will not be possible to obtain the strength equivalent to that of a conventional hard plate. becomes large, which is not desirable. The optimal range is 40-60%.

処理により強度が低下する。According to the present invention, an aluminum alloy intermediate plate before final rolling is solution-treated and then finally cold-rolled to obtain a hard plate material. , if the paint baking at 150 to 220°C is treated, this treatment works in conjunction with the solution treatment according to the present invention, and the similar baking is equivalent to or higher than that of the conventional hard plate treated. strength can be obtained. In other words, since the amount of reduction in the final cold rolling is small, the as-rolled sheet is relatively soft and has good formability, and the subsequent baking reduces the strength when subjected to treatment, or The treatment causes age hardening and increases strength. As a result, the strength of the paint baking is equal to or higher than that of the conventional 819 board which has been treated. With conventional hard boards, the strength of paint baking decreases due to treatment.
