えられていた。Conventionally, among these defects, center segregation, in particular, always occurs when attempting to cast A, &-Mg alloys, etc., which have a wide solidification temperature range, by twin roll casting. This is due to the following reasons. In other words, even in normal thick-walled ingots, concentration segregation of solute elements occurs in the final solidified part, but especially in the case of twin-roll casting, there is unsolidified molten metal inside before solidification is completed. Since the cast plate in this state is subjected to reduction by rolling, the concentration segregation area in front of the solidification completion chamber is pushed back, and the concentration segregation of solute elements becomes extremely significant. As a result, extreme concentration segregation occurs at the center of the plate thickness, resulting in center segregation defects. This was conventionally thought to be an inherent problem in twin roll casting technology.

, 2 are arranged with their axes parallel to each other and vertically opposed to each other with appropriate length intervals. The rolls 1 and 2 have a cylindrical shape with a constant shell thickness t, and a cooling member 3 through which cooling water flows is fixed to the inner peripheral surface thereof. As the cooling water flows back through the cooling member 3, the shell of the roll 1.2 is cooled.

This nozzle 4 is connected to a molten metal supply source such as a molten metal pot, and molten aluminum alloy 5 is injected into the gap between the rolls 1 and 2 through this nozzle 4.

なされた。しかしながら、従来、何れの方法でも中心偏
析を軽減することができなかった。The reason for this will be explained below. A,! In alloys with a wide solidification temperature range, such as 12-Mg alloys, concentration segregation tends to occur in the center. However, even in such an alloy, concentration segregation can be prevented by making the cooling rate extremely fast. Therefore, even in the twin roll casting method,
Since the molten aluminum alloy 5 is cooled by contact with the casting rolls 1 and 2, in order to increase the cooling rate, copper shells are used for the casting rolls 1 and 2, and cooling water flowing inside the rolls is used. Attempts were made to lower the water temperature. However, none of the conventional methods has been able to reduce center segregation.
本願発明者等は、この原因について究明すべく種々実験
研究を重ねた結果、以下の知見を得た。The inventors of the present application have conducted various experimental studies to find out the cause of this, and have obtained the following knowledge.
即ち、アルミニウム合金溶湯の凝固時の熱拡散（冷却）
の律速過程は、従来、冷却水とロールシェルとの間であ
ると考えられていたが、本願発明者等は冷却水とシェル
との間ではなく溶湯とロールシェルとの間の熱伝達が凝
固時の熱拡散を律速していることに想到した。That is, thermal diffusion (cooling) during solidification of molten aluminum alloy.
Conventionally, the rate-determining process was thought to be between the cooling water and the roll shell, but the inventors of the present application believe that the heat transfer between the molten metal and the roll shell solidifies, not between the cooling water and the shell. I came up with the idea that this controls the rate of heat diffusion over time.
薄いシェル厚のロールを使用し低温の冷却水を流した場
合、溶湯を供給しない非鋳造時にはシェル自体はよく冷
える。このため、アルミニウム合金溶湯がロールに接触
すると、その表面層は急激に凝固するが、ロールのシェ
ルは薄くて熱容量が小さいため、ロールシェルの表面が
容易に１００℃以上に加熱されてしまい、ロールシェル
と冷却水との界面に水蒸気膜が形成されて両者間が断熱
状態となる。従って、この場合、鋳造板の板厚方向の中
央部は徐冷したのと同様の状態となり、濃度偏析が極め
て激しくなる。If a roll with a thin shell is used and low-temperature cooling water is flowed through it, the shell itself will cool down well when molten metal is not being supplied and the roll is not being cast. For this reason, when the molten aluminum alloy comes into contact with the roll, its surface layer rapidly solidifies, but since the roll shell is thin and has a small heat capacity, the surface of the roll shell is easily heated to over 100°C, and the roll A water vapor film is formed at the interface between the shell and the cooling water, creating an adiabatic state between the two. Therefore, in this case, the central portion of the cast plate in the thickness direction is in a state similar to that of slow cooling, and concentration segregation becomes extremely severe.
これに対して、厚いシェルを使用した場合は、冷却水に
よるシェルの冷却能は小さいが、シェル自体の熱容量が
大きいため、前述の水蒸気膜による断熱状態に到達する
前に凝固が完了する。このため、シェル厚が厚いロール
を使用すれば、板厚の中央部まで速い冷却速度で凝固さ
せることができる。On the other hand, when a thick shell is used, although the cooling ability of the shell by cooling water is small, the heat capacity of the shell itself is large, so solidification is completed before the adiabatic state due to the water vapor film described above is reached. For this reason, if a roll with a thick shell is used, it is possible to solidify at a high cooling rate up to the center of the thickness of the plate.
本願発明者等は、かかる観点に立って、本発明を完成さ
せるに至ったものである。上述の如く、鋳造板の板厚方
向中央部まで高冷却速度で冷却させるのに十分なシェル
の熱容量を確保するために、シェル厚を３５ｍｍ以上に
する。シェル厚が３５ｍｍ未満の場合には、シェルとア
ルミニウム合金溶湯との間が水蒸気膜により断熱状態と
なり易く、中心偏析が著しくなる。従って、シェル厚は
３５ｍｍ以上であることが必要である。The inventors of the present application have completed the present invention based on this viewpoint. As described above, the shell thickness is set to 35 mm or more in order to ensure sufficient heat capacity of the shell to cool down to the central part in the thickness direction of the cast plate at a high cooling rate. When the shell thickness is less than 35 mm, the space between the shell and the molten aluminum alloy is likely to be insulated due to a water vapor film, resulting in significant center segregation. Therefore, the shell thickness needs to be 35 mm or more.
また、シェル厚の上限は６０ｍｍとする。シェル厚が６
０ｍｍを超えると、逆に熱容量が大き過ぎ、ロール１回
転の間の冷却時間（鋳造完了から次項のアルミニウム合
金溶湯と接触するまでの時間）内に、シェル内面の冷却
部材３による冷却の効果がシェル外面にまで到達せず、
シェル表面（外面）が十分に冷却されない状況となる。Further, the upper limit of the shell thickness is 60 mm. Shell thickness is 6
If it exceeds 0 mm, the heat capacity will be too large, and the cooling effect by the cooling member 3 on the inner surface of the shell will be lost during the cooling time for one rotation of the roll (the time from completion of casting to contact with the molten aluminum alloy described in the next section). does not reach the outer surface of the shell,
This results in a situation where the shell surface (outer surface) is not sufficiently cooled.
その結果、鋳造板７の表面の凝固が遅れ、表面品質が低
下する。As a result, the solidification of the surface of the cast plate 7 is delayed and the surface quality is degraded.
従って、ロールのシェル厚は６０ｍｍ以下とすることが
必要である。なお、アルミニウム合金溶湯の冷却速度及
びシェルの冷却条件を一層厳密にコントロールしようと
する場合には、シェル厚は４０關以上５５ｍｍ以下にす
ることが望ましい。Therefore, it is necessary that the shell thickness of the roll be 60 mm or less. In addition, when attempting to control the cooling rate of the molten aluminum alloy and the cooling conditions of the shell more strictly, it is desirable that the shell thickness is 40 mm or more and 55 mm or less.
シェルの材質は熱容量が大きくなるように比熱が大きい
ものである方が好ましい。また、双ロール式鋳造設備は
、ロール１，２が鋳造板７を圧延する機能も有している
設備であるため、ロールシェルにはこのような鋳造板の
圧延に耐えられる程度の硬度が必要である。このような
理由で、ロールシェルには耐熱鋼等を使用することが望
ましい。It is preferable that the material of the shell has a large specific heat so as to have a large heat capacity. In addition, since the twin roll casting equipment is equipment in which rolls 1 and 2 also have the function of rolling the cast plate 7, the roll shell must have a hardness that can withstand the rolling of such a cast plate. It is. For these reasons, it is desirable to use heat-resistant steel or the like for the roll shell.
また、冷却時間については、約９０ｃｍ径のロールの場
合には１．５分以上の冷却時間をとることが望ましい。Further, regarding the cooling time, in the case of a roll having a diameter of about 90 cm, it is desirable to take a cooling time of 1.5 minutes or more.
上述の範囲に規定したシェル厚の場合には、通常のアル
ミニウム合金鋳造板の鋳造条件の範囲内（約８０乃至１
８０ｃｍ／分のロール周速度〉であれば冷却時間につい
ては全く問題がない。In the case of shell thickness specified in the above range, it is within the range of casting conditions for ordinary aluminum alloy cast plates (approximately 80 to 1
If the roll circumferential speed is 80 cm/min, there is no problem with the cooling time.
以下、本発明の実施例に係る鋳造装置の鋳造ロールを使
用して実際に鋳造板を製造した結果について説明する。Hereinafter, the results of actually manufacturing a cast plate using the casting roll of the casting apparatus according to the embodiment of the present invention will be described.
