【発明の詳細な説明】 〈産業上の利用分野〉 本発明は高形状精度条の圧延方法に関する。[Detailed description of the invention] <Industrial application field> The present invention relates to a method for rolling a strip with high shape accuracy.
〈従来技術およびその問題点〉
一般に高形状精度条の圧延方法は、例えば第４
図に示すように、送り出し装置３から図中右方向
に条を送り出し、この条を圧延ロール１にて圧延

通常、圧延ロール１と巻取り装置４との間に圧延

と搬送方向が変る部分の２カ所に配設してある
が、実際にはいずれか一方でよい。<Prior art and its problems> In general, the rolling method for high shape precision strips is, for example, the fourth method.
As shown in the figure, a strip is sent out from a feeding device 3 toward the right in the figure, and this strip is rolled with a rolling roll 1 to form a rolled strip 2, which is then wound up with a winding device 4.
Usually, a shape measuring device 5 for the rolled strip 2 is arranged between the rolling roll 1 and the winding device 4 to measure the shape of the strip during rolling, and the measurement results are fed back to the rolling conditions to measure the shape between the upper and lower rolling rolls. By changing the gap, we are able to obtain strips with high shape accuracy. In FIG. 4, the shape measuring device 5 is disposed at two locations, the horizontal conveyance portion of the rolled strip 2 and the portion where the conveyance direction changes, but in reality, either one may be used.
圧延される条の厚さが薄くなつたり、幅が広く
なつたりしてくると、圧延ロール１の圧延荷重に
よる変形、熱膨張、その他の要因により、圧延条
２の形状が部分的に波を打つたりしやすくなり、
高形状精度条を得るのが困難となる。 As the thickness of the rolled strip becomes thinner or the width becomes wider, the shape of the rolled strip 2 becomes partially wavy due to deformation due to the rolling load of the rolling roll 1, thermal expansion, and other factors. It becomes easier to hit,
It becomes difficult to obtain strips with high shape accuracy.
そのため、圧延中に条の形状を形状測定装置５
で測定し、その測定結果を圧延条件にフイードバ
ツクして、上下圧延ロール１間のギヤツプを変え
たり、圧延ロール１の変形状態を変えたりして高
形状精度条を得ている。 Therefore, the shape of the strip is measured by the shape measuring device 5 during rolling.
The measurement results are fed back to the rolling conditions, and the gap between the upper and lower rolls 1 is changed or the deformation state of the rolls 1 is changed to obtain a strip with high shape accuracy.
しかし実際の圧延においては、波打ち形状など
が圧延条２にできても、圧延中は圧延ロール１と
巻取り装置４との間の圧延条２の部分Ｄに大きな
張力（応力）がかかつている場合が多く、その影
響で圧延条２は長さ方向に伸ばされ、外観上、波
打ち形状が現出しない。 However, in actual rolling, even if the rolled strip 2 has a wavy shape, a large tension (stress) is applied to the portion D of the rolled strip 2 between the rolling roll 1 and the winding device 4 during rolling. In many cases, the rolled strip 2 is stretched in the length direction due to this influence, and the wavy shape does not appear in appearance.
そこで、このような場合の形状測定技術が種々
開発され、実用化されており、条の幅方向の張力
分布が異なることを利用してその幅方向の張力を
分割して測定する方法や、条に対して直角方向に
外力を加えてたるみを顕在化し、その幅方向の分
布を測定する方法や、条に直角方向に振動を加え
てその振幅または固有振動数の幅方向の分布を測
定する方法などがある。 Therefore, various shape measurement techniques for such cases have been developed and put into practical use. A method in which an external force is applied perpendicular to the strip to reveal the sag, and its distribution in the width direction is measured, or a method is applied in a direction perpendicular to the strip and the distribution of its amplitude or natural frequency in the width direction is measured. and so on.
しかしこれらの方法は、潜在化している形状不

がある。 However, these methods are technically difficult to measure latent shape defects, the measurement methods are complicated, the measurement equipment is expensive, and there are limits to measurement accuracy. There is a problem.

A method for rolling a strip with high shape accuracy is provided, which is characterized in that the shape of the rolled strip is measured in the rolled strip portion under low tension, and the measurement results are fed back to the rolling conditions.
以下、本発明の好適実施例について、添付図面
に基づいて説明する。 Hereinafter, preferred embodiments of the present invention will be described based on the accompanying drawings.
第１図に示すように、送り出し装置３から図中
右方向に条を搬送し、この条を圧延ロール１にて
圧延して圧延条２とし、形状測定装置５を介して
巻取り装置４にて巻取るが、本発明においては、
圧延ロール１と巻取り装置４との間、より詳しく
は圧延ロール１と形状測定装置５との間に、一組
のブライドルロール６が配設されている。 As shown in FIG. 1, a strip is conveyed from a feeding device 3 to the right in the figure, rolled by a rolling roll 1 to form a rolled strip 2, and then sent to a winding device 4 via a shape measuring device 5. However, in the present invention,
A set of bridle rolls 6 is arranged between the rolling roll 1 and the winding device 4, more specifically between the rolling roll 1 and the shape measuring device 5.
ブライドルロール６は複数個、例えば５個のロ
ールを備え、各ロールの間を圧延条２を巻掛けて
搬送するようになつており、このブライドルロー
ル６により圧延ロール１とブライドルロール６と
の間の圧延条２の部分Ａに必要な張力f1が加えら
れる。 The bridle roll 6 includes a plurality of rolls, for example, five rolls, and the rolled strip 2 is wound around and conveyed between each roll. A necessary tension f 1 is applied to part A of the rolled strip 2 of .
そして、ブライドルロール６を経て巻取り装置
４に巻取られる圧延条２の部分Ｂに対しては、巻
取り装置４によつて、所要の小さな張力f2が加え
られる。ブライドルロール６に巻掛けて搬送する
ことにより、ここで巻取り装置４による圧延条２
への張力が低減され、張力f1＞f2となる。 Then, a required small tension f 2 is applied by the winding device 4 to the portion B of the rolled strip 2 that is wound up by the winding device 4 via the bridle roll 6 . By winding it around the bridle roll 6 and conveying it, the rolled strip 2 is rolled by the winding device 4.
The tension on is reduced, and the tension becomes f 1 > f 2 .
よつて、圧延条２の部分Ｂ（張力f2）において
は、圧延条２の長さ方向に必要以上に引張られる
ことがなく、そのため、形状不良に伴う波打ち形
状がある場合はそれが顕在化して現出し、形状測
定装置５による形状測定が容易になる。 Therefore, the portion B (tension f 2 ) of the rolled strip 2 is not pulled more than necessary in the length direction of the rolled strip 2, and therefore, if there is a wavy shape due to a shape defect, it becomes obvious. This makes shape measurement by the shape measuring device 5 easier.
また、形状不良が完全に顕在化しなくても、圧
延条２の部分Ｂにかかる張力f2が小さくなること
により、形状測定が容易になる。 Further, even if the shape defect does not become completely apparent, the shape measurement becomes easier because the tension f 2 applied to the portion B of the rolled strip 2 is reduced.
すなわち、第３ｂ図に示される従来方法の場合
のように、圧延条２の部分Ｄの長さ方向に大きな
張力が加わつていると、幅方向の位置による張力
分布が存在しても、平均値に対する変化率が小さ
いので、測定技術も高度になり、測定精度上も困
難が伴う。 That is, when a large tension is applied in the length direction of the portion D of the rolled strip 2, as in the case of the conventional method shown in FIG. 3b, even if there is a tension distribution depending on the position in the width direction, the average value Since the rate of change is small, measurement techniques must be sophisticated, and measurement accuracy is also difficult.
一方、第３ａ図に示されるように本発明の場合
は圧延条２の部分Ｂの長さ方向の張力の平均値が
小さくなるため、幅方向の位置による張力分布の
平均値に対する変化率が大きくなり、従つて測定
が容易になり、測定精度も向上しやすい。 On the other hand, as shown in Fig. 3a, in the case of the present invention, the average value of the tension in the length direction of portion B of the rolled strip 2 is small, so the rate of change in the tension distribution with respect to the average value depending on the position in the width direction is large. Therefore, measurement becomes easy and measurement accuracy tends to improve.
このように張力分布の測定による場合は、波打
ち等の形状不良が顕在化しない範囲でできるだけ
小さい平均張力を選ぶのがよい。 When measuring the tension distribution as described above, it is preferable to select an average tension that is as small as possible within a range where shape defects such as waving do not become apparent.
また、張力分布の測定による場合でなく、圧延
条に直角方向に外力を加えて幅方向のたるみ分布
を測定する方法においても、全く同様のことがい
える。 Furthermore, the same thing can be said for a method in which the sag distribution in the width direction is measured by applying an external force to the rolled strip in a direction perpendicular to the rolled strip, instead of measuring the tension distribution.
また形状不良を顕在化させて形状測定を行なう
場合は、少なくとも許容されない波打ち等の形状
不良が潜在化しない程度に平均張力を小さく選ぶ
ことが必要である。 In addition, when performing shape measurement with shape defects exposed, it is necessary to select a small average tension at least to the extent that shape defects such as unacceptable waving do not become latent.
顕在化させた形状の測定は、光学的方法や、渦
電流式センサを幅方向に何個か設置する方法など
種々の方法が適用できる。 Various methods can be applied to measure the revealed shape, such as an optical method and a method of installing several eddy current sensors in the width direction.
第２図はブライドルロールを二組配設した例
で、前述の第１図のものに、形状測定装置５と巻
取り装置４との間に第２のブライドルロール７を
配設したものである。 FIG. 2 shows an example in which two sets of bridle rolls are arranged, in which a second bridle roll 7 is arranged between the shape measuring device 5 and the winding device 4 in addition to the one shown in FIG. 1 described above. .
第２のブライドルロール７は複数、例えば３個

ドルロール６に巻掛けられて搬送された圧延条２

ドルロール６，７間の圧延条部分Ｃにかかる張力

圧延条２の部分Ｃに配設された形状測定装置５に
よる形状測定がさらに容易になる。 The second bridle roll 7 includes a plurality of rolls, for example, three rolls, and the rolled strip 2 wound around the first bridle roll 6 and conveyed between each roll.
is wound again and conveyed to the winding device 4, and as a result, compared to the case shown in FIG. Due to the two-stage winding of the bridle rolls 6 and 7, the tension applied to the rolled strip portion C between these bridle rolls 6 and 7 is further reduced than the tension f2, so that The shape measurement by the shape measuring device 5 made easier.
なお、第１図および第２図において、往復圧延
する場合は、送出し装置と巻取り装置がその都度
逆の役目をするので、その場合には圧延ロールの
両側にブライドルロールを配置すればよい。 In addition, in FIGS. 1 and 2, when reciprocating rolling is performed, the feeding device and the winding device perform opposite roles each time, so in that case, bridle rolls may be placed on both sides of the rolling roll. .
