【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、圧延材の板端精度の向上を図り得るようにし
た圧延装置に関するものである。Description: [Industrial field of use] The present invention relates to a rolling apparatus capable of improving the plate edge accuracy of a rolled material.
圧延機において、一般に、第15図に示す如く、フラツト
な上下ワークロール(a)(a)で圧延材(b)を圧延すると、
圧延材(b)の幅端が板厚方向に不均一に変形した所謂バ
ルジング(c)が発生する。このバルジング(c)が発生する
と、次に圧延する時に側方に張出た幅端部分がロールに
接しないため、内側の材料が圧延で伸ばされるに従い内
側の材料から引張り力を受けて長手方向に延伸され、そ
うしてバルジング(c)が発生した幅端部にはクラツクが
発生し易くなり、板切れの原因ともなる。In a rolling mill, generally, as shown in FIG. 15, when rolling a rolled material (b) with flat upper and lower work rolls (a) (a),
A so-called bulging (c) in which the width end of the rolled material (b) is deformed unevenly in the plate thickness direction occurs. When this bulging (c) occurs, the width end that flanks sideways does not come into contact with the rolls during the next rolling, so as the inner material is stretched by rolling, it receives a tensile force from the inner material and the longitudinal direction. Thus, cracks are likely to occur at the width end portion where the bulging (c) is generated, which also causes a plate break.
そこで従来、第16図及び第17図に示すように、上下ワー
クロール(a)(a)の両端部に、環状の溝(d)を夫々上下で
対向して設け、これらの溝(d)に側面ガイド板(e)を嵌入
させて圧延材(b)を圧延するようにした方式が開発され
た。このようにすると、側面ガイド板(e)によつて圧延
材(b)の幅広がりが拘束され幅端部の矩形化を図ること
ができる。Therefore, conventionally, as shown in FIGS. 16 and 17, at both ends of the upper and lower work rolls (a) and (a), annular grooves (d) are provided so as to face each other vertically, and these grooves (d) are provided. A method has been developed in which a side guide plate (e) is fitted into the rolled material and the rolled material (b) is rolled. With this configuration, the lateral guide plate (e) restrains the width spread of the rolled material (b), and the width end portion can be made rectangular.
しかしながら、斯かる従来方式においては、上下ワーク
ロール(a)(a)に設けた溝(e)の位置が固定であるため、
１種類の圧延材(b)にしか適用できない問題があつた。
又、側面ガイド板(e)は圧延材(b)の幅方向への変形を拘
束してはいるものの、位置固定であることから、積極的
に圧延材(b)の幅を縮めるための調節はできず、更に圧
延材(b)の入側部分に狭幅部分があつても、追従して矩
形断面に加工することはできなかつた。However, in such a conventional method, since the position of the groove (e) provided in the upper and lower work rolls (a) (a) is fixed,
There was a problem that it could only be applied to one type of rolled material (b).
Also, the side guide plate (e) restrains the deformation of the rolled material (b) in the width direction, but since the position is fixed, adjustment for positively reducing the width of the rolled material (b) is made. However, even if there was a narrow portion on the entrance side of the rolled material (b), it was not possible to follow it and process it into a rectangular cross section.
本発明はこのような実情に鑑み、積極的に圧延材の幅変
形量を制御し得るようにしたものである。In view of such a situation, the present invention is capable of positively controlling the width deformation amount of the rolled material.
本発明の圧延装置は、上下のワークロール間の位置に、
圧延材の幅端面と接する一対のガイド部材を、圧延材の
幅方向へ移動可能に配設し、各ガイド部材に圧延材の幅
端面を押圧させる押付装置を接続した構成としている。The rolling apparatus of the present invention, at the position between the upper and lower work rolls,
A pair of guide members that are in contact with the width end surface of the rolled material is disposed so as to be movable in the width direction of the rolled material, and a pressing device that presses the width end surface of the rolled material is connected to each guide member.
従つて、圧延材の幅端面変形量が押付装置によつて積極
的に制御される。Therefore, the width end face deformation amount of the rolled material is positively controlled by the pressing device.
先ず、本発明の基礎理論を説明すると、第12図及び第13
図に示すような上下のワークロール(1)(1)で入側板厚2.
2mmの圧延材（この場合鋼板）(2)を圧延する時に発生す
るエツジドロツプＥＤ（＝hA−hE）と幅広がりΔＢは、
圧延領域（クロスハツチング部）内の圧延材(2)幅端部
に外力FZを加えると、第14図に示すように変化する。即
ち、FZ＝０の状態では幅広がりΔB、エツジドロツプED
共に存在する。そこで、FZを加え、例えばFZ≒500Kgで
はΔB≒０となるがEDはまだ存在する。FZ≒1000Kgにす
るとED≒０となるが、ΔBは約0.7mmの幅縮みとなる。First, the basic theory of the present invention will be described.
The upper and lower work rolls (1) (1) as shown in the figure make the entry side plate thickness 2.
The edge drop ED (= h A −h E ) and the width spread ΔB generated when rolling a 2 mm rolled material (steel plate in this case) (2) are
When an external force F Z is applied to the width end portion of the rolled material (2) in the rolling region (cross hatching portion), it changes as shown in FIG. That is, in the state of F Z = 0, the width spread ΔB, the edge drop ED
Exist together. Therefore, if F Z is added, and for example, F Z ≈500 Kg, ΔB≈0, but ED still exists. When F Z ≈ 1000 Kg, ED ≈ 0, but ΔB has a width reduction of about 0.7 mm.
以上から解るように、FZによつてΔB、EDは大きな影響
を受け、従来のようにΔB≒０の圧延をしてもEDとして
は目的の値以下に減らせないことがある。従つて、FZを
最適な値に設定し得る圧延機が望ましい。As can be seen from the above, ΔB and ED are greatly affected by F Z , and even if rolling is performed with ΔB≈0 as in the conventional case, the ED may not be reduced below the target value. Therefore, a rolling mill that can set F Z to an optimum value is desirable.
次に、具体的な実施例を説明する。Next, specific examples will be described.

The external force F Z can be applied to. Further, based on the edge drop amount of the rolled material (2) after rolling and a plate width detector (not shown), the external force F Z is controlled so that these values are optimum, or the characteristics shown in FIG. 14 are obtained in advance. , You may decide the optimum F Z and always keep F Z at that value.
