Abstract

PURPOSE:To control the amount of width deformation of a rolling stock, by constituting the titled equipment by arranging guide members at both sides of work rolls used for rolling a sheet so that the members are in contact with the width-end faces of the stock and connecting pushing devices to the members respectively. CONSTITUTION:Upper and lower work rolls 1, 1 are provided slidably in their axial directions, and annular grooves 3 are provided to the right and left sides of the bodies of rolls 1, 1 respectively. A side guide-plate 4 is inserted into each groove 3, and is pressed against the outer circumferential surface of the opposite-side roll 1 through rolls 5 by hydraulic cylinders 6. In rolling operation, an external force FZ is applied to the guide plate 4 by pressing devices 7 through rod members 8, to control positively the amount of width deformation of a rolling stock 2. In this way, the amount of width deformation of the stock 2 can be controlled, and the stock 2 is prevented from causing the peculiar defects of its edge part.

【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９得るようにし
た圧延装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rolling apparatus that improves the plate edge accuracy of rolled material as shown in FIG.

〔従来の技術〕[Conventional technology]

もなる。In a rolling mill, when a rolled material (6) is generally rolled with flat upper and lower work rolls (8) (α) as shown in Fig. 15, the width end of the rolled material (b) becomes uneven in the thickness direction. Deformed so-called bulging (c) occurs. When this bulging (c) occurs, the width end portion that protrudes to the side does not come into contact with the rolls during the next rolling, so as the inner material is stretched during rolling, it receives tensile stress from the inner material in the longitudinal direction. Cracks are likely to occur at the width end portions where bulging (c) has occurred due to stretching, which may cause the board to break.

かった。Therefore, conventionally, as shown in FIGS. 16 and 17, annular grooves (d) are formed at both ends of the upper and lower work rolls (α) (a).
A method has been developed in which the rolling material (6) is rolled by providing upper and lower grooves facing each other, and inserting side guide plates (#) into these grooves (d). In this way, the width expansion of the rolled material (6) is restrained by the side guide plate (1), and the width end portion can be made rectangular. [Problem to be solved by the invention] However, such conventional In this method, the position of the groove (1) provided on the upper and lower work rolls (,) (,) is fixed, so there is a problem that it can only be applied to one type of rolled material (b). In addition, although the side guide plate (1) restrains the deformation of the rolled material (b) in the width direction, its position is fixed, so it cannot be adjusted to actively reduce the width of the rolled material (6). Furthermore, even if there was a narrow width part at 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、積極的に圧延材の偏置
形量を制御し得るようにしたものである。In view of these circumstances, the present invention is designed to actively control the eccentric shape of the rolled material.

該ガイド部材に押付装置を接続した構成としている。The rolling apparatus of the present invention has the following features on both sides of the plate rolling work roll:
A guide member is disposed so as to be in contact with the width end surface of the rolled material, and a pressing device is connected to the guide member.

〔作　　用〕[For production]

従って、圧延材の幅端面変形量が押付装置によって積極

にするとＥＤ＃Ｏとなるが、ΔＢは約０．７１１ＩＩＩ
の幅縮みとなる。First, to explain the basic theory of the present invention, a rolled material (steel plate in this case) (2) with an entry side plate thickness of 2.2 m is rolled using upper and lower work rolls (11(1)) as shown in FIGS. 12 and 15. The edge drop ED (=Maki-touge) and width widening ΔB that occur during rolling are as shown in Fig. 14 when an external force F2 is applied to the width end of the rolled material (2) in the rolling area (cross hatching part). In other words, in the state of F2=0, there is a widening of 9ΔB1 edge drop addition.Therefore, F2
For example, F7. # At 500 kg, ΔB #0, but ED still exists. F24-. 1000kIi
ED#O, but ΔB is approximately 0.711III
The width will be reduced.

影響を受け、従来のようにΔＢ＃０の圧延をしてもＥＤ

、Ｆ２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, ΔBXED is greatly affected by FZ, and even if ΔB#0 is rolled as in the past, ED
As a result, it cannot be reduced below the target value. Therefore, a rolling mill that can set F2 to an optimal value is desirable.

次に、具体的な実施例を説明する。Next, a specific example will be described.

), and each side guide plate (4) is configured to be pressed against the outer peripheral surface of the mating work roll (11) by a hydraulic cylinder (6) via a roller (5). In addition, a pressing device (7) for applying an external force (restraint force) F2 in the roll axis direction to the width end face of the rolled material (2) is installed, and a pressing device (7) is installed between the pressing device (7) and the side guide plate (4). are connected with an appropriate rondo material (8).In addition, the rondo material (
A load meter (9) is installed between the pressing device (8) and the pressing device (force) so that the external force F,!, can be detected.
As for 7), a hydraulic sill, a screw nut, a wedge mechanism, etc. can be adopted. In such a configuration, when rolling the rolled material (2), the amount of edge drop and width widening (or narrowing) )
Apply external force F7 to the pressing device (7) K and side guide plate (4) so that F7. You can do this while giving. Furthermore,
The external force F2 was controlled so that the edge drop amount of the rolled material (2) after rolling and the sheet width detector (not shown) became optimal values. It is also possible to decide on a certain F and always keep F2 at that value.

The width end of the rolled material (2) is restrained by the side guide plates (4) (4), but the side guide plates (4) (4) and the rolled material (2) are in contact at the entrance side of the rolling area. (For example, in the flat area GDDG, the side guide (41 (4)
) and the rolled material (2) are in contact with each other, but the work roll (1)
and are not in contact with the rolled material (2)). If the width of the exit side part of the rolled material (2) is narrower than the width of the input side part, the area G
Even in DDG, the rolled material (2) may be compressed in the width direction and buckling may occur.
