Description of the Invention (1) (Technical Field) The present invention relates to a rolling machine and a rolling method for rolled strips of rolled metal. In particular, the present invention relates to a rolling mill and a rolling method which are suitable for obtaining a convex surface of a plate roll and a strip having an excellent plate shape. (Background Art) A four-stage rolling mill or a six-stage rolling mill disclosed in Japanese Patent Application Laid-Open No. Sho 5 6-6 6 3 0 7 is shown in FIG. 7. There is a problem of improving the work roll diameter reduction or roll convexity control ability. Further, as the ten-segment multi-roll type rolling mill with reduced diameter work rolls, there are, for example, Japanese Unexamined Patent Publication No. 3 9-1 8 2 3 8 and Japanese Unexamined Patent Publication No. 11-2 7 7 107. In the ten-segment multi-roller rolling mills described in these publications, the roll support mechanism or the rolling load and the actual machine have not been fully considered. If a large rolling load is applied, the bearing portion becomes large, or the surface is convex. There is also a problem of realizing the control ability. An object of the present invention is to provide a rolling mill and a rolling method which use a small-diameter work roll and have excellent control capability of the convexity of a plate roll. (Summary of the invention) A rolling mill having a pair of work rolls above and below a rolled strip and supporting the work. Two pairs of intermediate rolls above and below the roll, and two pairs of reinforcing rolls above and below each of the intermediate rolls, or A rolling mill equipped with a pair of work rolls above and below a rolled strip and supporting two pairs of reinforcing rolls above and below each of the work rolls. ----: ------ Line (Please read the precautions on the back before filling this page) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) -4- 476676 Ministry of Economic Affairs Printed by the Intellectual Property Bureau employee consumer cooperative A7 B7 V. Description of the invention (2) The center of the plate width is located at the end of the point-symmetrical roll 胴 The roll shoulder to reduce the L roll diameter of the car is set separately, or a bearing is provided on each reinforcing roll , Can improve the work roll diameter reduction or roll convex surface control ability. (The best form for carrying out the invention) In a rolling mill equipped with a pair of work rolls, two pairs of intermediate rolls, and two pairs of reinforcing rolls, the upper and lower pairs of intermediate rolls can be firmly and sufficiently secured from the right and left sides. Supports the next pair of work rolls above the rolled strip. With this support, the deflection of the work roll caused by the driving tangential force of the other drive rolls can be suppressed as small as possible. On the other hand, by setting the shoulders of the two pairs of intermediate rollers separately, by moving in the direction of the roller axis, it is possible to almost avoid the work rolls outside the width of the belt with a plate on one side of the shoulders and the reinforcement adjacent to the work roll The contact surface pressure between the rollers. Therefore, the bending of the upper and lower work rolls can be made to be approximately parallel with respect to the center point of the width of the strip. In this state, the bending function of the force and the bending function of the torque are effectively applied to the two shaft ends of the upper and lower pair of work rolls and the above-mentioned two pairs of intermediate rolls. Therefore, the bending of the work roll can be changed freely, and even if various defective shapes occur in the plate, it can be frequently rolled into a flat plate shape, thereby obtaining a strip plate having an excellent plate shape. A roll shoulder is provided on a pair of work rolls. By moving the work rolls in the direction of the roll axis, the bending of the upper and lower work rolls can be parallel to the center of the strip width of the strip. In this way, the bending function of the force and moment of the two axial ends of the upper and lower pair of work rolls and the two pairs of intermediate rolls is more effective. -------- ^ --------- (Please read the precautions on the back #v to fill out this page first) This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) ) -5- 476676 A7 ___B7 V. Description of the invention (3) In addition, the roller L machine composed of a pair of upper and lower working rollers and two pairs of reinforcing rollers is a work roller that is firmly secured from the right and left sides by the two pairs of reinforcing rollers. Ground support, and the bending of the small-diameter work roll caused by the driving tangential force of other driving rollers is suppressed as small as possible. In this state, the operation of the two pairs of reinforcing rollers and the reinforcing roller bearings on the driving side are combined by a plurality of hydraulic cylinders, so that the upper and lower work rolls cross each other on a horizontal plane and by controlling the interval between the work rolls, it becomes Effective plate thickness control and plate rolling light convexity control, that is, plate shape control, can be implemented. Moreover, by moving the work roll having a pair of roll shoulders in the axial direction, it is possible to achieve more effective control of the convexity of the plate roll, that is, the shape control of the plate. Hereinafter, embodiments of the present invention will be described with reference to the drawings. (First Embodiment) A first embodiment of the present invention will be described with reference to Figs. 1 to 3. The rolling mill of this embodiment is a ten-segment rolling mill including a pair of upper and lower work rolls, two upper and lower intermediate rolls, and two upper and lower reinforcing rolls, as shown in Figs. 1 and 2. 1 series above and next pair of work rolls 2, 3 are rolled. The upper work roll 2 is in contact with and supported by the left and right intermediate rolls 4, 6 on the upper side, and the intermediate rolls 4, 6 are in contact with and supported by the reinforcing rolls 8, 10 respectively. The reinforcing rolls 8, 10 are rotatably Supported in bearings and reinforced roller bearing boxes 1 8 a and b respectively. Since a reinforcing roller bearing box is provided on each reinforcing roller, it becomes possible to install a rolling load device or a course adjusting device separately.

Description of the invention (4), the direction of the rolling load from the rolling load device can be set appropriately. (Please read the precautions on the back before filling this page.) The reinforced roller bearing box 18a, b is supported by the worm gear jacks 20a, b, etc. on the housings 23a, b. Here, a load cell (not shown) may be installed in the route adjustment devices 20 a and b to measure the rolling load. The upper work roll 2 is rotatably supported by the work roll bearing boxes 2 7 a, b, c, and d. Since a work roll bearing is provided on each work roll, a bending force can be easily applied to the work roll, or an axial movement can be performed on each work roll. The upper intermediate rollers 4 and 6 are rotatably supported by the intermediate roller bearing boxes 2 5 a, b, c, and d, respectively. Since an intermediate roller bearing is provided for each intermediate roller, a bending force is easily imparted to the intermediate roller, or it becomes possible to perform an axial movement of each intermediate roller. The lower work roll 3 is in contact with and supported by the left and right intermediate rolls 5, 7 on the lower side, and the intermediate rolls 5, 7 are in contact with and supported by the reinforcing rolls 9, 11 respectively. The reinforcing rollers 9, 11 are rotatably supported by a bearing and a reinforcing roller bearing box 19a'b, respectively. The reinforced roller bearing box 19a, b is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and is supported on the casing 2 3a, b via hydraulic cylinders 2a, b. The hydraulic cylinders 2 1 a and b are only on the right side or the left side, and the remaining ones can be used as route adjustment devices such as a worm wheel jack in the same manner as the upper side. The lower work roll 3 is rotatably supported by the work roll bearing box 2 · 8 a, b, c, d, and the lower middle rolls 5 and 7 are rotatably supported by the intermediate roll bearing box 3 0 a , B, c, d. In this example, the roll load is a hydraulic cylinder with a roll milk load device. The paper size is applicable to the Chinese National Standard (CNS) A4 (210 X 297 mm). Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. 476676 A7 ________ B7 V. Description of the invention (5) 2 1 a, b. The direction of the rolling load applied by the rolling load device is different from the normal vertical direction, but is given from the direction inclined to the vertical direction. For example, as shown in Fig. 1, the direction of the rolling load applied from the rolling load device to the reinforcing roller bearing box is from the reinforcing roller 9 to the work roller 3 through the intermediate roller 5. Contains horizontal components. The horizontal component can also reduce the deflection of the work roll. Furthermore, a reinforcing roller bearing box is provided for each reinforcing roller, and since a rolling load is applied in the above-mentioned direction, a large rolling load can be applied. That is, for example, a reinforcing roller bearing box that integrally supports two reinforcing rollers on the lower side is provided. When a rolling load is applied vertically, the rolling load direction applied from the rolling load device to the reinforcing roller is in the middle from the reinforcing roller. The rolling load transmission direction is different when the roller is driven to the work roll. When large rolling load is to be applied, it must be a high-rigidity and strong reinforced roller bearing box and become large. With regard to this, in this embodiment, since there are two reinforcing rollers on the lower side. Supporting reinforcing roller bearing boxes are separately provided, and a rolling load is applied in a direction inclined in the vertical direction. The direction of the rolling load and the direction of the rolling load transmission from the reinforcing roller to the work roller via the intermediate roller are approximately the same. Therefore, even when a large rolling load is applied, the size of the reinforcing roller bearing box can be reduced. Also, if the two reinforcing rollers on the upper or lower side are integrally supported, or the roller groups on the upper or lower side are integrally supported, it is difficult to appropriately follow the change of the roll_diameter. That is, by rolling, the diameter of the roll is usually changed due to wear or honing to improve surface properties. In the case of a body-type supporting mechanism of a plurality of rolls, it is impossible to cope with a case where the diameter of each of the rolls is changed. For this paper size, the Chinese National Standard (CNS) A4 specification (210 X 297 public love) is applicable. -8- --- L -------- · Packing --------- Order-- ------- Line m?

Description of Invention (6) This, as in this example, Since a bearing box is provided for each roll, and a pressing device (route adjustment device or rolling load device) is provided for each reinforcing roller bearing box, even if the diameter of each roll is changed, the pressing is adjusted by each The device can also easily cope. In addition, when the two reinforcing rolls on the upper side or the lower side are integrally supported, or the upper or lower roll groups are integrally supported, it is difficult to replace individual rolls. To this end, in this embodiment, since the bearing supports each roll, it is easy to replace individual rolls. The rolling torque is transmitted to the work rolls 2, 3 or the intermediate rolls 4, 6 through a spindle (not shown). The intermediate rolls 4, 5, 6, and 7 are respectively paired up and down for left and right, or paired for left and right, respectively, and have reductions in the positions of the ends of the rolls which are point-symmetrical with respect to the plate width center of the above-mentioned strip 1 Roller shoulder.

The work rolls 2'3 are connected to the casing 23a'b by the hydraulic cylinders 24a, b, c, d, 31a, b, c, and d through the bearing boxes 27a, b, c, d, 28a, and b. , C, d impart bending of moment and / or force. In the following, the idea of the rolling method of the present embodiment for controlling the shape of the sheet to be rolled using the ten-stage rolling mill will be described. The cylinder push-out output of the cylinders 24c 'and 24d shown in FIG. 4 is taken as Fa, the output of the cylinder 24a and 24b is taken as fb, and the pull-out output of each of these cylinders is respectively taken as Fd, Fc. Assigning the outputs F a to F d to the work rolls 2, 3 and / or the intermediate rolls 4, 5, 6, and 7 to increase the bending force in the direction shown in Fig. 8 (a), then The strip plate 1 has a tendency to be rolled into an intermediate extension. On the other hand, when the outputs F a to F d are given a reduced bending force in the direction shown in FIG. 8 (b), the belt 1 tends to be stretched by the rolled ends. In addition, if the positions of the roll shoulders of the intermediate rolls 4, 5, 6, 7 are moved in the direction of the width of the strip plate 1, the strip plate 1 is rolled to a moderate extension trend; toward the strip plate 1 When the plate is moved in the width direction, the strip plate 1 tends to be rolled to the end to extend.

Description of the invention (8) The arm simply supports the beam, then the following formula (1 ). v = FL3 (1-3x / 2L + x3 / 2L3) / 3EI ......... (1) where v is the bending of the work roll, F is the bending force, E is the elastic constant, I Is the secondary moment of the profile, and X is the dimension defined in Figure 6. On the other hand, the bending of the upper work roll 2 according to the moment imparting function is assumed to be a cantilever simply supporting the beam, which is expressed by the following formula. v = -M (x-L) 2 / 2EI ......... (2) where Μ is the moment. Therefore, when the bending force F and the moment M are applied simultaneously, the addition of the formula (1) and the formula (2) becomes the bending of the upper work roll 2. Here, the magnitudes of these bending forces F and moments M are appropriately adjusted, and the bending of the work roll 2 is obtained as shown in Fig. 6 (a) due to the difference between the powers of the formulas (1) and (2). At this time, using the cylinders 24a, b, c, and d shown in FIG. 4 and the pull-out outputs F a to F d, as shown in the following formula for selective use, as shown in FIG. 6 (b) As shown in the figure, a roll bend such as the roll bend shown in FIG. 6 (a) is obtained. F = F d-F b ......... (3) Μ = 5 · F b ......... (4) In the formula, 5 means cylinder 2 4 a and cylinder 2 4b size. The cylinders 24a, b, c, and d are pressed and pulled to output Fa ~. Fd is applied to the work rolls 2, 3 to become bending forces F and moments M and the like shown in the direction of Fig. 8 (c), then The plate shape of the strip plate 1 is lightly rolled into an M-shaped stretched shape.

When the work rolls 2, 3 are smaller in diameter than the intermediate rolls 4, 5, the intermediate roll 4 is shown in Fig. 7 (a), 6 Compared with the distance L 1 between the peaks of bending of the upper work roll 2 to which the bending force F and the moment M are applied, it is shown in Fig. 7 (b) that the upper work roll 2 to which the bending force F and the moment are given the bending force F and the moment The distance L 2 between the peaks and bends of the bend 2 becomes larger. In the rolling method of this embodiment according to the above idea, the driving cylinders 24, 283, 乜, (:, (1 and the cylinders 26, 293, 13, and ( :, D, each roll is moved to make the intermediate roll 4 The positions of the roll shoulders of 5, 6, and 7 are consistent with the vicinity of the wide end of the strip 1. In this state, the bending of the work rolls 2, 3 is almost parallel to the strip center because of point symmetry, so they are rolled. It is formed into a substantially flat strip plate 1. Furthermore, at both ends of the work rolls 2, 3 and the intermediate rolls 4, 5, 6, and 7, a roller is used to impart a moment M and a bending force F in opposite directions to each other.

The center of the strip 1 becomes point-symmetrical and approximately parallel. On the other hand, as a comparative example, the conventional four-stage rolling mill is the same as the fifth paper size, and the Chinese National Standard (CNS) A4 specification (210 X 297 mm) is applied. -12- 丨 丨 一 -------- # 装 --------- Order --------- line · (Please read the precautions on the back before filling this page) 476676 Α7 Β7 V. Invention Explanation (10) (C) As shown in the figure, with the work roll 4 2 '4 3 and the reinforcing roll 4 4 (please read the note on the back? Matters before filling out this page) 4 5 line pressure distribution s 3' The contact surface pressure between the work rolls 42, 43 and the reinforcing rolls 44 '45 occurs outside the plate width of the strip plate 1. The bend Tu 3 of the work roll 4 2 and the bend Td 3 of the lower work roll 4 3 become a dot chain line. As shown, the plate thickness of the plate end portion of the strip plate 1 decreases drastically. As described above, in this embodiment, since the positions of the roll shoulders of the intermediate rolls 4, 5, 6, and 7 are consistent with the vicinity of the width end of each strip plate 1, the width of the strip plate 1 The contact surface between the work rolls 2 ′ 3 and the intermediate rolls 4, 5, 6, 7 has almost no pressure on one side, and the bending system of the work rolls 2 and 3 is point-symmetrically approximately parallel to the center of the belt plate 1. As a result, since the moment M and the bending force F are effectively applied to the work rolls 2, 3, the bending of the work rolls 2, 3 can be changed freely, and the work rolls 2, 3 of a small diameter are used for the rolling of high-hard materials At this time, even if various plate shape defects occur in the strip plate 1 by the convex surface of the base material and the thermal convex surface according to the thermal expansion of the roll, the strip plate 1 can be freely controlled to have a plate shape of intermediate elongation, end elongation, and compound elongation. Often it can be corrected to roll into the desired plate shape. From the above, a strip plate 1 having an excellent plate shape can be obtained. In addition to the work rolls 2 and 3, the intermediate rolls 4, 5, and 6, printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 7 also impart moments M and bending forces F, so they have a wide range of plate shapes that can be controlled. . Further, in the rolling mill of this embodiment, since the work roll can be made smaller and the roll convexity control ability can be improved, a significant effect can be expected especially for the rolling of a hard material. If the rolling mill of this embodiment is arranged in front of the tandem rolling mill, a significant effect can be expected. -13- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 476676 A7 B7 V.

Description of the invention (16) (Please read the precautions on the back before filling this page) The following indicates the board Method for controlling roll convexity (plate shape control). First, the right operating hydraulic cylinder 3 3 a is pulled from the initial position, and the upper right driving hydraulic cylinder 3 3 b is pushed from the initial position, while the upper left operating hydraulic cylinder 3 is pushed from the initial position. 3 c, and pull up the left drive side hydraulic cylinder 3 3 d from the initial position 3 1, the upper reinforcing rollers 8 and 10 are inclined with the action of each of the hydraulic cylinders 3 3, and the upper work roller 2 is on the horizontal plane The inside is inclined to the board width direction. In addition, by pushing down the right operating hydraulic cylinder 2 1 a from the initial position, the right driving hydraulic cylinder 2 1 b is pulled down from the initial position, and at the same time, the left operating hydraulic cylinder is pulled down from the initial position. 2 1 c, while pushing the hydraulic cylinder 2 1 d on the driving side from the initial position, the lower reinforcing roller 9, 1 1 is inclined with the action of each of the hydraulic cylinders 21, and the lower work roller 3 is horizontal. The plate width direction is formed to be inclined in the opposite direction to the upper work roll 2. That is, the upper and lower work rolls 2 and 3 become the milk rolls crossing each other. By the roll crossing of the work rolls, the gap between the work rolls is made geometrically larger at the end of the plate width than at the center of the plate width, and becomes the convex surface of the concave plate roll (the middle elongated shape). Therefore, the rolled convex surface (plate shape) is detected by a roll convex meter (shape detector) not shown, and the hydraulic cylinders 21 are operated with this detection. System 3 3 enables plate roll convexity control (plate shape control). According to this embodiment, since each of the two reinforcing rollers 8, 10, 9, 11 is subjected to the thrust generated by the roll crossing, a large roll crossing can be applied. In this way, the ability to control the convexity (plate shape control) of the plate-crossing rollers becomes greater. Furthermore, by using a bending function that applies a large amount or / and a moment, even a more complicated shape defect can be corrected. At the same time, plate thickness control and plate roll control (plate shape control) are implemented at the same time. -19- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) 476676 A7 B7 V. Description of the invention (17) (Please First read the precautions on the back side and then fill out this page). When controlling the plate thickness control with a sufficiently fast control cycle for the control cycle of the convex control (plate shape control) of the plate roll, there is no interference between the two. Rolled into a plate thickness accuracy, plate roll convex surface accuracy (plate shape accuracy) are excellent products. Since the control capability of the convex surface of the plate roll is relatively large in this embodiment, by arranging in the front stand of a cold tandem rolling mill with a thicker plate thickness and a larger demand for changing the convex surface of the plate roll, the accuracy of the convex surface of the rollable plate roll is more improved. Excellent product. The same roll crossing method may be applied to the first to third embodiments. As described above, according to the present invention, it is often possible to roll into a flat plate roll convex surface and a plate shape, whereby a strip plate having an excellent plate roll convex surface and plate shape can be obtained. (Industrial Applicability) In the field of rolling, a rolling mill and a rolling method can be provided which can obtain a plate roll with excellent controllability of a roll even by using a small-diameter work roll.
