摘要： PURPOSE:To restrict the increase of the rolling load due to the reduction of the sheet thickness, and at the same time, to perform the shape straightening work, by successively decreasing the roll diameter along the traveling direction of the strip, and by giving the traveling strip the 3 degrees or larger feed-in angle, at rolling the strip being passed through pairs of large and small work rolls. CONSTITUTION:At rolling the strip S being passed through plural pairs of work rolls consisting of large and small work rolls 9, 10, 11, 12,..., etc., the diameter of these tandem arranged large and small work rolls 9, 10, 11, 12, etc., is successively decreased along the traveling direction of the strip S; the strip S, being given the 3 degrees or larger feed-in angle by the deflector rolls 29, 30, etc., is zigzag passed through these plural pairs of large and small work rolls; hereby, the rolling and straightening works are simultaneously performed. According to this method, even in case of requiring a high draft percentage, the rolling load can be reduced to a relatively small value, and besides, the strip with good flatness can be efficiently obtained by the rolling work.

摘要： PURPOSE:To prevent the generation of edge drops, etc. and to obtain products of good shapes by forming split type eccentric rolls for the backup rolls of multistage rolling mills and loading roll bending force upon the metal chocks of intermediate rolls. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally the axial direction of stationary shafts 5a and the bearings of the split rolls are off-centered. Crowns are adjusted by the entire part of the rolls 4. Crowned parts are provided in the end parts of upper and lower work rolls and intermediate rolls 3 and are moved symmetrically in an axial direction. Further, means 11, 12 for loading roll bending force are provided to metal chocks 7 for the intermediate rolls to transmit the rugged shapes formed by the backup rolls effectively to the work rolls 2. By such mechanism the products having less generation of edge drops, etc. are obtained.

摘要： PURPOSE:To contrive the improvement of the thickness accuracy of the sheet in the direction of the breadth to a value better than that to be obtained by the conventional method, by arranging the work rolls to bite the rolled material so as to possess a specified diameter ratio, and by specially arranging two pairs of intermediate roll including the driving roll between the small diameter work roll and the backup roll, at performing the rolling work. CONSTITUTION:At performing the rolling work by biting the rolled material S with the large diameter work roll A and the small diameter work roll (a) in diameter a half or less than that of the work roll A, and hereby, giving the rolled material S the tension and the bending force, a pair of two first intermediate rolls b1, b2, and a pair of three second intermediate rolls c1-c3 are arranged between the small diameter work roll (a) and the backup roll group d1-d4; hereupon, one of these rolls is driven to rotate, and the first intermediate rolls b1, b2, are shifted in the direction parallel to the roll shaft, and also, the second intermediate rolls c1-c3 are shifted opposite to the shifting direction of the rolls b1, b2; under this condition, the rolling work is performed. According to this method, the accuracy of sheet thickness in the direction of the breadth can be improved even in case of the very thin high tensile steel strip, depending on said respective synergistic effect.

摘要： PURPOSE:To obtain a titled apparatus that can perform strong pushing of a material to be rolled by providing pinch rolls that pinch, drive and advance the material to be rolled and guides that prevent buckling of the material to be rolled and supplying coolant to the guides. CONSTITUTION:Pinch rolls 4, 5 and guides 2, 3 are provided in the housing 6 on the stand 7, and the pinch rolls 4, 5 are driven by a fluid pressure cylinder 8 or an electric motor and the material to be rolled 1 is pinched and pushed into a rolling mill which is small and having insufficient power to bite by itself such as work rolls 12, 13 of a multistages cluster mill 11. Following above-mentioned pinch rolls 4, 5, guides 2, 3 are provided to prevent occurrence of buckling even when pushing force is made larger. The distance between inner walls of the guides 2, 3 is made as small as possible. At the same time, roll coolant 9, 10 or air is spouted from numerous holes provided on the face of inner wall to prevent buckling by reducing contact resistance with the material to be rolled 1.

摘要： PURPOSE:To remove scales effectively in a short time by giving a strip tension and bending by vertically asymmetric work rolls of different diameter before pickling the strip. CONSTITUTION:A strip S of hot rolled coil 11 enters a rolling mill 4 provided with vertically asymmetric work rolls of different diameter and subjected to tension and bending action on the upper and lower faces. This rolling mill 4 consists of a work roll 5 of small diameter backed up by backup rolls 7, 7, and a work roll 6 of large diameter provided opposite to the work roll 5. Accordingly, large bending force acts on the strip S and cracking effect on scales of surface layer is increased. Then, the strip is subjected to tension and bending action in the second rolling mill 4' equipped with vertically asymmetric work rolls of different diameter. Arrangement of a small diameter work roll 5' including back-up rolls is reverse of the first rolling mill 4. Pickling is made in a pickling tank in a state that crack generation of scales is increased by the rolling mill 4'.

摘要： PURPOSE:To eliminate a difference between the front and back sides of a strip, and to prevent generation of an L-shaped camber, etc., by reciprocally passing a strip between a central large diameter, driving work roll and small diameter cluster rolls arranged above and below the central roll, and by applying a strecth-and- bending rolling work to the strip. CONSTITUTION:A constant tension is applied to a strip S between a large diameter, driving work roll 13 and the lower multistage cluster rolls A, and a large bending is given to the strip S on the side of a small diameter work roll 7; under this condition, a stretch-and-bending rolling work is applied to the strip S. When a coil held in a coiler 1 finishes a rolling work, the rotation of all of the coiler 1, an uncoiler 25, and each roller, are reversed, and an upper mutistage cluster roll B is moved down; then, the strip S is passed between a small diameter work roll 14 and the central work roll 13 in order to bend the strip S toward the roll 13 side; under this condition, a stretch-and-bending rolling work is applied to the strip S. According to the present method, a single rolling stand can eliminate the difference between the front and back sides, and the generation of an L-shaped camber, etc., can be prevented.

摘要： PURPOSE:To reduce the size and initial costs of driving devices for the purpose of crown adjustment by using split type eccentric rolls for the backup rolls of multistage cluster rolling mills, and moving the other eccentric rolls apart from a plate material with the eccentric rolls at the center as a ference. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally with their axial direction. With the eccentric rolls 4c in the central parts among the respective eccentric rolls 4a-4e as a reference the other rolls 4a, 4b, 4d, 4e are moved so as to be moved apart from a plate material whereby their crowns are adjusted. The thickness of the plate is controlled by utilizing screw down devices, etc. By such method the driving forces for the rollers 4a-4e are decreased and equipment costs are reduced.
