摘要： PURPOSE:To prevent the variation of the dimensions of a strip in its width direction and the generation of flaws at the ends of the strip, by preventing the vertical movement, etc. of the strip between vertical rolls by slanting them, in rolling a strip in its width direction by a vertical mill. CONSTITUTION:In edging a strip 2 by a pair of vertical rolls 5a, 5b; the strip 2 becomes sometimes unstable and moves upward and downward between both rolls 5a, 5b, which changes the dimensions of strip in its width direction and generates flaws at both ends of the strip in the same direction. For preventing them; when the strip 2 moves one-sidedly upward between both rolls 5a, 5b, the extent of the movement is detected by a vertical movement detector 8 of the strip 2, and its result S1 is inputted to a slanting angle operator 9 to operate a slanting angle of the vertical roll. The operated result S2 is inputted to a slant controlling device 10, which drives a vertical roll slanting device 7a (7b) basing on slanting signals S3, S4 to slant the vertical roll, tereby preventing the unstable upward and downward movements of the strip between both of the rolls 5a, 5b.

摘要： PURPOSE:To reduce the edge drop and crown of a sheet and to improve the accuracy of its width by subjecting a hot strip to high and low rolling reductions in the width directions at the front and rear stage sides of a mill and applying tensions to the strip respectively. CONSTITUTION:A hot strip S1 is subjected to high rolling reduction in its width direction by a vertical rolling stand 2 placed at the front stage side, in a state of making the peripheral speed of a work roll 31 of the 1st stand 11 lower than that of a work roll 32 of the 2nd stand 12 and enhancing the tension of strip S1. In this way, the buckling strength of hot strip S1 is enhanced, and the rolling reduction in its width reduction is increased to 2-3 times a conventional one. Therefore, the sheet crown control is easily performed, and the adjusting amount of final sheet-width is enlarged. Further, the tension of hot strip S2 is increased by making the peripheral speed of a work roll 37 of stand 17 larger than that of a work roll 36 of stand 16, and the strip S2 is properly subjected to rolling reduction in its width direction by a vertical rolling stand 22 at the rear stage side. At that time, the buckling strength of strip S2 is improved, and the width rolling reduction can be performed. Accordingly, the edge drop and crown of a sheet is remarkably reduced, and the accuracy of the width of product is improved.

摘要： PURPOSE:To directly detect roughness of a surface of a pressure roll and to sense degree of a local surface roughening, wear by providing surface roughness measuring unit to be scanned on the surface of the roll in an axial direction near at the roll. CONSTITUTION:A noncontact type surface roughness measuring unit 2 having a semiconductor laser is provided at a position near a pressure roll 1, and guided via a guide rail 4. A surface of the roll 1 is always monitored by a camera 3 from a position separate from the roll 1 during rolling or between rollings, and when a malfunction is discovered on the surface of the roll, the unit 2 is moved to a malfunction position. The position is scanned by the unit 2 to detect surface roughness of the roll 1. A roll surface grade of the roll 1 is altered according to roll surface roughness. Since a flaw grade of a steel plate is altered by a variation in the roll surface grade, the roll 1 is recombined in response to the surface roughening state of the surface of the roll to stabilize quality of a product. The unit 2 is always scanned, and the surface roughness of the roll 11 may be detected.

摘要： PURPOSE:To cross roll a strip without buckling the same in the stage of cross rolling a strip by providing an edger consisting of a vertical rolling mill between rolling stands for the strip by adjusting the height and inclination of the vertical rolls of the vertical rolling mill by the movement of a looper. CONSTITUTION:A vertical rolling mill 5 for cross rolling of a strip 4 and a looper 7 are installed between rolling stands 3 and 3' for rolling the strip 4. The position and angle where and at which the strip 4 contacts with the vertical rolls 8 of the mill 5 change with the fluctuation in the position of a looper roll 6 of the looper 7 in the stage of passing the strip through the mill 5 while applying proper tension thereon by moving upward or downward the roll 6. A cylinder for adjusting upper and lower positions and a cylinder for tilting are therefore attached to the rolls 8, and are so adjusted that the strip 4 is prevented from deviating from the rolls 8 and that the axial line of the rolls 8 is at a right angle to the end face of the strip. The strip 4 is thus stably cross rolled without being buckled.

摘要： PURPOSE:To perform a width rolling reduction with the optimum rolling reduction force, to increase the plate width accuracy and to improve the edge drop by fitting a small diameter cylinder into the large diameter cylinder movable in the width direction of a rolling stock and by selecting the cylinder according to the plate thickness. CONSTITUTION:A vertical roll 4 is moved in the direction apart from the large diameter cylinder chamber 11 which is supported with the stroke adjustably, when a pressure liquid is fed to the anti-vertical roll side inside the large diameter cylinder chamber 11. Now the vertical roll 4 fitted to the supporting part at the tip is advanced at high speed. In case of the rolling stock being a thick one, the rolling reduction is started with its contact with the width end of the rolling stock by advancing as it is. In case of a thin one on the other hand, a large diameter piston 13 is stopped prior to the vertical roll 4 coming into contact with the rolling stock and the rolling reduction with small rolling reduction force and the contact with the rolling stock thereafter is performed by advancing the small diameter piston 13. In this case the vertical roll 4 is inclined by turning the worm wheel 9 which is linked by a key 15 to the outer periphery of the small diameter cylinder chamber 11 by driving a worm 12 by driving the motor in an inclining mechanism 6, in case of the rolling stock having a certain angle for the level.
