摘要： PURPOSE:To execute always stable rolling regardless of the width of a flat steel without changing particularly horizontal rolls by sliding sleeve rolls constituting the horizontal rolls in the transverse direction thereof to adjust the gap between the sleeve rolls to an adequate gap and subjecting the flat steel to intermediate rolling. CONSTITUTION:The sleeve rolls 7 are respectively slid in the transverse direction in conformity with the width, thickness, etc. of a slab 5 subjected to rough rolling until the sleeves are set in the adequate position, then the slab is subjected to the intermediate rolling in a universal mill. The slab 5 rolled by a universal rolling mill 1 in such a manner has an unrolled down part but the slab 5 is thoroughly flattened in succession thereto in a duplex rolling mill 2 where the slab is thoroughly flattened by the horizontal rolls 6 thereof. More specifically, the rolling mill 1 and the rolling mill 2 for edging, etc. are continuously disposed generally in a production line for an H-beam and the mill 2 shown in the figure is straightly usable as the edging mill for this purpose. The change of the horizontal rolls according to the flat plates having difference widths and thickness is not required and the continuous and stable rolling is made possible even with said flat plate according to the above-mentioned method.

摘要： PURPOSE:To enable exact control and to obtain a rolling plate having a desired shape without deformation by measuring the width distribution of the rolling plate on the inlet side of an edger roll and calculating the set quantity of the edger gap by using the measured value. CONSTITUTION:A width gage 4 is provided on the inlet side of the edger roll 1 adjacently to said roll 1 and the width of the rolling plate 3 prior to the entry to the roll 1 is measured. The width distribution W0(X) (X: the distance from the front end of the plate) of the plate 3 is thus determined. The distribution W0 is stored as a width deviation distribution DELTAW0(X) in a width fluctuation memory 5 and is supplied with a time lag to a computer 7 by a time lag device 6. On the other hand, the pass schedule 8 determined preliminarily by an upper computer, etc. and the target width DELTAW3(X)9 required in the outlet of the rolling mill are inputted to the computer 7 and the optimum set distribution DELTAW1(X) of the edger gap to obtain the target width is calculated by the computer 7. Such quantity is fed forward to an edger gap setter 10, by which the edger gap is controlled.

摘要： PURPOSE:To correct surely the curving of a rolled material which curves at a large pitch along the longitudinal direction thereof by providing vertical rolls on the outlet side of a roughing mill and pressing and bending the front and rear ends of the rolled material in the transverse direction of the material. CONSTITUTION:A pair of vertical rolls 31 which are symmetrical with respect to the centerline 10 of a rolling line or two pairs of vertical rolls which are zigzag are provided on the outlet side of a roughing mill 1. A detector 33 which detects the camber curving at a large pitch along the longitudinal direction of a rolled material and a speed detector 34 are provided on the outlet side of the mill 1. The positions of the rolls 31 are adjusted according to the direction and amt. of the camber as well as the speed of the material 20. After the roll 31 contacts with the end of the material 20, said roll 31 is moved in a correcting direction. The camber is thus surely corrected in a way as to have no adverse influence.

摘要： PURPOSE:To eliminate the need for trimming a width variation part, and to improve product yield, by calculating an optimum width rolling reduction basing on the informations of a slab width, and obtaining the uniform width of the slab at a coil stage after rough rolling by rolling the slab basing on the calculated results. CONSTITUTION:The width in the longitudinal direction of a slab 1 having width variation produced in the front stage of hot rolling is measured by a width measuring part 2. The width information required for hot rolling is calculated from the measured results, and optimum width rolling reduction is decided by the information basing on the extent of width variation allowable as a product. And the optimum rolling reductions of respective roughing mills 10, 11 are set and instructed basing on the optimum width rolling reduction. Thus the slab 1 is rolled to the allowable width by a vertical scale breaker 9 having a caliber and the mills 10, 11, basing on the instructions.

摘要： PURPOSE:To improve the accuracy in the estimation of the transverse return extent in a horizontal rolling stand and to control the broadside size of a rolled plate adequately by detecting the height and position of a dogbone right after broadside rolling with an edger in the stage of producing a steel plate by hot rolling. CONSTITUTION:A steel plate is rolled down broadside with the edger rolls 2, 2 of an edger 1 in the stage of hot rolling the steel plate with a rolling mill consisting of the edger and the horizontal rolling stand. The height of the dogbone of a rolled material 3 in this case is measured in difference from the central part with the load cells 6b, and 6a of a roll 4b in contact with the dogbone and a roll 4a in contact with the central part. The position in the highest part of the dogbone is measured by measuring the pressure to be exerted on both ends of the roll 4b in contact with the dogbone with strain gages 8a, 8b, and the transverse return extent in the next horizontal rolling mill is estimated with high accuracy from both measured values, so that the broadside size of the rolled plate is controlled to a target size.

摘要： PURPOSE:To control the final breadth of a rolled steel sheet exactly to an aimed size, in case of rolling a steel sheet with the first rolling stand providing a horizontal roll and the second rolling stand providing a vertical roll and a horizontal roll, by adjusting the roll gap of the vertical roll of the second rolling stand correspondingly to the dog-bone height of the steel sheet on the run-out side of the first rolling stand. CONSTITUTION:A continuously cast billet 4 is rolled into a steel sheet by the first rolling stand 100 providing a final horizontal rol1 101 and the second rolling stand providing a vertical roll 102 and a horizontal roll 103. The radio, between the thickness at a position of a dog-bone 2' and the thickness H at the middle of the rolled steel sheet 4 on the run-out side of the final horizontal roll 101 of the first rolling stand, has a prescribed relation with the breadth of the steel sheet on the run-out side of the vetical roll 102 of the second rolling stand and the sheet breadth increased as a result of eliminating the dog-bone on the run-out side of the horizontal roll 103 of the second rolling stand; according to the actual measurements of the said thickness radio and breadths, the roll gap of the vertical roll 102 of the second rolling stand is adjusted so as to control the breadth of the rolled steel sheet on the run-out side of the horizontal roll 103 of the second rolling stand exactly to the aimed size.

摘要： PURPOSE:To rolling mill line for billet, bar, wire, etc., which performs a high drawing capability given by controlling the rolling rate of rolling mill line to less than strip limit determined by a relation between rolling rate and contact angle. CONSTITUTION:The aperture between each roll is set so that the first stand 11 has the contact angle mu and the second stand 21 has the contact angle >=tan mu. The third stand 31 is a pivot stand, when the steel to be rolled cuts into the first stand 11, a steady-state current is detected by the detector 12 and then is memorized by the memory 13. And, when the steel to be rolled cuts into the second stand 21 and the certain current value is reached, the current value is detected and then compared with a current value previously memorized to control the roll rotation number of the first stand 11 and to produce a non-tension and non-compression state. The same control is made for between the stands 21 and 31. The use of this system enables one to reduce the number of rolling mills and thus to perform high efficiency rolling.
