摘要： PURPOSE:To maintain sheet thickness highly accurately by deciding a draft set- value basing on a mill stretch (an increment of roll gap between upper and lower roll due to a rolling load and a bending force) obtained by theory and experiment. CONSTITUTION:The causes of a mill stretch are separated into roll deformation and other factors. As the deformation characteristics of these factors are complex and difficult to resolve, a press-squeezing experiment is performed by previously touching the upper and lower rolls. From the relationship between a rolling load and a draft set-value obtained from those results, a contributory content other than roll deformation excluding the contributory content of roll deformation obtained theoretically is obtained; and a highly accurate equation of mill stretch is obtained. Thus an automatic sheet thickness control is performed basing on the equation, and the sheet thickness is maintained highly accurately.

摘要： PURPOSE:To surely control the lengthwise plate-thickness distribution and plate-crown plate shape to conform them to the desired values and to improve the quality of steel plate, by performing repective controls of the lengthwise plate-thickness distribution and the plate-crown-plate-shape independently without mutual interference, in rolling a steel plate by a plate rolling mill having a roll bending device. CONSTITUTION:An independent operating quantity S0 of a screw-down device required to conform the lengthwise plate-thickness distribution of a steel plate to the desired value and an independent operating quantity F0 of roll bending force required to conform the plate-crown plate shape to the desired value are both computed at the same time in rolling a steel plate. An operating quantity DELTAF of roll bending force to compensate the fluctuation of rolling load DELTAP caused by the S0 and the plate-crown plate shape caused by the DELTAP are computed. An operating quantity F1 of roll bending force is obtained from F0+DELTAF, and an operating quantity S1 of the screw-down device is obtained from S0+DELTAS by computing an operating quantity DELTAS of the screw-down device to compensate the fluctuation of plate thickness of steel plate caused by F1. The screw- down device and the roll bending force of the rolling mill are controlled by adopting the F1 and S1 as the real operating quantity.

摘要： PURPOSE:To reduce the edge drop in the top of the slab, and to enable the edging work to effect a large breadth reduction in the slab, by making the rolling reduction effected in a pass designated with an even numeral equal to or larger than the rolling reduction effected in the former pass designated with an odd numeral. CONSTITUTION:The edging work is carried out by VSB (vertical scale breaker) through plural passes in which the rolling reduction effected in a pass designated with an even numeral is specified to be larger than that effected in the former pass designated with an odd numeral. Therein, the pass of an even numeral in the totally five passes, for example, means the second pass and the fourth pass; whereas the pass of an odd numeral means the first, the third and the fifth passes. Thereby the former pass of an odd numeral corresponds to the first pass against the second pass and the third pass against the fourth pass. However, the large rolling reduction in the pass of an even numeral and the small rolling reduction in the pass of an odd numeral are not always effected in this manner; in the case of five passes for example, it is possible to carry out the rolling work with a uniform rolling reduction in the first to the fourth passes and a light rolling reduction in the fifth pass for obtaining a sufficient effect.

摘要： PURPOSE:To obtain a directional electrical steel plate having an excellent magnetic characteristic by rolling the steel plate with the rolls having the surface roughness changed of layers to >=2 layers of zones in the longitudinal direction of the roll body. CONSTITUTION:Rolling rolls 1, 2 are formed alternately with layers with zones G having large roughness and zones T having small roughness in the longitudinal direction of the roll body, in such a way that the zones G having large roughness on the upper work roll 1 are positioned in the zones G having large roughness on the lower work roll 2. If a hot-rolled slab S is rolled with such rolls 1, 2, the slab is difficult to elongate longitudinally in the part corresponding to the zone G having large roughness of the roll as the coefft. of friction is large in said zone. The slab elongates easily longitudinally in the part corresponding to the zone T having small roughness of the roll as the coefft. of friction is small in said part. As a result, a shearing force acts longitudinally on the material rolled near the boundaries of both zones, by which an excellent magnetic characteristic is provided.

摘要： PURPOSE:To obtain a setting method applicable for an operation where a formation of rolling units is changed in a wide range, by determining the sheet thickness at the outlet side of each pass basing on a calculating equation for obtaining a deviation of sheet thickness at the outlet side, constituted of a deviation of sheet thickness in the width direction at the time when a distribution of rolling load in the width direction is uniform and said deviation at the inlet side of a mill, in case of obtaining a prescribed sheet thickness by plural number of times of rollings. CONSTITUTION:A model equation of mechanical sheet crown (a sheet thickness distribution in the width direction, expressed by a sign C, which is realized when a load distribution in the width direction is uniform) of a four high mill equipped with a bending device and an euqation of rolling load are combined. Thus the crown C for an optional rolling schedule is calculated. A sheet crown Ch at the outlet side of the mill is estimated by a prescribed equation formed by using the crown C, a crown CH at the inlet side, a draft, a correction factor of sheet crown, and a modified-crown-genetic factor. Further, a sheet shape is estimated by a prescribed equation where an elongation-strain difference is obtained from a shape changing factor, the crowns Ch, CH, and the sheet thicknesses at the inlet and outlet sides. Inversely, the crowns C, Ch and the sheet shape are controlled by changing the rolling schedule.

摘要： PURPOSE:To reduce the breadth of the slab in a high yield, without causing the edge drop, by gradually changing the gap of the pair of vertical rolls from the point before the slab is running out of the pair of vertical rolls. CONSTITUTION:The rolling work for the slab is continued keeping constant the gap of the pair of vertical rolls at the normal size; as the rolling point approaches the bottom end of the slab, the gap of the pair of vertical rolls is widened from the point C corresponding to the initial length (1+b)lB of the slabe before undergoing the rolling work; thereafter the said gap is widened by DELTAB along a parabolic curve through a section of length lB. Therein the length lB is obtained by expressing the length LB of the breadth-reduced part at the bottom of the slab as a result of the rolling work of the horizontal roll following to the final edging pass in case when the method of this invention is not performed in terms of the length before the final edging pass; besides, DELTAB designates the breadth reduction in the bottom of the slab as a result of rolling work by the pair of horizontal rolls following to the final edging pass. The widening of the gap is stopped at the point D after the rolling work progresses as far as the length lB. The gap of the pair of vertical rolls is kept at this size, and the rolling work is continued as far as the distance obtained by multiplying the length lB by a parameter (b), and the edging pass is completed at the point E.

摘要： PURPOSE: To prevent the generation of a plane camber in a metallic sheet material when it is subjected to an edging process, by shifting a roll pair of a vertical roll stand, arranged on the runout side of a horizontal roll stand standing as the last stand in the rolling direction at that time, transversely to the lower temperature side as much as an amount corresponding to the transverse temperature difference in the metallic sheet material.
CONSTITUTION: A rolling work is applied to a metallic sheet material for reducing its breadth and thickness; for this purpose, a rolling mill line is constituted of a vertical roll stand V
1 , a horizontal roll stand H and a vertical roll stand V
2 , and the rolling work is performed in the direction of an arrow mark X. In this case, if the transverse distribution of temperature in the rolled material shows that the temperature on the driving side DS is relatively higher than the working side SW, the vertical roll pair of the stand V
2 , standing on the downstream side in the rolling direction, is shifted from a roll position shown by the dotted lines to a roll position shown by the full line, while keeping the vertical roll gap as it is, as far as a distance l to the working side WS that is the lower temperature side. As a result, any camber is not generated in the rolled material.

摘要： PURPOSE:To prevent the decline of yields owing to the necking of the strip occuring in the rolling work, by controlling the gap of the vertical roll pair for compensating the breadth of the top and bottom ends of the rolled material, and next, by theoretically controlling the gap of the vertical roll pair, in carrying out the edging work for the top and bottom ends of the strip. CONSTITUTION:The patterns A-B-C-D of the theoretical gap (opening) of the vertical roll pair in the edging stand, required in preventing the generation of the necking in the strip, is obtained from the equation I (in which, B1 is the breadth profile 1 to be mentioned below, and alpha, beta are constants determined from the rolling condition) by substituting the breadth profile 1 of the strip on the feed-in side of the edging stand and the aimed breadth of strip B2 to be obtained by the broadside rolling work following the edying work of the edging stand. Next, a gap A', which is larger by a1 than the gap of the vertical roll pair just rolling the strip in the normal state, is obtained from the position B distant by l1 from the top of the rolled material, and a gap compensating zone A'-B is set up; then, the rolling work is carried out while controlling the breadth of the top and bottom ends of the strip according to the gap pattern A'-B-C-D.
