摘要： PURPOSE:To improve the product dimensional accuracy by dividing a roll shaft into two pieces, putting them inserted into each other in a horizontal direction, installing a skew angle setting and drafting device for a horizontal roll and a roll gap setting and drafting devices for the roll shafts, respectively. CONSTITUTION:Roll shafts 2a, 2b devided into two pieces in the axial direction and are put to be inserted into each other in a horizontal direction and the roll shafts 2a, 2b are provided with spline shaft parts 6a, 6b and roll skew angle setting and drafting devices 3a, 3b, respectively. Then, roll gap setting and drafting devices are installed and brought into contact with the devided shafts 2a, 2b to roll a rolled stock 9. At that time, flange parts 9a are rolled with a roll skew angle alpha and a roll gap kept to a prescribed value by generation of a relative sliding between rolls 1a, 1b and the spline shafts 6a, 6b machined into a spherical shape. The mill rigidity is increased because of double hold rolling and the product dimensional accuracy is improved.

摘要： PURPOSE:To permit optional online setting of a roll width by fitting stationary rolls and moving rolls to both ends of an outside peripheral screw of a roll shaft and moving the moving rolls by a prescribed roll width adjusting screw and external gear. CONSTITUTION:The stationary horizontal roll 21b and the movable horizontal roll 21a are fitted onto the outside peripheral screw part 24b of the roll shaft 22 by which a lower horizontal roll 21 is formed. The roll width adjusting screw 24a screwed to the screw 24b is fitted to the inside end face of the roll 21a and the external gear 26 is meshed with the gear part 25 on the outside periphery thereof. The change of the roll width is executed by removing a prescribed stopper, meshing the gears 26, 25, rotating the gear and moving the roll 21a to change the spacing according to the above-mentioned constitution. The upper horizontal roll 20 is similarly constituted. The optional online setting of the roll width is thus made possible.

摘要： PURPOSE:To perform rolling with good efficiency by disposing a vertical rolling mill between two units of horizontal rolling mills having calibers, placing the slab upright and rolling the same. CONSTITUTION:The slab 1 drawn out from a heating furnace is rotated 90 deg. by a known means and is placed upright in such a manner that slab longer sides come to the side face, after which it is conveyed by a table not shown and is fed into the calibers 3 of horizontal rolls 2. Thence, the slab 1 is broadside reduced by the horizontal rolls 2 to become the slab 1 showing a dogbone shape having convex parts 4 on the both edges of the slab. Following to this, it is rolled square by the vertical rolls 5 having flat roll surfaces. At this time, the vertical rolls 5 are flat and therefore there is no need for moving the vertical rolls 5 in the roll axis direction. Thence, the slab 1 out from the vertical rolls 5 is further subjected to broadside reduction by the calibers 3 of the rolls 2 set in the next specified position.

摘要： PURPOSE:To freely and distinctively manufacture many size of the shaped products with economy, effect and well dimension accuracy by making the stand interval changable corresponding to the interval of the roll on the roll stands in cantilever arranged in opposite positions with interposing the pass-line of the material to be shaped. CONSTITUTION:A pair of overhang roll stands 1A, 1B providing the roll 20A-20D are set in mutually opposite, a pair of the upper side stand interval adjusting devices 11A, 11B are set at its upper side and the lower side stand interval adjusting device 6 is set at the lower side. Therefore, the interval of stands is changed corresponding to the interval of rolls. Further, by reciprocating the shift frame 3A, 3B with the shift cylinder 4A on the sole plate 2, the above roll stands 1A, 1B are shifted to the position without interfering with the material to be rolled except the passing time of the required material to be rolled.

摘要： PURPOSE:To shorten the length of a rolling line and to reduce an equipment cost in the universal rolling of a track by moving an edge rolling mill having >=3 caliber orthogonally to a rolling progressing direction, aligning each caliber with the pass line of adjacent universal rolling mills and executing rolling. CONSTITUTION:The rolling layout of a rail is composed of a rough rolling mill BD having caliber in six kinds, an intermediate universal rolling mill U1, an edge rolling mill E having three kinds of caliber and equipped with a vertical roll and a finish rolling mill F. A rolling steel is then rolled in the rough shape of the rail by the BD rolling mill. The U1 rolling mill is then made an empty pass and it is rolled by the E rolling mill CAL6 caliber. Thereafter it is reciprocated between the U1 rolling mill and E rolling mill, rolled by the F rolling mill after its rolling of five passes and becomes a product. At this time, each caliber is aligned with the pass line of the adjacent universal rolling mills U1 in order to CAL6 CAL4E CAL2E with the rapid movement of the E rolling mill orthogonally with the rolling direction according to the progress of the rolling pass and the rolling steel is rolled.

摘要： PURPOSE:The captioned position adjusting device which is improved of its workability with a simple mechanism by moving and adjusting roll assemblies by the liquid pressure cylinder devices fixedly mounted to the yokes constituting the slide parts supporting said assemblies. CONSTITUTION:A vertical roll 5 having a caliber 4 constitutes a roll assembly 3 together with a pair of chocks 6, 6 supporting this and this assembly 3 is assembled and supported slidably in the roll axis direction to a yoke 7. A liquid pressure cylinder device 14 is fixedly mounted to the yoke 7 and said yoke 7 is made adjustable of its roll radial direction position by a screw-down mechanism 10. The position of the piston 15 of the liquid pressure cylinder device 14 is detected by a position detector 18 and pressure fluid is fed into the cylinder 17 or 17' through the control system of the liquid pressure cylinder device, whereby the roll assembly 3 is vertically adjusted. Thereby, the relative position of the roll caliber 4 with respective to the horizontal table 2 is adjusted most adequately.

摘要： PURPOSE:To prevent generation of rattle in the direction of the rolling line, by holding the arm of the housing of the horizontal mill train combined with the vertical mill train, between transverse frames of respective upper and lower housings of the vertical mill train, and by locking the locking head of the arm on the locking step of the transverse frame. CONSTITUTION:The vertical rolling mills V1, V2 possessing vertical rolls 11, 12 for performing the edging of the slab S, and the horizontal rolling mill H possenssing the horizontal roll 2, are arranged in the order of V1, H, V2. The arm 11 of the housing 10 of the horizontal rolling mill H is inserted into the opening formed between upper and lower housings 3, 4 of the vertical rolling mill, and the locking head 11' of the arm 11 is locked on the locking steps 8', 9' of the transverse arms 8, 9; hereby, these parts are combined. Next, wedges 12, 13 are driven into the gap between the transverse frames 8, 9 and the housing 10, in order to rigidly tie the housing 10 with upper and lower housings 3, 4 into one body. By tying only the lower housing 4 to the sole plate 5, the setting work of the mill train is finished. According to this method, the sufficient rigidity can be held, and also, the distance between the vertical roll and the horizontal roll can be shortened.
