摘要： PURPOSE:To enable a highly accurate drum finish with ease by adjusting material and thickness of an underlay of a rubber-wrapped roll so that the value of a circulation torque is held within a specified range detecting the torque between the rubber-wrapped roll and an impression cylinder or a plate cylinder. CONSTITUTION:In an offset press wherein a rubber-wrapped roll 10 wrapped with a blanket 3 made of rubber or the like on the circumference of an underlay 2 made of resin or the like about 0.1mm. thick put on a steel roll core 1 is brought into contact with a steel plate cylinder 11 or impression cylinder 12 under a specified nip pressure, a gear 24 is mounted on a shaft 22 of a rubber- wrapped roll 20 through a roll bearing 23 and is meshed with a gear 26 fixed on a shaft 25 of mating roll 21. A load cell 27 is mounted between the gear 24 and the roll end face of the rubber-wrapped roll 21 and a rotating force is transmitted to the rubber wrapped roll 21 from the gear 24. Then, material and the thickness of the underlay 2 of the rubber-wrapped roll 21 are adjusted so that the torque value detected with the load cell 27 is held within a specified range.

摘要： PURPOSE:To improve a leveler performance by constituting a titled leveler so that a diameter of a roll of the utmost end part of a tilting rolling reduction type roller leveler becomes larger than other roll by specified %. CONSTITUTION:A diameter of the utmost end part rolls A, B of a roll train is made larger by 0.1-3.5% than that of other rolls C, D. Accordingly, even if a plate is made to pass through from a direction of A or B, a circumferential speed of the first rolls A, B of the entry always becomes larger than a circumferential speed of the second rolls C, D, and a speed difference caused by a curvature difference of the first and the second rolls of the entry can be corrected. A roll torque also becomes a torque for driving the plate from the roll by the first - the third rolls, etc. of the entry, and its size also becomes smaller than the case of a diameter of the comventional same roll. The leveler performance is improved by this mechanism.

摘要： PURPOSE:To decrease the camber at the preceding end of a rolled material by rolling with dissimilar diameter rolls by lubricating highly the corresponding part on the outside of the rolled material where the camber is generated by the rolling with dissimilar diameter rolls. CONSTITUTION:There is a tendency toward cambering of the top of a rolled material at high curvature in rolling with dissimilar diameter rolls using an upper work roll 2 of a small diameter and a lower work roll 3 of a large diaeeter. The surface in the top part corresponding to the outside of the camber of the material 1 prior to rolling is lubricated selectively so as to be lubricated more highly than the other surface. The surface roughness of the roll 2 in such rolling mill is set larger than the surface roughness of the roll 2, and the camber at the preceding end of the material 1 is prevented by the difference in roughness and the same is further compensated with the difference in the lubrication on both surfaces of the rolled material.

摘要： PURPOSE:To provide a titled rolling mill which permits easy and quick changing of intermediate rolls by the construction wherein inner chocks which support a pair of intermediate rolls are connected with elastic devices and are moved horizontally to maintain a specified distance in the stage of releasing. CONSTITUTION:In multistage cluster rolling mills wherein a pair of upper and lower work rolls 2, a pair of upper and lower intermediate rolls 3 supporting said rolls, and plural pieces of backup rolls 4 consisting of split type eccentric rolls supporting said rolls are incorporated into housing 10, the rolls 3 are supported by inner chocks 7b and outer chocks 7a which are connected to each other by means of springs 16. If the rolling reduction forces generated by the rolls 4 are released for the purpose of replacing the rolls 3, the pair of inner chocks 7b are moved horizontally in the guard holes 17 provided to the chocks 7a by the elastic forces of the springs 16, and are held at the end faces thereof.

摘要： PURPOSE:To control a material to be rolled to good shapes by making intermediate rolls movable in their axial center directions and providing means which apply roll bending forces independently upon the intermediate rolls and the work rolls. CONSTITUTION:Pressure is applied respectively at both ends of work rolls 2 and intermediate rolls 3 by means of oil hydraulic cylinders 11 and 12 to act bending forces which negate the deflections of these rolls by rolling load. Then the rolls 3 bend along divided backup rolls 4, and the rolls 2 bend along the rolls 3. When the rolls 3 are moved in their axial center directions to bring the crowned parts close to the end parts of a material 1 to be rolled, the parts of the rolls 2 projecting from the material 1 are released of bending restraints by the rolls 3, and the parts of the rolls 2 near the end part of the material 1 are bent to a projecting shape by the bending forces of the rolls 2 and the distributions of the rolling reactions from the material 1, whereby edge drops are prevented.

摘要： PURPOSE:To improve the effect of controlling shapes considerably by supporting each one of intermediate rolls by means of two sets of upper and lower metal chocks, and making the rolls freely movable respectively independently in the direction parallel to the advancing direction of a rolling material. CONSTITUTION:The bearing parts 17 of intermediate rolls 3 are supported by metal chocks 7, and the chocks 7 are bisected like 18, 19 perpendicularly on the axial lines of a pair of upper, lower work rolls 2 so as to be made movable respectively independently in a horizontal direction, whereby the spacing between the rolls 3 can be hanged freely. When the rolls 3 receive ununiform rolling load by plural backup rolls, the rolls move automatically in a horizontal direction to exert pressure uniformly upon the contact surfaces of the work rolls, whereby always the best rolling load is transmitted.

摘要： PURPOSE:To obtain a titled device which can deal with high speed removal of scale from the surfaces of steel strips and has good efficiency by providing plural centrifugal projectors for abrasive materials above and below via separators on both sides along an approximately vertical by-pass line on the midway of a conveying line for steel strips. CONSTITUTION:A hot rolled steel strip 1 is fed by a tension imparting device 6 into a frame body 8, passes through a by-pass line, emits from the body 8 and is fed with a tension imparting device 7. In the pass line in the body 8, abrasive materials 15 are projected by centrifugal projectors 9a-14a, 9b-14b to the front and rear surfaces of the strip 1, whereby scale is removed. Here, the mutual interferences of the materials 15 from the projectors 9a-14a, 9b- 14b arrayed in a vertical direction are prevented by separators 16a-19a, 16b- 19b, and act effectively upon the strip 1 by each projector.

摘要： PURPOSE:To lessen damage due to differential abrasion by forcedly lubricating between a boring main spindle and a milling main spindle. CONSTITUTION:A lubricating device includes a pressure storage chamber 16 filled with lubricating oil which of formed on the outer peripheral portion of a milling main spindle 1, a hole 18 for connecting between the pressure storage chamber 16 and the inside diameter portion of the milling main spindle 1, and means comprising a piston 13 for feeding lubricating oil in the pressure storage chamber 16 through the hole 18 to the inside diameter portion of the milling main spindle 1 by pressure. Lubricating oil filling the pressure storage chamber 16 is discharged by working of a piston 13 pressed by a spring 15 to pass through the hole 18 to an oil groove (not shown) mounted on the inside diameter portion of the milling main spindle 1, so that the periphery of a contact surface between the milling main spindle 1 and a boring main spindle 6 is supplied with adequate lubricating oil. Therefore, even if a milling tool is mounted on the end portion of the boring main spindle 6 to perform milling, there is a slight differential abrasion generated at a contact surface between the milling main spindle 1 and the boring main spindle 6.
