摘要： A roll bending apparatus for use in a multi-stage rolling mill adapted for rolling a hard material or a thin sheet material with a high uniformity of thickness along the breadth, with a high degree of accuracy and low energy. The rolling mill has work rolls of a comparatively small diameter. The amount of bend of the small-diameter work roll is controlled by the roll bending apparatus for attaining the high degree of uniformity of thickness along the breadth of the rolled material. The roll bending apparatus has, for each of said work rolls, a supporting member having a work roll supporting portion for rotatably supporting the work roll and rockable vertically about a fulcrum, and a bending force generating means adapted for engaging the supporting member so as to cause a rocking motion of the supporting member thereby applying a substantially vertical roll bending force to the work roll through the supporting member.

摘要： A multi-high rolling mill is disclosed which includes an upper work roll backed by an intermediate roll and a backup roll and a lower work roll backed up by a single backup roll. Control benders are provided on each of the intermediate roll and the upper and lower work rolls. In order to optimize the control of the rolling operation for skinpass rolling and the like, the control benders for the upper work roll and the intermediate backup roll are controlled so as to effect a control of the crown sheet over the entire width of the material being rolled, while the control bender for the lower work roll controls the sheet crown of the rolled material at the lateral side end portions, resulting in a composite control substantially improving the sheet quality and preventing edge wrinkles in the material being rolled. In the disclosed embodiments, the intermediate roll has a larger drum length than a predetermined maximum sheet width of rolled material to be rolled by the work roll. The shape of sheet material is sensed by a shape detector which provides a signal to a controller which actuates the roll benders.

摘要： By rolling a slab with a thickness of 80 mm or less in a plant including a continuous casting machine and a hot strip rolling mill directly combined with each other, low-speed rolling can be achieved while suppressing a drop of the strip temperature and the occurrence of scales. After a slab 2 cast by a continuous casting machine 1 and being 80 mm or less thick is heated and descaled, it is rough-rolled into a bar with a thickness of 20 to 60 mm by a roughing mill 7 constructed as a 4H-twin mill. After being heated and descaled again, the bar is finish-rolled by finishing mills 19 to 21, each of which employs small-diameter work rolls having a diameter not larger than 500 mm, into a thin plate with a thickness in the range of 1.6 mm to 15 mm or a thick plate with a thickness in the range of 3 mm to 40 mm. The rolling speed on the delivery side of the finishing mills 19 to 21 is set to be as low as 350 m/minute or less with a result of small production scale, and the plant length is set to be not longer than 100 m with a result of small plant space.

摘要： In a continuous hot strip rolling system in which bars are joined between a roughing train and a finishing train for continuous rolling, the roughing train includes two two-high twin-roll arranged stands each having two pairs of work rolls. The four two-high mills provided by the two twin-roll arranged stands including four pairs of work rolls are disposed close to each other so as to provide a tandem rolling in which a material to be rolled is rolled simultaneously by the two adjacent mills. A slab having a thickness of 200 to 240 mm is rolled by the two twin-roll arranged stands to obtain a bar of about 80 mm. A width press is provided near the entrance of the No. 1 stand. A descaling device is provided at the entrance of each of the two stands. The descaling device has a nozzle which is movable in the direction transverse to the direction of travel of the material to be rolled. A non-driven roll edger is provided at the exit of each of the two stands. Thus, generation of camber in the roughing rolling process can be reduced, and stable joining continuous rolling can be conducted. Furthermore, the overall length of the system can be reduced, and reduction in the bar temperature, which occurs until the bar reaches the joining position, can be lessened. Rational bar joining can be conducted.

摘要： A widthwise bend of an end of a hot-rolled elongate sheet-shaped metal product is corrected while it is hot. The correction comprises simultaneously:(i) holding the edges of the product at at least two positions longitudinally spaced along the product thereby to hold, at least laterally, a portion spaced from the bent end, and(ii) pushing the end portion laterally by means of a laterally moving member. The method may be performed while the product is continuously moving along a path. Both steps (i) and (ii) are performed by rollers rotatable about vertical axes.

摘要： An apparatus for looping belt-like materials, including first and second looping units for winding a moving belt-like material helically into first and second coils, with a portion of the belt-like material forming the first coil being drawn out into the second coil. A plurality of support rollers annularly arranged along each of the portions of the wound belt-like material forming the first and second coils, and frames are provided with the support rollers, along with a drive for applying a rotary force to the frames. The support rollers are displaceable in a radial direction of an imaginary circle along which the support rollers are arranged in accordance with variations in diameters of the coils so as to bring the support rollers into contact with the portions of the belt-like material which constitute the coils. The support rollers are annularly arranged along inner circumferential surfaces of the coils, with the drawing of the portion of the first coil being effected by a plurality of small-diameter rollers, arranged along a curved surface of an imaginary cone or cylinder in such a manner that the small-diameter rollers can be rotated in the direction in which the belt-like material is drawn out.

摘要： The work rolls of two sets of roller groups are held within one-piece metal chock in a rolling mill. A one-piece metal chock in which the driving side and operating side are separate then provides support at the upper part of the rolling material, with support similarly being provided at the lower part using another pair of single piece metal chocks. Two sets of roll groups can then be arranged close to each other, strip walking and strip curving can be prevented, and a rolling mill, rolling method and rolling installation that are easy to maintain and provide superior rolling efficiency can be provided.
