    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: In a continuous hot rolling system, at least one melt-cut torch is set in a predetermined positional relationship with respect to a trailing end of a preceding hot material and a leading end of an adjacent succeeding hot material. An injected flow of cutting gas from the melt-cut torch is blown against a portion of at least one of the trailing end of the preceding material and the leading end of the succeeding material to melt-cut the portion. The portion extends from an end surface of the one end over a predetermined length. The trailing end of the preceding material and the leading end of the succeeding material are forced against each other and are butt-joined to each other. By doing so, there are produced joining surfaces superior in surface accuracy and high in temperature, to allow joining to be high in accuracy and strength. This joining may be made with respect to slabs before rough rolling, or may be made with respect to bars after rough rolling. Further, a slab manufactured by a continuous casting machine are reduced in thickness at a plurality of desired locations to form a plurality of thickness-reduced portions. Cutting is made at the thickness-reduced portions. The cut thickness-reduced portions are joined to each other. Furthermore, the ends of the respective materials after having been cut are reduced in thickness with the ends abutted against each other to form thickness-reduced portions. The thickness-reduced portions are joined to each other.

    摘要: A rolling mill has a work roll and a back-up roll for supporting the work roll vertically and driving it. A plurality of horizontal support rollers contact the work roll at barrel diameter outside the rolling region and at a both horizontal sides of the work roll and act to fix the position of the work roll in both horizontal directions during rolling and to oppose horizontal rolling forces. In order to reduce the bending of the work roll during rolling, there are provided means for applying horizontal counterbending forces to the work roll comprising members e.g. rollers, contacting the work roll at locations axially further from the rolling region than the support rollers and actuator means for urging the members against the work roll. The counterbending forces being in the same direction as the net horizontal force applied to said work roll by said back-up roll and the material being rolled. Preferably at least one condition of said work roll is sensed during rolling, and there are control means acting during rolling to control the counterbending forces in dependence on the sensed condition.

    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: 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: A work roll cross type rolling mill comprises a pair of work rolls and a pair of back-up rolls for backing up the work rolls. The back-up rolls are so arranged that their axes can be inclined within horizontal planes only to three or four specific angular positions. The work rolls are allowed to be inclined within horizontal planes with respect to the back-up rolls such that the axes of the work rolls cross the axes of the associated back-up rolls and cross each other. The nip between each the work roll and the associated back-up roll is lubricated so as to reduce axial thrust generated therebetween due to the crossing of the rolls. The cross angle between the work rolls is set and controlled during rolling operation only when the roll peripheral speed or the rolling speed is 50 m/min or higher. Advantages of work roll cross type rolling mill are fully extended to realize stable rolling without trouble so as to ensure high quality of the rolled product while achieving higher rate of operation of the mill with facilitated operation.
