摘要： A method and a machine for straightening sections by eliminating multi-axle deviations from the required section and from the required straightness using one or more straightening tools arranged, in series above and below the material to be straightened, on straightening axles which are parallel with one another. The adjustment of the straightening force and the adjustment of the horizontal inclination of the adjustable straightening axle are carried out hydraulically. The hydraulic system is configured so that a rapid change in position is possible either at the front and rear hydraulic cylinders or exclusively at the rear hydraulic cylinder in such a way that the straightening force and/or the horizontal inclination of the adjustable straightening axle can also be set during the straightening process.

摘要： A piercer roll exchanging apparatus for use in a vertical piercing mill, as well as a piercer roll exchange method for use with the apparatus, which can automate the exchange of piercer rolls and which are suitable for flexible manufacture of small quantities of seamless steel tubes of a variety of sizes. The apparatus comprises a traveling carrier car capable of moving while carrying upper and lower cradles thereon, and a cradle shifter mounted on the traveling carrier car. The cradle shifter shifts the upper and lower cradles from a traveling end position to the interior of a piercing mill body. The cradle shifter includes a spacer clamp for clamping a cradle-to-cradle spacer and for adjusting the vertical position of the spacer, as well as a lower cradle clamp. According to the present invention, automation of piercer roll exchange work and shortening of the exchange time can be attained by means of a simple structure and without deterioration of workability.

摘要： A method for the flexible rolling of a metallic band wherein, during the rolling procedure, the metallic strip is lead through a roll gap which is formed between two working rolls and which is set so that, over the length of the metallic strip, strip sections are obtained with different strip thickness. In order to prevent temperature-related deviations in the thickness and length profiles of the metallic strip, a compensation of the temperature influence effecting the metallic strip is carried out during rolling in order to prevent deviations from the theoretical thickness and/or the theoretical length of the individual strip sections at a default temperature of the metallic strip.

摘要： Vibration damping apparatus (40) includes a body in the form of backup roll balance piston (42) positionable for sliding movement in an enclosure in the form of cavity (44) in the lower backup roll chock (30) of the mill stack (10). The body of the piston is a casing which performs the role of a conventional postion. A damping means is integral with the piston (42) for providing vibration damping of opposing backup roll chocks (24, 30). The damping means is a specially designed absorption system to provide tuned stiffness and damping elements which act in parallel and are located in compartment (46) at an uppermost end or cap of the piston (42). A second vibration absorbent compartment portion (56) of the piston (42) also includes vibration absorbing components. Portion (56) is an integral cap located at the end of the piston (42) in contact with the fluid (52).

摘要： In a cluster type split housing type rolling mill, the plate thickness control capability is improved by maintaining maximum mill rigidity. An upper inner housing supporting an upper group of rolls is supported at two points in a rolling pass direction at upper outer housing sections. A lower inner housing supporting a lower group of rolls is supported at a single point in the rolling pass direction at lower outer housing sections. The upper and lower housings have different levels of vertical rigidity.
