摘要： The invention relates to a Sexto-type roll stand with x3 grinding, in which a large difference in diameter between the intermediate rolls (20, 21) causes increased wear and rough surfaces on the support rolls (31, 31) during operation, the damage pattern on the support rolls (30, 31) corresponding to the shape of the CVC grinding following an extended operating time. In Quarto-type roll stands, the grinding amplitude is initially also significantly greater than is required for rolled programs, thus resulting in the unfavorable wear pattern as well on the support rolls. The aim of the invention is to minimize said flaws. Said aim is achieved by the fact that the surface length (L) of each intermediate roll (20, 21) in a Sexto-type roll stand or each working roll in a Quarto-type roll stand is composed of a cylindrical section (Z) and a convexly curved section (R(x)). The transition point (A) from the cylindrical to the curved section of the surface length of the rolls can be selected within the range L/2

摘要： In a positioning control device for guiding the side edges of an elongated strip at the entrance into a hot-rolled wide strip finish rolling mill train, guidance feed members are displaced transversely of the rolling direction by piston-cylinder assemblies. Appropriate displacement of the guidance feed members depends on continuously transmitted measured actual values of the strip position within the rolling train which are compared with preset required values. If the width of the strip exceeds a nominal width then large deformation of the strip side edges occurs along with axial reaction forces in the roller supports of the first rolling stand in the finish rolling mill. To avoid damage to the first rolling stand and to the strip, a pressure regulation is superimposed on the position regulation and depending on a comparison of the actual value of the measured upsetting force acting along the strip side edges with a predetermined required value, a correction-setting signal is generated for the displacement of the guidance feed members in the opening or closing direction relative to one another.

摘要： The device serves to control the desired lifting and pressure-containing movements of strip pressure rolls for the reels which serve to store hot rolled strip. These reels have a rotating mandrel. The pressure rolls are actuated by piston and cylinder units for positioning the rolls electro-hydraulically in conformity with signals which indicate the relative position of the leading strip edge which rotates with the mandrel. The positioning of the roll, by the lifting and pressure-contacting movements, is effectd by position control with subordinated pressure control in a closed-circuit position control loop and a closed-circuit pressure control loop, by input of a setpoint position value which corresponds to the respectively prevailing pressure-contacting and lifting position of the pressure rolls, and by establishment of limited setpoint pressure values for both functions or directions of movement.

摘要： A metallic strip is hot-rolled in a succession of roll stands arranged in a row by passing the strip longitudinally in a travel direction through the stands. The strip is then compressed in the upstream stands to substantially reduce its thickness measured perpendicular to the travel direction and parallel to the strip while substantially increasing its width measured perpendicular to the travel direction and transverse to the strip. Then in the downstream stands it is compressed and tensioned without substantially increasing its width to level it and stretch it longitudinally in the travel direction. With standard steel strip this critical thickness is about 12 mm. The local band thickness is measured downstream of the upstream roll stands and the furthest downstream stand of the upstream stands is operated to eliminate any nonuniformities in thickness thus detected. The nonuniformities are detected by comparing the local band thicknesses detected with standard set-point thicknesses.

摘要： The invention relates to a method and a device for applying an adjustable tensile-stress distribution, in particular in the edge regions during the cold-rolling of metal strips (16), in particular metal foil, in order to reduce the risk of an excessive build-up of tension and cracks at the edges of the strip, which can lead as a negative consequence to cracks in the strip and to a reduction in production, and in order to improve the surface of the strip and its planarity, even for a relatively high strip displacement speed, and also to reduce strip trimming widths. To achieve these aims, at least one or a combination of two of the following measures are implemented: a) separation of lubrication and cooling of the working rolls by lubricating on the run-in side and cooling on the e discharge side, b) additional influencing of the strip edges using a hot edge spray”, in particular by spraying (21) rolling oil with differing temperatures in zones, c) use of a special cross-sectional configuration of the working rolls (12, 12′) in the vicinity of the strip edges, which creates a partial material build-up during the blooming pass, said build-up forming a longer strip edge with subsequent passes, thus counteracting the risk of an excessive build-up of tensile stress.

摘要： A rolling mill stand with work rolls which are supported as necessary by back-up rolls or by intermediate and back-up rolls. The rolls are axially slidable relative to each other. The bodies of the rolls are provided with alternatingly concavely and convexly shaped contours in such a way that the rolls supplement each other in at least one axial position of the rolls so that no gap exists between the rolls. Corrections of the roll gap between a pair of rolls can be carried out by relative axial displacement of the rolls. The contours of the rolls have in the neutral position thereof, in addition to a maximum inclination in the middle, maximum inclinations of the circumferential lines on both sides of the middle of the circumferential surfaces of the rolls in longitudinal direction of the rolls in which roll gap profile changes are to be effected.
