摘要： A method of controlling a rolling mill production system for production of a coil-shaped end product from a slab, the production including processing the slab by sequentially arranged production units, the processing by the production units resulting in a respective strip-shaped product having physical data, the method including modeling, under consideration of the physical data, the processing of a testing product by a plurality of production units arranged downstream from a given production unit while taking into account the physical data. If the modelling shows that, under consideration of the physical data, one of the products resulting from processing by the downstream production units does not meet a predetermined quality criterion, the intended manufacture of the product is interrupted and a signal relating to the interrupting is outputted.

摘要： The invention relates to a method for rolling strips in the roll stand of a rolling mill, wherein said roll stand consists of two axially displaceable working rollers which are provided with a CVC-grinding or a similar contour and whose curved profile is expressed in a third or higher-order polynom and, simultaneously with simple handling of working rollers with large possibilities of adjusting the profile and flatness, the aim of said invention is to homogenize the working rollers wear. For this purpose, the increased cyclic shifting of the working rollers is induced or forced by a cyclic variation of the setting values of the curve of the working cylinders from one strip to another in a predetermined part of the adjustment range thereof, wherein the combined the action of the two adjustment systems (the curve of the working cylinders and the shift thereof) enables the parabolic effects of said two adjustment systems to supplement each other with a high approximation, thereby ensuring the flatness and, in addition, optimally homogenizing the working roller wear.

摘要： A device and method for prediction and/or control of the profile and/or shape of rolled metal strip. The device and method are compatible with both cluster-type and non cluster-type mills. The device and method employ a customized deflection model of the rolling mill, thereby combining the advantages of well-known finite element method with other relevant methods to allow real-time operation of the rolling mill without the computational complexities of such methods. In one form, the customized deflection model helps to obtain a compact, linear, and flexible analytical model with non-iterative solution, multiple continuous elastic foundations, third-order displacement fields, simple stress-field determination, and capability to compute dynamic deflection characteristics.

摘要： A rolling method and a rolling apparatus for flat rolled metal materials stably produce flat-rolled metal having no or extremely little camber. The rolling mill having work rolls with split backup rolls supporting at least one work roll is provided with at least one pair of pinch rolls. The pinch rolls apply tension to the rolled material. The difference between the rolling direction force acting on the pinch rolls at the right and left sides is calculated. Optionally, the rolling direction force acting on the work rolls at the right and left sides is also calculated. The left-right difference of the roll gap of the work rolls is controlled as a result of the calculated difference.

摘要： An apparatus and method are provided for reducing the width of a plurality of longitudinal slots or other openings spaced circumferentially around a slotted tubular member. The invention includes a seaming roller positioned to contact the outer surface of the slotted tubular member for transverse movement across the plurality of slots, and adapted to apply a force onto the slotted tubular member so as to reduce the slot width. The width of the plurality of slots is detected and compared to a set value indicative of a desired end slot width and based on this comparison, an adjustor connected to the seaming roller, adjusts the force applied by the seaming roller to the plurality of slots. Each opening is adjusted by the seaming roller to have a profile with a width that throughout the length of the slot profile, varies no more than a given tolerance from the desired end slot width. The invention also provides a slotted tubular liner comprising a metal slotted tubular member formed with a plurality of longitudinal slots ≦3.175 mm in width spaced circumferentially around the member, each slot having been cut and then transversely seamed to have a profile with a width tolerance, that throughout the length of the slot profile, varies no more than +/−0.0127 mm, and preferably varies no more than +/−0.00762 mm from a desired end slot width.

摘要： The invention relates to a method for specifically adjusting the surface structure of rolling stock (3) during cold rolling in skin pass mills. The aim of the invention is to partially transfer the surface structure of the working roll (2) onto the rolling stock (3). To this end, the change of roughness of the rolling stock (3) in the rolling process of a single- or multiple-stand, preferably two-stand skin pass mill is calculated in an optimization calculation in which the rolling parameters are varied according to the mill capacity using a tribological model that mathematically describes the friction conditions in the roll gap (1). The results obtained are then used to readjust at least a part of the rolling parameters used for calculation.

摘要： A hard metal or non-metal member can be formed or shaped to have varying amounts of curvature and tapering by passing the member through a forming channel defined by two sets of opposed, axially displaceable rollers which can be dynamically moved horizontally and vertically in a predetermined range. The rollers are controlled by a computer, a translator, and a electro-mechanical displacement system such as a servo motor. Using data input by a user or preprogrammed instructions containing displacement instruction in the computer, the computer can subsequently instruct servo motors, via a translator, to move the rollers in the available axial directions. The servo motors may include a mechanism for converting rotational movement into fine linear mechanical movement of the rollers. The timing and rate of movement, direction, and force of the roller can be controlled to form and shape the member into a specific contour of curves or tapering sides.
