    Abstract: A method and apparatus for the contactless determination of planarity and a ferromagnetic metal strip during transit of the strip through a strip-processing line or cold-rolling line. Hysteresis loops repetitively impressed in the metal strip and the tangential magnetic field strength is measured at a surface thereof and electromagnetic parameters are determined from the time course of the tangential field strength signal. The parameters are functions of the mechanical stress which is evaluated to determine residual intrinsic stress distribution and then the planarity or nonplanarity of the strip.

    Abstract: The bridle or bridles of a stretching or levelling line for a thin metal strip, e.g. of a thickness of up to 1 mm, can have at least one roll of a periphery variable between an outwardly convex and an inwardly concave bulge to compensate for dishing of the strip or edge waviness.

    Abstract: A method and an arrangement for continuous tension stretching of thin metal strips. The strip is conducted through a set of brake rollers and a set of pull rollers and the strip is subjected to a stretch-forming or stretch pull operation between the two sets of rollers for stretching the strip in the plastic range, wherein the stretch pull force corresponds to the yield point of the strip material. The strip is subjected between the set of brake rollers and the set of pull rollers only to a stretch-pull which is required for stretching the strip in the plastic range. As a result, transverse elongation during plastic stretching is minimized, so that center troughs no longer occur and, when the strip is longitudinally divided, the strip portions no longer have unequal side lengths.

    Abstract: A thin metal strip is made by hot-rolling a strip workpiece, stretch-bend leveling the hot-rolled strip workpiece immediately after hot-rolling it, tensioning the strip workpiece with a predetermined tension while stretch-bend leveling it, and thereafter coiling up the workpiece. In addition the workpiece is rapidly cooled immediately after stretch-bend leveling it and before coiling it up. Thus the workpiece is stretch-bend leveled before it cools so it can be treated while still about 1100.degree. C., at which temperature it is still very plastic. The workpiece can therefore be deformed greatly while under modest tension, so as to produce a very thin product that is very uniform. The tension in the strip merely serves to keep the workpiece looped over as much an arc as possible around the stretch-bending rolls.

    Abstract translation: 通过热轧带钢工件制造薄金属带，在热轧后立即对热轧带材工件进行拉伸弯曲，并以预定的张力张紧条带工件，同时拉伸弯曲平整，然后卷绕 工件。 此外，工件在拉伸弯曲后立即迅速冷却，然后卷起。 因此，工件在冷却之前进行拉伸弯曲平整，因此可以在约1100℃下进行处理，在该温度下仍然是非常塑性的。 因此，在适度的张力下，工件会发生大的变形，从而产生非常均匀的非常薄的产品。 条带中的张力仅用于使工件在拉伸弯曲辊周围保持尽可能多的圆弧。

    Abstract: A roll for a hot- or cold-rolling stand has a core having an outer surface centered on an axis and a pair of axially opposite ends and respective conduits extending through the core and opening adjacent the ends thereof. A sleeve having an outer surface, axially opposite ends, and an inner surface centered on the axis coaxially surrounds the core. One of the surfaces has a central portion projecting radially toward and engaging the other surface between the ends in all-around annular contact. Respective elastic and annular seals engage radially between the ends of the rolls, that is each seal engages betwen one end of the sleeve and the corresponding end of the core. These seals define respective annular compartments at the ends, between the roll surfaces, and subdivided axially from each other by the central portion of the one surface. Each conduit opens into a respective one of the compartments. The compartments can be pressurized via the respective conduits to change the shape of the outer surface of the sleeve at least at the compartments.
