    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 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.

    摘要翻译： 本发明涉及一种用于施加可调拉伸应力分布的方法和装置，特别是在金属条（16），特别是金属箔的冷轧过程中的边缘区域中，以减少过度的风险 在带材的边缘处形成张力和裂缝，这可能导致带材中的裂纹的负面影响和生产的减少，并且为了改善条带的表面及其平面性，即使对于 相对较高的条带位移速度，并且还减少条带修剪宽度。 为了实现这些目标，实施以下两种措施中的至少一种或两种组合：a）通过润滑在进料侧和在排放侧进行冷却来分离工作辊的润滑和冷却，b）额外的影响 特别是通过在区域中喷涂（21）不同温度的轧制油，c）使用工作辊（12,12'）附近的特殊横截面构造 带状边缘在开花过程中产生部分材料堆积，所述堆积形成具有随后通过的较长条带边缘，从而抵消拉伸应力过度累积的风险。

    摘要： A system for rolling metal sheet having a substantially uniform flatness including a rolling mill including a pair of work rollers for reducing the thickness of a metal sheet, an induction heating apparatus in close proximity to at least one roller, bending jacks corresponding to each of the rollers, and a cooling spray system in proximity to rollers; a flatness measuring device positioned to measure a differential in flatness of the metal sheet; and an mill control interface connected between the flatness measuring device and the rolling mill's actuators, in which the mill control interface is configured to actuate the induction heating apparatus, the bending jacks and the cooling spray system to substantially eliminate flatness differentials is the metal sheet's flatness. The induction coil heating apparatus is configured to eliminate high tension on the strip edges caused by the temperature gradients in the work rolls at the edges of the metal strip.
