    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: Rolling stand for producing rolled strip, which includes work rolls, which are supported on backup rolls or intermediate rolls and backup rolls. The work rolls and/or the backup rolls and/or the intermediate rolls can be axially shifted relative to one another. The barrel length (L) of each intermediate roll in a six-high rolling stand or of each work roll in a four-high rolling stand has a cylindrical roll barrel section (Z) and a convexly curved roll barrel section (R(x)), such that the transition point from the cylindrical to the curved roll barrel section, calculated from the cylindrical end of the roll barrel, is in the range of L/2≦x

    摘要: A method for continuous casting and rolling at increased casting speed followed by hot rolling of relatively thin metal strand, especially steel strand (1), where presetting of target temperatures (6) of the hot strip (2) reduces temperature losses in the hot strip (2) by increasing the temperatures of the work rolls (4) at a predetermined rate of increase, starting from a low initial temperature (5), and by adjusting the strip temperature (15) to a target rolling temperature (6) of the hot strip (2) and/or by automatically controlling or regulating the intensity of the roll cooling (18).
