Abstract:
A method of shaping metal strip in a hot strip rolling mill including a rolling train and a cooling line, a pinch roll unit composed of an upper pinch roll and a lower pinch roll and a coiling unit downstream of the rolling train, and a stretcher-leveller zone between an end of the cooling line and the coiling unit, the stretcher-leveller zone having at least two successively arranged stretcher-leveller work rolls, wherein the stretcher-leveller work rolls are arranged offset relative to each other, such that the metal strip is deflected at each stretcher-leveller work roll, the method comprising conducting the metal strip alternatingly over and under at least two successive stretcher-leveler work rolls which form the stretcher-leveller zone, further comprising controlling by means of a first controlled circuit an adjustment of the stretcher-leveller work rolls relative to each other and to the strip in dependence on at least one of strip properties and properties of the pinch rolls or the stretcher-leveller work rolls.
