摘要:
Method to control the profile of a strip (13) in a rolling stand for strip and/or sheet comprising at least two working rolls, respectively upper (11a) and lower (11b) and defining a reference pass-line (15) substantially coinciding with the center line of said strip (13), said rolls (11a, 11b) defining between them a transit gap (12) through which said strip (13) passes and is rolled and being supported at the ends by respective chocks, said method providing the axial movement (shifting) of said working rolls (11a, 11b) with respect to said pass-line (15), said working rolls (11a, 11b) having a shaped surface profile (14) which can be expressed by a polynomial equation, said method providing to apply a first value ("s1") of axial translation, or shifting, to said upper working roll (11a) and a second value ("s2") of axial translation, or shifting, to said lower working roll (11b), s1 being ≠ s2.
