Abstract
Method and device to control between rolling stands the drawing of the rolled stock (14) in a segment (10) of a rolling line, the segment (10) possibly comprising two conventional rolling stands with or without an interposed drawing unit (19), a conventional rolling stand and a drawing unit (19), a rolling stand and a fast rolling block (11a), two fast rolling blocks (11a, 11b) with an intermediate thermomechanical treatment or another type of combination of rolling units, there being included a possible intake drawing unit (12) and a possible discharge drawing unit (13) associated with a shears (20), the method including the measuring of the drawing action applied to the rolled stock (14) in the segment between stands comprised between two rolling units, one upstream (11a) and the other downstream (11b) and/or between a rolling unit and the relative drawing unit (19). The measurement of the drawing action is achieved by a dimensional measuring of a significant dimension of the rolled stock (14) carried out at least two measuring units at at least two points of the segment (10) between stands, at least one of which points is placed immediately at the discharge of the upstream rolling unit (11a). The measurements are compared and the result of the comparison correlated to the value of the drawing action exerted on the rolled stock (14).
