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).

Abstract: Method to regulate the pull in continuous rolling trains, in which the value of a reference speed (V) is monitored in conditions where a bar is substantially free (not under drawing action) while said bar is being rolled, in which the measurement of the value of the reference speed (V) when the bar is substantially free of pull is obtained by means of variation of the speed (V) of the motor of the involved stand by an increase (x1) of the speed (V), by a return thereafter to the reference value of the speed (V) and by a reduction (x2) of the speed, followed by a final return to the reference speed (V) or realigned speed (V'), while monitoring the formation of a microloop on the rolled product. Rolling train for carrying out the above method, comprising for each stand an assembly to sequence a change of speed connected to a speed cascade control assembly and to an incremental assembly.

Abstract: Device to intensify the magnetic field in an ingot mould, the device cooperating with an ingot mould body (10) and with a means (11) which is positioned outside an outer jacket (14) of the ingot mould body (10) and generates a magnetic field, whereby independent, replaceable auxiliary extension pole pieces (18) stretching substantially towards a crystallizer (12) are comprised within outer jacket (14) of the mould body (10) in correlation with pole pieces (16).
