Abstract
Torsion guide (10) comprising a support body (11) with which there are associated at least two torsion rollers (12, 13) rotatable around respective parallel rotation axes (T1, T2), distanced with respect to each other at least in a direction of adjustment (B) perpendicular to said rotation axes (T1, T2) and disposed on respective support elements (17, 18).
Claims13
Torsion guide comprising a support body with which there are associated at least two torsion rollers, rotatable around respective rotation axes (TI, T2) parallel to each other, wherein said torsion rollers are pivoted to respective support elements which are mobile at least in parallel to an adjustment axis (B) and are mechanically connected to at least one motor mean, characterized in that it comprises a control and management unit and one or more means for detecting the reciprocal position of said torsion rollers at least in a direction parallel to said adjustment axis (B), said detection means being configured to transmit data correlated to the positions of said torsion rollers to said control and management unit in order to allow to adjust the reciprocal position of said torsion rollers at least in a direction parallel to said adjustment axis (B).
Rolling method that provides to:
- reduce the thickness of a metal product (P) by means of a first rolling stand;
- transmit a first torsion to the metal product (P) at exit from the first rolling stand (51) by means of a torsion guide provided with at least two torsion rollers pivoted to respective support elements which are mobile at least in parallel to an adjustment axis (B) and are mechanically connected to at least one motor mean, a control and management unit and one or more means for detecting the position of said torsion rollers at least in a direction parallel to said adjustment axis (B), which are configured to transmit data correlated to the positions of said torsion rollers to said control and management unit;
- directly or indirectly detect the wear of the torsion rollers;
- automatically adjust the reciprocal position of said torsion rollers, at least in a direction parallel to said adjustment axis (B), on the basis of said detection of the wear of said torsion rollers.
