Procedure for adjusting the position of a cylinder in a rolling mill stand of a rolling mill and a rolling system comprising a position calibration and for carrying out the method

摘要

Method for adjusting the position (z0) of at least one cylinder (2, 3, 4) in a support mill (1) ofa laminator, housing support mill (1) at least one roll stand (5) with a number of cylinders (2, 3, 4), each cylinder (2, 3, 4) being arranged in a regulating mechanism cylinders (6, 7, 8) and estandoprevistos means (9) requesting regulatory mechanisms cylinder (6, 5 7, 8) for regulating loscilindros (2, 3, 4) relative to the roll stand (5), characterized in that the method comprises the following steps: a) providing at least one box lamination (10) with cylinders (2, 3, 4) in a position calibration; b) biasing mechanism regulating cylinders (6, 7, 8) with a force (F) in a direction deregulation (z), so that the cylinder (2, 3, 4) tightened with a contact point (11 ) defined unasuperficie against contact (12) of the roll (10) as the calibration and measuring the actual size (13) of the cylinder (2, 3, 4) in this position (a); c) determining the deviation value (Dz) in the adjustment direction (z) between the position (A) according laetapa b) and cylinder position for an ideal gauge (z0); d) installation of the roll together with the cylinder (2, 3, 4) of the position calibration in delaminator support (1) of the mill and biasing mechanism control cylinders (6, 7, 8) with a force (F) in the adjustment direction (z), so that the cylinder (2, 3, 4) tightened with a contact point (11) definidocontra a contact surface (14) of the roll (5) installed in the mill stand (1) dellaminador; e) adjusting the adjustment mechanism cylinders (6, 7, 8) against the adjustment direction (z) as quecorresponde the offset value (Dz) and service start rolling in the rolling mill with the setting (z0) thus obtained mechanism regulating cylinders (6, 7, 8) and the cylinder (2, 3, 4) for the roll (5) ready for operation.
