Title (EN) VIBRATION DAMPING SYSTEM FOR A ROLLING MILL WITH FIRST AND SECOND PASSIVE HYDRAULIC ELEMENTS
(FR) SYSTÈME D'AMORTISSEMENT DES VIBRATIONS POUR UN LAMINOIR
Abstract: front page image
(EN)The present application relates to a vibration damping system for a rolling mill comprising a rolling cage and a bending adjustment system (3,3') of the rollers comprising hydraulic actuators acting on the rollers and hydraulic circuits (18, 19) for feeding, and hydraulic damping means (25, 31, 32) of a force connected to the hydraulic circuits (18, 19) for actuating a damping effect by means of the hydraulic actuators. The hydraulic damping means comprises a pair of hydraulic pumps (25B, 25C) or a pair of hydraulic cylinders with a dual chamber, connected in an opposite direction to each other to the hydraulic circuits (18, 19).
(FR)L'invention concerne un système d'amortissement des vibrations pour un laminoir comprenant une cage de laminoir et un système d'ajustement de flexion (3, 3', 17, 18, 21, 21' et 22, 22' et 23, 23' et 24, 24') des rouleaux (1, 1'), comprenant des actionneurs hydrauliques (21, 21' et 22, 22', et 23, 23' et 24, 24') agissant sur les rouleaux (1, 1') et des circuits hydrauliques (18, 19) d'alimentation, ainsi que des moyens d'amortissement hydrauliques ((25, 31, 32), (27, 28, 45, 46, 42), (29, 30, 56, 58, 59, 70)) d'une force (Fv) connectés aux circuits hydrauliques (18, 19) pour exercer un effet d'amortissement au moyen des actionneurs hydrauliques (21, 21', et 22, 22' et 23, 23' et 24, 24'). Les moyens d'amortissement hydrauliques peuvent comprendre une paire de pompes hydrauliques (25B, 25C, 45B, 45C) ou une paire de cylindres hydrauliques (59, 69) avec une chambre double, raccordée, dans une direction opposée l'une à l'autre, aux circuits hydrauliques (18, 19).
