Device for measuring the roll gap between the work rolls of hot roll stand or cold roll stand

摘要

The present invention, by using (6) roll gap sensors, the signal of the sensor nip, nip - the servo valve of a hydraulic control mechanism for the piston-cylinder units influencing the roll gap (7) as a reference value style given Furthermore, the metal strip of wide or narrow, for rolling the non-ferrous metal strip in particular, the work roll of hot rolling stand or cold roll stand; roll gap of (1a 1b) between (7) It is a device for measuring. The object of the present invention is to provide a measurement mechanism of an appropriate nip In the case where the strip is laterally offset in this manner. For the accomplishment of its task, cylinder deflection acting negatively or positively; for through (5a 5b), is carried out indirectly the roll gap reference measurement, path length sensor or position sensor (6), I suggest that provided; (5b 5a) in the cylinder deflection of at least one of (1a, 1b) of the work roll.
