KOPPLINGSANORDNING FOR EN VALSGAP-REGLERANORDNING

摘要

The roll gap is feedback controlled in that the actual gap is detected, compared with a reference for formation of an error signal which in turn controls the relative position of the rolls. That feedback system is supplemented by augmenting the error by a signal that is directly proportional to the time derivative of the rolling force and of the stock width and inversely proportional to the force itself.
