Roll eccentricity compensating system for rolling mills - with increased accuracy and speed of control action

摘要

Six parallel ring memory shift registers have their data inputs connected to input switches which are in turn connected to the output of an analogue-digital converter. The shift register outputs are connected to output switches connected in turn to the input of a digital-analogue convertor. Each first shift register data input is connected to the register output through a feedback and the shift timing inputs are connected to input to an angle gauge also connected to the input of a difference forming unit. The second input of the latter is connected to the input to a second angle gauge, and its output is connected to the input switches and the output switches.
