Rolling Mill Speed Calculation Formula

Value Paper Authors: SUN Xin, SUN Han-feng Speed cascade .

Speed cascade control is the most important part of the control system for modern profile mills. Since the distance between the stands is short and the rolling speed is fast, the control system must have high accuracy, good stability, fast speed regulation and self-adaption. Precise material tracking is the base for .
