Rolling Speed during Flying Gauge Change for Tandem Mill and Rule of Volume Flow Rate

The relationship between speed and tension was analyzed theoretically. The speed balance and rolling tension during continuous rolling were studied. It was recognized that steady continuous rolling may be sorted into independent mill rolling with tension, but the tension and speed of stack must be identical to that in front and back frames. When the gap of rolls changes with tension, with the tension, there is a transition steady period of the cross section change of rolling stack between the frames, while the speeds of the cross sections are equal, but the theory of volume flow equality should not be used.
