1. A rolling facility is provided with:

  • 2 coiling furnaces;

    a plurality of rolling stands arranged between the 2 coiling furnaces for reversible rolling;

    an induction heating device which is provided between the plurality of rolling stands and performs a specific heating temperature rise or performs heating temperature rise in the longitudinal direction and the width direction of the steel sheet in each reversible rolling;

    at least two tension rollers arranged in front of and behind the induction heating device between the plurality of roll stands; and

    a synchronous lifting mechanism for changing the height direction position of the two tension rollers and setting the height of the induction heating device and the height of the two tension rollers synchronously,the synchronous lifting mechanism controls the heights of the two tension rollers and the induction heating device, so that stable tension control between the rolling stands is implemented, and temperature rise by the induction heating device is easy.
