Abstract
The invention relates to a method and a device for controlling the final thickness of a rolled product (B) at the outlet of a rolling mill including at least two roll stands (1–5) operating in tandem and associated with a general speed control system of the different stands, and to a device for controlling the reduction in thickness and in tension of the product (B) in each space (10–50) between two successive stands.According to the invention, the control device performs, in real time, dynamic balance, between the different stands (1–5), of the torques applied, in each stand, on the working rolls (T, T′), without any noticeable disturbance of the final thickness h5 of the product (B) at the outlet of the plant.The invention enables, in particular, to optimise the productivity of a tandem rolling mill, without any engine overloading risks.
