ABSTRACT:
In a method of operating a tandem rolling mill, the speeds of the mill rolls are kept constant, a signal representing the mass flow of material entering the first stand is compared with a signal representing the desired mass flow of material leaving the last mill stand and the difference, if any, is used to control the load on the first stand in the sense to reduce the difference substantially to zero.
