Abstract
A controller () and method for controlling a stretch-reducing mill () for rolling tubes are presented. The stretch-reducing mill () has several roll stands () arranged behind one another in a conveying direction (F) of the tubes (R) and at least one outlet-side wall thickness measuring device (). The controller () is set up to receive measurement data from the wall thickness measuring device () which identifies one or more outlet-side wall thicknesses (s) of a tube (R) exiting from the last roll stand () and one or more of the received measurement data wall thickness on the inlet-side (s), preferably to determine an inlet-side wall thickness profile of the tube (R) before entering the first roll stand (), and preferably to calculate and control one or more of the roll stands (), taking into account the determined inlet-side wall thicknesses (s).
