Abstract
A method for controlling the stretching of rolling stock, particularly of pipes, by way of a pilot control system for the rolling stock taking into consideration measured physical values of the rolling stock. In order to be able to adjust the pilot control system as accurately as possible, in addition to or instead of an optical temperature measurement, the temperature in the interior of the rolling stock is determined by an integral measurement of a physical quantity proportional to this temperature and is superimposed as a signal on the pilot control system.
