Process for operating a stretch reducing mill for rolling pipes comprises: determining a time point at which the rear end of the pipe leaves the roll stand in the conveying direction; establishing a time interval at which the rear end of the pipe leaves the roll stand, and controlling and regulating a drive of the roll stand. ??Process for operating stretch reducing mill for rolling pipes comprises: determining a time point at which the rear end (8) of the pipe (2) leaves the roll stand (3d'''') in the conveying direction; establishing a time interval of a prescribed duration in which the time point lies and at which the rear end of the pipe leaves the roll stand; and controlling and regulating a drive (7'''') of the roll stand, so that the rollers of the roll stand are driven at a constant speed during the duration of the time interval. ??An Independent claim is also included for a stretch reducing mill for rolling pipes. ??Preferred Features: A tolerance is given for controlling and regulating the drive of the roll stand and is not exceeded. A sensor (10) is arranged in front of the roll stand for acquiring the time point when the rear end of the pipe passes the sensor.
