1. In a high speed wire rod mill line having a roll-stand group including a plurality of roll stands and outputting wire at a speed of 60 m/s to 130 m/s, the improvement wherein
the roll stands are spaced at between 800 mm and 1000 mm,
each roll stand has at least one pair of rolls or pair of roll rings,
each roll stand has its own drive with a respective motor and a respective drive shaft for rotating the respective pair of rolls or roll rings at a respective angular speed,
the motor, the drive shaft and the pair of rolls or pair of roll rings of each roll stand are aligned in a respective straight line with one another, and
the motors of the roll-stand group are all connected to a common controller that synchronizes the angular speed of each roll stand dynamically with the angular speed of at least one adjacent roll stand with respect to longitudinal tension and pressure in such a manner as to suppress resonance vibration.
