Abstract :
The no.2 reversing mill installed in the cold rolling plant of the Wakayama steel works (Japan) is described. It has been built with the aim of ensuring high-precision strip gauge and flatness. It includes a fully digitized AC variable-speed drive system and advanced technology that improves gauge accuracy. The specifications and features of the mill are set forth, the characteristics of the electrical equipment are discussed, and the gauge control system is examined in more detail.<>
