VAI Reversing 4-Hi Cold Rolling Mil

1 reversing 4-Hi cold rolling mill

Mfc: VAI Revamped: 1998 Dismantled: 2008

Revamped in 1998 extent of revamp total change of electrical equipment,

new process control system, new automatic gauge control, new strip elongation control, installation of hydraulic roll gap setting system, both expanding mandrel reels changed

(including gear-boxes)

The Reversing Mill was carefully dismantled in 2008, cleaned as far as necessary, packed into 47 (40 FT) containers and transported to the storage area.

To the mill belong a great stock of spare parts and rolls. A nearly complete documentation exists.

The Reversing mill is in very good condition and can be used for production process within shortest term.
