Hot rolling mill aluminum, Elval (Greece)

Greek aluminum producer ElvalHalcor S.A. It is operating a high-performance hot finishing mill, supplied by SMS group. It is designed to produce aluminum hot strip for demanding applications. With the new plant, ElvalHalcor S.A can produce hot-rolled aluminum strip in thicknesses from 1.8 to 12.7 millimeters and up to a width of 2.6 meters.

In its Oinofyta plant near Athens, Greece, ElvalHalcor S.A. is operating a new hot finishing mill by SMS group since 2020. The four-stand finishing mill was installed downstream of an existing reversing mill. The aluminum hot strip being produced there is used for a wide range of industrial applications like can stock, automotive and marine etc.

Plant flexibility and the high quality of the rolled products are ensured by the advanced rolling technology of SMS group in connection with the X-Pact^® automation. In addition to CVC^® plus (Continuously Variable Crown) in all four mill stands, the profile and flatness system and the thickness control should be mentioned here. Also, the finishing mill is provided with an advanced roll and strip cooling system. It includes transfer bar cooling in the entry section and cooling devices in the interstand section. Profile and flatness control is ensured by the interaction of CVC^® plus, work roll bending and work roll cooling systems while thickness control is accomplished via hydraulic adjustment systems.

Within the scope of this project, AMOVA, a company of SMS group, supplied the complete coil transport system comprising four coil cars, two turntables, two cradle roller stations, one lifting table, two coil deposits and a fully automatic strapping machine for the circumference as well as a fully automatic combined machine for circumference strapping including weighing and marking.
