The first aluminium hot strip coil was rolled on the Elval Halcor high-performance production line at the Oinofyta plant near Athens.
In its Oinofyta plant near Athens, Greece, Elval Halcor S.A. has successfully rolled the first aluminum hot strip coil on its new finishing mill supplied by SMS group.
The new, four-stand finishing mill was installed downstream an existing reversing mill. With the new plant, Elval Halcor S.A can produce hot-rolled aluminum strip in thicknesses from 1.8 to 12.7 mm and up to a width of 2.6 m for a wide range of industrial applications.
High system flexibility of aluminium hot strip production at Elval Halcor
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 CVCplus (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 CVCplus, work roll bending and work roll cooling systems while thickness control is accomplished via hydraulic adjustment systems.
Advanced rolling technology of SMS group
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.
Caused by the Covid-19 pandemic, Elval Halcor S.A and SMS group had to face particular challenges in the assembly and commissioning phase. But despite strong external limitations, SMS group managed to successfully finish final assembly and cold commissioning.
