Marcegaglia Ravenna revamped the strip cooling by ambient air in galvanizing line Nr.4

Marcegaglia Ravenna, in order to increase the production capacity of the existing continuous galvanizing line, revamped the strip cooling by ambient air in galvanizing line Nr.4, in cooperation with Prisma Impianti.

The new cooling system features a very simple design of the steel surfaces facing the strip, performing a significant decreasing of the manufacturing costs.

The lower air flow of the cooling fans reduces the size and weight of the conveyor ducts, with a lower absorption of energy.

The plant brings a significant reduction of the zinc coating defects (about 70%), with an electric energy saving of 20% of the total line consumption.
