AI Technical Summary
Technical Problem
Current metal strip manufacturing processes face issues such as thermal energy dissipation into the environment, high investment in coil storage structures, and extended production times due to inefficient cooling methods, which impact delivery dates and environmental sustainability.
Method used
A metal strip manufacturing plant with a closed-loop system that recovers thermal energy from hot-rolled strips using heat exchangers and cooling rollers, converting this energy into electrical or thermal energy for reuse within the plant.
Benefits of technology
The system recovers approximately 75% of thermal energy, reduces carbon dioxide emissions by 60,000 to 70,000 tons annually, and shortens production lead time by 1 to 2 days, enhancing sustainability and profitability.

Abstract
A metal strip manufacturing plant comprising: a hot rolling mill (1) for manufacturing strips from castings; a cooling station (2) located downstream of the hot rolling mill (1) and having a first heat exchanger (22) for cooling the strips; a closed circuit (3) capable of supplying a first heat transfer medium, the closed circuit (3) having a portion passing through the first heat exchanger (22) and taking thermal energy from the strips to heat the first heat transfer medium; a second heat exchanger (23) cooperating with the closed circuit (3) to transfer thermal energy from the first heat transfer medium to a second heat transfer medium; and an additional closed circuit (5) capable of supplying a second heat transfer medium, the additional closed circuit (5) cooperating with the second heat exchanger (23) and configured to convert at least a portion of the thermal energy transferred to the second heat transfer medium into electrical energy and / or supply at least a portion of the thermal energy transferred to the second heat transfer medium to at least one user device.
