Danieli patented the Twin Drum as the 120th technology solution for the long product rolling. This system integrates Twin Channel technology with a roller table featuring aprons, enabling the transfer of bars ranging from 8 to 40 mm in diameter into the cooling bed at speeds of up to 60 m/sec.
Danieli will modernize the main section of the bar mill’s finishing area at Marienhütte in Graz, Austria, installing a Twin Drum system to replace conventional aprons. The upgrade also includes a new cooling bed for bars up to 72 meters, replacing the existing 40-meter-capacity bed. The new equipment and automation will make the line will become fully automated.
The process will require less equipment, streamline operations, and improve operator safety. This upgrade will give Marienhütte greater production flexibility to adapt to changing market needs while reducing overall costs.
During a planned three-week shutdown, the turnkey project will involve disassembly, erection, and commissioning, targeting a start-up in early 2026.
