MARIENHÜTTE TO REVAMP BAR LINE WITH NEWLY PATENTED DANIELI TWIN DRUM TECHNOLOGY
A single bar-delivery system for cooling beds, for bars ranging from 8 to 40 mm diameter
me-metals: Twin Drum is the 120th technology solution patented by Danieli for long product rolling.
According to me-metals cited from mining.com, It combines the technology concepts of Twin Channel and roller table with aprons, allowing the delivery of bars with diameters from 8 to 40 mm into the cooling bed at speeds up to 60 m/sec.
At Marienhütte works in Graz, Austria, Danieli will revamp the largest part of the finishing area of the bar line, and among other changes will install a Twin Drum system eliminating the need for conventional aprons. A new cooling bed will receive bars up to 72 meters of length replacing the existing one for bars up to less than 40 meters.
Thanks to the new equipment and automation the line will become fully automated.
The equipment required for the process will be reduced, operations will be simplified, and operator safety enhanced. The upgrade will provide Marienhütte greater flexibility in production to meet evolving market demands while lowering overall costs.
The turnkey project includes disassembly, erection, and commissioning activities during a planned, three-week plant shutdown. The start-up is scheduled for the beginning of 2026.
