Fineiral Alumina Group in Sainte-Hermine, France installed and started up a new 23 MN, 8 inch T-Win extrusion press from Danieli Breda. The company operates Reinal, its branch specializing in powder coating, and Algis, its branch for logistics and distribution. Now, Fineiral Alumina has expanded its business into the extrusion market in order to provide integrated production with the new company, named Aluminia. This new press is the first of its kind in Europe, and will be the first of three lines that Aluminia plans to install in the future. The owners, Thierry and Regine Corre, signed a final acceptance certificate in February 2016.
The new press installed in Sainte-Hermine can extrude 8 inch by 1,200 mm billets and has an installed power of only 410 kW and a dead-cycle time of 9 seconds. With this new press type, the oil needed for each cycle is drastically reduced, improving the press performances and the energy savings by at least 30%. It also provides extended container life, since it is subject to less thermal stress. Continuous support and collaboration with Aluminia, alongside solid technical commitment made it possible to carry out installation and commissioning of the press in a strict time-frame.
This was Danieli Breda’s second order for the patented T-Win extrusion press technology, a design aimed at increasing productivity and improving energy savings. The double container concept enables, the next billet to be loaded outside of the extrusion axis during the extrusion phase; then, at the end of the extrusion phase, the twin containers are shifted laterally and the new extrusion sequence can start immediately.
According to Danieli Breda, when compared to a standard front-loading press with the same force range, the T-Win offers additional advantages: including, a reduction of installed power by 150 kW; a shorter dead-cycle time with slower movements, and therefore less hydraulic and mechanical stress; elimination of billet loader damage; a reduction of the container bore/billet diameter, which improves billet upsetting time by 40%; container parts typically subject to the highest thermal stress can be consistently cooled thanks to the double container layout; no risk of shear cylinder oil leakage on the profiles; the shortest recorded strokes worldwide thus less wear on sliding parts (for instance, billet dimensions of 250 mm with the 23 MN T-Win compared to 1,300 mm for the similar front loading model.
