Description
The rotoforged product is an innovative product designed to finish even larger dimensions. The rotoforged product manages to combine the strengths of a rolled product and a forged product into a single large product.
As part of the development strategy, the Rotoforgia was installed and integrated into the Marte Line in 2015, after the Blooming 1000 with cooling bed (2014) and the new Reversible 800 mill with in-line finishing.

TECHNOLOGY
The ABS team and the Danieli Group have designed the largest long product rolling mill in the world: the Rf 1800 Stand: the Rotoforgia. The plant, which is one of a kind in the world, is programmed to process finished bars in the range of 400 – 500 mm rounds and 320 – 480 mm squares, or to produce a semi-finished product for both the Blooming 1000 and the Reversible 800 mills. With characteristics of high added value, the product obtained on this line combines a core condition that is equal to or not far from that of forged products and the surface quality of rolled products.
