 Products

  • Forged Back-Up Rolls
    We produce back-up Rolls from 20/25 tons up to 250 tons finished weight thanks to our integrated cycle: form ingot to the forging all in the same area....

  • Our back up rolls are made by starting form a very clean steel due to the use of selected scrap coming from internal production and through from car indutries which allow us to have low level of S (0.002) and P (0.007). By using Under Vacuum degassing we reduce H content to less than 1 ppm. By using the big press of 12600 Tons we guarantee an optimal micorstructure due to the big deformation we can give to the forging and by using a rotative furnace for the DQHT of only the barrel we can guarantee a good uniformmity of Hardness values on all the length of the barrel and can manage the working layer depth according to the customer need.
