ABSTRACT:
A rolling line for long products having a starting nominal transverse dimension between 120 and 180 mm and a final nominal transverse dimension between 4 and 25 mm. The rolling line comprises at least one roughing assembly, an optional reduction and sizing assembly, a fast pre-finishing assembly, and a fast finishing assembly. The optional reduction and sizing assembly having three rolling passes for finishing the long products when their final nominal transverse dimension is in a range between 20 mm and 25 mm. The fast pre-finishing assembly having a plurality of rolling passes, wherein the products are subjected to a same reduction sequence up to the last rolling pass of the plurality of rolling passes. The fast finishing assembly is provided for finishing the long products when their final nominal transverse dimension is lower than 20 mm and has four rolling passes comprised as two separate modules, each having two rolling passes. At least the fast finishing assembly and the reduction and sizing assembly are associated with a changing assembly for quickly changing equipment according to the required reduction of the transverse dimension of the long products. A method for rolling feedstock having a starting nominal transverse dimension between 120 and 180 mm to become long products having a final nominal transverse dimension between 4 and 25 mm. is also provided.
