摘要

P process to finish rolling and rolling mill in order to obtain the finished products having the dimensional differences are reduced. / p & & p & the process according to the present invention provides for the passage of the starting product through three rolling stands 16, 17, 18 whose cylinders are, respectively, horizontal - - vertical, horizontal, vertical, horizontal or vertical - -, arranged in this order in the direction of the reduction, in order to obtain a better precision of the dimensions of the finished product. The starting product has an oval section, it is rolled with the intermediate and lower, respectively, in the first and second ball cages which comprise a flute, oval, then it is then rolled to obtain a finished product with a small reduction in the third cage which comprises a corrugation round / p & & p & the process according to the present invention makes it possible to obtain products which are round, finished, the dimensional differences are reduced. / p
