Abstract (en)
[origin: EP0476793A2] The invention relates to a rolling mill for stretching hollow blanks on a mandril. In order to keep the number of roll stands as small as possible and to achieve maximum stretching in a smaller number of roll stands without sacrificing quality, it is proposed that at least one universal-type main deformation stand (1) with adjustable rolls (2, 3) and a two-high finishing stand (6) arranged after the main deformation stand (1), and, if required, a driving stand (12) arranged ahead of the main deformation stand be present. <IMAGE>
