Abstract
A method is proposed for determining the unit work of deformation in the broaching of blanks in two-roller screw-rolling mills. A new approach is outlined for assessing the fracture risk and the structure of continuous-cast circular billet. Methods for determining the work of deformation in different sections of the deformation zone are considered. The distribution of the work of deformation due to reduction over the whole deformation zone is determined. The influence of extension on the work of deformation is assessed for similar rolling mills at OAO Pervoural’skii Novotrubnyi Zavod and OAO Yuzhnotrubnyi Zavod.
