Introduction of continuous horizontal casting of billets at non-ferrous metallurgical plants raises the question of how to improve their subsequent deformation. Among the most efficient methods is batch rolling with high degrees (to 95 percent) of single deformation processes [1]. In order to reduce metal losses and produce a high-quality surface that kind of roiling is conducted in 3 cold state, with high loads on parts of the operating mill; the elastic deformation has to be calculated when working out the parameters and optimizing the rolling process. Calculations are complicated by the fact that under batch rolling, partial reductions and other parameters depend not only on strip thickness in these cross sections but also on the profile of the already rolled parts of the billets (intermediate sections) and the amount of linear shift for the metal.
