Abstract
This article examines one of the main methods for speeding up the production of cold-rolled tubes, which entails performing the rolling operation without intermediate annealing. A previously developed software package is used to analyze the main factors in the technology in order to find an efficient schedule for such rolling. Results are presented from a study of mechanical and plastic properties of tubes rolled by two variants, and it is shown that the rolling operation is unstable due to broad scatter of the plastic properties of the hot-rolled billets. It is best to roll tubes without intermediate annealing after their mechanical properties have been checked. Technological recommendations are given on the conditions for rolling stainless steel tubes without intermediate annealing.
