Аннотация
This study includes the screw rolling of several blank parts of 12Kh18N10T steel on a two- and a three-roll mill, followed by modeling test rollings in the DEFORM FEM software. The test rolling results were used to evaluate changes in the dispersion of average grain size and hardness in the nonstationary and stationary phases of screw rolling. The computer-aided modeling results were used to evaluate variations in strain effective. The studies allowed identifying the changes in the average grain size and hardness in the different rolling phases and defined the compliance with the kind of changes in the average grain size, hardness, and strain effective across the blank part volume. The computer-aided modeling and test evaluation showed the differences in the kind of strain effective variations in the nonstationary phase at two- and three-high rolling.
