Исследование влияния режима деформации на макроструктуру заготовок

Abstract

A mode of rolling bars with the mass of 3.6 tons made of steel 12Cr18Ni10Тi in 17 passages was offered. This method was developed by the program of calculating rolling modes of automated control system taking into account received mathematical models of distribution of level of plasticity reserve that allows reducing the number of passages by 2 and lower the average value of plasticity reserve level by 11 % compared with drafting patterns currently used on bars. This leads to the decreasing of defects in rolling production.
