This work considers the results of modelling the stress–strain state of the wire in the implementation of a new thermomechanical processing technology, which is a combined process of drawing and continuous cooling in a special chamber using liquid nitrogen. The absence of heating to ambient temperature causes an increase in the level of equivalent stress by 5−10%. An increase in the deformation rate causes a decrease in the stress level due to an increase in deformation heating. The development of cross-sectional strain occurs unevenly, the surface receives a higher level of strain. As the number of passes increases, this difference increases due to the cumulative nature of the equivalent strain.
Key words: modelling, steel, wire, drawing, cryogenic cooling, stress–strain state.
