This work is concerned with the study of the emerging deformation forces during the implementation of a new method of thermomechanical wire processing that is a combined process including successive stages of wire drawing and cooling in a special chamber with liquid nitrogen. The analysis of forces is carried out by finite-elements’ modelling of the combined process within the DEFORM program. As found, the presence of intermediate heating to ambient temperature allows calculating the force according to the Krasilshchikov formula and the well-known nomogram of the tensile strength of AISI-316 steel at 20°C with minimal errors. The deformation without intermediate heating leads to the negative temperatures in the workpiece section in the second and third drawing cycles.
Key words: drawing, wire, modelling, steel, stress–strain state, cryogenic cooling.
