【 摘 要 】

Drawing in monolithic dies is the basic operation of wire manufacturing. Despite the obvious advantages the drawing in monolithic dies is characterized by relatively tough stress-strain scheme of the processed wire which results in decreasing of its plasticity. During alternate drawing the wire goes through the conical die after which the drawing direction is changed. The results of investigation of alternate drawing process of medium carbon steel wire with 0.5 %C are presented in the paper. After simulation in software Deform-3D it was stated that strain intensity distributes uniformly across the wire transversal cross section. Using coordinate grid method the data about the metal flow both at traditional and alternate drawing was obtained. Results of carbon steel wire mechanical properties investigation proved the advantages of alternate drawing process. After alternate drawing the medium carbon steel wire possesses high plasticity at the same level of strength properties as compared with traditional drawing process. At the same time there were no considerable changings of medium carbon steel microstructure after alternate drawing.
