In this paper, the evolution of texture in the ferrite phase and mechanical behavior of cold-drawn pearlitic steel wires produced for strand manufacturing at Trefisoud company was investigated. Wire drawing induces the development of dislocation density, reduction of interlamellar spacing and the refinement of grains size which leads to a strong hardening of the wires. That explains the increase of the tensile strength from 1242 MPa to 2618 MPa with higher deformation. Also, the cementite lamellae are rotated toward the drawing axis and the thickness of lamellae further decreases when strain level increases, this phenomenon leads to a somewhat fibrous structure. The quantitative analysis obtained by EBSD data shows the development of a strong (<110> // ND) texture of the ferrite phase leading to a structural transformation from isotropic to anisotropic.

Optimal Value

In this work the influence of value of single draft on mechanical-technological properties of high carbon steel wires was evaluated. For wires drawn with medium single draft (10.4 %, 15.5 % and 26.5 %) the investigation of mechanical-technological properties was performed thereby providing results on yield strength, tensile strength, elongation, contraction, number of twist and number of band. On the basis of numerical analysis of wire drawing process the influence of the value of single draft on inhomogeneity of strain was determined. It was established that in the range of medium single drafts 10-26 % used in drawing process of high carbon steel wires large single drafts cause the increase of their strength properties by deterioration of their plasticity properties. It was demonstrated that the increase of strength properties in wires drawn with larger single drafts is related to the occurrence of higher non-dilatational strain, which cause additional work hardening of material. The theoretical-experimental analysis of drawing of high carbon steel wires enabled evaluation of optimal value of single drafts by which it can be used relatively the most advantageous useful properties of wires. Obtained research results can be applied while designing the production process of high carbon steel wires.

The Wire

Cold-drawn high-carbon steel wire with pearlite microstructure is one of the most popular raw materials for modern reinforcing ropes. Lamellae thinning, changes in interlamellar interface and metallographic texture, strain localization is the main property-forming phenomena in the wire drawing process. However, the experimental study of these phenomena dynamics is difficult and time-consuming. Drawing process of pearlitic steel wire was investigated. Behavior of pearlite colonies on the surface and the central layer of the wire were researched, based on the multiscale computer simulation. Cementite lamellae orientation in relation to the drawing axis, interlamellar spacing and shape of cementite inclusions were key factors. Regularities of the pearlite colonies reorientation, changing the shape and size of cementite lamellae and strain localization in the ferrite were established on the basis of FEM. It was established that the cementite lamellae, that are parallel to the drawing axis, had the maximum thinning. Interlamellar distance in pearlite colonies with such lamellae changed most intensively. Cementite lamellae, that are perpendicular to the drawing axis, are the most susceptible to fracture. It was found out that for certain values interlamellar distance this effect can be reduced. Intensive reorientation of pearlite colonies in relation to the drawing axis was observed in the case of their location at an angle to the drawing direction. At the same time, there was a significant bending of cementite lamellae and their susceptibility to fragmentation. Estimated values of the wire mechanical properties were compared with a real experiment. The simulation results were verified by metallographic analysis.

Good Agreement

This paper presents simulations of the texture development during cold rolling of fully pearlitic steel. In order to investigate the importance of including microstructural aspects into texture simulations the calculations were carried out with the FC Taylor Pearlite model which takes the lamellar microstructure into account and with the FC Taylor and LAMEL model which are dedicated for one phase materials. The results are compared with those for ULC steel. For both materials the LAMEL model results are in good agreement with experimental data, while for the pearlitic steel, the FC Taylor Pearlite model improves the predictions only slightly with respect to the FC Taylor model.

Drawing Method

High carbon steel wires, due to their high mechanical strength and high fatigue characteristics, have been widely used in industrial products such as bridge cables and steel cords for tires. To produce wires that match the requirements for those purposes, wire drawing process is used. However, after the processing, tensile strength of the wires increases, but ductility decreases due to the shear deformation near the wire surface. In this study, we examined ductility improvement methods of high carbon steel wires and as a solution we suggest a method of processing called “alternate wire drawing”. The next step was to determine the usefulness of alternate wire drawing for increasing the ductility of the wires. Firstly we studied the total equivalent strain and the change of the shape of elements for each drawn wire by FEM analysis before testing. It was determined that in the case of alternate drawn wire the deformation of the elements was small also alternate wire drawing method is inhibiting the increase of total equivalent strain on wire surface. In case of tensile testing of drawn wire, we examined the mechanical properties of each wire drawing method and compared them. By doing this test we understood that in the case of alternate drawing there is a significant increase of breaking strain and drawing rate. We also have done torsion test to confirm the ductility of conventional wire drawing and alternate wire drawing. In case of conventional wire drawing method (Total reduction 91.7%) delamination appeared, however alternate wire drawing method (Total reduction 91.7%) there was no delamination. In addition, in case of total reduction of 97.2%, alternate drawn wire increases 20% more its torsion characteristics, than conventional drawn wire. And we also studied the changes of the crystal grain of drawn wire by EBSD (Electron Back Scatter Diffraction Patterns). We found out that grain size was shrunk by conventional drawn wire due to share deformation and for alternate drawn wire we confirmed that it was possible to inhibit the grain shrinking by 15% compared to the conventional drawing method. As a conclusion we found out that, by using alternate wire drawing method it is possible to improve the ductility of high carbon steel wires with the high tensile strength.

Bearing Part

In this work the influence of the die approach and bearing part of die on mechanical-technological properties of high carbon steel wires has been assessed. The drawing process of φ5.5 mm wires to the final wire of φ2.9 mm was conducted in 6 passes, by means of a multi-die drawing machine Koch type. The drawing speeds in the last passes were: 7 m/s. For wires drawn according to four variants the investigation of mechanical-technological properties has been carried out, in which yield strength, tensile strength, uniform and total elongation, reduction of area, the number of twists and the number of bends were determined. On the basis of numerical analyses wire drawing process, the influence of geometry of die on redundant strain and effective strain has been determined. The investigations have shown the essential influence of geometry of die on mechanical-technological properties of high carbon steel wires. It has been shown that the increase of strength properties in wires drawn with high die angle is related to the occurrence in their bigger effective strain.

Multiparameter Analysis

The essential purpose of the work was to determine the phenomena that occur in multipass wire drawing process of high carbon steel wires with high speed in hydrodynamic dies and to assess their influence on moulding the wire properties after the drawing process. The multiparameter analysis of the issues has involved the theoretical dissection of the phenomena arising in high speed wire drawing process in hydrodynamic dies with the usage of the finite element method supported by the experimental multipass drawing process in industrial conditions. On the basis of numerical analysis the influence of drawing speed on wire temperature was estimated. For final wires the investigation of mechanical properties, topogrhaphy of wire surface, the amount of lubricant on the wire surface, the pressure of lubricant in hydrodynamic dies were determined.
