The Wire

High speed multi pass wet wire drawing has become very common for production of high carbon steel cord because of the increase in customer demand and production rates in real industrial fields. Although the wet wire drawing is preformed at a high speed usually above 1000 m/min, greater speed is required to improve productivity. However, in the high carbon steel wire drawing, the wire temperature rises greatly as the drawing speed increase. The excessive temperature rise makes the wire more brittle and finally leads to wire breaks. In this study, the variations in wire temperature during wet wire drawing process were investigated. A multi pass wet wire drawing process with 21 passes, which was used to produce steel cord, was redesigned by considering the increase in temperature. Through a wet wire drawing experiment, it was possible to increase the maximum final speed from 1000 m/min to 2000 m/min.

Drawing Speed

High speed wet wire drawing has become very common for the production of fine high-carbon steel wire (up to 0.70wt%C) because of the increase in customer demand and production rates in real industrial fields. Although the wet wire drawing process is performed at a high speed usually above 1000m/min, greater speed is required to improve productivity. However, in the high-carbon steel wire drawing process, the wire temperature rises greatly as the drawing speed increases. The excessive temperature rise makes the wire more brittle and finally leads to wire breakage. Therefore, the control of wire temperature is very important. In this study, the variations in wire temperature during the high speed wet wire drawing process were investigated. A multi-stage wet wire drawing process with 21 passes, which is used to produce steel wire, was redesigned by considering the increase in temperature. In order to apply the redesigned pass, a new wet wire drawing machine was developed. Through a wet wire drawing experiment with the new drawing machine and the redesigned pass, it was possible to increase the maximum final drawing speed to 2000m/min without the deterioration of the qualities of drawn wire.

The Wire

Recently, high-speed drawing has become very common because of the increase in customer demands and production rate in real industrial fields. In the high-carbon steel wire-drawing process, the wire temperature rises greatly according to the increase in the final drawing speed. The rapid temperature rise makes the wire more embrittled and finally leads to wire breakage. Therefore, in this paper, an approximate wire temperature estimation method is proposed to control the maximum temperature rise in the wire-drawing process. Using these results, it is possible to develop the isothermal pass schedule programme, to design the wire-drawing process. Also, the conventional pass schedule can be redesigned by considering the pass schedule constraints. As a result, the wire temperature was considerably reduced and the productivity of the final product could be improved by about 11 per cent.

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.

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.

Drawing Speed

In this work the influence of the drawing speed on fatigue strength of high carbon steel wires has been assessed. The drawing process of φ5.5 mm wires to the final wire of φ1.6 mm was conducted in 11 passes, in industrial conditions, by means of a modern Koch multi-die drawing machine. The drawing speeds in the last passes were: 5, 10, 15 and 20 m/s. For φ1.6 mm wires the investigation of fatigue strength has been carried out. In order to explain the effect of drawing speed on fatigue strength of rope wires, the roughness of drawn wires have been also determined. In addition, the numerical analysis of the drawing process on the base of Drawing 2D in which distribution of redundant strain, has been shown. The data of investigations prove the favourable effect of high drawing speed on fatigue strength of drawn wires. It was found that the better fatigue strength of wires drawn at the speed of 20 m/s compared to the wires drawn at the speeds of 5-15 m/s is associated with a better geometric structure of the surface of those wires. In addition to the high fatigue strength of the wires drawn with high speed is related to theirs higher redundant strain. The obtained data investigation can be applied in wire industry while implementing the new technologies of high speed drawing process of high carbon steel wires.

Abstract In this work the analysis of the wire drawing process in hydrodynamic dies has been done. The drawing process of φ5.5 mm wire rod to the final wire of φ1.7 mm was conducted in 12 passes, in drawing speed range of 5-25 m/s. For final wires of φ1.7 mm the investigation of topography of wire surface, the amount of lubricant on the wire surface and the pressure of lubricant in hydrodynamic dies were determined. Additionally, in the work selected mechanical properties of the wires have been estimated. It has been shown that in the drawing process under hydrodynamic lubrication by drawing speed of 25 m/s the phenomena of uncontrolled formation of the surface and the diameter of the wire appears, and in the process the compressive stresses eliminating cracks on the wire surface occur, causing further smoothing. The wires drawn hydrodynamically in speed of 25 m/s, besides clearly worse properties compared to the wires drawn hydrodynamically at speeds in the range of 5 to 20 m/s, also exhibit large dimensional variations.

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.
