Ultra-fine high-carbon steel wire drawing with ultrasonic vibration

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.

Abstract Use of computer programs based on finite element methods for simulations of plastic working processes allows for their wider analysis. The theoretical studies presented in the paper, carried out using Drawing 2D, a specialized software application for modelling of the multi-stage drawing process, and their experimental verification have enabled a comprehensive analysis of many problems related to high-carbon steel wire drawing to be made, such as: drawing under hydrodynamic lubrication conditions, drawing with a change in the deformation direction, drawing with small final reductions, and high-speed drawing.
