Abstract
In this work the influence of the drawing speed on surface topography of high carbon steel wires has been assessed. The drawing process of f 5,5 mm wire rod to the final wire of f 1,7 mm was conducted in 12 passes by means of a modern Koch multi-die drawing machine. The drawing speeds in the last passes were: 5, 10, 15, 20 and 25 m/s. For final wires f 1,7 mm the three-dimensional analysis of the wire surface topography investigation was determined. It has been proved that the wire topography in the drawing process is characterized by a random anisotropy and the amount of directing the geometrical structure of the surface depends on the drawing speed.
