Using of Design of Experiments for Describing of Impact of Cold Drawing Process Parameters on Plastic Properties of Wire for Steel Ropes

Original language description

The present paper approaches the topic from two perspectives. The first one is a mathematical approach, using which various experimental designs will be compared. From the metallurgical perspective, the effects of various factors and their interactions on drawn wire properties will be explored. Shear deformation of subsurface layers in wire drawing leads to marked non-uniformity of strain across the wire cross section. In wires intended for products operating under dynamic loads, such as ropes and springs, the variance in work hardening level across the cross section may cause fatigue fractures. In this paper, we used physical modelling in an attempt to show how the non-uniformity of strain in drawing can be reduced by changing key process parameters. For this purpose, a full factorial experiment involving three factors was undertaken. (The factors included the approach angle 2α, single pass strain Qd or the number of passes n and type of scale removal (pickling or 2 axis bending + brushing.) The simulation involved drawing of 2.5 mm C78DP steel wire from 5.5 mm thick rolled rod. Koch single wire drawing block with a rotating die holder was used for the modelling. In this paper, we evaluate the influence of several factors on final plastic properties of the wire (number of torsion to fracture, number of bends to fracture). Tensile tests and metallographic analysis were also conducted.
