Abstract

Improvement of quality and production volumes of steel ropes widely used in almost all fields of industrial production and being a product of high-level conversion in the metalware process stage of iron and steel industry is a crucial task in modern economics. The main indicators of rope quality are mechanical and fatigue resistance values, which are determined by the corresponding index of the layer wire. Formation of strength and fatigue parameters of high-carbon steel wire during its drawing in monolithic dies is determined by strain modes implemented in specific drawing sequences. The main indicators of the latter are the degrees of total and unit (drawing rate) strain. It is generally accepted that the strength of the finished wire is determined by the total degree of strain and does not depend on the unit strain degree. The effect of the unit strain degree on the drawing process performance (costs, stability, time), non-uniformity of strain and the nature of the stress state of the wire has been investigated. However, the effect of a single draft on the wire fatigue resistance has not been sufficiently investigated. Experimental studies on drawing of a 3.80 mm diameter patented billet in sequences with average draft values of 22.0, 25.0 and 29.0 %, carried out for this paper, have shown that with the increase in the single draft value, the values of strength (linear dependence) and fatigue resistance (exponential) increase and the number of kinks decreases. By modeling in the Deform-3d software package it was found that the difference in mechanical and plastic properties of the finished wire is greatly influenced by the non-uniformity of the accumulated degree of strain in the cross-section of the wire between its center and surface, which leads to the formation of a certain gradient. The paper presents calculations of the accumulated degree of strain gradient value during drawing in five-, six- and seven-fold drawing sequences. Recommendations are given on the methodology for calculating of drawing sequences.
