Abstract
The issue of improving the production efficiency and competitiveness of high-carbon steel wire, determined by a rational ratio of quality and costs of its production, is an urgent task. The main way to solve it is the development and implementation of an effective technical process, the main elements of which are the technological process and equipment for its realization. Since the middle of the last century, domestic steel wire production has been operating on imported equipment, which significantly hampers the use of modern technological processes. This unfavorable situation has been aggravated at present by the imposition of severe economic sanctions by “unfriendly states”. The way out of this situation in the current production is the improvement of existing and introduction of new methods of wire drawing. According to the original methodology the analysis of the existing at one of the domestic enterprises route of drawing of high-carbon wire rope wire with a diameter of 1.70 mm from wire rod of 5.50 mm with the use of standard single monolithic fibers, twin monolithic fibers, roller fibers, as well as modules including roller and monolithic fibers (combined drawing) was carried out. The obtained results have shown that when using standard fibers, the drawing route should be designed with the minimum possible multiplicity, which will provide on the existing equipment to improve the quality of wire and reduce the cost of its production. The greatest efficiency is provided by the application of combined drawing: twofold reduction of drawing multiplicity, energy saving up to 30%, improvement of wire quality by creating a favorable stress-strain state when deforming the wire first in roller and then in monolithic drawing. In addition, in comparison with the roller fibers, the equipment is simplified and the costs of its purchase and operation are reduced. Recommendations on the directions of increasing the efficiency of production in the conditions of existing production, purchase of new imported and designing of domestic drawing equipment are given
