Abstract
The bimetallic wire manufacturing process involves two stages: the production of the blank (rod) and the fin-ished product (wire). Based on the research and development conducted at the Nosov Magnitogorsk Mining and Metal-lurgical Institute, scientists have developed a technology for producing steel-copper rod using solid-phase metal bond-ing and implemented it at one of the enterprises in Magnitogorsk. This technology has significantly improved the adhe-sion of the sheath to the core and the stability of the wire rod drawing process. However, the issue of reducing the cost of bimetallic wire production remains unresolved. Therefore, the calculation of an efficient drawing route is of great importance, as it should ensure the production of high-quality wire with minimal manufacturing costs. For the analysis, an existing route for producing wire with a diameter of 1.15 mm has been selected, which includes three processing stages and 20 drawing passes at one of the enterprises in Magnitogorsk. In addition, a proposed drawing route has been considered, developed using a methodology created at our university, based on the evaluation of the stress-strain state of the wire in the deformation zone. The calculation results make it possible to obtain wire of the required quality level with minimal energy and material consumption. An analysis of the existing and proposed drawing routes has showed that the latter ensures process stability (safety factor values remain below the limiting values), the required wire quality due to uniform deformation across the wire cross-section, and high productivity by increasing die life and reducing the total length of wire passing through the dies. At the same time, the number of drawing passes has been reduced by 7 (or 35%), and electricity consumption has decreased by 23%. This also leads to a 35% reduction in equipment purchase costs and depreciation expenses.
