The article presents the results of research that make it possible to solve a significant scientific problem associated with the creation of new technologies for processing hard-to-deform aluminum-silicon alloys. For this purpose, tasks were set and solved for the development of technological schemes for obtaining longish products from AlSi12 and AlSi5 alloys using the methods of electromagnetic crystallization ingots of a small cross-section and the manufacture of deformed semi-finished products in the form of rods and wire using the method of combined rolling-extrusion (CRE) and drawing. To solve these problems, the modeling of the CRE process, theoretical and experimental studies were carried out, the results of which made it possible to obtain pilot batches of welding wire from the AlSi12 alloy, the level of properties of which meets the requirements of current standards. To analyze the combined rolling-extrusion, modeling was carried out using the DEFORM 3D software package. Regularities were established for changing the temperature-rate and force parameters of this process along the deformation zone. Since the use of the proposed technological scheme for the combined processing of aluminum-silicon alloys leads to a decrease in labor intensity and production costs, it can be recommended for use in industry to obtain longish products from them. |
