Аннотация: The article presents the results of analytical and experimental investigations, as well as modeling of the ingotless rolling-extrusion (IRE) process for thermal deformation treatment of secondary waste of the extrusion production made of alloy 6063. Using the QForm software package and analytical calculations, the temperature–velocПоказать полностьюity and energy-force parameters of the IRE process for obtaining ligature rods with a diameter of 9 mm from waste of the investigated alloy were determined. In the course of experimental studies pilot, lots of such rods were obtained. The process parameters for rods production by the IRE method were specified and investigations of their structure and properties were carried out. In this case, the melt temperature was 750 ± 10 °C; the temperature of the crystallized billet was 520 °C; the roll rotation frequency was 5 rpm; the strain during rolling was 50%. Rods obtained from waste from the extrusion production of alloy 6063 by the IRE method have a stable ultra-fine subgrain structure. Analysis of the properties in comparison with a rod obtained by hot extrusion revealed higher plastic characteristics and full compliance with the requirements of the standard in force at the production site.
