This article discusses the findings of a study on ingotless rolling-extrusion process (IRE) for producing long deformed semifinished products from molten aluminum alloys with diverse chemical compositions. It highlights the benefits of this method compared to traditional extrusion technology, emphasizing reductions in labor intensity, energy consumption, and overall product costs. The research utilizes a combined processing unit featuring roll diameters of 200 and 400 mm. The alloys Al-Zr-Fe and Al–Mg-Sc selected for this investigation. Using the QForm software package for computer modeling, we analyzed the metal deformation throughout various stages of the process. We identified the processing temperature conditions while varying strain and strain rate parameters. The key process parameters established include a workpiece temperature of 550 °C after melt crystallization in rolls, die and roll temperatures of 200 °C, roll rotation frequencies of 4 and 8 rpm, and a relative rolling reduction of ε = 50%; drawing ratio μ = 4.4–14.3. Additionally, we calculated the values of the forces acting on the rolls and die, the torques on the rolls, and the power of the drive motors for the presented units. Pilot batches of rods and wire made from Al-Zr-Fe and Al–Mg-Sc alloys produced under industrial conditions using the CRE-400 unit and the IRE method. These products meet international standards.
