摘要

The objective of this study is to determine the feasibility of using experimental equipment in a continuous casting-rolling-pressing process to produce rods from hot-pressed aluminum alloy AD31 scrap. Values of the main temperature-, speed-, and energy-force characteristics were obtained by modeling the process with QForm software. This enabled the determination of the forces acting on the rolls and die, as well as the torques on the rolls and the power of the SPP-200 combined processing unit drive motor. A comparison of these values with the allowable values of the existing equipment revealed that the combined casting-rolling-pressing process can be implemented without overloading the equipment. Additionally, the modeling data can be utilized in designing and assembling the experimental combined processing unit, SPP-200. Experimental studies on producing 9 mm diameter rods from a melt obtained from an electric mixer furnace using scrap profiles of the AD31 alloy were conducted on this unit. The mechanical properties of the rods were determined, and it was found that they meet the requirements of GOST 21488-97 for such products. The energy-force characteristics of the applied unit were measured, and it was determined that the power of its drive motor does not exceed the allowable load.
