The paper presents a study to determine the RAM speed and billet temperature to ensure that both the surface roughness of aluminum alloy bars and the extrusion pressure are the smallest. The RAM speed and billet temperature are the main parameters that influence the surface roughness and extrusion pressure when extruding aluminum bars. Product surface roughness is an important indicator of the quality of extruded aluminum alloy bars. Extruded pressure affects the machine’s performance and die life. By the theory of experimental combination, the authors built regression function showing the relationship between surface roughness, extrusion pressure with RAM speed and billet temperature. Using the optimization method of two indicators, the author has determined the RAM speed and billet temperature to achieve the surface roughness of the aluminum alloy bar product, where extrusion pressure is minimal. The results of this paper can be applied to determine the RAM speed and billet temperature in aluminum alloy extrusion factories. |
