Comparison of Heating Systems for Aluminum Forging

One of the areas where the AA6082 alloyAlloys is widely used is the production of forgingsForgings for automotiveAutomotive suspension parts. Round profiles produced by extrusionExtrusion from AA6082 alloyAlloys are semi-finished products for forged part manufacturers. EN AW 60826082 aluminumAluminum extrusionExtrusion production profiles with a diameter of 45 mm and a length of 100 mm were used for the hot forgingForgings process. According to the result, the measuring system reached a maximum temperature of 637 °C. The 2 °C difference between the oven temperature and the measuring system is acceptable. It was observed that there was a maximum difference of 5 °C between the core and surfaceSurface temperatures of this sample, which was heated in a resistance laboratory furnaceFurnace. However, in the induction system there is a difference of about 50 °C. The difference affected the structure and the hardnessHardness between the core and surfaceSurface of the forgingForgings parts.
