| Abstract Scope |
Non-oriented electrical steels require enhanced magnetic properties to minimize energy losses in automotive electric motors. This project introduces an alternative manufacturing method starting with steel produced from melting with the composition: C (0.022%), Si (2%), Al (0.66%) by weight. Following melting, homogenization and subsequent hot rolling produced 2.3 mm thick sheets. Intercritical annealing at 850°C with varying durations followed, succeeded by cold rolling to achieve 0.5 mm thickness, and final annealing at various temperatures and durations.
Modifications in the manufacturing process of this electrical steel resulted in favorable outcomes, including reduced energy losses attributed to improved textures. Furthermore, adopting this method promises significant reductions in the time required for final annealing compared to current industry standards. |
