A secondary recrystallization Lab study focusing on the secondary recrystallization temperature and magnetic properties was carried out on cold rolling industrial samples of 3%Si grain-oriented electrical steel produced by low slab reheating temperature technology. The results showed a secondary recrystallization temperature, determined by the observed grain size change, of 1080 °C with annealing interruption and of 1060 °C in annealing for 50 h at constant temperature. In addition, the best set of magnetic properties, the higher induction and the lower core loss values, was achieved by annealing the samples during 50 h at 1070 °C constant temperature.
