Abstract: By sampling the head, middle, and tail sections of 50W600 non-oriented silicon steel, the causes of magnetic property variations were analyzed through grain size and texture evolution. The results demonstrate that grain size is the primary factor influencing iron loss in nonoriented silicon steel. Due to the larger average grain size in middle section samples and smaller grains in head/tail sections, the middle section exhibits lower iron loss compared to higher values in head/tail regions. The increased proportion of favorable textures {100} and {110} enhances magnetic induction intensity. Middle section samples show stronger magnetic induction owing to their higher content of {100} and {110} textures, while reduced proportions of these textures in head/tail sections result in lower magnetic induction.
