The effect of cold rolling parameters on the recrystallization texture of non-oriented electrical steel

The effect of cold rolling condition on magnetic properties of non-oriented electrical steel was investigated, For evaluation of cold rolling condition, utilizing rolling shape factor (RSP) was proposed, In the case of small RSF, magnetic induction was improved. Development of ND parallel to [111] components was suppressed in the recrystallized texture near the surface, and the vicinity of the {100}[001] component was developed after grain growth. The relation between RSF and cold-rolling condition was examined by computer simulation; such results were attributed to the increment of shear strain in the surface texture. Magnetic properties would be improved by adequate control of cold-rolling condition.
