THE EFFECT OF COLD-ROLLING PARAMETERS ON THE RECRYSTALLIZATION TEXTURE OF NONORIENTED ELECTRICAL STEEL

The effect of cold rolling condition on magnetic properties of non-ori ented electrical steel was investigated, For evaluation of cold rollin g 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 tex ture near the surface, and the vicinity of the {100}[001] component wa s developed after grain growth. The relation between RSF and cold-roll ing condition was examined by computer simulation; such results were a ttributed to the increment of shear strain in the surface texture. Mag netic properties would be improved by adequate control of cold-rolling condition.
