ABSTRACT:
A cold rolling method for producing a high magnetic flux density grain oriented electrical steel sheet or strip having remarkably excellent B.sub.8 characteristics, comprising subjecting a hot rolled steel sheet or strip a combination of heavy cold rolling with annealing during which the steel sheet or strip is held at a temperature between 100.degree. and 350.degree.C at an interim sheet thickness stage during the heavy cold rolling.
