Zusammenfassung:	PURPOSE:To efficiently produce an extremely thin strip of low-loss directional silicon steel by subjecting an extremely thin intermediate strip obtd. by cold rolling of a directional silicon steel strip stock having a specific silicon content to a specific high-temp. heat treatment in a nonoxidative atmosphere or reduced pressure atmosphere. CONSTITUTION:The directional silicon steel strip stock having (110)[001] crystal grain texture and contg. 2-8wt.% Si is cold rolled to obtain the extremely thin intermediate strip having
