ABSTRACT:
A process for manufacturing a high magnetic flux density grain oriented thin electrical steel sheet having superior magnetic properties and for use on transformers is disclosed. Proper amounts of Sn, Cr, Ni and Mo are added into a high magnetic flux density grain oriented electrical steel sheet in which AlN and MnS are utilized for inhibiting the growth of the primary recrystallization grains. The process results in the production of a high magnetic flux density grain oriented thin electrical steel sheet showing a stabilized recrystallization, a high productivity and a high yield.
