Abstract

An unoriented silicon steel having high magnetic conductivity and low iron loss at a working magnetic density of 1.0 1.5 T and method for manufacturing same. By proper deoxidation control in a RH refining and high temperature treatment for a short time in a normalizing step the method can reduce the amount of inclusions in the silicon steel and improve grain shape so as to improve the magnetic conductivity and iron loss of the unoriented silicon steel at a magnetic density of 1.0-1.5 T.
