PURPOSE:To stably form with good yield a unidirectional electromagnetic steel plate having low iron loss and consisting of crystal grains having an azimuth represented as (110)[001]by Miller indices by a method wherein a specific amount of P is contained in a silicon steel material containing C: 0.020-0.080%, Si: 2.0-4.5%, Mn: 0.04-0.10%, S: 0.015-0.033%. CONSTITUTION:P of 0.013% or less is contained in a silicon steel material including C: 0.020-0.080%, Si: 2.0-4.5%, Mn: 0.04-0.10%, S: 0.015-0.033%, and a unidirectional electromagnetic steel plate having superior magnetism is formed by the secondary recrystallization phenomenon. The lower content of the above P makes better iron loss and a content of 0.013% or less remarkably improves the iron loss. |
