NON-ORIENTED ELECTRICAL STEEL STEET AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a non-oriented electric steel sheet comprising: 0.010 wt% or less of C (excluding 0 wt%); 1.5 wt% or less of Si (excluding 0 wt%); 0.5 wt% or less of Al (excluding 0 wt%); 0.6 wt% or less of Mn (excluding 0 wt%); 0.2 wt% or less of P (excluding 0 wt%); 0.005 wt% or less of N (excluding 0 wt%); 0.005 wt% or less of S (excluding 0 wt%); 0.005 wt% or less of Ti (excluding 0 wt%); and the remainder consisting of Fe and inevitable impurities, and to a manufacturing method thereof. At a grain boundary misorientation angle of 15 degrees or less, a volume fraction of a {100} group is higher than that of a {110} group. The present invention provides the non-oriented electric steel sheet having a loss of low wattage, a high magnetic flux density, and a high magnetic property in a low magnetic field; and the manufacturing method thereof.
