The numerical model following the equivalent magnetic domain method is proposed to calculate the anisotropy of the magnetic properties of electrical steel. The angle difference between magnetic flux density vector and magnetic field vector, which is observed in the measurement data, is clearly expressed by the proposed model. The angles characteristics of stepwise or lamped shape are shown to be consequences of the strong magnetic anisotropic property.Index Terms-Angle difference, anisotropic steel, finite-element method, magnetic field vector, magnetic flux density vector, rotational magnetic field.

“…Therefore, a single inhibitor by MnS is usually used to prepare common grain-oriented silicon steel. AlN particle is usually used to produce high-magnetic induction oriented silicon steel using inherent or acquired inhibitor method 19,20) as its strong inhibition 21,22) . In the inherent inhibitor method, the AlN particle is mainly derived from the precipitation in the normalized stage 7) .…”

In this paper, 0.18 mm thin-gauge S-type steels with MnS and N-type steels with AlN as main inhibitors, respectively, were fabricated using three different nal annealing systems. Moreover, the evolution behavior of the MnS and AlN [(Al, Si)N] particles and grain orientation were investigated. Number density and mean diameter of second-phase particles were statistically determined by eld-emission scanning electron microscopy. Results indicated that evolution of MnS and AlN would be suppressed with increased N 2 content during annealing. The onset ripening temperature of MnS was lower than that of AlN particle, which caused secondary recrystallization in the S-type samples at lower temperature compared with that of the N-type samples. Moreover, for the N-type steel fabricated by nitriding method, the effective inhibitor was (Al, Si)N formed by the decomposition of (Al, Mn, Si)N. The decomposition of (Al, Mn, Si)N particles and coarsening of (Al, Si)N inhibitors were strongly inhibited and delayed with increased N 2 content in annealing atmosphere. In conclusion, N 2 /H 2 ratio of annealing atmosphere could be an effective control parameter to enhance the inhibition ability and delay secondary recrystallization onset in forming sharp Goss texture.

“…In the preparation process of oriented silicon steel, the final purpose is to obtain {110} <001> texture (goss texture) which causes the excellent magnetic properties and low iron loss [1][2][3][4][5][6]. The high component of Goss texture is the key factors to obtain the high magnetic and high stability of the finished product [7,8]. In the process of preparing the Goss texture by the secondary recrystallization method, the metastable second metastable phase in the matrix plays a key role, and these precipitates will effectively inhibit the growth of non-Goss orientation grains during the secondary recrystallization annealing process, And thus improve the composition of Goss grains, usually we will define these precipitates as inhibitors.…”

The as-cast microstructure of niobium-containing slab was observed and characterized by metallographic microscope and scanning electron microscopy. The results show that the as-cast microstructure of the niobium-containing silicon steel slab is ferrite and a small amount of pearlite. There is no obvious difference in the microstructure of the niobium-containing silicon steel slab, and the as-cast (Cu, Mn) S, in addition to niobium carbon, nitride precipitation, AlN mainly strip and square, sulfide and niobium carbon, nitride was mainly Spherical or ellipsoidal. The number of precipitates in the slab is small but larger in size, and the size of precipitates is in the range of 100 nm to 500 nm.
