Fe-3.10%Si thin strips were prepared by symmetric and asymmetric cold rolling from commercial grain oriented silicon steel sheets, then annealed with and without a magnetic field. Magnetic field of 12T was applied along the rolling direction. Magnetic annealing does not essentially change the texture development that recrystallization texture consists mainly of η fiber (RD//<001>), and the strongest component tends to transform from Goss ({110}<001>) to {210}<001> with the increase in speed ratio and annealing temperature. But magnetic annealing promotes Goss component in the strips rolled with small speed ratios, while decreases {210 <001> component in those rolled with large speed ratios. Possible effect mechanism of magnetic annealing was discussed.

Cold Rolling Texture

Fe-3.10%Si thin strips were prepared from commercial grain oriented silicon steel sheet by cold rolling with different speed ratios and annealed at 1123K in vacuum, the cold rolling and recrystallization textures were analyzed. Cold rolling texture consists mainly of {111}<112>, {554}<225> and {332}<113> components, while their orientation densities vary with speed ratio and layer through strip thickness. Recrystallization texture development depends on speed ratio obviously, and the peak orientation density deviates from {110}<001> towards {210}<001> with the increase in speed ratio.

The effects of a 2 T pulsed magnetic field primary annealing process on microstructure evolution and grain boundary characteristics in two-stage cold-rolled silicon steel were examined. Pulsed magnetic annealing increased grain size through the application of relatively smaller intensity of magnetic fields (2 T), compared to steady magnetic annealing. The effect of increasing grain size may be attributed to the magnetic acceleration effect of boundary motion under magnetic pulse conditions. Pulsed magnetic annealing may serve to enhance the relative intensity of the {111} component and decrease the frequency of low-angle misorientations. Repeated magnetostriction induced by pulsed magnetic field applications may accelerate overall dislocation motion. These findings suggest that pulsed magnetic fields require relatively lower intensities than steady magnetic fields to achieve superior results, providing a potentially viable alternative for industrial annealing processes for electrical steels.

Linear Synchronous Motors

Thrust performance is one of the important indexes of permanent magnet linear synchronous motors. The traditional non-oriented silicon steel sheet is used as the core material of the permanent magnet linear synchronous motor, which limits the performance of the permanent magnet linear synchronous motors. For the oriented silicon steel sheet has a higher magnetic permeability in the rolling direction, a permanent magnet linear synchronous motor with similar number of poles and slots made of oriented silicon steel is proposed in this paper. By measuring the B-H curves of the rolling direction and the cutting direction, the thrust properties of the two motors made of traditional silicon steel sheets and oriented silicon steel sheets are analyzed and compared by the finite element method (FEM) under rated load and overload conditions respectively. The thrusts under different tooth-yoke ratios are discussed in the end.

Cold Rolled

The annealing of cold rolled (82%) titanium sheet at 750°C in a magnetic field of 19.4 Tesla results in a distinct difference between texture peaks when the sample is tilted by +30° or -30° to the field direction around the rolling direction, i.e. c (<0001>)-axis of grains corresponding to one texture component is aligned normal to the field direction. This result is attributed to grain growth affected by an additional driving force arising in a magnetic field by the anisotropy of the magnetic susceptibility of titanium.

The Magnetic Field

Purpose – The magnetostriction of grain-oriented electrical silicon steel sheet is studied for the magnetic field direction along the rolling direction and deviating from it. The method of calculating the vibration of transformer is developed through COMSOL. The paper aims to discuss these issues. Design/methodology/approach – Measurements of signals of magnetostriction and magnetic polarization, and calculation through software. Findings – The angle between the magnetic field direction and the rolling direction does a great influence on magnetostriction strain. Originality/value – The maximum λ p-p of transversal magnetostriction is above 30 times more than the value when the angle is 0°. The transversal magnetostriction is a main reason of vibration increasing at the corner of transformer.

The effects of magnetic annealing on recrystallization and texture evolution in asannealed interstitial-free (IF) steel sheet were investigated by means of X-ray diffraction ODF analysis, SEM-EBSD analysis, and optical microstructure observation. During the magnetic annealing, specimens were placed at the center of the applied magnetic field, with their rolling planes parallel to the field direction (MD) and their rolling direction (RD) normal to the field direction (MD). It was found that the magnetic annealing retards the recrystallization process, but promotes the nucleation at the initial stage of recrystallization. Magnetic annealing did not change the mechanism of recrystallization texture evolution but improved the development of γ-fiber texture during the process of recrystallization, and the magnetically annealed specimen had stronger γ-fiber texture compared with the conventionally annealed specimen; this interesting finding is quite different from the previous work on magnetically annealed IF steel.

Magnetic annealing at five different magnitudes of field was conducted to evaluate the effect of the field on the recrystallized microstructure of Fe-0.75%Si samples. At higher fields the retardation during recrystallization is compensated by the magnetic filed driving force that causes an increase in the grain boundary mobility of grains that have a certain relationship with the direction of the field
