Effect of Annealing Microstructure and Texture on Magnetic Properties for the Low Grade Cold Rolled Non-oriented Silicon Steel by CSP Process

The distribution and composition of the texture and microstructure in two different the low grade cold roiled non-oriented silicon steel have been investigated using optical microscope and X-ray diffraction ODF analysis methods.The influences of texture types and microstructure on the magnetic properties are discussed. The result shows:as the content of（Si+Al）increase,grain size is bigger and iron loss is reduced;with in- creasing of orientation in density of the {100}＜0vw＞and a orηfiber texture,magnetic properties is in- creased,and the intensity of {111}＜112＞component decreasing causes magnetic flux increasing obviously.
