Non Oriented Electromagnetic Steel Plate, Original Plate For Non Oriented Electromagnetic Steel Plate, Core, Cold Rolled Steel Plate, Method For Manufacturing Non Oriented Electromagnetic Steel Plate, Method For Manufacturing Original Plate For Non Oriented Electromagnetic Steel Plate, And Method For Manufacturing Cold Rolled Steel Plate

Abstract: This non-oriented electromagnetic steel plate has a prescribed chemical composition. The chemical composition satisfies 1020-325×[C]+33×[Si]+287×[P]+80×[sol.Al]-120×([Mn]+[Mo]+[Cu])-46×([Cr]+[Ni]): 750 to 1050. When Ahkl-uvw represents the surface area ratio of crystal grains in a \{hkl\} orientation to the entire field of view when a plane parallel to a rolled surface at a depth at 1/2 of the plate thickness from the top surface is measured by SEM-EBSD, A411-011 is greater than or equal to 15.0%. According to an ODF for f2=45°, the non-oriented electromagnetic steel plate has the maximum intensity at f1=0 to 10° for f1=0 to 90° and F=20°, has the maximum intensity at f=5 to 35° for f1=0° and F=0 to 90°, and has an average crystalline particle diameter of 50 to 150 µm.
