Document Type and Number:
Japanese Patent JP6662173
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a non-oriented electromagnetic steel sheet for a straight moving iron sheet excellent in not only flow of magnetic flux in a sheet plane, but also flow of changing magnetic flux at a plate end part.SOLUTION: There is provided a non-oriented electromagnetic steel sheet for a straight moving iron sheet having a chemical composition containing, by mass%, one or two kind selected from Si:0.1-3.5%, Mn:0.1-1.3% and Ni:0.5-3.5%, C:0.003-0.005%, N:0.003% or less, S:0.003% or less and the balance Fe with inevitable impurities and strength I(200), I(310), I(420), I(110) of {200} surface, {310} surface, {420} surface, {110} surface to a random surface respectively in an inverse pole figure obtained by an X ray diffraction measurement in a product center layer within 10% of sheet thickness from a center of a sheet thickness direction to the sheet thickness direction, satisfying all of I(200)≥0.50, I(310)≥0.50, I(420)≥0.40 and I(110)≥0.30.SELECTED DRAWING: Figure 4
