IRON CORE, COLD RE-ROLLED STEEL SHEET, COLD RE-ROLLED STEEL SHEET MANUFACTURING METHOD, AND IRON CORE MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an iron core which has excellent magnetic properties and dimensional accuracy, and whose space factor decrease is suppressed.SOLUTION: An iron core composed of a steel sheet in which an area ratio of a crystal grain having a crystal orientation of {100}001(±30°) is 50% or more, and an area ratio of a crystal grain having a crystal orientation of {110}110(±30°) is 20% or more.SELECTED DRAWING: Figure 3
