MAGNETIC ANISOTROPY MEASUREMENT DEVICE

PROBLEM TO BE SOLVED: To measure, especially, the anisotropy in the surface direction of a steel plate, in a magnetic anisotropy measurement device.SOLUTION: First, second, and third magnetization coil members 3A, 3B, and 3C are disposed at positions keeping an angle constant distance of 120[°] about a central virtual point 4 of a steel plate 2 as a measurement object and at the constant distance from the central virtual point 4 so as to face one surface 2A of the steel plate 2. The steel plate 2 is magnetized by a revolving magnetic field Φ, and the magnetization intensity is detected by magnetization intensity detection members 15A1, 15A2, 15B1, and 15B2, and the anisotropy in the surface direction of the steel plate 2 is determined on the basis of the distribution pattern of the magnetization strength in the surface direction.SELECTED DRAWING: Figure 1 【課題】磁気異方性計測装置に関し、特に鋼板の面方向の異方性を計測しようとするものである。【解決手段】計測対象である鋼板２の一面２Ａに対向するように、鋼板２の中心仮想点４を中心として１２０［°］の角等間隔を保つ位置に、第１、第２及び第３の磁化コイル部材３Ａ、３Ｂ及び３Ｃが、中心仮想点４から互いに等しい距離に、配設される。鋼板２を回転磁界Φによって磁化させると共に、当該磁化強度を磁化強度検出部材１５Ａ１、１５Ａ２、１５Ｂ１、１５Ｂ２によって検出して磁化強度の面方向の分布の仕方に基づいて鋼板２の面方向の異方性を判断する。【選択図】図１
