STEEL MAGNETIZATION APPARATUS

摘要

PURPOSE: A steel magnetization device is provided to accurately measure defects as magnetization can be uniformly generated on a steel sheet in a width direction of a steel sheet. CONSTITUTION: A steel magnetization device (110) includes a first yoke unit (120), a pair of second yoke units (130), and a magnetic flux varying unit. The steel magnetization device is arranged adjacent to a steel sheet (100) and magnetizes the steel sheet. The first yoke unit has magnetism arranged in a width direction of the steel sheet. The second yoke units arranged on the front and rear surface of the first yoke unit are extended to be adjacent to the steel sheet and magnetized by the first yoke unit. The magnetic flux varying unit is connected to the first and second yoke units and functions as a medium for varying the magnetic flux in the width direction.
