The present invention provides a steel sheet transport device which can ensure a sufficient magnetic flux penetration depth during transport of a steel sheet, and can simply and accurately control the magnetic flux penetration depth according to the number of lifted steel sheets, thereby achieving both controllability during control of the number of lifted steel sheets and suspension stability during transport at a high level. And the lifting magnet can be arranged to be a compact and light device structure. The present invention is provided with a plurality of electromagnet coils (1) which are disposed in a concentric shape and are capable of independently performing on-off control and voltage control, and which can sufficiently ensure the magnetic flux penetration depth during the conveyance of a steel plate by selectively using the plurality of electromagnet coils or using the plurality of electromagnet coils in an appropriate combination. And the magnetic flux penetration depth can be controlled simply and with high precision according to the number of steel plates lifted.
提供能够充分确保钢板运送时的磁通穿透深度且根据钢板的吊起张数而简单且高精度地控制磁通穿透深度、由此能够以高的水平兼顾悬吊张数控制时的控制性和运送时的悬吊稳定性、而且能够设为紧凑且重量也小的装置结构的起重磁铁。具备配置成同心状且能够分别独立地实现接通‑关断控制及电压控制的多个电磁铁线圈(1),通过将该多个电磁铁线圈选择性地使用或适当组合而使用,能够充分确保钢板运送时的磁通穿透深度,并且能够根据钢板的吊上张数而简单且高精度地控制磁通穿透深度。
