摘要： A flaw detection device for a steel bar enabling inspection of a high temperature steel bar at a high temperature.A pre-treatment unit 31, detection unit 32, and post-treatment unit 33 are arranged along a running direction of a steel bar 10. The pre-treatment unit and post-treatment unit have the same structure. Direct current coils 312 and 332 are wound around the outside of the sleeves 311 and 331. The steel bar is magnetically saturated by the direct current magnetic field. An eddy current is generated at the surface of the steel bar by an alternating current coil 321 of a detection unit 12. The change in the magnetic field caused by the eddy current is detected by the detection windings 322 and 323. The sleeves are made of nonmagnetic materials, so the strength of the direct current magnetic field becomes flat along the running axis of the steel bar. Even when moving the steel bar at a high speed, the occurrence of noise due to changes in strength of the direct current magnetic field is suppressed.

摘要： A method and an apparatus for continuously casting a metal slab made of steel are provided for uniformly circulating molten metal on a meniscus in a mold. The cast metal slab has no surface defect such as a slitting. On the meniscus, the method and apparatus operates to generate electromagnetic stirring thrusts along two long mold sides, these thrusts being opposed to each other. The thrust oriented from a dipping nozzle to the short mold side is made larger than the thrust oriented from the short mold side to the dipping nozzle. A circuit for connecting each coil of a shifting field electromagnetic stirring coil part with a three-phase power supply is symmetric to another circuit with respect to the dipping nozzle. The circuit is divided into two parts along each long mold side. The divided circuit parts are located in parallel but have respective impedances.
