摘要： Coils (220, 320) are respectively arranged on a front side and a rear side of a planned conveyance plane (CP). Non-edge cores (211, 311) and edge cores (212-213, 312-313) are arranged with respect to the coils (220, 320). The non-edge cores (211, 311) are so-called T-shaped cores, and arranged at center regions in an x-axis direction. Two edge cores (212-213, 312-313) are so-called E-shaped cores, and arranged on both sides in the x-axis direction of the non-edge cores (211, 311), respectively. An interval between upstream-side leg portions (2122, 3122) and downstream-side leg portions (2123, 3123) provided to the edge cores (212, 313) and the planned conveyance plane (CP), is shorter than an interval between parts of the non-edge cores (211, 311) except for center leg portions (2111, 3111) thereof and the planned conveyance plane (CP).

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.
