    摘要： During continuous casting of metals, a non-moving, vibrating magnetic field is applied to a molten metal in a casting mold to impose only vibration on the molten metal. This continuous casting method can produce a cast slab much less susceptible to flux entrainment, capture of bubbles and non-metal inclusions near the surface of the molten metal, and surface segregation. The magnetic field is preferably produced by arranging electromagnets in an opposing relation on both sides of the mold to lie side by side in the direction of longitudinal width of the mold, and supplying a single-phase AC current to each coil. The single-phase AC current preferably has frequency of 0.10 to 60 Hz. A static magnetic field can be applied intermittently in the direction of thickness of a cast slab. This technique can produce a cast slab substantially free from the flux entrainment and the surface segregation. Preferably, the static magnetic field is intermittently applied under setting of an on-time t1=0.10 to 30 seconds and an off-time t0=0.10 to 30 seconds. Also, the static magnetic field is preferably applied to the surface of the molten metal.

    摘要： In this invention, the smelting reduction operation can be carried out in a high efficiency by charging a carbonaceous material in such an amount that total surface area is not less than 60 m.sup.2 per 1 ton of slag weight. Carbon substance finely particulating through thermal crumbling under a high-temperature atmosphere inside the vessel is used as the carbonaceous material, whereby it is possible to stably conduct the smelting reduction while controlling the scattering of the carbonaceous material, and also the erosion, particularly locally erosion of refractory in the smelting reduction furnace, which was a serious problem in the conventional technique, can considerably be decreased to largely prolong the service life of refractory.

    摘要： Molten steel is poured using an immersion nozzle and a direct current magnetic field zone is applied to a cast slab over the entire width in the thickness direction thereof at a predetermined distance below the molten metal level in a continuously-casting mold. The immersion nozzle is provided with ejection holes located in at least upper and lower stages, at least one lower ejection hole is disposed such that these satisfy the following formula (1). The supply rate of molten steel from the upper ejection holes is set smaller than the rate consumed by solidification in an upper pool, and a particular solute element is added to the molten steel in the upper pool. 0
