摘要： A method of guiding and transferring a rapidly quenched metallic tape includes steps of peeling the rapidly quenched metallic tape produced by solidification through rapid quenching on a circumferential surface of a single cooling roll rotating at a high speed, introducing the metallic tape into a cylindrical transfer guide to a pinch roll unit arranged at a terminal end of the transfer guide to catch the metallic tape by the pinch roll unit, and moving the pinch roll unit to a winder for the metal tape. The metallic tape is fed in the transfer guide substantially without being in contact with the transfer guide. An apparatus for guiding and transferring a rapidly quenched metallic tape includes a cylindrical transfer guide arranged on a normal line of a single cooling roll for introducing and guiding the metallic tape, a pinch roll unit arranged at a terminal end of the transfer guide for catching the metallic tape, and a transfer trolley for transferring the pinch roll unit to a winder for the metallic tape.

摘要： When molten steel jetted through an immersion nozzle into a mold for continuous casting is controlled by applying static field between opposed side walls of the mold for the continuous casting, this invention provides cast slabs having good surface and internal qualities by feeding molten steel to the mold for the continuous casting at a throughput of not less than 6 t/min and simultaneously applying a static field having a magnetic flux density of at least 0.5 T to a meniscus portion in the mold for the continuous casting and a static field having a magnetic flux density of not less than 0.5 T to a lower portion of molten steel jetted out from a discharge port of the immersion nozzle.

摘要： In a continuous casting of steel slab, a molten steel is provided having an oxygen concentration of not more than 35 ppm and is supplied from a tundish into a continuous casting mold through a straight immersion nozzle having an open end at the forward end thereof, the mold consisting of a combination of a pair of narrow face mold walls and a pair of wide face mold walls. A traveling magnetic field generating device is disposed on a central area of the outer surface of the wide face mold walls. While the open forward end of the nozzle is positioned in the magnetic field region of the traveling magnetic field generating device, a traveling magnetic field which is perpendicular to the wide face mold walls and which is traveling upward is applied to a flow of the molten steel discharged from the nozzle, thereby controlling the flow. Preferably, an upper or lower static magnetic field generating device or both of them may be also used.
