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.

摘要： In order to securely hold a moving belt of a continuous casting device against selective movable side walls, a first group of rotatable control rods which are disposed in a first supply header and an adjacent exhaust header are arranged to produce narrow high pressure zones in the film defined between the cooling pad in which the header are formed and the moving belt. These zones can be selectively moved to juxtapose the side walls when the gap between the walls is adjusted. A second group of rotatable control rods which are disposed in second and third supply headers selectively heat the side edges of the belt which are relatively cool as compared with the center section which is exposed to molten metal. As the side walls are moved apart the width of the edge sections which are exposed to pre-heated coolant can be reduced and the amount of normal temperature coolant applied thereto also increased.

摘要： A process for continuously casting steel slabs employing a molten steel containing an oxygen concentration of 30 ppm or less, preferably, 20 ppm or less, using a straight immersion nozzle to which an inert gas is not injected, and disposing a static magnetic field generator on the back surface of the mold for applying the strong static magnetic field to the molten steel within the mold, thereby restricting the flow of the molten steel. With this process, it is possible to prevent the nozzle blocking, and hence to obtain the steel slabs excellent in the internal and surface qualities.

摘要： A method and apparatus for continuous casting of an elongated thin metal strip achieves substantially high yield without allowing break-out or sticking. The method for casting a continuous elongated metal strip includes a step of driving endless belts at a varying speed so as to apply jerks to the slightly and half-solidified metal that release the metal from the surfaces of the stationary side walls. Applying jerks to the casting chamber by varying the driving speed of the endless belt ensures that the solidifying metal will travel smoothly and thus ensures a high manufacturing yield.

摘要： A belt type cast sheet continuous caster of the type comprises a pair of opposed circulatorily movable belts, a pair of opposed side plates arranged along opposite side edge portions of the movable belts, coolers which each have numerous water feed openings and water discharge openings opened to the movable belt and are arranged behind the respective movable belts, and movable partition plates which are placed in respective cooling headers and each connected to driving means for moving the partition plates in a width direction of a cast sheet. A casting space is defined by the movable belt and the side plates. Melt leakage at sliding portions between mold short side plates and the metal belts in a belt type cast sheet continuous caster comprising the metal belts and the mold short side plates arranged along side edge portions of the metal belts and cooleres, which each have numerous water fed openings and water discharge openings opened to the metal belt and are arranged behind the respective metal belts, is prevented by controlling gaps between the metal belts and the mold short side plates through varying a pushing force of the metal belts to the mold short side plates.

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.
