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： A method of removing non-metallic inclusions from a molten metal by allowing the molten metal to pass through at least first and second vessels which are intermediate between a ladle and a mold. The molten metal is made to stay in the vessel for a period not shorter than 40 seconds while a horizontal rotation is imparted to the molten metal in the first vessel. The molten metal is then transferred from the first vessel to the second vessel. The molten metal in the second vessel is then heated. This method is suitably carried out by an apparatus comprising a first vessel having a discharge opening at its bottom and surrounded by a rotational magnetic field generating device for centrifugation of the molten metal in the first vessel, and a second vessel for receiving the molten metal discharged from the first vessel and provided with a heating device for heating the molten metal received therein.

摘要： A process for producing an extremely low carbon steel in a top- and bottom-blown converter. The process is characterized in top-blowing a mixed gas of oxygen gas and an inert gas onto a molten steel in the top- and bottom-blown converter. The mixed gas is blown through a top-blowing lance at the final decarburization stage, while a gas (selected from a group consisting of an inert gas, oxygen gas and a mixture of oxygen and an inert gas) is bottom-blown into the molten steel in the converter.

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.
