    摘要： A method for the continuous production of cast steel strands which are 200 mm.times.200 mm or less in cross-section by a continuous casting process in which molten steel containing 0.20% or less of carbon is fed into a casting mold with a lubricant through a submerged nozzle or in an open stream and continuously drawn out downwardly of the casting mold. The method includes the steps of (a) electromagnetically stirring the molten steel at a position within said casting mold by the application of a magnetic field induced by introducing into an electromagnetic coil an alternating current of a frequency (f) in the range of 1.5 to 15 hertz and maintaining the magnetic flux density (Gaub) in the range of 602e.sup.-0.10f to 2441e.sup.-0.11f at the center of the electromagnetic coil, and (b) electromagnetically stirring the molten steel at a position in the final solidifying zone, of said continuously cast strand, in which the shorter diameter of the molten steel pool is smaller than 1/2 the length of the shorter side of the cast strand, by the application of a magnetic field induced by introducing an alternating current into an electromagnetic coil and maintaining the magnetic flux density (Gaub) in the range of 0.2.multidot.D.sup.2 +280 to 0.343.multidot.D.sup.2 +451 at the center of the electromagnetic coil, wherein D is the solidified shell thickness in millimeters of said continuously cast strand, the value of D ranging from 20 to 90. The method thereby permits the production of low carbon killed steel billets which are improved as to negative segregations, center cavities, inclusions, surface quality, cold forgeability, and machinability, by a continuous casting process at low cost.

    摘要： A device for electromagnetically regulating the pouring rate in continuous casting, including a cylindrical molten steel container having a molten steel inlet formed in a peripheral section of an upper surface thereof and a molten steel outlet formed in central section of a lower surface thereof to pour the molten steel into a mold, and electromagnetic coils disposed around the side wall of the molten steel container so as to generate a rotating magnetic field perpendicularly to the side wall. The pouring rate is determined by the interactive function of the head of the molten steel in the tundish disposed above the molten steel container with the outlet thereof joined to the inlet of the molten steel container, the intensity of the rotating magnetic field, namely, the magnitude of the electric current supplied to the electromagnetic coils, and the size of the molten steel outlet, namely, a replaceable pouring nozzle.
