摘要： PURPOSE:To prevent a magnetic field from leaking out and heighten the density of the magnetic field and use a magnetic force line effectively by arranging the external drum of perfect diamagnetic substance, and an internal drum with a fitted coil doubly, and by generating the magnetic field moving between the external drum and the internal drum in tne axial direction, with current flowing to said coil. CONSTITUTION:An external drum 1 and an internal drum 2 are formed with perfect diamagnetic substance in the shape of circular cylinders, namely, superconducting bodies. The external drum 1 and the internal drum 2 are arranged mutually concentrically and doubly. When a coil 3 fitted on the internal drum 2 is excited by three-phase alternating current, and a magnetic field B generated between the external drum 1 and the internal drum 2 is moved, then an electromagnetic force F is generated on the conductor of seawater or the like present between the external drum 1 and the internal drum 2, and a propelling force is obtained. In such an electromagnetic force generator, the magnetic force line B generated by the coil 3 is confined and can be effectively used, and energy loss can be reduced. Besides, the electromagnetic force works as internal pressure on the external drum, and so the bearing mechanism can be simplified.

摘要： PURPOSE:To obtain the distributed state of stable energy by arranging the drum bodies of conductors doubly to compose the respective drum bodies so that a closing loop may be formed with current flowing in the axial direction, and by arranging electrode plates for permitting the current to flow to a section between the drum bodies in the radial direction. CONSTITUTION:An external drum 11 and an internal drum 12 are formed witn superconducting bodies in the shape of circular cylinders, and are arranged doubly and mutually concentrically. Current I0 flowing to the external drum 11 and the internal drum 12 in the axial direction flows in the directions opposite to each other, and the drums are composed so that a closing loop may be formed with the current. Besides, electrode plates 13, 14 are arranged to permit current to flow between the external drum 11 and the internal drum 12 in the radial direction. By a magnetic field B to be generated in the circumferential direction by the current I0 flowing to the external drum 11 and the internal drum 12, and current I flowing in the radial direction due to tne electrode plates 13, 14, a Lorentz force F is generated, and then, thrust is obtained. Accordingly, this electromagnetic force generator can be used for the main engines of electromagnetic propulsion vessels, electromagnetic pumps, rail guns, and the like.

摘要： PURPOSE:To execute good continuous casting operation without any leakage by arranging slantable coils wound at gap near boundary of a tundish nozzle and mold with large inner diameter, and adjusting slant of the coils in accordance with detecting of contact position of molten metal, shrunk by electromagnetic force, with the mold. CONSTITUTION:The slantable (theta) coils 98, 99 wound are arranged at the gap near the boundary 17 of the nozzle qr of the tundish 1 and the mold 3 with large inner diameter. The molten metal 95, of which diameter is reduced by the electromagnetic force generated by AC current of the coils 98, 99, is brought into contact with the mold 3 through flowing lubricant 46 at the contacting start position 112, to execute horizontal continuous casting toward casting direction 45 without any sticking of solidified shell to the mold 3. The contacting position 112 with the molten metal is detected by the position detecting means 109 through thermocouples 108, and the coils 98, 99 are slanted at suitable angle theta, to compensate a gap of the contacting position 112 by gravity. Further, thickness of the shell is also adjusted by slanting the coil. Therefore, the leakage of the molten metal 95 is prevented and the solidified shell is developed uniformly without any sticking to the mold 3 and good horizontal continuous casting operation is executed.

摘要： PURPOSE:To make the contact pressure of molten metal with the inside surface of a mold uniform and to prevent the deformation, crack, etc. of a steel ingot by acting electromagnetic forces having the distribution corresponding to a static pressure distribution upon the molten metal in the mold. CONSTITUTION:Plural pieces of solidification thickness gages which measure the thickness of the solidified shell formed on the surface layer part of molten metal 12 are provided circumferentially at the outlet end of a mold 3 to measure the distribution of the contact pressure of the molten metal 12 along the circumferential direction. A cylinder 55 is extended or contracted by a control means so that the solidification thicknesses measured with the respective solidification thickness gages are made equal. Since an electromagnetic field generating means 34 is displaced vertically in a containing space 40 by said movement, the distribution of the electromagnetic forces acting upon the surface layer of the metal 12 can be changed. Therefore the contact pressure of the molten metal 12 with the inside surface of the mold tube 15 is made always uniform along the circumferential direction.

摘要： PURPOSE:To obtain a good ingot by controlling the electromagnetic force of a coil according to the change in the level of the molten metal in a tundish thereby maintaining the contact position of the molten metal with the inside surface of a mold constant and making the length of a cooling zone constant. CONSTITUTION:The level l of the molten metal 12 in a tundish 1 detected with a television camera 22 is applied to a controller 24. The controller 24 regulates supply electric power by controlling an electric power source 25 for supplying electric power to an electromagnetic field generating means 18 according to the fluctuations of the level l. A position detecting means 26 which detects a contact starting position 47 is provided in the part near the tundish nozzle 14 of a mold 3 and the quantity of the supply electric power is regulated in such a way that the position 47 comes to the predetermined constant position. Thus the position 47 and a detecting start position 44 are maintained constant irrespectively of the level l, the length of the cooling zone for the metal 12 is made constant and the good ingot is obtained.

摘要： PURPOSE:To make it possible to obtain cast bodies of a large-sized section by disposing electromagntic field generating means near the end face facing a tundish nozzle of a mold, and applying electromagnetic forces to molten metal. CONSTITUTION:When AC current flows in the strands of an electromagnetic field generating means 18, the eddy currents corresponding to the rate of change in electric currents are generated in opposite directions in molten metal 12. Electromagnetic forces directing toward the inner side in a radial direction act upon the molten metal 12 over the entire circumference, and the molten metal 12 passing through a tundish nozzle 15 is throttled. If in another electromagnetic field generating means 20 the electric current increases in the strands of the electromagnetic field generating elements, eddy currents are generated in the direction of an arrow 33 in the metal 12 in a mold 3. The magnetic fields are generated toward the other side on the plane of the paper shown by a reference code 34. The electromagnetic force shown by an arrow 35 is generated in the metal 12 in the mold 3. Then, the metal 12 throttled by the means 18 spreads outward in the forward of a drawing direction 45 by the means 20 and the molding is performed by the mold 3.
