摘要： A method of removing non-metallic inclusions from a molten metal comprises the step of simultaneously applying both a horizontal rotation of the molten metal and heating of the molten metal by induction heating. After the simultaneous application of rotational force and heat, the induction heating may be stopped while the horizontal flow of the molten metal is maintained, so as to promote the separation of the particles of the inclusions. The method is carried out by using an apparatus which has a vessel which contains the molten metal, a rotary magnetic field generating device surrounding the vessel, and an induction heating device also surrounding the vessel. Each of the rotary magnetic field generating device and the induction heating device may be divided into a plurality of circumferential segments and arranged such that the segments of both devices are alternately disposed around the vessel.

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： An apparatus for removing non-metallic foreign matter in a molten steel includes a tundish and a coil device. The tundish is an intermediate container receiving the molten steel from a ladle and feeding a purified molten steel by removing the non-metallic foreign matter in the molten steel. For removing the non-metallic foreign matter, the tundish has a swirl flow bath and a floatation bath. In the circumference of the swirl flow bath of the tundish, a coil device is arranged for flowing the molten steel in the swirl flow bath in swirl fashion. The tundish and the coil device are formed separately and constructed for relative movement to each other. The molten steel in the swirl flow bath of the tundish is flown in swirl fashion in the horizontal direction by a magnetic field generated by the coil device. At this time, the molten steel forms a parabolic concaved surface. The non-metallic foreign matter in the molten steel is forcedly floated up on the parabolic surface portion of the molten steel, which is removed by an appropriate means. The molten steel thus purified flows into the floatation bath from the swirl flow bath. With the static flow in the floatation bath, the residual non-metallic foreign matter floats up. The purified molten steel is poured into the mold through the bottom of the floatation bath.

摘要： A method of oscillating a mold of a vertical continuous caster of the type having a pair of longer side frames and a pair of shorter side frames. The mold is oscillated vertically during the casting. A pair of mold walls, e.g., the longer side frames, are moved towards and away from the cast metal in synchronization with a vertical oscillation of the mold, so as to control the condition for supplying a mold powder into the gap between the mold walls and the cast metal.

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.

摘要： A groove (Da) extending in a Y-axis direction of a workpiece (D) is finish machined with an offset tool (T) that has a cross-section with a shape (L3) offset in a reducing direction by only a predetermined offset amount relative to a finished shape (L1) of the groove (Da) and that rotates around an axis of rotation parallel to a Z axis. Each time an incising step in which the offset tool (T) is relatively moved within the X-Z plane only by a predetermined distance on the circumference of an imaginary circle (C) having an initial position as its center and the offset amount (o) as its radius is carried out, a cutting step in which the entire length of the groove (Da) is cut while relatively moving the offset tool (T) in the Y-axis direction is carried out repeatedly. This enables the load imposed on the offset tool (T) to be suppressed compared with the case of a forming tool, which cuts a wide region of the groove (Da) of the workpiece (D) all at once, thus providing a method of machining a workpiece with an offset tool (T), the method allowing the durability of the offset tool (T) to be enhanced and the finishing precision of a machined face to be increased.
