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： One or more streams of molten metal poured into a continuous casting mold are acted on magnetically by static magnetic fields, covering substantially the entire width of the casting mold, thereby reducing the speed of the molten metal streams from the immersion nozzle, unifying the flow profile of the molten metal in the mold, preventing trapping and accumulating of mold powders and inclusions into the cast products. Magnetic poles are provided which are at least as wide as or wider than the minimum width of the cast products and the iron core is arranged on the same face of the casting mold with mutually opposite polarities in the drawing direction. Even if casting conditions change from time to time, defects in final products made of the cast metal are substantially reduced.

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.
