    摘要: Wear of tuyeres for refining a molten iron is prevented by blowing a CO-containing gas having the defined flow amount, oxygen gas flow amount and CO gas concentration as a shrouding gas which surrounds a core refining gas flow containing oxygen gas through tuyeres of concentric pipes. As the shrouding gas for cooling and protecting the tuyeres, use may be made of an exhaust gas discharged and recovered from a converter or a blast furnace by controlling the concentrations of CO and N.sub.2 in the exhaust gas to the specific limitations.

    摘要: An apparatus and method for continuous casting steel. A vertical continuous-casting mold consists of a pair of long side frames and a pair of short side frames formed of a metal having low electrical conductivity. An immersion nozzle supplies molten steel to the mold. An induction heating coil surrounded by a backup frame surrounds the vertical continuous-casting mold. The induction heating coil induction-heats the surface of the molten steel and neighboring portions thereof.

    摘要: A method of stirring molten metal by repeatedly sucking and rapidly discharging part of the molten metal into and out of a refractory cylinder having a lower opening end immersed in the molten metal in a ladle, comprises operating the stirring under a condition that an inner diameter (d) of the refractory cylinder is less than 1,000 mm, a relation between the inner diameter (d, mm) of the refractory cylinder and weight (W, ton) of the molten metal in the ladle is d/W.sup.0.5 >30, and an immersed depth of the refractory cylinder is within 200-700 mm. A pressurized gas for discharging the sucked molten metal out of the cylinder is introduced thereinto in an inclined direction relative to a vertical line against a point on an opposite inner wall of the cylinder at least 500 mm above the maximum suction level of the molten metal in the cylinder.A refractory cylinder operated in the above manner according to the invention comprises a flange connection between an uppermost and an intermediate cylinder parts of the cylinder at a location higher than the maximum suction height of the molten metal and a further flange connection between the intermediate cylinder part and a lowermost cylinder part. The refractory cylinder comprises at its immersed end a flow restricting opening to obtain more strong stirring the molten metal.

    摘要: According to one embodiment, an electronic apparatus includes a sound characteristic output module configured to analyze audio data in video content data, thereby outputting sound characteristic information indicative of sound characteristics of the audio data. A talk section detection process module detects talk sections in which talks are made by persons, which are included in the video content data, on the basis of the sound characteristic information, and classifies the detected talk sections into a plurality of groups which are associated with different speakers. A display process module displays, on a time bar which is representative of a sequence of the video content data, a plurality of bar areas indicative of positions of the detected talk sections in the sequence of the video content data, in different display modes in association with the groups.
