摘要： This invention relates to a process for refining metals in a refining vessel, by means of a tuyere embedded in the bottom or sidewall of the vessel and through which a refining gas is blown into the vessel. The tuyere is composed of at least three concentric pipes, the refining gas being made to pass through the central pipe and a protective medium being made to pass into the vessel through the spaces between the pipes which surround the central pipe. All of the pipes except the outermost pipe which is fixedly embedded in the refractory lining of the vessel, are individually movable longitudinally into the vessel.
摘要翻译：本发明涉及一种通过嵌入在容器的底部或侧壁中的风口，在精炼容器中精炼金属的方法，并将精炼气体吹入容器中。风口由至少三个同心的管道组成，精炼气体被制成通过中心管道，保护介质被制成通过围绕中心管道的管道之间的空间进入容器。除了固定地埋在容器的耐火衬里中的最外面的管子以外的所有管子可以纵向地单独移动到容器中。

摘要： An improvement in the refining of molten metals in a converter by means of oxygen introduced into the metal through tuyeres which include two concentric pipes, oxygen being passed into the melt through the central pipe and a protective fluid being passed into the melt as a sheath or screen around the oxygen, through the clearance space between the two pipes. In the present invention two tuyeres, disposed horizontally and each passing through the convertor sidewall permit refining to be accomplished without any slopping or splashing of the melt and with only minor wear of the convertor lining.

摘要： A method of casting steel at a lower overheated temperature during continuous casting, wherein the inner surface of a tundish is heated to a temperature which approximately corresponds to the temperature of the steel in a ladle, the tundish is filled with steel, and the steel is poured into at least one mold. According to the invention a discharge spout of the tundish which opens above the reference level of the metal bath, prior to casting and during heating of the tundish is brought into a position which occupies the lowest point of the inner surface of the tundish, the heating of the tundish is continued until adjusting an approximately stationary thermal gradient between the inner and the outer surfaces of the tundish, and prior to pouring of the steel into the mold the tundish is brought into its casting position.The tundish for the pouring of steel during continuous casting comprises a substantially troughlike lower portion and a domed cover member, at least one bottom nozzle provided for the tundish lower portion, said cover member being provided with an opening for the pouring in of the steel melt from a ladle, and a heating device is arranged above the reference bath level of the tundish. The tundish has a lining possessing a heat conductivity resistance of at least 0.25 m.sup.2.h. .degree.C/Kcal, and is further provided with a discharge spout partially possessing a substantially tubular-shaped cross-section and opening above the reference level of the metal bath. There is also provided means for displacing the tundish about a horizontal axis.
