摘要： A ladle (1) equipped with a gas blowing device having an accumulator cylinder (7) is provided, which has the capability of suppressing molten metal from penetrating into an injection plug (3) embedded in the ladle (1) and having a high resistance leading to a longer service life of the injection plug (3). The gas-blowing device (5) comprises a main pipe (8) for blowing gas into the ladle (1) via a gas-blowing plug (3) from a positionally independent gas supply source (4); an accumulator cylinder (7) for accumulating the gas supplied through the main pipe (8); and a controller (6). The controller (6) is used for accumulating the gas into the accumulator cylinder (7) when the gas blowing through the main pipe (8) begins or when the gas blowing is carried out, and for starting to blow the gas accumulated in the accumulator cylinder (7) simultaneously with a termination of the gas blowing through the main pipe (8).

摘要： On the inner surface of sensor element (1) made of proton conductive solid electrolyte with perovskite structure and enclosed at its lower end, a reference electrode (2) constituted of porous electrode is formed, and a measuring electrode (3) constituted of porous electrode is formed on the outer surface thereof. And, the reference electrode and the measuring electrode are gas-tightly separated by sealing material. The sensor prove is inserted into ceramic sensor holding cup (10) and both are fixed in such a way that a part of the measuring electrode (3) extrude into said holding cup. Then, by dipping the holder into molten metal (19)by facing its opening part downwards, a space contacting with molten metal is enclosed in the holding cup.
Thereby, reduction of solid electrolyte constituting the sensor element can be prevented, and hydrogen concentration in molten metal can be accurately measured without direct dipping the sensor element into molten metal. Thereby, it is possible to provide a sensor probe and a method for measuring hydrogen concentration in which hydrogen concentration can be continuously measured for long period and an apparatus with smaller size can be made.
摘要翻译：在由具有钙钛矿结构的质子传导性固体电解质制成的传感器元件（1）的内表面上，封装在其下端，形成由多孔电极构成的参比电极（2），由多孔电极构成的测量电极形成在其外表面上。并且，参考电极和测量电极由密封材料气密分离。将传感器证明插入到陶瓷传感器保持杯（10）中，并且两者都固定成使得测量电极（3）的一部分挤出到所述保持杯中。然后，通过向下面朝向其开口部分将保持器浸入熔融金属（19）中，与熔融金属接触的空间被封闭在保持杯中。由此，可以防止构成传感器元件的固体电解质的降低，并且可以精确地测量熔融金属中的氢浓度，而无需将传感器元件直接浸入熔融金属中。因此，可以提供一种传感器探头和用于测量长时间连续测量氢浓度的氢浓度的方法，并且可以制造具有较小尺寸的装置。

摘要： A melt (2) is stored in a vessel (5) placed in a decompression vessel (10). On the bottom of the vessel is arranged a bubble generator (9) made of porous bricks, and bubbles of argon gas are introduced into the melt through this bubble generator. Also a lower half section of a degassing member is immersed in the melt. This degassing member (6) has a cylindrical form with the lower end closed and the section immersed in the melt is made of a porous material permeable to gases and impermeable to melts.
With these features, a surface of molten metal can be put under reduced pressure and high content components of the melt can be removed by means of bubbling, and also solute components in the melt can be removed into bubbles of argon gas. Also, gases in the melt and gases produced by reactions between the melt and the porous material can be sucked through a wall of the degassing member into inside thereof and removed.
摘要翻译：将熔体（2）储存在放置在减压容器（10）中的容器（5）中。在容器的底部布置有由多孔砖制成的气泡发生器（9），并且通过该气泡发生器将氩气气体引入熔体中。此外，脱气构件的下半部分浸入熔体中。该脱气构件（6）具有圆柱形形式，其下端封闭，并且浸入熔体中的部分由可渗透气体并且不能熔化的多孔材料制成。通过这些特征，能够减少熔融金属的表面，通过鼓泡可以除去熔融物的高含量成分，并且可以将熔融物中的溶质中的溶质除去到氩气气泡中。此外，通过熔体和多孔材料之间的反应产生的熔体中的气体和气体可以通过脱气构件的壁被吸入其内部并被去除。

摘要： A melt (2) is stored in a vessel(5). A lower half of a degassing member (6) is immersed in the melt. The degassing member has a cylindrical form with the lower end closed, and the lower half section is made of a porous material which is permeable to gas and impermeable to melts as molten metal, molten slag, or molten matte. This lower half section is a partitioning member (6a). When an internal space inside the degassing member is sucked to realize vacuum or reduced pressure atmosphere, gas-producing components in the melt pass through the partition member (6a) of the degassing member, and are exhausted to inside the degassing member, thus being separated from the melt. Also, by making the degassing member rotate or move in a horizontal or vertical direction, the melt is stirred. With these features, gas-producing components in the melt can be removed at a high efficiency.
