【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、高温溶融物試料採集装置に係わり。[Detailed description of the invention] [Industrial application field] The present invention relates to a high temperature melt sample collection device.

の高温溶融物から試料を採集する装置に関する。For more details, see Solu S11. This invention relates to a device for collecting samples from high-temperature melts such as hot metal or molten ceramics.
溶鋼や溶銑等の高温溶融物から分析用の試料を採集する
手段については、従来から種々の工夫がなされている０

型に吸引管を連設し内部を減圧とすることによりいわゆ
る自吸的に溶融金属を採集する手段が考えられている。Various methods have been used to collect samples for analysis from high-temperature melts such as molten steel and hot metal.
For example, as a method of collecting a molten metal sample into a mold, a method has been considered in which a suction pipe is connected to the mold and the inside is reduced in pressure to collect the molten metal in a so-called self-suction manner.
しかし、自吸式器具もその構造に難点があるため、吸引

ある試料しか得られず、自吸式で″す″のない良好な試
料を得ることができる採集装置は開発されていない。However, self-priming devices also have drawbacks in their structure, such that the molten metal sucked into the mold does not enter the mold properly, or the molten metal that enters the mold dances violently, resulting in only samples with a large amount of However, no self-priming collection device has been developed that is capable of obtaining a good sample without any "waste".

課題を満足する試料採集装置は提案されていない。The problems to be solved by the present invention are, firstly, to obtain a safe analysis sample by stably sucking molten metal etc. into the mold and without any evaporation, and secondly, to obtain a safe analysis sample without passing through.
It is to simultaneously obtain samples for analyzing manganese, phosphorus, sulfur, etc. (sample for XmQV) and samples for analyzing oxygen, nitrogen, hydrogen, etc. Until now, no sample collection device has been proposed that satisfies these issues.

を特徴とする。A high temperature melt sample collection device comprising a mold container into which a high temperature melt such as metal is cast, a high temperature melt suction tube connected to the mold container, and a vacuum capable box housing the entire mold container, The suction tube is raised from the top of the mold container, bent into an inverted U shape, and extended downward to protrude an appropriate length to the outside of the box. It has a structure with an air port, and when the tip of the suction tube (facing downward) is sealed to create a vacuum inside the books, a vacuum is created inside the mold container and the suction tube connected to it. It is characterized by
以下図面に基づいて詳細に説明する。A detailed explanation will be given below based on the drawings.
図面において、１は内部を真空に維持することができる
ボックスであり、２は鋳型容器でありセラミックスある
いは金属で構成する。この鋳型容器には底部に冷し金３
が付設されており、側部上部に空気口４が形成されてい
る。すなわち、ボックス１内が真空にされたときに空気
口４から排気されるため鋳型容器内も真空となる。冷し
金３が存在することにより吸引により鋳込まれた金属等
の溶湯は速やかに冷却固化される。In the drawings, 1 is a box that can maintain a vacuum inside, and 2 is a mold container made of ceramic or metal. This mold container has a cooling metal 3 at the bottom.
An air vent 4 is formed at the upper side. That is, when the inside of the box 1 is evacuated, the air is exhausted from the air port 4, so that the inside of the mold container is also evacuated. Due to the presence of the cooling metal 3, the molten metal, etc., cast by suction is quickly cooled and solidified.
鋳型容器２に連設される吸引チューブ５は、通常石英ガ
ラス等で作られる。この吸引チューブ５は鋳型容器２の
上部に連設し、これを逆Ｕ字形に曲げ下方に延長させた
構成とすることが重要である。そして鋳型容器に形成さ
れている空気口４の位置も該容器の上部付近にあること
が重要である。The suction tube 5 connected to the mold container 2 is usually made of quartz glass or the like. It is important that this suction tube 5 is connected to the upper part of the mold container 2, and that it is bent into an inverted U shape and extended downward. It is also important that the air opening 4 formed in the mold container be located near the top of the container.
これが下方にあると溶融金属の吸引による鋳込みは達成
されない。要するにこの空気口４の位置が上部にあり、
そして吸引チューブ５の連設位置ならびにその構成を図
面に示すとおりとすることにより、溶融金属はボックス
容積の真空能力によって容易に吸引され鋳型容器いっば
いに吸引充填される。If this is below, casting by suction of molten metal will not be achieved. In short, the position of this air port 4 is at the top,
By arranging the consecutive positions of the suction tubes 5 and their construction as shown in the drawings, the molten metal is easily suctioned by the vacuum capacity of the box volume and suctioned and filled into the mold container all at once.
本発明の試料採集装置は吸引チューブ５の先端６をシー

かに溶け、吸引された金属溶湯は鋳型容器内に安定して
鋳込まれる。そして逆Ｕ字形のチューブ部分にも金属溶
湯が密に充填された状態で固化する。The sample collection device of the present invention seals the tip 6 of the suction tube 5, maintains the inside of the box 1 in a vacuum, and uses this state for sampling. That is, the sealing material for the tip 6 is a glass material with a low melting point that melts quickly when it comes into contact with a high-temperature object such as molten metal, and when the tip is immersed in the molten metal, the seal is removed. The material melts quickly, and the sucked molten metal is stably cast into the mold container. Then, the inverted U-shaped tube part is also solidified with the molten metal densely filled.
鋳型容器２が収設されるボックス１の内部空間部分の大
きさは、真空としたときの前記吸引能力によって鋳型容
器２内に溶融金属が充分に入るものでなければならず、
図面に示したかね合いの大きさとすることが望ましい。The size of the internal space of the box 1 in which the mold container 2 is housed must be such that the molten metal can sufficiently enter the mold container 2 by the suction ability when it is evacuated.
It is desirable to have the size of the balance shown in the drawing.
■、鋳型容器２の底部には冷し金が設置されているので
、吸引により鋳込まれた溶融金属等の高温溶融物は速や
かに固化する。(2) Since a chiller is installed at the bottom of the mold container 2, high-temperature melts such as molten metals cast by suction are quickly solidified.
２、鋳型容器２の空気口（排気口）４は図面に示したよ
うに上部付近にあるので、溶融金属等は容器いっばいに
充填される。この結果″す″のないきわめて理想的な試
料が得られる。2. Since the air port (exhaust port) 4 of the mold container 2 is located near the top as shown in the drawing, the container is filled with molten metal, etc. all at once. As a result, an extremely ideal sample with no "holes" can be obtained.
３、鋳型容器から立ち上り逆Ｕ字形となっている部分に
も溶融金属が密に充填せれた状態で固化する。3. The inverted U-shaped part rising from the mold container is also solidified with molten metal densely filled.
４、前記２．で述べた試料はＸ線ＱＶ用試料として使用

素等を分析するための試料として使用される。このよう
に面分析試料が１回のサンプリングで得られることは品
質管理上きわめて重要なことであり、特筆すべき効果で
ある。4. 2. The sample described in 3. is used as an X-ray QV sample. The sample of the tube section mentioned above is used as a sample for analyzing oxygen, nitrogen, hydrogen, etc. Obtaining a surface analysis sample in one sampling is extremely important for quality control, and is a noteworthy effect.
