Description
【０００１】[0001]
本考案は、例えば溶鋼を分析のために採取する溶鋼採取容器に関するものであ る。 The present invention relates to a molten steel collection container for collecting molten steel for analysis, for example.
【０００２】[0002]
従来から、溶鋼試料を採取する場合には金属製の容器を用いる場合が通常であ る。 Conventionally, it is usual to use a metal container when collecting molten steel samples.
【０００３】[0003]
しかしながら、分析用材料として金属製の容器で溶鋼を採取すると、溶鋼が急 激に冷却され温度が低下するため、溶鋼中に含まれる酸素、窒素、水素等のガス の溶解度も急激に低下する。この結果、ガスが短期間に放出され、採取中に溶鋼 が飛散したり、試料中に気泡が発生する虞れが多分にあり、冷却温度曲線から炭 素含有率を求める場合には測温結果が不正確となったり、成分分析用試料として は不健全なものとなる場合がある。 However, when molten steel is sampled in a metal container as a material for analysis, the molten steel is cooled rapidly and its temperature drops, so that the solubility of gases such as oxygen, nitrogen and hydrogen contained in the molten steel also drops sharply. As a result, there is a possibility that gas will be released in a short period of time, molten steel will be scattered during sampling, and bubbles will be generated in the sample.Therefore, when obtaining the carbon content from the cooling temperature curve, the temperature measurement result May be inaccurate or may be unhealthy as a sample for component analysis.
【０００４】 本考案の目的は、前述の問題点を改良し、温度を急冷することなく溶鋼試料を 採取できる溶鋼採取容器を提供することにある。An object of the present invention is to improve the above-mentioned problems and provide a molten steel sampling container capable of sampling a molten steel sample without quenching the temperature.
【０００５】[0005]
上述の目的を達成するための本考案の要旨は、溶鋼金属を採取する金属製容器 の内面に無機物から成る断熱材をコーティングしたことを特徴とする。 The gist of the present invention for achieving the above object is characterized in that an inner surface of a metal container for collecting molten steel metal is coated with a heat insulating material made of an inorganic material.
【０００６】[0006]
上述の構成を有する溶鋼採取容器は、金属製容器の内面に断熱材をコーティン グしているために、溶鋼が金属製容器に直接に接触せず、急冷されることがない 。 In the molten steel sampling container having the above-described configuration, the heat insulating material is coated on the inner surface of the metal container, so that the molten steel does not come into direct contact with the metal container and is not rapidly cooled.
【０００７】[0007]
本考案を図示の実施例に基づいて詳細に説明する。 図１は第１の実施例を示す断面図であって、１は略円筒形で上部に開口部を有 する有底の金属製測温容器であり、この測温容器１には熱電ユニット２を先端に 取り付けた保持管３が真横方向から接続されている。測温容器１の周囲に第１の 紙管４を装着し、測温容器１の入口部にはセラミック製の耐火物或いは金属製の 湯口５が嵌合されている。そして、測温容器１の内側には耐火モルタル層６がコ ーティングされている。また、湯口５の入口部には薄肉金属板から成るキャップ ７が被着されている。 The present invention will be described in detail with reference to the illustrated embodiment. FIG. 1 is a cross-sectional view showing a first embodiment, in which 1 is a bottomed metal temperature measuring container having a substantially cylindrical shape and an opening at the top, and the temperature measuring container 1 includes a thermoelectric unit 2 A holding tube 3 attached at the tip is connected from the lateral direction. A first paper tube 4 is attached around the temperature measuring container 1, and a ceramic refractory or a metal gate 5 is fitted to the inlet of the temperature measuring container 1. A refractory mortar layer 6 is coated inside the temperature measuring container 1. A cap 7 made of a thin metal plate is attached to the entrance of the sprue 5.
【０００８】 熱電ユニット２の周囲には、第１の紙管４と接続する第２の紙管８が装着され 、第１の紙管４と隙間がないように接続され、第２の紙管は保持管３の一部を包 囲している。熱電ユニット２には石英菅９中に封入した白金・白金ロジウムから 成る図示しない熱電対が検出端として用いられ、その先端部は測温容器１内の中 心部に位置するようになっている。A second paper tube 8 connected to the first paper tube 4 is mounted around the thermoelectric unit 2, and is connected to the first paper tube 4 so that there is no gap between the second paper tube and the second paper tube. Surround a part of the holding tube 3. In the thermoelectric unit 2, a thermocouple (not shown) made of platinum and platinum rhodium enclosed in a quartz tube 9 is used as a detection end, and its tip is located at the center of the temperature measuring container 1. .
【０００９】 この溶鋼採取容器を使用するには、保持管３に挿入した図示しないホルダを手 に持って、測温容器１を炉口から溶鋼中に浸漬する。測温容器１が鋼滓層を通り 溶鋼に達すると、キャップ７が溶融し溶鋼が湯口５を介して測温容器１内に流入 する。測温容器１を溶鋼中から持ち上げると同時に、測温容器１内で溶鋼の凝固 が始まるが、熱電ユニット２によりその熱起電力を測定することによって液相停 止値を検出することができ、炭素含有量を測定することが可能となる。To use this molten steel sampling container, a holder (not shown) inserted in the holding tube 3 is held by hand, and the temperature measuring container 1 is immersed in the molten steel through the furnace opening. When the temperature measuring container 1 reaches the molten steel through the steel slag layer, the cap 7 melts and the molten steel flows into the temperature measuring container 1 through the sprue 5. At the same time when the temperature measuring container 1 is lifted from the molten steel, the solidification of the molten steel starts in the temperature measuring container 1, but the liquid phase stop value can be detected by measuring the thermoelectromotive force of the thermoelectric unit 2. It becomes possible to measure the carbon content.
【００１０】 このような溶鋼採取容器を用いると、耐火モルタル層６を測温容器１の内面に コーティングしていることにより、金属製の測温容器１による溶鋼の急激な冷却 が阻止され、ガスの放出も少なく、内部に気泡等が残留することも少なく、炭素 含有率測定や測温誤差に影響を及ぼす虞れもない。When such a molten steel sampling container is used, the refractory mortar layer 6 is coated on the inner surface of the temperature measuring container 1 to prevent rapid cooling of the molten steel by the metal temperature measuring container 1 and The emission of carbon dioxide is small, bubbles are not left inside, and there is no fear of affecting the carbon content measurement or temperature measurement error.
【００１１】 図２は分析用試料を採取するための第２の実施例を示し、鉄製のルツボから成 る採取容器１１は紙管１２内に埋め込まれ、上方の開口部１３にはセラミックか ら成る湯口１４が連通され、底部は耐火モルタル１５により支持されている。こ の場合においても、採取容器１１の内部には耐火モルタル層１６が塗布されてい る。また、湯口１４の入口部にはキャップ１７が設けられている。FIG. 2 shows a second embodiment for collecting a sample for analysis. A collection container 11 made of an iron crucible is embedded in a paper tube 12 and an opening 13 in the upper part is made of ceramic. Formed of a sprue 14 communicating with each other, and a bottom portion thereof is supported by a refractory mortar 15. Also in this case, the refractory mortar layer 16 is applied to the inside of the collection container 11. A cap 17 is provided at the entrance of the sprue 14.
【００１２】 従って、この容器の場合においても、モルタル層１６のコーティングにより採 取容器１１内における溶鋼の冷却速度は遅くなり、溶鋼内のガスも徐々に放出さ れる結果、良好な分析用試料が得られる。Therefore, even in the case of this container, the cooling rate of the molten steel in the collection container 11 is slowed by the coating of the mortar layer 16 and the gas in the molten steel is gradually released, resulting in a good sample for analysis. can get.
【００１３】 なお、コーティングに使用する材料としては、ＳｉＯ2 、ＺｒＯ2 、ＭｇＯ、 Ａｌ2 Ｏ3 、長石、ＣａＯ等の無機物の粉末の単体又は混合したものを、バイン ダで泥状として塗布することが好ましい。また、Ａｌ、Ｔｉ等の脱酸性を有する 材料と混合して、溶鋼の脱酸効果を上げ採取に溶鋼を鎮静化することもできる。As a material used for coating, a powder or a mixture of inorganic powders such as SiO 2 , ZrO 2 , MgO, Al 2 O 3 , feldspar, and CaO is applied as a mud with a binder. It is preferable. Further, it can be mixed with a material having a deoxidizing property such as Al or Ti to enhance the deoxidizing effect of the molten steel and calm the molten steel for extraction.
【００１４】[0014]
以上説明したように本考案に係る溶鋼採取容器は、容器内に無機物から成る耐 火材をコーティングしているために、溶鋼の急冷を阻止し、溶鋼試料を健全な状 態で採取することができ、正確な測定値を求めることが可能となる。 As described above, since the molten steel sampling container according to the present invention is coated with a refractory material made of an inorganic substance in the container, quenching of the molten steel can be prevented and the molten steel sample can be collected in a sound state. Therefore, it is possible to obtain an accurate measurement value.
