The lead wire connected to the main body 24a is connected to the connector C.
一方，脱酸剤Ａが受鋼室１０内に装填される。サブランスなどの昇降装置によってプローブ本体１が溶融金属に向かって下降すると，プローブ本体１はスラグ層を通過して溶融金属浴の中に浸漬される。よって，第２温度センサ２４の金属キャップ２４ｃが消失して溶融金属の温度を測定する。また，外部枝管４が消失して導入口３ａ，３ｂが開放されるとプローブ本体１の内部に溶融金属が導入された後，溶融金属は受鋼室１０及び採取室１８に向かって移動する。 On the other hand, the deoxidizer A is loaded into the steel receiving chamber 10. When the probe body 1 is lowered toward the molten metal by a lifting device such as a sub lance, the probe body 1 passes through the slag layer and is immersed in the molten metal bath. Therefore, the metal cap 24c of the second temperature sensor 24 disappears and the temperature of the molten metal is measured. Further, when the outer branch pipe 4 disappears and the introduction ports 3a and 3b are opened, the molten metal is introduced into the probe main body 1, and then the molten metal moves toward the steel receiving chamber 10 and the sampling chamber 18. .
受鋼室１０に導入された溶融金属は受鋼室１０に装填された脱酸剤Ａを介して効率的に脱酸され，受鋼室１０に充填されてから直ちに凝固を開始して周囲から次第に固形化され，受鋼室１０のほぼ中心，すなわち熱均衡がよい位置に第１温度センサ２２の測温部２２ｃを配置して温度測定値の平坦部を得るための測温が行われる。 The molten metal introduced into the steel receiving chamber 10 is efficiently deoxidized via the deoxidizer A loaded in the steel receiving chamber 10, and immediately after the steel receiving chamber 10 is filled, solidification starts and the surroundings start. Temperature measurement is performed to obtain a flat portion of the temperature measurement value by gradually placing the temperature measurement unit 22c of the first temperature sensor 22 in the center of the steel receiving chamber 10, that is, at a position with good thermal balance.
受鋼室１０に溶融金属が導入されると，溶融金属が凝固される過程で導入温度と凝固温度の差によってピーク（過熱度）が発生し，凝固潜熱によって凝固温度が一定時間安定に維持される凝固温度平坦部が生成される。溶鋼などの溶融金属内に存在する炭素の量は凝固温度データを介して推定され，溶融金属の凝固温度が一定の数値を維持する凝固温度平坦部を介して推定される。凝固温度平坦部は溶融金属の凝固潜熱放出の安定度及び持続時間によって影響を受け，また，実質的に安定度及び持続時間は溶融金属の温度及び成分，受鋼室１０の形態及び材質に応じて変化する。 When molten metal is introduced into the steel receiving chamber 10, a peak (superheat degree) is generated due to the difference between the introduction temperature and the solidification temperature in the process of solidifying the molten metal, and the solidification temperature is stably maintained for a certain time by the solidification latent heat. A solidified temperature flat portion is generated. The amount of carbon present in a molten metal such as molten steel is estimated through solidification temperature data, and is estimated through a solidification temperature flat portion where the solidification temperature of the molten metal maintains a constant value. The solidification temperature plateau is affected by the stability and duration of the solidification latent heat release of the molten metal, and substantially the stability and duration depend on the temperature and composition of the molten metal, the form and material of the steel receiving chamber 10. Change.
一方，既知の溶融金属プローブの場合，溶融金属の冷却不均一のため受鋼室１０内で局部的な相変態が生じて凝固温度平坦部が傾くか，凝固開始時点が遅くなって凝固温度を正確に感知することができない問題がある。 On the other hand, in the case of the known molten metal probe, because of the uneven cooling of the molten metal, a local phase transformation occurs in the steel receiving chamber 10 and the solidification temperature flat part is inclined, or the solidification start time is delayed and the solidification temperature is decreased. There is a problem that cannot be accurately detected.
特に，迅速出鋼操業（ＱＤＴ：Quick Direct Tapping）のように吹錬操業の後半部に高い溶鋼温度のため高過熱度の溶鋼が導入され，このような溶鋼のため凝固温度平坦部が遅く形成されて測定時間内の正確な炭素量の推定が難しいか，凝固時間が長くなることによる冷却不均衡が発生して凝固温度平坦部が緩慢に形成される問題が発生する。すなわち，溶融金属の過熱度が大きすぎる場合，温度が漸進的に減少して凝固温度平坦部が生成されず，それによって制御部が演算ロジック（logic）を介して凝固温度開始以前の温度を凝固温度と誤って判断する恐れがある。この場合には，炭素の推定値は低くなり，これは測定エラー又は測定の正確性の低下に繋がる。よって，溶融金属の凝固時間を短縮する必要がある。 In particular, high superheated molten steel was introduced in the latter half of the blow smelting operation as in the case of quick direct tapping (QDT) due to the high molten steel temperature. As a result, it is difficult to accurately estimate the amount of carbon within the measurement time, or a problem arises in that a solidification temperature flat portion is slowly formed due to a cooling imbalance caused by a long solidification time. That is, when the superheat degree of the molten metal is too large, the temperature gradually decreases and the solidification temperature flat part is not generated, so that the control part solidifies the temperature before the solidification temperature start through the logic. There is a risk of misjudging it as temperature. In this case, the estimate of carbon is low, which leads to measurement errors or reduced measurement accuracy. Therefore, it is necessary to shorten the solidification time of the molten metal.
受鋼室１０に溶融金属が導入されると，導入された溶融金属は熱エネルギーを伝導，対流，輻射によって外部に発散する。これをクボリノフ（Chvorinov）の式で示すと以下のようである。
ｔf＝ｃ（体積（Ｖc）／表面積（Ａc））2
（ｔf＝凝固時間，Ｖc＝体積，Ａc＝表面積，ｃ＝常数）
When molten metal is introduced into the steel receiving chamber 10, the introduced molten metal radiates the heat energy to the outside by conduction, convection, and radiation. This is expressed by the formula of Chvorinov as follows.
t f = c (volume (V c ) / surface area (A c )) 2
(T f = solidification time, V c = volume, A c = surface area, c = constant)
前記式から，凝固時間を短縮する理想的な受鋼室１０の形状は球状よりは四角柱などの多角柱形状であり，測温部２２ｃの位置が受鋼室１０の中心部に位置する場合，直方体よりは正方形又は円柱が表面積を十分に確保することができるため均質凝固核形成（homogeneous nucleation）に容易である。 From the above equation, the ideal shape of the steel receiving chamber 10 for shortening the solidification time is a polygonal column shape such as a square column rather than a spherical shape, and the temperature measuring portion 22c is located at the center of the steel receiving chamber 10. ， Square or cylinder can secure a sufficient surface area than rectangular parallelepiped, so it is easier for homogeneous nucleation.
しかし，シェルコンテナ１０７の内部の空間的制約のため受鋼室１０の形状に制約があり，凝固温度平坦部を確保するためには受鋼室１０の容積が一定の大きさ以上であるべきであるため，直方体が最適化された設計に当たる。 However, there is a restriction on the shape of the steel receiving chamber 10 due to the space restriction inside the shell container 107, and the volume of the steel receiving chamber 10 should be a certain size or more in order to secure a solidification temperature flat portion. Therefore, the rectangular parallelepiped is an optimized design.
前記式によると，凝固時間は体積比（モジュラス＝体積／表面積）の２乗に比例するため，凝固時間を短縮するためには体積比を減らすべきである。その他には受鋼部の表面積を増加する必要があり，特に後述する温度センサ２２ａの測温部２２ｃから離間した長手方向に短い表面に波状のパターンやエンボスパターン処理をして熱発散を加速することで凝固時間を短縮することができる。受鋼室１０は直方体であるため，受鋼湯道９及び第１設置空間１４に隣接した断面以外に受鋼室１０の長さ方向に沿って形成された長手方向に短い表面及び長手方向に長い表面を有し，受鋼室１０内に充填された溶融金属の中は長手方向に短い表面及び長手方向に長い表面を介して熱を発散し凝固される。この際，温度センサ２２ａの測温部２２ｃは受鋼室１０の中心部に位置し，前記長手方向に短い表面は長手方向に長い表面に比べて表面積が小さいだけではなく，受鋼室１０の中心部から離間しているため，前記長手方向に短い表面を介した溶融金属の熱発散は前記長い表面に比べて遅延される恐れがある。そこで，パターン処理を介して表面積を増加する必要がある。また，受鋼室１０の体積を減らして凝固試料の大きさを約２０％以上減小している。 According to the above formula, since the solidification time is proportional to the square of the volume ratio (modulus = volume / surface area), the volume ratio should be reduced in order to shorten the solidification time. In addition, it is necessary to increase the surface area of the steel receiving part, and in particular, a heat wave is accelerated by performing a wave-like pattern or an embossing pattern process on a short surface in the longitudinal direction spaced from a temperature measuring part 22c of a temperature sensor 22a described later. Thus, the coagulation time can be shortened. Since the steel receiving chamber 10 is a rectangular parallelepiped, in addition to the cross section adjacent to the steel receiving runner 9 and the first installation space 14, the surface formed in the longitudinal direction of the steel receiving chamber 10 has a short surface and the longitudinal direction. The molten metal having a long surface and filled in the steel receiving chamber 10 dissipates heat through a short surface in the longitudinal direction and a long surface in the longitudinal direction to be solidified. At this time, the temperature measuring portion 22c of the temperature sensor 22a is located at the center of the steel receiving chamber 10, and the surface short in the longitudinal direction has a smaller surface area than the surface long in the longitudinal direction. Due to the separation from the center, the heat dissipation of the molten metal through the short surface in the longitudinal direction may be delayed compared to the long surface. Therefore, it is necessary to increase the surface area through pattern processing. Further, the volume of the steel receiving chamber 10 is reduced to reduce the size of the solidified sample by about 20% or more.
図４は図１に示すシェルコンテナの比較例を示す図であり，図５は，図４に示すシェルコンテナの内部で凝固された試料を示す図である。図６は，図１に示すシェルコンテナの第１実施例を示す図であり，図７は，図６に示すシェルコンテナの内部で凝固された試料を示す図である。図８は図１に示すシェルコンテナの第２実施例を示す図であり，図９は，図８に示すシェルコンテナの内部で凝固された試料を示す図である。 4 is a view showing a comparative example of the shell container shown in FIG. 1, and FIG. 5 is a view showing a sample solidified inside the shell container shown in FIG. 6 is a view showing a first embodiment of the shell container shown in FIG. 1, and FIG. 7 is a view showing a sample solidified inside the shell container shown in FIG. FIG. 8 is a view showing a second embodiment of the shell container shown in FIG. 1, and FIG. 9 is a view showing a sample solidified inside the shell container shown in FIG.
図５に示す試料Ｓ1は図４の受鋼室１０と実質的に一致する形状であり，両側面ｆ1は基準面の両側に配置されて互いに対向する内面に当たる。図７に示す試料Ｓ2は図６の受鋼室１０と実質的に一致する形状であり，両側面ｆ2，ｆ2は基準面の両側に配置されて互いに対向する内面に当たる。すなわち，図６の受鋼室１０は内面に波状の凹凸パターンが形成されるため，試料Ｓ2は波状の凹凸パターンｐ2を有する。図９に示す試料Ｓ3は，図８の受鋼室１０と実質的に一致する形状であり，両側面ｆ3，ｆ3は，基準面の両側に配置されて互いに対向する内面に当たる。すなわち，図８の受鋼室１０は内面に円形の突起を有するため，試料Ｓ3は円形の凹溝パターンｐ3を有する。 A sample S 1 shown in FIG. 5 has a shape substantially coincident with the steel receiving chamber 10 shown in FIG. 4, and both side surfaces f 1 are arranged on both sides of the reference surface and contact the inner surfaces facing each other. The sample S 2 shown in FIG. 7 has a shape substantially coincident with the steel receiving chamber 10 shown in FIG. 6, and both side surfaces f 2 and f 2 are arranged on both sides of the reference surface and contact the inner surfaces facing each other. That is, since the corrugated uneven pattern is formed on the inner surface of the steel receiving chamber 10 in FIG. 6, the sample S 2 has the corrugated uneven pattern p 2 . A sample S 3 shown in FIG. 9 has a shape substantially coinciding with the steel receiving chamber 10 of FIG. 8, and both side surfaces f 3 and f 3 are arranged on both sides of the reference surface and correspond to inner surfaces facing each other. That is, since the steel receiving chamber 10 in FIG. 8 has a circular protrusion on the inner surface, the sample S 3 has a circular concave groove pattern p 3 .
図４乃至図９に示す受鋼室をまとめると下記表１のようである。
前記表１によると，モジュラスが４〜４．５である際に波形安定性及び成分推定の正確度が優秀であった。４．０未満である場合，凝固温度平坦部の確保が難しいほどに速い冷却を示しており，４．５以上である場合，冷却遅延のため局部的に相平衡条件が形成されて測定値の信頼度が下落した。 According to Table 1, when the modulus is 4 to 4.5, the waveform stability and the accuracy of component estimation are excellent. If it is less than 4.0, it indicates that the cooling is so fast that it is difficult to ensure a flat part of the solidification temperature. If it is 4.5 or more, a phase equilibrium condition is formed locally due to cooling delay, and the measured value Reliability decreased.
一方，図６及び図８は波状の凹凸パターン又は凹溝状の凹凸パターンを示しているが，本発明は凹凸パターンの形状に制限されず，波状又は凹溝状が混在するか他の形態の凹凸パターンが形成されてもよい。 On the other hand, FIG. 6 and FIG. 8 show a wavy uneven pattern or a concave-convex pattern, but the present invention is not limited to the shape of the concave-convex pattern. An uneven pattern may be formed.
図１０及び図１１は，第１温度センサを介して測定した溶融金属の温度を比較した結果を示すグラフである。図１０乃至図１１の実線（１）は溶融金属の温度を示し，溶融金属が受鋼室１０内に導入されると第１温度センサ２２を介した測定波形は，高温の溶融金属のため持続的に上昇してから相平衡が行われた状態で凝固が開始されて凝固温度を示す。図１０に示す比較例の場合，局部的に相平衡条件が形成されて傾いた形態の凝固温度を示すが，図１１に示す実施形態２の場合には測定波形が比較的水平状態である凝固温度を示している。 FIG.10 and FIG.11 is a graph which shows the result of having compared the temperature of the molten metal measured through the 1st temperature sensor. The solid line (1) in FIGS. 10 to 11 indicates the temperature of the molten metal, and when the molten metal is introduced into the steel receiving chamber 10, the measurement waveform through the first temperature sensor 22 is sustained because of the high temperature molten metal. Solidification is started in a state where phase equilibration has been performed after the temperature rises, and indicates the solidification temperature. In the case of the comparative example shown in FIG. 10, the solidification temperature is in a tilted state with a locally formed phase equilibrium condition. In the case of the second embodiment shown in FIG. 11, the measurement waveform is in a relatively horizontal state. Indicates temperature.
図１２及び図１３は，成分分析及び凝固温度を介した推定によって溶融金属内の炭素量を示すグラフである。横軸は回収された試料の炭素成分分析（ＣＡ：Carbon Analysis）による値であり，縦軸は炭素推定値を示すグラフである。図１２に示す比較例の場合，実線（横軸と縦軸の値が一致する場合）から一定範囲（±０．０６％の範囲）を示す２本の点線間を逸脱している。一方，図１３に示す実施例２の場合，実線から一定範囲（±０．０６％の範囲）内に位置するため安定的な結果を示している。 12 and 13 are graphs showing the amount of carbon in the molten metal by component analysis and estimation via the solidification temperature. The horizontal axis is a value obtained by carbon analysis (CA) of the collected sample, and the vertical axis is a graph showing the estimated carbon value. In the case of the comparative example shown in FIG. 12, the distance between the two dotted lines indicating a certain range (± 0.06% range) deviates from the solid line (when the values on the horizontal and vertical axes match). On the other hand, the second embodiment shown in FIG. 13 shows a stable result because it is located within a certain range (± 0.06% range) from the solid line.
一方，溶融金属が受鋼湯道９を介して受鋼室１０内に導入される過程において，受鋼湯道９の角が大きい場合，受鋼湯道９の角部で溶融金属が衝突し渦巻きを形成する渦流（vortex）現象が発生して乱流流動が形成され，それによって空気及びガスの混入が発生する恐れがある。よって，受鋼湯道９の角部９ｒをラウンド処理（湾曲した形状と）することが好ましく，該部を介して渦流現象を防止することができる。 On the other hand, in the process where the molten metal is introduced into the steel receiving chamber 10 via the steel receiving runner 9, when the corner of the steel receiving runner 9 is large, the molten metal collides with the corner of the steel receiving hot runner 9. A vortex phenomenon that forms a vortex is generated and a turbulent flow is formed, which may cause air and gas contamination. Therefore, it is preferable to round the corner portion 9r of the receiving steel runner 9 (with a curved shape), and the vortex phenomenon can be prevented through the portion.
また，図６に示すように，受鋼室１０と採取室１８はシェルコンテナ１０７の縦方向に沿って重ならないように配置されるが，採取湯道１１はシェルコンテナ１０７の縦方向に沿って受鋼室１０と重なって配置される。よって，採取湯道１１を介して移動する溶融金属の高熱が受鋼室１０，特に受鋼室１０に配置された第１温度センサ２２の測温部２２ｃに影響を及ぼす恐れがあり，それによって凝固温度を正確に測定することができない。よって，シェルコンテナ１０７の縦方向に沿って受鋼室１０と重なる採取湯道１１の角部をラウンド処理して受鋼室１０と採取室１８との間に位置する隔壁の厚さを，採取室１８から遠くなる方向に増加し，前記壁厚を介して採取湯道１１を流れる溶融金属の高熱が測温部２２ｃに及ぼす影響を最小化することができる。また，採取湯道１１の角部がラウンド処理された場合，溶融金属が導入される過程で発生する渦流現象を最小化することができる。 In addition, as shown in FIG. 6, the steel receiving chamber 10 and the sampling chamber 18 are arranged so as not to overlap with each other in the vertical direction of the shell container 107, but the sampling runner 11 extends along the vertical direction of the shell container 107. It is arranged so as to overlap with the steel receiving chamber 10. Therefore, the high heat of the molten metal moving through the sampling runner 11 may affect the temperature measuring section 22c of the first temperature sensor 22 arranged in the steel receiving chamber 10, particularly the steel receiving chamber 10, thereby The solidification temperature cannot be measured accurately. Therefore, the corner portion of the sampling runner 11 that overlaps the steel receiving chamber 10 along the longitudinal direction of the shell container 107 is rounded, and the thickness of the partition located between the steel receiving chamber 10 and the sampling chamber 18 is sampled. It is possible to minimize the influence of the high heat of the molten metal that increases in the direction farther from the chamber 18 and flows through the sampling runner 11 through the wall thickness on the temperature measuring unit 22c. Further, when the corner portion of the sampling runner 11 is rounded, the eddy current phenomenon that occurs in the process of introducing the molten metal can be minimized.
また，上述した溶融金属プローブの可用範囲（すなわち，溶融金属の凝固温度の測定範囲）を拡張するために過熱度が低い溶融金属が導入される場合にも凝固温度を効果的に測定すべきであり，そのために溶融金属の導入を早くすることで，溶融金属の温度降下を最小化して，受鋼室１０に到達した溶融金属の温度を電炉内の溶融金属の温度と近似させることが好ましい。 Also, the solidification temperature should be measured effectively when a molten metal with a low superheat is introduced to expand the usable range of the molten metal probe described above (ie, the measurement range of the solidification temperature of the molten metal). Therefore, it is preferable to minimize the temperature drop of the molten metal by accelerating the introduction of the molten metal, and to approximate the temperature of the molten metal reaching the steel receiving chamber 10 to the temperature of the molten metal in the electric furnace.
よって，受鋼湯口３ａ（及び／又は開口３３ａ）の直径（図４中符号ｄ）を最適化する必要があり，実験結果から約２０〜２５mmである際に溶融金属の充填性能が良好であった。約２０mm未満であれば溶融金属が受鋼室１０内に十分に充填される前に凝固が進行されて充填性能が低下しており，約２５mmを超過すれば受鋼室１０内に充填された溶融金属が逆流して充填性能がかえって低下する現象が発生する。図１４及び図１５は受鋼湯口の直径による試料の状態を示す写真であり，図１４の受鋼湯口は直径が１７mmで，図１５の受鋼湯口は直径が２４．５mmである。 Therefore, it is necessary to optimize the diameter (symbol d in FIG. 4) of the steel receiving spout 3a (and / or the opening 33a). From the experimental results, the molten metal filling performance is good. It was. If it is less than about 20 mm, solidification progresses before the molten metal is sufficiently filled in the steel receiving chamber 10 to deteriorate the filling performance. If it exceeds about 25 mm, the steel receiving chamber 10 is filled. A phenomenon occurs in which the molten metal flows backward to lower the filling performance. 14 and 15 are photographs showing the state of the sample according to the diameter of the steel receiving spout. The steel receiving spout in FIG. 14 has a diameter of 17 mm, and the steel receiving spout in FIG. 15 has a diameter of 24.5 mm.
また，受鋼室１０及び採取室１８は相対的に大きな鉄静圧（ferro-static pressure）を多く受けるようにするためにそれぞれ隔離（又は分離）された受鋼湯口３ａと採取湯口３ｂを有する。受鋼湯口３ａと採取湯口３ｂが一つに統合される場合，溶融金属が受鋼室１０及び採取室に分離されてそれぞれ流動する過程で渦巻きを形成する渦流現象が発生して乱流流動が形成されるため，溶融金属の導入が容易ではないためである。特に，受鋼湯道９は導入口３ａから第１温度センサ２２から遠くなる方向に傾斜し，シェルコンテナ１０７の横断面と受鋼湯道９が成す傾斜角度θは約２０乃至６０度であることが好ましい。約２０度未満であれば受鋼湯口３ａが溶融金属プローブの先端から遠くなってスラグが導入される可能性が高くなり，約６０度を超過すれば大きい傾斜のため溶融金属の充填性能が低下する恐れがある。 In addition, the steel receiving chamber 10 and the sampling chamber 18 have a steel receiving gate 3a and a sampling gate 3b that are isolated (or separated), respectively, so as to receive a relatively large amount of ferro-static pressure. . When the receiving steel spout 3a and the sampling spout 3b are integrated into one, a vortex phenomenon that forms a vortex is generated in the process in which the molten metal is separated into the receiving steel chamber 10 and the sampling chamber, respectively, and the turbulent flow is generated. This is because it is not easy to introduce molten metal. In particular, the receiving steel runner 9 is inclined away from the introduction port 3a in the direction away from the first temperature sensor 22, and the inclination angle θ formed by the cross section of the shell container 107 and the receiving steel runner 9 is about 20 to 60 degrees. It is preferable. If it is less than about 20 degrees, there is a high possibility that the receiving steel spout 3a is far from the tip of the molten metal probe and slag is introduced, and if it exceeds about 60 degrees, the filling performance of molten metal decreases due to the large inclination. There is a fear.
また，受鋼湯口３ａ及び採取湯口３ｂは溶融金属プローブの先端から約２００mm以内にあることが好ましい。すなわち，溶融金属プローブの先端から受鋼湯口３ａまでの距離Ｄは約２００mm以下に当たる。これは通常溶融金属プローブの浸漬深さを約５００〜６００mm程度に設定する際，試料の健全性及び充填性能を確保するためである。 Moreover, it is preferable that the receiving steel gate 3a and the sampling gate 3b are within about 200 mm from the tip of the molten metal probe. That is, the distance D from the tip of the molten metal probe to the receiving steel gate 3a corresponds to about 200 mm or less. This is to ensure the soundness and filling performance of the sample when the immersion depth of the molten metal probe is normally set to about 500 to 600 mm.
一方，採取室１８に向かって移動した溶融金属は採取容器２３内で凝固されて機器分析などの分析のための凝固試料として提供される。溶融金属浴から引き揚げられたプローブ本体１に衝撃を加えると，シェルコンテナ１０７が衝撃によって崩壊され，採取室１８を破壊して採取容器２３を容易に分離することができる。次に，採取容器２３は移送装置によって移送されて機器分析などの分析に提供される。 On the other hand, the molten metal moved toward the collection chamber 18 is solidified in the collection container 23 and provided as a solidified sample for analysis such as instrumental analysis. When an impact is applied to the probe main body 1 drawn up from the molten metal bath, the shell container 107 is collapsed by the impact, and the collection chamber 18 can be destroyed and the collection container 23 can be easily separated. Next, the collection container 23 is transferred by a transfer device and provided for analysis such as instrument analysis.
