Description

本発明は、製鉄所等において溶銑、溶鋼等の溶融金属の測温やサンプリングを行うための溶融金属のサンプリング装置に関する。   The present invention relates to a molten metal sampling apparatus for measuring temperature and sampling molten metal such as hot metal and molten steel in an ironworks or the like.

溶融金属のサンプリング装置は、例えば特許文献１に見られるように古くから知られてられている。この従来のサンプリング装置の概略構成を図３に示す。   A molten metal sampling apparatus has been known for a long time as disclosed in Patent Document 1, for example. A schematic configuration of this conventional sampling apparatus is shown in FIG.

同図に示すように、従来のサンプリング装置は、直線状のランス管２０を垂直方向に配置し、ランス管２０の先端に溶融金属の測温やサンプリングを行うプローブ２１を設けたもので、ランス管２０を昇降させることで、鍋２２内の溶融金属の測温やサンプリングを行うようにしたものである。したがって、ランス管２０は、真空槽２３を支持する真空槽台車２４や真空槽台車用梁２５、その他建屋の梁等と干渉しないように配置する必要があり、図３に示す従来のサンプリング装置では、ランス管２０先端のプローブ２１をプローブ着脱装置２６で交換するために、ランス管２０を真空槽台車２４の上方で傾動させるようにしている。この場合、ランス管２０を溶融金属面２７から真空槽台車２４の上方まで上昇させるためのストローク（通常６ｍ程度）が必要であり、結果として、サンプリング装置全体が大きくなってしまうという問題がある。
特公昭４９−４９５２０号公報 As shown in the figure, the conventional sampling apparatus has a linear lance tube 20 arranged in a vertical direction and a probe 21 for measuring the temperature of molten metal and sampling at the tip of the lance tube 20. By raising and lowering the tube 20, temperature measurement and sampling of the molten metal in the pan 22 are performed. Therefore, the lance tube 20 needs to be arranged so as not to interfere with the vacuum tank carriage 24, the vacuum tank carriage beam 25, and other building beams that support the vacuum chamber 23. In the conventional sampling apparatus shown in FIG. In order to replace the probe 21 at the tip of the lance tube 20 with the probe attaching / detaching device 26, the lance tube 20 is tilted above the vacuum tank carriage 24. In this case, a stroke (usually about 6 m) for raising the lance tube 20 from the molten metal surface 27 to above the vacuum tank carriage 24 is required, and as a result, there is a problem that the entire sampling device becomes large.
Japanese Patent Publication No.49-49520

本発明が解決しようとする課題は、装置全体をコンパクトにできる溶融金属のサンプリング装置を提供することにある。   The problem to be solved by the present invention is to provide a molten metal sampling apparatus capable of making the entire apparatus compact.

本発明の溶融金属のサンプリング装置は、鍋内の溶融金属面と同じ高さに設置された固定フレームに水平移動可能に取り付けられた走行フレームに、昇降ユニットを水平軸線周りに回転自在に配置し、この昇降ユニットに、前記走行フレームの移動軸線に対し直交する方向に往復動する昇降フレームを設け、この昇降フレームの一端にＬ字形状のランス管の基端を連結し、このランス管の先端にプローブを設けたことを特徴とするものである。 The molten metal sampling device according to the present invention is configured such that an elevating unit is rotatably arranged around a horizontal axis on a traveling frame attached to a fixed frame installed at the same height as a molten metal surface in a pan. , this lifting unit, wherein the lift frame to be reciprocated in a direction perpendicular to the axis of movement of the traveling frame is provided, connecting the proximal end of the lance tube of L-shaped at one end of the lifting frame, the tip of the lance tube This is characterized in that a probe is provided.

本発明は、水平移動する走行フレームを備えているので、サンプリング装置を溶融金属を入れる鍋の側方に配置することができ、その結果、ランス管の昇降ストロークが小さくて済むので、装置全体をコンパクトにすることができる。したがって、既設設備にも大規模な改造なしに設置することができる。   Since the present invention is provided with a traveling frame that moves horizontally, the sampling device can be arranged on the side of the pan in which the molten metal is put, and as a result, the lifting stroke of the lance tube can be reduced, so that the entire device can be It can be made compact. Therefore, it can be installed in existing facilities without any major modifications.

以下、本発明を図面に示す実施例に基づき本発明の実施の形態を説明する。   Embodiments of the present invention will be described below based on examples shown in the drawings.

図１は、本発明に係る溶融金属のサンプリング装置を示す斜視図である。同図において、固定フレーム１には、ガイドローラー２を介して走行フレーム３が水平方向に移動可能に取り付けられている。走行フレーム３にはチェーン４が取り付けられている。チェーン４の両端は、走行フレーム３の両端に固定されており、チェーン４の中間部分は、固定フレーム１に固定されたチェーンスプロケット５、５を介して、固定フレーム１に固定されたモーター６の駆動軸に取り付けられたチェーンスプロケット６ａに係止されている。これによって、モーター６を駆動させチェーンスプロケット６ａを回転させると、走行フレーム３が水平移動する。走行フレーム３を水平移動させるための機構は上記の構成に限定されず、例えばラック・ピニオン機構、シリンダー機構等を用いることもできる。   FIG. 1 is a perspective view showing a molten metal sampling apparatus according to the present invention. In the figure, a traveling frame 3 is attached to a fixed frame 1 through a guide roller 2 so as to be movable in the horizontal direction. A chain 4 is attached to the traveling frame 3. Both ends of the chain 4 are fixed to both ends of the traveling frame 3, and an intermediate portion of the chain 4 is connected to the motor 6 fixed to the fixed frame 1 via chain sprockets 5 and 5 fixed to the fixed frame 1. It is locked to a chain sprocket 6a attached to the drive shaft. Accordingly, when the motor 6 is driven and the chain sprocket 6a is rotated, the traveling frame 3 moves horizontally. The mechanism for horizontally moving the traveling frame 3 is not limited to the above configuration, and for example, a rack and pinion mechanism, a cylinder mechanism, or the like can be used.

走行フレーム３の先端側には、軸受７が設けられ、軸受７には回転軸８ａが装着され、回転軸８ａの先端に昇降ユニット８が固定されている。また、走行フレーム３には上下方向に伸縮する電動シリンダー９が配置されており、電動シリンダー９のシリンダーロッドがリンクを介して回転軸８ａに連結されている。これによって、電動シリンダー９を伸縮させると回転軸８ａが回転し、昇降ユニット８が回転軸８ａの軸線、すなわち水平軸線周りに回転する。   A bearing 7 is provided on the distal end side of the traveling frame 3, and a rotary shaft 8 a is attached to the bearing 7, and an elevating unit 8 is fixed to the distal end of the rotary shaft 8 a. The traveling frame 3 is provided with an electric cylinder 9 that expands and contracts in the vertical direction, and a cylinder rod of the electric cylinder 9 is connected to the rotary shaft 8a via a link. As a result, when the electric cylinder 9 is expanded and contracted, the rotating shaft 8a rotates, and the elevating unit 8 rotates around the axis of the rotating shaft 8a, that is, the horizontal axis.

昇降ユニット８には、昇降フレーム１０が、上述した走行フレーム３の移動軸線に対し直交する方向に移動可能に設けられている。昇降フレーム１０を移動させるため、昇降ユニット８にはモーター１１が設けられており、上述した走行フレーム３を水平移動させるための機構と同様の機構により、モーター１１を駆動させることで昇降フレーム１０が移動するようになっている。   The elevating unit 8 is provided with an elevating frame 10 so as to be movable in a direction orthogonal to the movement axis of the traveling frame 3 described above. In order to move the lifting frame 10, the lifting unit 8 is provided with a motor 11, and the lifting frame 10 is driven by driving the motor 11 by a mechanism similar to the mechanism for horizontally moving the traveling frame 3 described above. It is supposed to move.

昇降フレーム１０に一端には３次元のＬ字形状としたランス管１２が連結されており、ランス管１２の先端には、溶融金属の測温やサンプリング温度測定を行うプローブ１３が装着されている。   A lance tube 12 having a three-dimensional L-shape is connected to the elevating frame 10 at one end, and a probe 13 for measuring the temperature of the molten metal or measuring the sampling temperature is attached to the tip of the lance tube 12. .

以上、説明したように、プローブ１３は、走行フレーム３の水平移動により図１中のＸ１−Ｘ２方向に移動し、昇降フレーム１０の往復動によりＹ１−Ｙ２方向に移動し、昇降ユニット８の回転によりＺ１−Ｚ２方向に回転する。すなわち、プローブ１３は、以上の動作の組み合わせによって３次元方向に移動自在である。 As described above, the probe 13 moves in the X 1 -X 2 direction in FIG. 1 by the horizontal movement of the traveling frame 3, and moves in the Y 1 -Y 2 direction by the reciprocating movement of the lifting frame 10. The unit 8 rotates in the Z 1 -Z 2 direction. That is, the probe 13 is movable in the three-dimensional direction by a combination of the above operations.

図２には、図１のサンプリング装置の使用形態を示す。同図に示す使用形態は、製鉄所の製鋼工程における溶鋼のサンプリング装置として適用したものである。   FIG. 2 shows a usage pattern of the sampling device of FIG. The usage pattern shown in the figure is applied as a molten steel sampling device in a steelmaking process at an ironworks.

図２に示すように、サンプリング装置の固定フレーム１は鍋２２内の溶鋼面２７とほぼ同じ高さに設置されており、プローブ１３を３次元で運動させることにより溶鋼内に挿入し測温やサンプリングを行う（図２の状態）。このとき、ランス管１２が鍋２２や真空槽２３、真空槽台車２４、真空槽台車用梁２５などと接触して干渉しないように、ランス管１２は上述のように３次元のＬ字形状とされている。サンプリングが終了したら、昇降フレーム１０を上昇させてプローブ１３を溶鋼内から取り出す。その後、昇降ユニット８を回転動作させ、走行フレーム３を水平移動させることにより、所定の初期位置に復帰させる。   As shown in FIG. 2, the fixed frame 1 of the sampling device is installed at almost the same height as the molten steel surface 27 in the pan 22, and is inserted into the molten steel by moving the probe 13 in a three-dimensional manner. Sampling is performed (state shown in FIG. 2). At this time, the lance tube 12 has a three-dimensional L-shape as described above so that the lance tube 12 does not contact and interfere with the pan 22, the vacuum chamber 23, the vacuum chamber carriage 24, the vacuum chamber carriage beam 25, or the like. Has been. When the sampling is completed, the lifting frame 10 is raised and the probe 13 is taken out from the molten steel. Thereafter, the elevating unit 8 is rotated and the traveling frame 3 is moved horizontally to return to a predetermined initial position.

以上、本発明のサンプリング装置では、プローブ１３が３次元方向に移動自在であるため、その昇降ストロークも小さくて済む。したがって、図３に示した従来のものに比べ、装置全体を格段にコンパクト化することができる。   As described above, in the sampling device of the present invention, since the probe 13 is movable in the three-dimensional direction, the lifting stroke thereof can be small. Therefore, the entire apparatus can be made much more compact than the conventional apparatus shown in FIG.

本発明は、溶鋼を始めとした、あらゆる溶融金属の測温やサンプリングを行うための装置として利用可能である。   INDUSTRIAL APPLICABILITY The present invention can be used as an apparatus for measuring the temperature and sampling of all molten metals including molten steel.
