Description

この発明は、特許請求項１の上位概念の特徴事項をもつ金属を連続鋳造する金型管に関する。 The present invention relates to a mold pipe for continuously casting a metal having the features of the superordinate concept of claim 1.

高い溶融点を備える鋼或いは他の金属から形状を鋳造する銅或いは銅合金製の管状金型は先行技術において数倍に記載されていた。金型管は通常には水平横断面において金型管の内部円錐形状に基づいて連続成形方向に増大する均一な壁厚を有する。この内部円錐形状はストランドの凝固状態やストランドパラメータに適合している。連続鋳造材料の始まる凝固の直後に、つまりメニスカスの直接下部に、それは横断面にわたり三次元に鋳造された熱流出に基づいて鋳造ストランドの強く異なって鋳造された冷却状態を生じる。金型管の隅において幾何学的関係に基づいて特に大きい熱量が流出されるから、そこに特に強いストランド凝固殻成長とそれに伴う特に強い収縮が生じる。金型管の側壁には、熱流出は、ここで同時により高い熱流が現れるにもかかわらず、通常には僅かである。局部的に異なる冷却の結果は、不均一なストランド凝固殻成長であり、それはストランド凝固殻に材料応力と亀裂を生じて、それによってストランド湯漏れの危険が高まる。   Tubular molds made of copper or copper alloys that cast shapes from steel or other metals with high melting points have been described several times in the prior art. The mold tube usually has a uniform wall thickness that increases in the continuous molding direction on the horizontal cross section based on the internal cone shape of the mold tube. This internal cone shape is adapted to the solidification state of the strand and the strand parameters. Immediately after the initial solidification of the continuous casting material, ie directly below the meniscus, it results in a strongly differently cast cooling state of the cast strands based on the heat flow cast in three dimensions across the cross section. A particularly large amount of heat flows out at the corners of the mold tube based on the geometric relationship, which results in particularly strong strand solidification shell growth and associated strong contraction. On the side wall of the mold tube, the heat outflow is usually slight, although a higher heat flow appears at the same time here. The result of locally different cooling is non-uniform strand solidification shell growth, which creates material stresses and cracks in the strand solidification shell, thereby increasing the risk of strand leakage.

出来るだけ均質熱搬出を得て、それにより高い鋳造出力の前提条件を作り出すために、既に一連の提案が成されていた。例えば、独逸特許出願公開第３６２１０７３号明細書（特許文献１）から、弓状側面のみが冷却溝を備えて、これに対して隅領域は冷却溝を備えていない金型が公知である。冷却は特にメニスカスの領域において高められた、それは独逸特許出願公開第３４１１３５９号明細書（特許文献２）と日本特開２００３−３１１３７７公報（特許文献５）にも記載されている。欧州特許第１４６８７６０号明細書（特許文献３）も、冷却出力の改善と鋳造速度の上昇とを取り扱っていて、冷却通路は銅管の外表面の６５％〜９５％を必要とし、この場合に銅管は同時に全周辺にわたり且つ実質的に全長にわたり支持外被を備えている。垂直に振動する連続鋳造型では、逸特許第１９５８１５４７号明細書（特許文献３）が内面に窪み或いは下降部を備えることを提案し、その窪み或いは下降部は安定な運転状態で把握されたメニスカスの下部の１５ｍｍから２００ｍｍまでの距離に配置されている。それによって同様に安定な鋳造がより早い速度で可能とされる。すべてのこれらの初めは理想的熱流分布の十分な算出を受けられない。
独逸特許出願公開第３６２１０７３号明細書 独逸特許出願公開第３４１１３５９号明細書 欧州特許第１４６８７６０号明細書 逸特許第１９５８１５４７号明細書 日本特開２００３−３１１３７７公報 日本特開平０３−０００４５３号公報 A series of proposals have already been made in order to obtain as much heat output as possible and thereby create the preconditions for high casting power. For example, from German Patent Application Publication No. 3621073 (Patent Document 1), a mold is known in which only the arcuate side surface is provided with cooling grooves, whereas the corner region is not provided with cooling grooves. Cooling was enhanced particularly in the area of the meniscus, which is also described in German Patent Application Publication No. 3411359 (Patent Document 2) and Japanese Patent Application Laid-Open No. 2003-311377 (Patent Document 5) . EP 1468760 (Patent Document 3) also deals with improving cooling output and increasing casting speed, and the cooling passage requires 65% to 95% of the outer surface of the copper tube, in this case The copper tube is simultaneously provided with a support jacket over the entire periphery and substantially over the entire length. In a continuous casting mold that vibrates vertically, Hei Patent No. 19581547 (Patent Document 3) proposes that the inner surface is provided with a depression or a descending part, and the depression or the descending part is grasped in a stable operating state. It is arranged at a distance of 15 mm to 200 mm at the lower part of. This likewise allows stable casting at a faster speed. All these beginnings do not receive a sufficient calculation of the ideal heat flow distribution.

この発明の課題は、先行技術から出発して、ストランド冷却の均質性が、成果において高い鋳造出力と良いストランド品質を実現するために、さらに上昇されて、そのうえ、金型管壁内部の応力を減少させるのに役立つ金型管を用意することである。 The object of the present invention is that, starting from the prior art, the homogeneity of the strand cooling is further increased in order to achieve a high casting power and good strand quality in the results, as well as the stress inside the mold tube wall. It is to prepare a mold tube that helps to reduce.

この課題は、特許請求項１の特徴部分を備える金型管により解決される。 This problem is solved by a die tube with the characterizing part of patent claim 1.

この発明の好ましい構成は、従属請求項の対象である。   Preferred configurations of the invention are the subject matter of the dependent claims.

この発明による金型管では、金型管の冷却作用がストランドの熱提供に一致して、それにより均一な冷却を生じるように最適化されることが、本質である。これは、冷却溝の深さと幅が金型管の側壁の中心で最大であり、側壁の隅領域の方向に減少されることによって達成される。冷却溝の横断面が側壁の中心領域では側壁の縁領域より大きいことが重大である。この発明による技術や形式において冷却溝を設けることによって側壁に生じる最高比較応力が明らかに減少され得ることがわかった。理想的弾性剛性算定は比較応力が５０４ＭＰａから３４８ＭＰａまでの３０％以上だけ減少され得ることを確認した。この主張は、１３０×１３０ｍｍの金型横断面に関連し、金型管は溝なしにこの発明により構成された溝を備える金型管に対向配置されている。金型管内のこの技術で達成された応力の減少は好ましくは耐用期間に影響を与えて、金型管の熱条件付きゆがみを減少させる。この発明による金型管はこの算出において各側壁には８個の溝を鋳造方向に延びる２００ｍｍの長さをもつ５ｍｍの間隔に有する。中間溝は５ｍｍの深さを有し、それに対して外側溝は１２ｍｍ或いは８ｍｍの幅にて４ｍｍの深さを有する。側壁の隅領域には、溝が配置されていない。 In the mold tube according to the invention, it is essential that the cooling action of the mold tube is optimized to match the heat provision of the strands and thereby produce a uniform cooling. This is achieved by the cooling groove depth and width being greatest at the center of the mold tube sidewall and being reduced in the direction of the corner area of the sidewall. It is important that the cross-section of the cooling groove is larger in the central region of the side wall than in the edge region of the side wall. It has been found that by providing cooling grooves in the technique and type according to the present invention, the maximum comparative stress produced on the side walls can be clearly reduced. Ideal elastic stiffness calculations confirmed that the comparative stress can be reduced by more than 30% from 504 MPa to 348 MPa. This allegation relates to a mold cross section of 130 × 130 mm, the mold tube being placed opposite the mold tube with a groove constructed according to the invention without a groove. The stress reduction achieved with this technique in the mold tube preferably affects the service life and reduces the thermal conditional distortion of the mold tube. In this calculation, the mold tube according to the present invention has 8 grooves on each side wall at a distance of 5 mm with a length of 200 mm extending in the casting direction. The intermediate groove has a depth of 5 mm, whereas the outer groove has a depth of 4 mm with a width of 12 mm or 8 mm. No groove is disposed in the corner region of the side wall.

冷却溝の具体的実施例にとってその深さと幅に関して、冷却幾何学形状はそれにより形成された熱流に出来るだけ良く一致させて、それによってさらに均質な温度区域が達成され得て、それがこれまでは不十分にしか達成されないことが、重大である。冷却溝が熱提供が最高である側壁の中心に深く且つ幅広く又はそのいずれか一方に形成され、つまりｓ隅半径付近領域よりも大きな横断面を有することが重要である。   For a specific embodiment of the cooling groove, with respect to its depth and width, the cooling geometry is matched as closely as possible to the heat flow formed thereby, so that a more homogeneous temperature zone can be achieved, It is crucial that is only achieved poorly. It is important that the cooling groove be formed deep and / or broadly in the center of the side wall where heat delivery is highest, i.e. having a larger cross section than the region near the s corner radius.

特に半径隅領域から１０ｍｍから１５ｍｍまでの間隔には、側壁に冷却溝が設けられていなく、冷却をここで高めなく且つ金型の剛性を不必要に弱めない。冷却溝が３ｍｍ〜６ｍｍの深さを有するときに、最善の成果が達成され得る。この場合には、冷却溝最高深さと金型管内面の間の６ｍｍの残存壁厚さが下回らない。   Especially in the interval from 10 mm to 15 mm from the radius corner region, no cooling groove is provided on the side wall, so that the cooling is not increased here and the rigidity of the mold is not unnecessarily reduced. Best results can be achieved when the cooling groove has a depth of 3 mm to 6 mm. In this case, the remaining wall thickness of 6 mm between the maximum depth of the cooling groove and the inner surface of the mold tube does not fall below.

冷却溝の幅は特に５ｍｍ〜２０ｍｍの間で選択すべきである。   The width of the cooling groove should be chosen in particular between 5 mm and 20 mm.

冷却溝の数を金型管の異なるフォーマット／寸法に適合するために、形成された溝寸法にとって、金型管の１００ｍｍ側面当たり４〜１０個の冷却溝の数が好ましいものと解った。   In order to adapt the number of cooling grooves to the different formats / dimensions of the mold tube, 4-10 cooling grooves per 100 mm side of the mold tube were found to be preferred for the groove size formed.

流体力学的に１と４の間の冷却溝の幅／深さの比が特に有利なものとみなされる。それから偏差する関係は流れ関係に不利な影響を有し、それによって溶湯面範囲における金型管の冷却出力並びに剛性に不利な影響を有する。冷却溝は、そこで応力ピークを回避するために、溝壁に対して小さいトランスミッション半径を備えている。   Hydrodynamic groove width / depth ratios between 1 and 4 are considered particularly advantageous. Deviations from it have a detrimental effect on the flow relationship, and thereby have a detrimental effect on the cooling power and stiffness of the mold tube in the melt surface area. The cooling groove has a small transmission radius relative to the groove wall to avoid stress peaks there.

冷却溝は理想的には入口出口領域には冷却水の流れ最適化と圧力損失の減少に貢献する半径を有する。   The cooling groove ideally has a radius in the inlet / outlet region that contributes to cooling water flow optimization and reduced pressure loss.

冷却溝の有効と見なされた配列では、その対向する溝中心から測定された間隔が１０ｍｍと２５ｍｍの間にある。冷却溝の幅に対する溝中間間隔の１．２〜３の比は驚くべき良い成果を提供する。   In an arrangement deemed effective for the cooling groove, the distance measured from its opposite groove center is between 10 mm and 25 mm. A ratio of the groove intermediate spacing to the cooling groove width of 1.2-3 provides surprisingly good results.

基本的には、冷却溝の幅が側壁の中心に対してより大きくなっていて、さらに深さが中心に対して増加することを得ようと努められている。異なる冷却溝幾何学形状は金型管の機械加工によって或いは金型管の変形における切り屑なし加工によっても製造され得る。 Basically, it is sought to obtain that the width of the cooling groove is larger with respect to the center of the sidewall and that the depth further increases with respect to the center. Different cooling groove geometries can also be prepared by no machining chips in machining or by deformation of the mold tube mold tube.

冷却溝がメニスカス目標位置の上部のおよそ５０ｍｍで開始して、メニスカス目標位置の下およそ３００ｍｍまで延びている範囲に配置されているときに、有効である、というのは、この領域では最大熱流密度が生じ、それにより金型管の側壁における応力は最大であるからである。鋳造方向により深く位置する領域、即ちメニスカス目標位置の下部の３００ｍｍより大きい間隔の領域は確かに同様に冷却されなければならなく、無論、既に形成されたストランド殻に基づいて温度不均質性はこの発明による構成された溝が強制的にこの下領域に於いて必要であるより大きくない。この発明による構成された溝がメニスカス目標位置の上部のおよそ５０ｍｍで開始して、メニスカス目標位置の下およそ３００ｍｍまで延びているときに、卓越した成果が既に達成される。 It is effective when the cooling groove is arranged in a range starting about 50 mm above the meniscus target position and extending to about 300 mm below the meniscus target position, in this region the maximum heat flow density This is because the stress on the side wall of the mold tube is maximum. The region deeper in the casting direction, i.e. the region with a spacing of more than 300 mm below the meniscus target position, must certainly be cooled as well, and of course the temperature inhomogeneity is based on the already formed strand shell. The constructed groove according to the invention is not forced larger than necessary in this lower region. Excellent results are already achieved when the constructed groove according to the invention starts approximately 50 mm above the meniscus target position and extends to approximately 300 mm below the meniscus target position.

この発明は、次に図面に図示された実施例に基づいて詳細に説明される。図１ａと図１ｂは詳細に図示されていない形式で水槽に位置されている金型管１を一方では斜視図で示し且つ一方では斜視図の拡大で示す。この金型管１の特殊性は、金型管１の外面３に形成されている特殊に構成された冷却溝２である。この冷却溝２は金型管１の全長にわたり延びていなく、むしろ専ら金型管１の上鋳造側領域に存在する。この実施例では、冷却溝２は２００ｍの長さを有する。この冷却溝２はメニスカス目標位置の領域に存在し、この場合にはこれは図示された冷却溝２の上四分の一に位置する。この金型管１の冷却溝２における特殊性は、これら金属管がすべて同じ幅と深さではなく、むしろ幅と深さにおいて異なっていることである。この実施例では隅領域４に向いた外部冷却溝２ａと２ｂはそれぞれの側壁の中間領域に位置する冷却溝２ｃより狭い。 中間冷却溝２ｃが例えば１２ｍｍの幅を有する間に、四つの外部冷却溝２ａと２ｂは例えば８ｍｍの幅を有する。すべての冷却溝２ａ、２ｂ、２ｃは同じ長さを有する。けれども、それは冷却溝２ａ、２ｂ、２ｃの幅ばかりではなく、むしろその深さも同じである。それで、冷却溝２ａ、２ｂ、２ｃが入口出口領域において、即ちそれぞれに端面に 1つの半径５を有する。個々の冷却溝２ａ、２ｂ、２ｃの最高深さに対する半径２の移行が水平線によって認識される。中間冷却溝２ｃの場合には深さが最大に認識できる。外側に隣接した冷却溝２ｂの深さは多少より浅い。この深さは隅領域４に向いた外部冷却溝２ａでは最小である。   The invention will now be described in detail on the basis of an embodiment illustrated in the drawings. FIGS. 1a and 1b show, on the one hand, a perspective view and, on the other hand, an enlarged perspective view, of a mold tube 1 which is located in a water tank in a manner not shown in detail. The peculiarity of this mold tube 1 is a specially configured cooling groove 2 formed on the outer surface 3 of the mold tube 1. The cooling groove 2 does not extend over the entire length of the mold tube 1 but rather exists exclusively in the upper casting side region of the mold tube 1. In this embodiment, the cooling groove 2 has a length of 200 m. This cooling groove 2 exists in the region of the meniscus target position, which in this case is located in the upper quarter of the cooling groove 2 shown. The peculiarity of the mold tube 1 in the cooling groove 2 is that these metal tubes are not all the same width and depth, but rather differ in width and depth. In this embodiment, the external cooling grooves 2a and 2b facing the corner region 4 are narrower than the cooling groove 2c located in the intermediate region of each side wall. The four external cooling grooves 2a and 2b have a width of, for example, 8 mm, while the intermediate cooling groove 2c has a width of, for example, 12 mm. All the cooling grooves 2a, 2b, 2c have the same length. However, it is not only the width of the cooling grooves 2a, 2b, 2c, but rather the depth. Thus, the cooling grooves 2a, 2b, 2c have one radius 5 in the inlet / outlet region, i.e. each end face. The transition of radius 2 with respect to the maximum depth of the individual cooling grooves 2a, 2b, 2c is recognized by the horizontal line. In the case of the intermediate cooling groove 2c, the depth can be recognized to the maximum. The depth of the cooling groove 2b adjacent to the outside is somewhat shallower. This depth is minimal in the external cooling groove 2 a facing the corner region 4.

隅領域４は冷却溝を備えていない。金型管１は詳細に図示されていない水案内薄板により水槽内に固定オされているので、冷却水は個々の冷却通路２ａ、２ｂ、２ｃに押し込まれる。この水案内薄板は、金型管が水隙間内の中心に保持されているように配置されている。   The corner region 4 is not provided with a cooling groove. Since the mold tube 1 is fixed in the water tank by a water guide thin plate not shown in detail, the cooling water is pushed into the individual cooling passages 2a, 2b and 2c. The water guide thin plate is arranged so that the mold tube is held at the center in the water gap.
