本発明は、とくにスラブ鋼材を製造する場合に、攪拌用
コイルを使用することによ、り三相交流電磁場を連続鋳
造装置のサポート・ローラ列の弊道内に発生させる電磁
攪拌装置に関する。[Detailed Description of the Invention] The present invention generates a three-phase alternating current electromagnetic field within the support roller row of a continuous casting machine by using a stirring coil, especially when manufacturing slab steel materials. It relates to an electromagnetic stirring device.
金属溶湯の成分を動かすため、接置しつつあるスラブ用
連続鋳造材の中で溶融部分を動かすための、攪拌用コイ
ルよりなる三相交流電磁場発生器は、通常コンパクトな
態様で形成されている（西ドイツ特許出願公開第２５５
９５１１号）。Three-phase alternating current electromagnetic field generators consisting of stirring coils for moving the components of the molten metal in the continuous casting slab that is being placed are usually constructed in a compact manner. (West German Patent Application Publication No. 255
No. 9511).
この態様においては、電磁場の３つの極が直方体の構成
要素として設けられている（西ドイツ特許出願公開第２
４０１１４５号の第２３図と第２４図参照）。In this embodiment, the three poles of the electromagnetic field are provided as elements of a rectangular parallelepiped (West German Patent Application No. 2
(See Figures 23 and 24 of No. 401145).
この構成要素の寸法を例示すると次の通りである。Examples of dimensions of this component are as follows.
すなわち長さ約８００ ｍｍ、幅約３００＋＋ｍ１高さ
約４００ｍｍであり、そしてその長軸が連続鋳造材の移
送方向に平行に配置されている。That is, it has a length of about 800 mm, a width of about 300++ m, and a height of about 400 mm, and its long axis is arranged parallel to the direction of conveyance of the continuous casting material.
三相交流磁極をこのようにコンパクトな要領で配置する
ことは、西ドイツ特許出願公開第２５５９５１１号の第
３図に示されている。The arrangement of three-phase alternating current magnetic poles in such a compact manner is illustrated in FIG. 3 of DE-A-2559511.
しかしこのような装置をスラブ用の連続鋳造設備に組み
込むと、ローラによる連続鋳造材の支えが比較的長い距
離にわたってとぎれることとなる。However, when such a device is incorporated into continuous slab casting equipment, the support of the continuous casting material by the rollers is interrupted over a relatively long distance.
この装置の長軸の長さが３００ｍｍとするとスラブを支
えない最小長さは例えば５００ｍｍとなる。If the length of the long axis of this device is 300 mm, the minimum length without supporting the slab is, for example, 500 mm.
したがって支えが十分でないためスラブが脹らんでそれ
に亀裂が生じるおそれがある。There is therefore a risk that the slab will swell and crack due to insufficient support.
そのほか脹らんだスラブは、装置本体に沿ってすべりな
がら動くため、装置本体に損傷を与える危険がある。In addition, the swollen slab slides along the device body, posing the risk of damaging the device body.
接置しつつあるスラブの金属溶湯成分に与える作用につ
いては、他にも欠点が存在している。There are other drawbacks with regard to the effect on the molten metal composition of the slab being placed.
それは、２本のサポート・ローラの間に設置される従来
一般に使用されている攪拌用コイルの配置では、比較的
短いスラブ長にしか攪拌作用が及ばないことである。The problem is that the conventionally commonly used stirring coil arrangement, which is installed between two support rollers, can only effect stirring over a relatively short slab length.
そのほかに、三相交流電流相Ｒ８Ｔの極が空間的に分離
され、それが連続鋳造材の引出し運動に対して直角方向
に配置されている攪拌コイル装置も提案されている（西
ドイツ実用新案第６９３０２１３号）。In addition, a stirring coil device has also been proposed in which the poles of the three-phase alternating current phase R8T are spatially separated and are arranged perpendicularly to the withdrawal movement of the continuous casting material (West German Utility Model No. 6930213). issue).
対象がスラブ材の場合にはこの種の装置は２本のサポー
ト・ローラの間に組み込まれるので、コンパクト型三相
交流電磁場発生器の配設の場合と同じ問題が生じる（西
ドイツ特許出願公開第２５５７５１１号参照）。In the case of slabs, devices of this type are installed between two support rollers, and the same problems arise as in the case of the arrangement of compact three-phase alternating current electromagnetic field generators (see German patent application no. (See No. 2557511).
公知のようにサポート・ローラの間隔は、金型からの距
離が大きくなればなるほど大きくなる。As is known, the distance between the support rollers increases as the distance from the mold increases.
これは、芯がいぜんとして液状であるスラブ材の徐々に
大きくなる静力学的な圧力を支えるためには、金型から
の距離に従がってローラの直径を大きくする必要がある
からである。This is because the diameter of the roller needs to increase with distance from the mold in order to support the gradually increasing static pressure of the slab material whose core is still liquid. .
スラブ用設備におけるサポート・ローラ列の代車発明の
目的は、三相交流電磁場を発生させるためにサポート・

鋳造材を引出す方向においてスラブ用連続鋳造材を支え

分で攪拌作用を確保することが可能な装置を提供するこ
とである。The purpose of the invention is to provide support rollers in slab equipment to generate a three-phase alternating current electromagnetic field.
An electromagnetic stirring device installed in the area of the rollers, which makes it possible to support the continuous casting material for slabs in the direction of pulling out the continuous casting material, and to ensure the stirring action in a larger part of the slab than before. The purpose is to provide equipment.
上記の目的は、本発明に係る特許請求の範囲第１項の特
徴項に記載された特徴により達成される。The above object is achieved by the features set out in the characterizing claims of claim 1 of the present invention.
本発明の対象のその他の構成態様は、特許請求の範囲の
実施態様項の記載より明らかである。Other embodiments of the object of the invention are apparent from the description of the embodiment section of the claims.
本発明装置を連続鋳造材の支持装置と組み合わせて使用
すれば、スラブの脹れを避けることができるとともに、
接置しつつあるスラブ用連続鋳造材の内の液状部分に対
して比較的広い範囲にわたり攪拌作用を与えることがで
きる。If the device of the present invention is used in combination with a support device for continuous cast materials, slab swelling can be avoided and
It is possible to apply a stirring action over a relatively wide range to the liquid portion of the continuous cast material for slabs that is being placed in contact.
すなわち、普通の攪拌コイルならば少くとも２個使用し
なければならなかった程度のスラブの部分に対して、攪
拌作用を与えることができる。That is, it is possible to provide stirring action to a portion of the slab that would require the use of at least two ordinary stirring coils.
