本発明は、固体酸化物相の生成を阻止する耐火性材料か
らなるストラン１−″鋳込装置の浸漬流しに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a strand 1-'' caster immersion sink made of refractory material that prevents the formation of solid oxide phases.
鋼鉄のストランド鋳込では浸漬流し７を使用し、これは
主として１種又は数種の耐火性酸化物（Ａｌ１２０３、
Ｓ＋０２）、炭素（グラファイト）及び結合剤からなっ
ている。この浸漬流しでは、内壁にアルミナからなる付
着物が形成する。この付着物は浸漬流しの内径の減少を
生ぜしめ、これは流れの速度の減少をもたらす。更にこ
の刺着物から取りけずられたアルミナ切片は、異種物質
として鋳込鋼鉄で不利な影響を及ぼす。In steel strand casting, an immersion sink 7 is used, which is mainly made of one or more refractory oxides (Al1203,
S+02), carbon (graphite) and a binder. In this immersion sink, deposits of alumina form on the inner walls. This deposit causes a reduction in the inner diameter of the immersion sink, which results in a reduction in flow velocity. Furthermore, the alumina pieces removed from this impregnation have a detrimental effect on the cast steel as foreign material.
浸漬流しでアルミナ粒子の沈着を避けるためＫは、Ｃａ
又はＣａＳ ｉの合金を液体鋼鉄に添加することは公知
である（ドイツ公開特許第２７３１３６７号明細書）。To avoid alumina particle deposition in the immersion sink, K is replaced by Ca.
It is also known to add alloys of CaS i to liquid steel (DE 27 31 367).
このようにして、アルミニウムで処理する際に生じるＡ
Ｃ２０３粒子が変性される。即ち液体形（Ｃａ−アルミ
ネート）になる。In this way, the A produced when processing with aluminum
C203 particles are modified. That is, it becomes a liquid form (Ca-aluminate).
この操作法は必ずしも成果が得られない。また面倒で費
用がか〜る。結局、この方法はＡε２０６又はＳ ＋
０２からなる浸漬流しの場合には、内壁に、浸漬流しの
耐火性材料、アルミナ又は二酸化珪素及び液体鋼鉄の間
の反応によって生じる付着物又は生成物が形成する状態
に対しては解決を有しない。This method of operation does not always yield results. It is also troublesome and expensive. In the end, this method is suitable for Aε206 or S +
In the case of immersion sinks consisting of 02, there is no solution to the condition in which deposits or products are formed on the inner walls resulting from the reaction between the refractory material of the immersion sink, alumina or silicon dioxide, and liquid steel. .
本発明の課題は、固体酸化物相の生成を阻止するストラ
ンド鋳込装置の浸漬流しの提案である。The object of the invention is to propose an immersion sink for a strand casting device which prevents the formation of solid oxide phases.
この課題は、本発明によれば液体鋼鉄と接触する浸漬流
しの内部が酸化マグネシウムからなることによって解決
される。This object is solved according to the invention in that the interior of the immersion sink in contact with the liquid steel consists of magnesium oxide.
好ましくは浸漬流しの内部が、浸漬流しに常用の耐火性
酸化物、例えばＡｇ２Ｏ３又はＳ ｉ Ｏ７からなる層
によって取囲まれている。Preferably, the interior of the immersion sink is surrounded by a layer of refractory oxides customary for immersion sinks, such as Ag2O3 or SiO7.
更に本発明の構成によれば、内部とこれを取囲む層との
間に空気のスリットを備えていることが考慮される。Furthermore, according to an embodiment of the invention, provision is made for air slits to be provided between the interior and the layer surrounding it.
本発明によって得られる利点は、主として簡単な方法に
より不利な付着物が浸漬流しの内壁で阻止さね、これに
より前記欠点が生じな（・ことである。The advantage obtained by the invention is primarily that, in a simple manner, unfavorable deposits are prevented on the inner walls of the submersion sink, so that the aforementioned disadvantages do not arise.
次に添付図面につき本発明を説明する。The invention will now be described with reference to the accompanying drawings.
液体鋼鉄と接触する浸漬流し１の内部２ば、酸化マグネ
シウム（ＭｇＯ）からなっている。内部２を、公知耐火
性酸化物、例えばＡｌ！２０３．５ｉ０２又は他の適当
な耐火性月利からなる外部層３で被覆するのが有利なこ
とが立証された。これにより浸漬流し１は、あまり十分
ではないＭｇＯの機械的抵抗力にも拘らず十分な堅牢度
が得られる。The interior 2 of the submersion sink 1, which is in contact with the liquid steel, consists of magnesium oxide (MgO). The interior 2 is made of a known refractory oxide, such as Al! It has proven advantageous to coat with an outer layer 3 of 203.5i02 or other suitable refractory grade. This provides the immersion sink 1 with sufficient robustness despite the mechanical resistance of the MgO, which is not very sufficient.
内部２及び外部層３の膨張係数が著しく異なる場合には
、空気のスリット４が設けられている。Air slits 4 are provided if the expansion coefficients of the inner 2 and outer layers 3 are significantly different.
意外なことにも実験により、前記浸漬流しは内部２に付
着物を有せず、それ故−全不変の速度で鋳込むことがで
きることが判明した。Surprisingly, experiments have shown that the immersion sink has no deposits in the interior 2 and can therefore be cast at a completely constant rate.
