ナ−黒鉛質耐火物が使用されている。[Detailed Description of the Invention] [Field of Industrial Application] In continuous casting, molten steel is passed from a ladle to a tundish or from a tundish to a mold through a nozzle (long nozzle, tundish nozzle, or immersion nozzle).
The nozzle is designed to be transferred sequentially, and an alumina-graphite refractory is used for this nozzle.
このアルミナ−黒鉛質耐火物は耐食性、耐スポーリング

遂には閉塞してしまうといった事態を生じさせる。Although this alumina-graphite refractory has excellent corrosion resistance and spalling resistance, it has the disadvantage that nozzle clogging is likely to occur due to adhesion of alumina precipitated from molten steel. Especially in the case of aluminum killed steel, A is a deoxidation product in molten steel.
Nonmetallic inclusions such as jlgOs are present, and these substances adhere to the inner hole wall or discharge port of the nozzle, gradually grow, and eventually become clogged.
また、溶鋼中の上記非金属介在物のクラスター或いは閉
塞物が鋳型品中に捕捉されると、製品の欠陥となる。Furthermore, if clusters or blockages of the non-metallic inclusions in the molten steel are captured in the molded product, it will result in defects in the product.

た閉塞防止効果が得られない。In order to solve these drawbacks, a method is known in which inert gas is blown into the inner circumferential surface of the nozzle to prevent non-metallic inclusions such as Al t Os from adhering. When continuous casting is repeated, the non-metallic inclusions may grow inside the nozzle discharge port and cause blockage, making it impossible to obtain a stable blockage prevention effect.

It is also known to adsorb and filter deoxidized products by arranging a filter made of Os-based material or CaO-based material, but if the filter becomes clogged with deoxidized products, However, replacing filters was time consuming and hindered operations.
この発明は、上記従来の事情に鑑みて提案されたもので
あって、ノズル本体のアルミナ−黒鉛質の特性を活かし

着しない連続鋳造用ノズルを提供することを目的とする
ものである。This invention has been proposed in view of the above-mentioned conventional circumstances, and is a continuous casting method that takes advantage of the alumina-graphite properties of the nozzle body and prevents non-metallic inclusions from adhering to the nozzle inner hole wall or discharge port. The purpose is to provide a nozzle for
上記目的を達成するために、この発明は以下のような手

び／或いは吐出口に、ＣａＯを５０〜１００重量％を含
有する石灰質材で所定厚さのコーティング層を形成した
ものである。In order to achieve the above object, the present invention employs the following means. That is, a coating layer of a predetermined thickness is formed on the nozzle inner hole wall and/or the discharge port of the nozzle body using a calcareous material containing 50 to 100% by weight of CaO.
これにより、石灰質材コーティング層のＣａＯと溶鋼中

A composition with a low melting point and a low specific gravity such as It does not mix.
コーティング層は、溶損によって徐々に薄くなるが、無
くなってしまったときにはノズル交換をすればよい。The coating layer gradually becomes thinner due to erosion, but when it disappears, the nozzle can be replaced.
上記石灰質材としては、ライムタリンカー、ドロマイト
クリンカ−、マグネシアライムクリンカー等が用いられ
、その組成は、ＣａＯを５０〜１００重量％を含有して
いるのが好ましく、５０重量％以下では上記効果が低下
する。As the above-mentioned calcareous material, lime talinker, dolomite clinker, magnesia lime clinker, etc. are used, and the composition thereof preferably contains 50 to 100% by weight of CaO, and if it is less than 50% by weight, the above effects are not achieved. descend.
コーティング層の厚さは、ノズル本体の寿命に対応する
厚さ、即ち５〜Ｌｏｗが好ましく、５鶴以下では溶損が
早くなり、ノズル本体の寿命が残っている間にノズル交
換をしなければならず、逆にｌＯ鶴以上であると、ノズ
ル本体の寿命が尽きてもコーティング層だけが残ること
になり、不経済である。The thickness of the coating layer is preferably a thickness that corresponds to the lifespan of the nozzle body, that is, 5~Low.If it is less than 5cm, it will melt quickly and the nozzle must be replaced while the lifespan of the nozzle body remains. On the other hand, if it is more than 1O, only the coating layer will remain even after the life of the nozzle body ends, which is uneconomical.
上記コーティング層は、ノズル本体を形成するとき同時

成してもよい。The coating layer may be integrally molded at the same time as forming the nozzle body, or the nozzle body and the coating layer may be molded separately, and the coating layer may be fitted into the nozzle body later. After molding the nozzle body, the coating layer may be formed by a method such as casting.

化性、耐溶鋼性が低下する。The nozzle body is made of a refractory containing 10 to 50% by weight of graphite, as in the past, and examples of refractory raw materials other than graphite include alumina, silica, zirconia, silicon carbide, zircon, and silicon. If graphite is less than 10% by weight, thermal shock resistance will be poor, and if it exceeds 50% by weight, oxidation resistance and molten steel resistance will be reduced.

い。In addition, Example 1. As shown in FIG. 1(a), a coating layer 2 was formed on the entire discharge port 3 and inner hole wall 4 of the nozzle body 1, but as shown in FIG.
A coating layer 2 may be formed on the lower half of the inner hole wall 4.
