【産業上の利用分野】この発明は、アルミニウム又はア
ルミニウム合金の連続鋳造機に備えられたスパウト（湯
口）の構造に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a spout (gate) provided in a continuous casting machine for aluminum or aluminum alloy.
【０００２】[0002]
【従来の技術】所謂プロペルチ法は、外周にＵ字形溝を

いる。2. Description of the Related Art In the so-called Properci method, a steel belt is brought into contact with the surface of a ring mold (casting foil) having a U-shaped groove on its outer periphery, and molten metal is injected from a spout between the U-shaped groove and the steel belt. To solidify.

【発明の課題】ところが、スパウトからリングモールド
の溝に溶湯を注入する間に、溶湯の表面に酸化膜が形成
され、これが鋳塊に混入して圧延後の線材に疵が生じる
原因となっている。However, an oxide film is formed on the surface of the molten metal during pouring the molten metal from the spout into the groove of the ring mold, which causes the oxide film to mix with the ingot and cause flaws in the wire rod after rolling. There is.
【０００４】そこで、この発明の課題は、前記酸化膜の
生成をできるだけ防止し、かつ酸化膜が生じても鋳塊に
混入するのを阻止することである。Therefore, an object of the present invention is to prevent the formation of the oxide film as much as possible and prevent the oxide film from being mixed into the ingot.

【課題の解決手段】上記の課題を解決するため、この発
明においては、樋状スパウトの先端部に、スパウトの上
面開放部を覆いかつ溶湯に接触する柔軟な耐熱性カバー
を取り付けたのである。In order to solve the above problems, in the present invention, a flexible heat-resistant cover is attached to the tip of the gutter-shaped spout so as to cover the open upper surface of the spout and come into contact with the molten metal.
【０００６】[0006]
【作用】耐熱性カバーがスパウトの先端部上面を覆って
いるため、溶湯の空気との接触が遮断され、酸化膜が形
成され難い。Since the heat resistant cover covers the upper surface of the tip of the spout, the contact of the molten metal with the air is blocked, and it is difficult to form an oxide film.
【０００７】また、酸化膜が形成されても、溶湯に接触
しているカバーにかき戻されて鋳塊に混入しない。Further, even if an oxide film is formed, it is scraped back by the cover that is in contact with the molten metal and does not mix into the ingot.

The tip 10 of the spout 4 enters between and
Is to be injected. A cover 20 is attached to the tip portion 10 of the spout 4.

2 is formed of, for example, a ceramic fiber or a carbon sheet, and its tip slightly presses the upper surface of the molten metal A as shown in FIG. The pressing force is, for example, 0.1 to 3 g / mm 2 . In order to adjust this pressing force, a weight 23 made of a similar material may be provided at the tip of the tongue member 22.

ることができ、品質向上に資するところ大である。As described above, according to the present invention, since the flexible heat-resistant cover that covers the upper surface of the spout and has its tip in contact with the molten metal is provided, it is possible to prevent the molten metal from being oxidized, and to oxidize it. Even if a film is formed, it can be scraped off at the tip of the cover, so that it is possible to prevent oxides from being mixed into the ingot, which is a great contribution to quality improvement.
