に関する。Regarding.
以下本発明について、詳細に述べる。The present invention will be described in detail below.
本発明が適用される銅は、無酸素銅、高純度銅である。Copper to which the present invention is applied is oxygen-free copper and high-purity copper.
本発明の方法において、鋳型の一端は、溶融銅浴に突出

の非常に大きい鋳造組織を得ることができるものである
。In the method of the invention, one end of the mold projects into a molten copper bath. By making it protrude, the mold is heated by the heat on the melting side. This makes it possible to maintain the solidified surface on the artificial side of the molten metal without using a separate heating means or overheating. At the same time, it enables unidirectional solidification and allows a cast structure with very large crystal grains to be obtained.
さらに鋳型の他端は、冷却構造体に接した構造である。Furthermore, the other end of the mold is in contact with the cooling structure.
鋳型の一方を加熱し他端を冷却することにより一方向凝
固を好ましく行い得るものである。One-way solidification can be preferably performed by heating one end of the mold and cooling the other end.
また同時に、Ｕ型出口部で溶融側は、全く存在しない。At the same time, there is no melting side at all at the U-shaped outlet.
これによりブレークアウトのない連続鋳造を可能とする
ものである。This enables continuous casting without breakouts.
以上の連続鋳造装置をより好ましくするためには、鋳型
の材料としては、熱良導体の耐火物を用いることが好ま
しい。例えば、窒化珪素、炭化珪素、黒鉛等である。In order to make the above continuous casting apparatus more preferable, it is preferable to use a refractory material with good thermal conductivity as the material for the mold. For example, silicon nitride, silicon carbide, graphite, etc.
さらに鋳型の一端と他端の間に、鋳型の温度が、外気に
左右されることのないよう保温用発熱体を設けることが
好ましい、鋳型の全周を囲むように形成することが好ま
しい。Furthermore, it is preferable to provide a heat-retaining heating element between one end and the other end of the mold so that the temperature of the mold is not influenced by the outside air, and preferably to surround the entire circumference of the mold.
また、鋳型の冷却構造体の溶融銅浴側から、鋳型壁面に
不活性ガス及び又は中性ガスを吹き込む構造とする。こ

造体に接した鋳型の部分より、少なくとも鋳型の入口側
から、装入できろ構造であることが好ましい。Further, the structure is such that inert gas and/or neutral gas is blown into the mold wall surface from the molten copper bath side of the mold cooling structure. This structure prevents the segregation of impurities in the solidified ingot and maintains a uniform temperature on the melting side. The above-mentioned gas plays the role of stirring and mixing at least the melt at the entrance to the mold on the melting side. It is preferable to have a structure that allows charging from at least the inlet side of the mold, rather than the part of the mold that is in contact with the cooling structure.
さらに、本発明方法に用いるＵ造装置は、溶解炉、又は
保持炉の下部に鋳型を設けたもの、あるいは、溶解炉、
又は保持炉の側壁様に鋳型を設けたものであっても良い
