金属の連続鋳造においては、従来装置によれば樹枝状組
織が同方向に成長して得られる柱状晶が。In continuous casting of metals, conventional equipment produces columnar crystals obtained by dendritic structures growing in the same direction.
鋳型側壁より鋳物中央方向に成長し、中央部に等軸晶が
成長する場合が多い。 また異物等が鋳物内部に蓄積さ
れ、内部欠陥が多く生じる。It grows from the side wall of the mold toward the center of the casting, and equiaxed crystals often grow in the center. Further, foreign matter and the like accumulate inside the casting, causing many internal defects.
このため塑性加工時に、柱状晶成長方向に圧縮された場
合に１合金によっては１粒界割れを生じ好ましくない。For this reason, during plastic working, when compressed in the direction of columnar crystal growth, some alloys may cause single grain boundary cracking, which is undesirable.
この欠点を解決するために、特公昭５５−４．６２６５
のように、鋳型を加熱し、鋳型出口部で凝固させる装置
が提案されているが、その運転においてブレークアウト
を起こし易く操業」二難点があった。 また鋳型自体を
加熱するためヒータを鋳型内に内蔵させるものであり、
好ましい構造ではなかった。In order to solve this drawback,
A device that heats the mold and solidifies it at the mold outlet has been proposed, but it has two drawbacks: breakouts are likely to occur during operation. Additionally, a heater is built into the mold to heat the mold itself.
It was not a desirable structure.
即ち機器内電線等細物の導電用材としてのロッド等を製
造する際に要求される材質の項目である１、異物、ピン
ホール等内部欠陥の少ないこと。In other words, the material requirements for manufacturing rods and the like as conductive materials for thin objects such as electric wires in equipment are as follows: 1. The material must have few internal defects such as foreign objects and pinholes.
２．長尺物で均一な品質をもつもので、偏析の少ないこ
と。2. It must be long and of uniform quality, with little segregation.
３、柱状晶が、ロンドの中心に向かって成長しないこと
。3. Columnar crystals should not grow toward the center of the rondo.
の条件を満たす製品を得ることが出来、さらに鋳造の際
に必要な項目である安全性を有することを満たす連続鋳
造装置が、要求されている。There is a need for a continuous casting apparatus that can obtain products that meet the following conditions, and that also has safety, which is a necessary item during casting.
本発明は、以」二の要望を満たすものである。The present invention satisfies the following two needs.
即ち、鋳型の一端は、溶融金属浴に突出し、他端は、冷
却構造体に接した構造である連続鋳造装置である。That is, it is a continuous casting apparatus in which one end of the mold protrudes into a molten metal bath and the other end is in contact with a cooling structure.
さらに、本発明の実施態様として、以下のものを提供す

鋳型の材料が、熱良導体の耐火物である上記鋳造装置。The casting apparatus described above, wherein the material of the mold is a refractory material that is a good thermal conductor.
鋳型の一端と他端の間に、保温用発熱体を設けた上記鋳
造装置。The casting apparatus described above includes a heat-retaining heating element provided between one end and the other end of the mold.
鋳型の冷却構造体の溶融金属浴側から、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された」二記
Ｕ造装置。2. U-building device having a structure in which inert gas and/or neutral gas is blown into the mold wall surface from the molten metal bath side of the mold cooling structure.
以ド本発明について、詳細に述へる。The present invention will now be described in detail.
本発明装置が適用される金属は、銅、金、銀、アルミニ
ウム、亜鉛、鉛、スス等およびこれらの合金等である。Metals to which the device of the present invention is applied include copper, gold, silver, aluminum, zinc, lead, soot, and alloys thereof.
特に熱良導体のものが好ましい。In particular, those with good thermal conductivity are preferred.
本発明の鋳型の一端は、溶融金属浴に突出している。
突出させることにより溶融金属の熱により鋳型を加熱す
るものである。 この事により別の加熱手段を用いずに
過剰加熱することなく溶湯の入口側で凝固面を保持でき
る。 また同時に、一方向凝固を可能とし、結晶粒の非
常に大きい鋳造組織を得ることができるものである。One end of the mold of the present invention projects into the molten metal bath.
By making the mold protrude, the mold is heated by the heat of the molten metal. This makes it possible to maintain a solidified surface on the inlet 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.
また同時に鋳型出口部で溶融金属は、全く存在しない。At the same time, no molten metal is present at the mold outlet.
これによりブレークアラ１へのない連続鋳造を可能と
するものである。This enables continuous casting without any breakage.
以−に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 continuous casting apparatus described above 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. It is preferable to form the mold so as to surround the entire periphery of the mold.
また、鋳型の冷却構造体の溶融金属浴側から、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。Further, the structure is such that inert gas and/or neutral gas is blown into the mold wall surface from the molten metal bath side of the mold cooling structure.
この構造とすることにより、凝固した金属の偏析を防
止し、溶融金属の温度を均一に保持するものであ、る。This structure prevents segregation of the solidified metal and maintains a uniform temperature of the molten metal.
上記ガスは、少なくとも溶融金属の鋳型への入口部の
溶体を攪拌混合する役割をなすものである。 冷却構造
体に接っした鋳型の部分より、少くとも鋳型の入口側か
ら、装入できる構造であることが好ましい。The gas serves at least to stir and mix the solution at the entrance of the molten metal to the mold. It is preferable that the structure 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.
さらに本発明に用いる鋳造装置は、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。Furthermore, the casting apparatus used in the present invention may be one in which a mold is provided at the lower part of a melting furnace or a holding furnace, or one in which a mold is provided on a side wall of a melting furnace or a holding furnace.

が好ましい一方向凝固を可能にするためである。41 Regarding the thickness of products suitable for use with the device of the present invention, products with a very large diameter are not suitable. For example, the diameter is 20m
The size is less than m. This is because the temperature of the mold is preferably within a range that can be transmitted to the molten metal or semi-solid metal in order to enable unidirectional solidification.
