鋳造することによっておこなわれていた。[Prior Art] Conventionally, continuous casting of copper and copper alloys uses a copper mold 1 equipped with a water-cooled jacket 1-2, as shown in FIG. This was done by injecting flux 10 from above and continuously casting while supplying flux 10 to the surface of the molten metal.

酸化を防止するとともに、潤滑材としての機能を果たす
ものとしてその使用は不可欠であった。In this case, the use of flux was indispensable as it not only keeps the surface of the molten metal in the mold warm and prevents oxidation, but also functions as a lubricant.

。[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention, in continuous casting of copper and copper alloy, applies lubricating oil to the inner wall surface of the mold, and then uses a heat insulating material provided above the mold. The molten metal is supplied to the enclosed sump, and is cooled from around the mold while preventing the molten metal from penetrating into the connection by a non-heat-resistant ring inserted in the molten metal side connection between the heat insulating material and the mold. , a method for drawing out the solidified ingot from the bottom of the mold, and a method in which a pool surrounded by a heat insulating material is provided above the mold, and a heat-resistant material ring is inserted between the heat insulating material and the mold on the molten metal side. That is.

された状態で鋳型内での凝固がおこなわれるから、酸化
物等の巻込みは起こらない。According to the present invention, a molten metal is provided above the mold and surrounded by a heat insulating material, and the molten metal filled in the molten metal pool solidifies in the mold while being isolated from the atmosphere. Such entanglement will not occur.
また、潤滑油の消費も極めて少なく、鋳造開始前に潤滑
油を鋳型内面に塗布しておけば、それ以上の潤滑油の補
充は不要となる。Furthermore, the consumption of lubricating oil is extremely low, and if lubricating oil is applied to the inner surface of the mold before starting casting, no further replenishment of lubricating oil is required.

滑性を支えるためのフラックス使用は必要でなくなる。Therefore, the use of flux to support oxidation prevention and lubricity, which are important in the prior art, is no longer necessary.
以下、図示の実施例に基づいて本発明の詳細な説明する
。Hereinafter, the present invention will be described in detail based on illustrated embodiments.
第１図は本発明による連続鋳造装置の１実施例を示した
断面図であり、前記した従来例を示す第３図と同一構成
部位には同一の参照符号を付しである。FIG. 1 is a sectional view showing one embodiment of a continuous casting apparatus according to the present invention, and the same reference numerals are given to the same components as in FIG. 3 showing the conventional example described above.

どの悪影響を与°える。In FIG. 1, 1 is a copper mold equipped with a water cooling jacket 2, and above the mold 1 is provided a sump 3 surrounded by a heat insulating material 4. Molten metal 6 of copper or copper alloy is supplied from the upper part of the trough 3 via a float 9 from a gutter 8. The molten metal 6 is filled into the sump 3 and starts to solidify in the mold, but the molten metal temperature during casting of copper and copper alloys is, for example, 950 to 950°C.
Since it is as high as 1150°C and has high permeability, it easily penetrates into the gap between the mold 1 and the heat insulating material 4. When molten metal enters the gap,
It causes adverse effects such as solidification and horizontal cracks on the ingot surface.
このため本発明においては、断熱材４と鋳型１との溶湯
側接続部に耐熱材リング５を介挿させることが重要な要
件となる。Therefore, in the present invention, it is an important requirement to insert the heat-resistant material ring 5 into the molten metal side connecting portion between the heat insulating material 4 and the mold 1.

Ceramics such as N are used effectively. The shape of the heat-resistant material ring 5 is circular, square, or similar to the horizontal cross-sectional shape of the mold, and the cross-section is preferably wedge-shaped as shown in FIGS. 2(a) and 2(b).

しに鋳造をおこなうことができ、フラックスの使用は不
要となる。Before starting casting, a lubricant such as graphite or silicone oil is applied to the inner wall surface of the copper mold 1. Since the solidification of the molten metal 6 in the mold 1 is performed in a position isolated from the atmosphere by the molten metal filled in the sump 3, there is no entrainment of oxides and the consumption of lubricating oil is extremely low. Therefore, as described above, if a lubricant is applied to the inner wall surface of the mold before the start of casting, casting can be carried out without any further supply of lubricant, and the use of flux becomes unnecessary.
