The present invention relates to molds for continuous casting of high melting point and active metals such as metals.

行われている。In the case of this kind of high-melting-point, active metal, continuous casting is carried out in some cases using water-cooled copper molds, just as in the case of steel. However, unlike steel, this continuous casting is performed under a vacuum or inert gas atmosphere because the metal has a high melting point and is active, and unlike continuous steel casting, lubricants such as flux are used. Then, since the molten metal reacts with the flux, it is not used, and since the molten metal may also react with the inner wall surface of the water-cooled copper mold, the cooling capacity of the water-cooled copper mold is increased.

The bottom metal 30 is set on the inner bottom of the water-cooled copper mold 2.

て鋳造が行われる。Next, the molten raw material supply device 25 is operated to supply the molten raw material onto the bottom metal 30 set in the inner bottom of the water-cooled copper mold 21, while the plasma heating device is operated and the plasma torch 23 melts the raw material. After that, an initial solidified shell is formed on the bottom metal 30 by cooling from the upper surface of the bottom metal 30 and the inner wall surface 31 of the water-cooled copper mold 21, and when a molten metal pool 32 is formed, the solidified portion on the bottom metal 30 is The ingots 33 are successively drawn downward by the ingot drawing device 28 and continuously cast. During continuous casting, the upper end outer peripheral part 34 of the molten metal pool 32 formed in the water-cooled copper mold 21 is solidified before it comes into contact with the inner wall surface 31 of the water-cooled copper mold 21, and the upper end outer peripheral part 34 of the molten metal pool 32 is solidified before it contacts the inner wall surface 31 of the water-cooled copper mold 21. Alternatively, casting is performed in such a way that reaction and burning between the molten metal in the molten metal pool 32 and the inner wall surface 31 do not occur.

冷銅鋳型２１の寿命が短くなる等の問題が起こる。[Problems to be Solved by the Invention] By the way, when the water-cooled copper mold 21 is used as described above, reaction and burning occur between the outer peripheral portion 34 of one end of the molten metal pool 32 or the molten metal of the molten metal pool 32 and the inner wall surface 3. Although casting is carried out in such a way as to prevent the melt from melting, the adjustment is extremely difficult. For example, the surface of the molten metal in the molten metal pool 32 is constantly disturbed by the influence of the plasma torch 23 for melting and heat retention. The contact state between the upper end outer circumferential portion 34 of the molten metal pool 32 and the inner wall surface 31 of the water-cooled copper mold 21 is not stable, and the surface of the cast ingot 33 has wrinkles, double skin, etc., and is extremely uneven and voided. It has become unhealthy with many. Furthermore, if the molten metal in the molten metal pool 32 overflows from the molten metal pool 32 and comes into direct contact with the inner wall surface 31 of the water-cooled copper mold 21 for a long time, the inner wall surface 31 of the water-cooled copper mold 21 may react with the molten metal and contaminate the molten metal, or Problems arise such as the inner wall surface 31 of the water-cooled copper mold 21 being damaged by melting and the life of the water-cooled copper mold 21 being shortened.
