In addition to stably producing high-quality ingots, the aim is to save energy, reduce costs, and improve workability.

ようにしたものである。On the other hand, in order to manufacture high-quality copper or copper alloy materials, continuous casting is carried out using a heated mold casting machine that heats a mold above the melting point of the cast metal and casts the ingot by directing cooling water to the ingot. This method prevents solid phase formation and growth from the mold and makes the surface of the ingot the final solidified part, so it is possible to obtain an ingot with a unidirectionally solidified composition that has excellent internal and surface quality. As shown in Fig. 5, the heating mold continuous casting machine heats the mold (1) using a heating element to a temperature higher than the melting point of the cast metal, and then inserts the ingot (3b) into the mold (1).
) The molten metal (3a) in the mold (1) is cooled and solidified by the cooling device (4) set near the outlet of the mold, and the ingot (3b) is continuously pulled out by the pinch rolls (5). This is what I did.

を生ずる欠点がある。(Problems to be solved by the invention) In the hot mold casting method, when the phase changes from liquid to solid at the solidification interface, a void is created between the ingot and the mold due to volumetric contraction and thermal contraction accompanying solidification. The presence of molten metal in this area is important for improving the quality of the ingot, and by acting as a lubricant, an ingot with a glossy and defect-free surface can be obtained.However, Figure 6 (
As shown in b), the solidified tip (A>) on the surface of the ingot (3b)
The length of the distance (X) between the inlet tip (B) and the molten metal penetration tip (B) is important for improving the quality of the ingot, and the ideal state is X=O. By the way, as the hydrostatic pressure of the molten metal 1 (3a) increases, X increases and the molten metal (3a) comes into contact with the cooled ingot (3b) and the heated mold (1). As shown in Figure 6 (c), an ingot (3b) with a changed plate thickness, or a thin solidified shell due to in-phase growth from the surface of the ingot (3b) as shown in Figure 6 (c) breaks due to friction with the mold. crack (6)
There is a drawback that it causes
このため鋳塊引き出し方向が上方引き上げ、水平引き上
げにおいても静水圧、即ち湯面の高さを一定もしくはほ
とんど零にする必要がある。For this reason, it is necessary to keep the hydrostatic pressure, that is, the height of the molten metal level, constant or almost zero even when the ingot is pulled upward and horizontally.

は高価なものとなる。In addition, the heating mold casting method can produce ingots of excellent quality, but since casting is performed only by cooling the ingot without cooling the mold, it is less expensive than the casting method using a normal cooling mold. The disadvantage is that productivity is low. Furthermore, when continuous casting is performed using heated molds using commonly used gas-heated or electrically heated melting furnaces, holding furnaces, casting furnaces, etc., equipment costs and holding power are relatively high compared to production volume. Moreover, the amount of hot metal discharged from the melting furnace is either an overflow type or a furnace head method, and in this case, the amount of hot metal temporarily increases when raw materials are charged in the former case, and when the furnace is tilted in the latter case. In order to reduce equipment costs, it is conceivable to place a casting furnace with a heated mold after the melting furnace, but in this case, the molten metal level in the casting furnace will fluctuate significantly, so it is necessary to install a holding furnace after the melting furnace. , the molten metal must be supplied to the casting furnace using a nozzle stopper, etc., and the equipment cost is high.
