通路（１８） （１９）で夫々連通させである。When casting a product using a casting machine, for example, a die casting machine, as shown in Fig. 3, molten metal is transferred from a melting furnace (1) that centrally melts metal to die casting machines (2) of multiple casting lines installed in parallel. ) installed near the hand furnace (3
), and then, as shown in Figure 4, the molten metal (4) from the hand furnace (3) is poured into the ladle (5) of the automatic water heater.
) is pumped out and poured into the injection port (7) of the plunger (6) of the die-casting machine (2), and the plunger (6) presses the molten metal (4) into the molds (8) and (9). There is. The above-mentioned conventional hand furnace (3) has a furnace body (10) with an open top surface.
and a furnace lid (12) equipped with heating means (11) such as a heater.
), and the temperature of the molten metal (4) in the furnace body (10) is maintained constant by electrically controlling ON/OFF the heating means (11). The furnace body (19) of the hand furnace (3) is divided into a distribution chamber (15), a heating chamber (16) and a pumping chamber (17) by partition walls (13) and (14) made of heat insulating material. Hot water chamber (15), heating chamber (16), and heating chamber (16)
and the pumping chamber (17) are communicated with each other through passages (18) and (19) at the bottom of the partition walls (13) and (14), respectively.

を生じていた。By the way, since the temperature of the molten metal supplied to the die casting machine (2) has a great influence on the quality of the product, it is desirable that the temperature of the molten metal in the hand furnace (3) is constant. However, the degree of temperature drop during distribution due to the distance between the melting furnace (1) and each hand furnace (3), or the difference in the products produced by each die-casting machine (2) makes it difficult to determine the appropriate molten metal. Due to temperature differences, molten metal at the appropriate temperature is not necessarily delivered to the hand furnace (3), and therefore,
The temperature of the molten metal in the hand furnace (3) varied as shown in FIG.
そこで、従来、上記手許炉（３）の溶湯の温度バラツキ

A molten metal temperature adjustment furnace (20) is installed near the molten metal temperature adjustment furnace (20), and the molten metal distributed from the melting furnace (1) is placed in the molten metal temperature adjustment furnace (20).
) to adjust the temperature to the desired molten metal temperature, and then supplied to the hand furnace (3). The molten metal temperature adjustment furnace (20) is equipped with heating means such as a heater, and the temperature of the t8 molten metal is adjusted by electrically controlling ON/OFF the heating means.

の有効利用を図ることができないという問題があった。According to the conventional technology, in order to supply temperature-controlled molten metal to the die casting machine (2), a hand furnace (
It was necessary to install two furnaces: 3) and a molten metal temperature adjustment furnace (20). Therefore, each of the above units (3) (
20) is damaged by erosion by molten metal, the two furnaces (3) and (20) must be repaired, which requires a lot of effort and effort, which makes the workability worse, and makes it difficult to repair. The cost is high. Moreover, the number of man-hours required for cleaning the inside of the furnace increases, and the power consumption of the heater of the heating means increases, which is uneconomical. Furthermore, since two furnaces must be installed, a large installation space is required, and there is a problem in that the space cannot be used effectively.
