湯量をイ′冴度よぐルIJ御することか困難であった。In a metal melting furnace such as a crucible-type induction furnace 2, as shown in FIG. 1, the furnace %1 is tilted by a hydraulic cylinder 2 about a shaft 3 to a position indicated by a ``shu'' to tap the metal. In the Gindoro, the relationship between the Sugome Sakukuri Zenkakuashi and the Ryo Takui in the entry process is the second one.
The temperature changes as shown by curve B in Figure 7, and for this reason, it is difficult to control the amount of hot water dispensed to a precise degree.

ことができる。Above theory 1. In accordance with the present invention, the 14'↓ side angle of the furnace body is used as a guideline to calculate the angular velocity around 1 of the furnace body for quantitative tapping using a predetermined calculation formula. Now that we have a means of checking and a means of controlling the discharge to perform feedback control so that the angular velocity of the furnace is equal to the angular velocity calculated above, it is possible to perform quantitative dispensing. , it is possible to control the tilting of the furnace body at the same time.
