る。2. Description of the Related Art Conventionally, in a foundry, the work of pouring molten metal into a mold frame has been done by skilled workers who have long experience. That is, the molten metal was loaded from a melting furnace into a trolley with a sprue having a generally cylindrical upper end and was conveyed to a position where a pouring section or a mold frame is arranged. Since the trolley is usually supported by the suspending means, it is necessary for an operator to rotate and tilt the trolley and inject the molten metal into the gate of the mold frame.
At this time, the hot water gate and the mold frame hot water gate are provided at a distance from each other, and this distance fluctuates with the tilt rotation of the hot spring. Further, the surface area of the molten metal in the ladle fluctuates with the inclination of the ladle, and when the ladle is tilted at a constant speed, the amount of molten metal gradually varies. Therefore, in order to correct the variation in the distance from the hot pot and the variation in the pouring amount, the operator must simultaneously perform the work of adjusting the positional relationship of the hot bath with respect to the mold frame hot spring and the work of adjusting the tilt rotation angle of the hot pot. , You have to do it while observing the hot water flow curve.
As described above, these operations are extremely difficult and require a high level of technology, and at the same time, extremely dangerous.

As shown in Fig. 2, a pouring method using a tribe in which the vertical cross-sectional shape through the pouring spout 2 is fan-shaped so that the surface area (S = S 1 + S 2 ) of the molten metal in the ladle 1a during pouring is approximately constant Proposed. In the fan-shaped tribe pouring method, the positions of the molten metal drop start point of the pouring spout 2 and the mold frame spout 100c are always kept constant regardless of the rotation angle of the tribe 1a, that is,
It has the feature that l and h (FIG. 6) do not change and that the pouring streamline T of the molten metal between the ladle 1a and the mold frame spout 100c does not change.

かくせざるを得ないといつた欠点があつた。However, such a fan-shaped ladle 1a has a higher manufacturing cost than the conventional cylindrical ladle, and its use in a foundry of a certain scale in terms of running cost. Limited. In addition, the exposed surface area of the molten metal in the fan-shaped ladle is large, and the amount of radiant heat from the surface area is almost twice that of the conventional ladle with a circular cross section, which leads to a decrease in the molten metal temperature and a short pouring time. There were some drawbacks if I had to do this.
