While performing vacuum treatment under Hg conditions, continuous vacuum defoaming casting was carried out into the master mold through the transport pipe at a discharge rate of 3 J/1 lin using a squeeze pump, and sampling was performed from time to time, and the air content was determined from the ground weight filled to 21 cups. It was measured. In addition, the strength of the predetermined prey was also measured by sampling in the same manner. Furthermore, as a comparative example, the kneaded material 311 was prepared at an effective volume of 30. &
The change in air content over time was measured only when the kneaded material was treated using a vacuum omnimixer r 0M-30AV J (manufactured by Chiyoda Giken Industries). The results were as shown in Table 1.

Even after 20 to 30 minutes of treatment, the air was not removed sufficiently and sufficient physical property values were not obtained.
, 3 is continuous vacuum defoaming casting, and it is recognized that defoaming was almost done from the start of casting, and that reliably improved physical properties were obtained. In addition, beautiful casting surfaces were observed for the samples produced by No. 1 and No. 003 even without using a vibrator. The reason why the air content was large after 10 minutes in Experiments No. 1 and No. 3 was because the filling state in the flexible hose was released in the final state.

Measured according to IS R5201. The size of the specimen is 4
X 4 X 16C111. Furthermore, in the case where the air content shows a negative value, it is thought that the specific gravity of the kneaded product increased due to evaporation of the kneading water under vacuum, resulting in a negative value.

The tip of the kneaded material is opened near the rotating shaft, and the kneaded material is supplied from the outside onto the jinka.The kneaded material supplied onto the 0-rotation jinkasa is made into a thin film, slides on the surface plate, and is released onto the tank wall by centrifugal force. The gas is then allowed to fall naturally along the tank wall, during which time it is sufficiently degassed.

ズポンプに排出する。The degassed thin layer of the kneaded material is stirred by a stirring blade (27), sent to a squeeze pump through an extrusion screw (28) and a transport pipe, and poured into a master mold. The stirring blade (27) is used to prevent the fluidity of the kneaded material from decreasing, and the extrusion screw (28) forcibly discharges the kneaded material to the squeeze pump.

しスクリューなどの強制排出Ｒ構が設けられている。Other examples of the forced discharge mechanism include a propeller type forced discharge mechanism, a rotary set forced discharge mechanism, and a piston type forced discharge mechanism. If the fluidity of the kneaded material is low, the kneaded material is likely to accumulate in the vacuum chamber, and even if the rotational force of the squeeze pump is increased, it will not be possible to obtain an appropriate casting speed, so it is necessary to control the casting speed. In order to increase the casting speed, a forced discharge R mechanism such as an extrusion screw is provided.

The physical properties of the samples produced in Examples and Comparative Examples were certainly improved compared to those with a high air content, and beautiful casting surfaces were observed even without using a vibrator. Note that the reason why the air content was large at the end of each of the Examples and Comparative Examples was because the filling state in the flexible hose was released at mf&.
