はひしゃく音用いる。In the casting process of magnesium alloy, after dropping #l into the base metal, magnesium chloride, potassium chloride, barium chloride, etc. The sludge that remains in the bath water is removed to form a layer of sludge, but the sludge that still remains in the bath water is allowed to settle in the bath water and then sent to the bottom of the crucible at the SK sedimentation site. The settling time varies depending on the amount of melting, but is about 10 to 50 minutes. After settling, this melt 1k is poured into a mold, etc. To draw out the f# hot water, a ladle is used for die casting, and a ladling sound is used for hand mixing.

Mix in the #@ that was pumped out. As mentioned above, the sludge contains the aforementioned potassium chloride, barium chloride, and other chlorides, and if they are mixed into the bath water, the quality of the cast iron will be significantly reduced. The author achieved 111kPs during this time by sinking it near the bottom of a partition device with a Sosoku structure.

−Ａ、第１図−Ｂ参照）。The partitioning device 1 used in the method of the present invention, as shown in FIG. The material used for the equipment is stainless steel SUS 430, etc., which does not generate oxide scale even at high temperatures of about 700°C and does not contain nickel, which affects the corrosion resistance of the magnesium base metal. For example, it is created by bathing. The size of the partition iron [1 is different depending on the size of the crucible 6 used for dissolving magnesium, and the dimensions of each part are based on the following standards (see Figure 1-A and Figure 1-B).

When the injected metal has completely submerged and the hot water reaches a temperature of 680 to 700°C, a flux is added to refine the bath water. The amount of flux used varies depending on the cleanliness of the bullion used, and is 1 to 5 times the amount of metal used.

A large amount of sludge is generated by this scrubbing and adheres to the walls of the crucible or accumulates on the bottom of the crucible. This sludge is removed by Tsukuki, but K in the molten metal is removed.
Due to floating sludge and flux, approximately 1

力１られる。Pump out the molten metal using a . Although this molten metal is disturbed, due to the presence of the partition plate 5 of the partition device 1, the molten metal containing sludge is not affected by the disturbance force S and remains precipitated. For this reason, the molten metal that is pumped out is not contaminated with sludge or flux, resulting in a reliable casting product that does not suffer from corrosion resistance or damage.
