化せしめるものであった。(Prior Art) Conventionally, a gravity casting method has been used to cast grid substrates for lead-acid batteries. In this gravity casting method, as shown in Fig. 1, a heat insulating material 2 is applied to the inner surface of a mold 1 to prevent uneven cooling of the molten lead alloy 3 poured into the mold, and to solidify the casting grid as much as possible. It is intended to make the crystal structure uniform. However, it is difficult to uniformly apply the heat insulating material, and the cooling rate differs depending on the location in the mold due to differences in the amount of molten metal depending on the location of the casting grid, and as a result, the solidification structure of the casting grid is non-uniform. Not only is it
Since the cooling rate is slow, a large crystal structure of several hundred microns or more is formed. When a battery is assembled using a cast lattice substrate with such large crystal grains, corrosion preferentially progresses along the grain boundaries of the lattice substrate during practical use, causing it to lose its function as a conductor at an early stage. This shortened the lifespan of the battery.

イ内の空気を巻きこんで０．５〜１＋ｏ＋程度のボイド

った。Furthermore, the cast lattice found by the gravity casting method contains voids of approximately 0.5 to 1+o+ due to the air inside the casting cavity, and local corrosion rapidly progresses from the vicinity of these voids, causing the lattice to be used as a lattice substrate at an early stage. This was to reduce the functionality of the system.

However, since the lattice substrate is obtained by filling the cavity in an extremely short period of time, the solidified crystal structure of the lattice substrate is fine and homogeneous. Moreover, since no air is involved, no voids are generated, and it is not possible to use conventional gravity. The service life of the electrode plate can be improved by at least 60% compared to a lattice substrate made by the casting method, and the sensor detects the molten metal rising inside the molten metal delivery nozzle by reducing the vacuum level, so the pressure is reduced. It is always constant, the equipment is simple, the workability is automated, and it is extremely useful in industries such as cranes.
