Abstract (en)

[origin: EP3326733A1] [Problem] The purpose of the present invention is to provide a cast-iron casting, a method for manufacturing a cast-iron casting, and equipment for manufacturing a cast-iron casting, which are capable of performing a plating treatment or an enameling treatment without defects on a surface of the cast-iron casting, regardless of the specifications of the cast-iron casting, without decreasing productivity or increasing manufacturing costs. [Elected Drawing] Fig. 4 [Solution] In the method for manufacturing a cast-iron casting, a mold is molded by decompressing molding sand, and a melt is poured into the mold. The inside of the mold is decompressed until the temperature of a casting formed by the melt falls to or below an A1 transformation point. The equipment for manufacturing a cast-iron casting comprises: at least one mold; a frame feed device that moves the mold; at least one fixed suction device that decompresses the inside of the mold when the mold is stopped; at least one movable suction device that moves while decompressing the inside of the mold instead of the fixed suction device when the mold is moving; and a temperature sensor that measures the product surface temperature of the casting.
