Abstract: A pulling-up-type continuous casting apparatus includes a holding furnace that holds molten metal, a shape defining member disposed above a surface of the molten metal held in the holding furnace, and configured to define a cross-sectional shape of a cast-metal article as the molten metal passes through it, an image pickup unit that takes an image of the molten metal that has passed through the shape defining member, an image analysis unit that detects a fluctuation on the molten metal from the image and determines a solidification interface based on presence/absence of the fluctuation, and a casting control unit that changes a casting condition only when the solidification interface determined by the image analysis unit is not within a predetermined reference range. The casting control unit uses a reference range which differs according to the pulling-up angle of the molten metal.

Abstract: A pulling-up-type continuous casting apparatus according to an aspect of the present invention includes a holding furnace that holds molten metal, and a shape defining member disposed above a molten-metal surface of the molten metal held in the holding furnace, the shape defining member being configured to define a cross-sectional shape of a cast-metal article to be cast as molten metal passes through an opening formed in the shape defining member.

(where, 0°???90°) between an up-drawing direction of molten metal and an upper surface of a shape determining member is reduced to a first angle, drawing up the molten metal while maintaining the angle (?) at the first angle, and casting a first casting, and casting a connecting portion adjacent to the cast first casting; interrupting the drawing up of the molten metal, and dipping the connecting portion into the molten metal while passing the connecting portion through the shape determining member, and melting the connecting portion; and setting the angle (?) to a second angle that is larger than the first angle, restarting the drawing up of the molten metal and casting a second casting adjacent to the first casting.

Abstract: A method for processing a metal-cast article according to an aspect of the present invention includes a correcting step of starting to pressurize the metal-cast article by a press machine (10, 20) before a temperature of the metal-cast article 40 decreases to 200° C. or lower after casting is finished. Distortion can be accurately removed in a correction of a metal-cast article. Further, since there is no need to heat the metal-cast article again for the correction, the productivity and energy efficiency can be improved.
