Abstract: An up-drawing continuous casting apparatus according to one aspect of the invention includes a molten metal holding furnace that holds molten metal; a shape determining member that is arranged near a molten metal surface of the molten metal held in the molten metal holding furnace, and that determines a sectional shape of a cast casting by the molten metal passing through the shape determining member, the shape determining member including a pattern provided on an upper surface of the shape determining member; an imaging portion configured to capture an image of the pattern that is reflected onto both retained molten metal that has passed through the shape determining member, and the casting formed by the retained molten metal solidifying; an image analyzing portion configured to determine a solidification interface from the image; and a casting controlling portion configured to change a casting condition.

Abstract: A pulling-up-type continuous casting apparatus according to the present invention includes a molten-metal holding furnace (101) that holds molten metal (M1), a starter (ST) that draws the molten metal (M1) held in the molten-metal holding furnace (101) from a molten-metal surface of the molten metal (M1), and a shape defining member (102) that defines a cross-sectional shape of a cast-metal article (M3) to be cast by applying an external force to the held molten metal (M2) drawn by the starter (ST), in which the starter (ST) includes a body part (107) and a tip part (108), the tip part (108) including a tip (109) having a horizontal cross section smaller than that of the body part (107).

Abstract: A pulling-up-type continuous casting method according to an aspect of the present disclosure is a pulling-up-type continuous casing method for pulling up molten metal held in a holding furnace by using a starter. When the starter is accelerated to a predetermined pulling-up speed at a start of casting, the pulling-up-type continuous casting method includes a first acceleration section in which the starter is accelerated from a standstill state to a first speed at a first acceleration, a second acceleration section in which the starter is accelerated from the first speed to a second speed at a second acceleration, and a constant speed section in which the starter is pulled up at the first speed, the constant speed section being positioned between the first and second acceleration sections.

Abstract: An up-drawing continuous casting method according to one aspect of the invention is an up-drawing continuous casting method for forming a bent shape in a cast casting by forming the casting in a first direction and then changing an up-drawing direction to a second direction and forming the casting in the second direction. This up-drawing continuous casting method includes drawing up the molten metal in the first direction; and changing the up-drawing direction to a third direction in which an angle between the third direction and the first direction is greater than an angle between the second direction and the first direction, from after a portion that will have the bent shape passes through the molten metal passage portion until the portion that will have the bent shape reaches a solidification interface, and then drawing up the molten metal.

Abstract: Provided is a connection terminal that maintains an approximately circular shape before or after a cylindrical part is fixed by resistance welding. The connection terminal used for a connection jig interconnecting target points includes a small-diameter conductive part and a large-diameter cylindrical part disposed to surround the small-diameter conductive part. The small-diameter conductive part has a front end protruding from a front end of the large-diameter cylindrical part. A part of the small-diameter conductive part is joined to a part of the large-diameter cylindrical part. A cutout part is formed in a part of a strip portion around an axis of the cylindrical part that at least includes the portion of the large-diameter cylindrical part which is joined to the small-diameter conductive part.
