UP-DRAWING CONTINUOUS CASTING APPARATUS AND UP-DRAWING CONTINUOUS CASTING METHOD

摘要

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.

主权项

1. An up-drawing continuous casting apparatus comprising:
a holding furnace that holds molten metal; a shape determining member that is arranged above a molten metal surface of the molten metal held in the 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 when the solidification interface determined by the image analyzing portion is not within a predetermined reference range.
