Hoisting type continuous casting device, hoisting type continuous casting method, and solid interface detection device

摘要

A hoisting type continuous casting device according to one embodiment of the present invention is provided with: a holding furnace (101) that holds a melt; a first shape regulating member (102) that is disposed in proximity to a molten surface of a melt (M1) that has been held in the holding furnace (101) and that regulates a cross-sectional shape of a casting (M3) by the melt being passed through; an imaging unit (109) that forms an image of a melt (M2) that has passed through the first shape regulating member (102); an image analyzing unit (110) that detects swinging motion in the melt from the image and determines a solid interface surface on the basis of the presence or absence of the swinging motion; and a casting control unit (111) that changes the casting conditions when the solid interface determined by the image analyzing unit (110) is not within a predetermined standard range.
