CONVEX-CAMBERED CONTINUOUS CASTING CRYSTALLIZER NARROW-FACE COPPER PLATE AND METHOD FOR USING SAME

WIPO Patent Application WO/2024/087976

A1

A convex-cambered continuous casting crystallizer narrow-face copper plate (100), comprising a first working face (1) and second working faces. Two second working faces are provided; the first working face is separately connected to the second working faces, first connecting lines (L1) are provided at the joints of the first working face and the second working faces, and two first connecting lines are provided; the cross section of the first working face is a convex arc, the first working face extends from the upper edge of the narrow-face copper plate to the lower edge of the narrow-face copper plate, and the height by which the first working face protrudes relative to the plane where the two first connecting lines are located gradually decreases in a direction from the upper edge of the narrow-face copper plate to the lower edge of the narrow-face copper plate. Also provided is a method for using the convex-cambered continuous casting crystallizer narrow-face copper plate. The width of the first working face is large enough, and the change amount of protrusion of the first working face is small, thereby reducing the probability of forming a remarkable width sideline crack defect and a remarkable double-strand shape defect in a continuous casting slab rolling process.
