A side sealing device for a twin-roll continuous casting apparatus, which supplies molten metal to a molten metal pool portion formed by a pair of rotating mold rolls and a pair of side weirs through an immersion nozzle and causes solidified shells to be formed and to grow on peripheral surfaces of the mold rolls to manufacture a cast strip, seals end surface sides of the mold rolls by each side weir. The side sealing device includes a side weir pressing unit that presses the side weir against end surfaces of the mold rolls, and a side weir lifter that pulls the side weir at least upward in a vertical direction.

A method of manufacturing an aluminum alloy wire includes: forming a rough drawing wire composed of an aluminum alloy containing aluminum, an additive element, and unavoidable impurities, the additive element including Si and Mg; obtaining an aluminum alloy wire by performing a treatment on the rough drawing wire, wherein the treatment includes at least one or more wire drawing treatments; forming a first solution treatment material by forming a solid solution of the aluminum and the additive element and then performing a quenching treatment on the solid solution, wherein the first solution treatment is performed directly before the last of the one or more wire drawing treatments is performed; a second solution treatment that forms a second solution treatment material by forming a solid solution of the aluminum and the additive element and then performing a quenching treatment on the solid solution.
