    摘要: A twin roll-type sheet continuous casting apparatus includes a nozzle for supplying molten metal; a pair of casting rolls for casting the molten metal supplied from the nozzle into a sheet, the casting rolls being horizontally disposed in parallel relation to each other, being cooled, and rotated in opposite directions, respectively; a coiler; and a support sheet extending generally horizontally below the pair of casting rolls for receiving the cast sheet and transferring it to the coiler, and being taken up by the coiler along with the cast sheet placed therein. Since tension is not applied to the cast sheet, even a brittle material can be continuously cast into a sheet. Also, a dummy sheet requested for starting the casting of the sheet becomes unnecessary, and even when a rupture of the sheet occurs, the apparatus can be continuously operated without stopping the operation.
