TWIN-ROLL THIN SHEET CONTINUOUS CASTING METHOD AND APPARATUS THEREFOR.

摘要

A twin-roll thin sheet continuous casting apparatus which comprises: a nozzle (14) for supplying molten metal; a pair of casting rolls (11, 12) for casting the molten metal supplied via the nozzle (14) into a thin sheet, disposed in parallel to each other and horizontally, cooled and rotated in directions opposite to each other; a coiler (17) and a supporting sheet (16) extended substantially horizontally under the pair of casting rolls and taken up by the coiler. Because no tensile force is applied to the cast thin sheet, not only a ductile material but also a brittle material can be continuously cast into a thin sheet. Further, a dummy sheet required when thin sheet casting is started can be dispensed with, and, even when breakage of a thin sheet occurs, the continuous operation can be executed without stopping the operation of the apparatus.
