Abstract
Continuous strip casting device comprises a pair of parallel casting rolls onto which molten metal is supplied by metal supply means. Casting rolls are enclosed by a casting chamber into which hot strip is delivered downwardly from the casting rolls. Strip passes downwardly into a cooling chamber where it can either fall into a moveable scrap box at the bottom of chamber or be guided by operation of moveable apron through an exit door from chamber into a heat exchange chamber provided with heaters. A pair of seal rolls are moveable in a seal chamber to form a seal between chambers and are provided with respective gas inlets to admit oxidation inhibiting gas into those chambers. Scrap box is moveable into and out of the bottom of chamber via a scrap box exchange chamber fitted with an airtight door.
