Title: SEALING METHOD, SEALING DEVICE, AND CONTINUOUS CASTING APPARATUS PROVIDED WITH THE SEALING DEVICE
Abstract:
A sealing device (50) for sealing a gap (81) between a pair of casting rollers (11a, 11b) and a casting chamber (20, 20B). The casting chamber (20, 20B) is provided below the pair of casting rollers (11a, 11b) and is provided with an upper opening (21a) allowing passage of a sheet (2) emerging from the pair of casting rollers (11a, 11b). The sealing device (50) is provided with an inert gas nozzle (54a, 54b) for spraying an inert gas at respective perimeter surfaces (11aa, 11ba) of the pair of casting rollers (11a, 11b). The sealing device (50) achieves a simpler and more efficient seal of the gap (81) between the pair of casting rollers (11a, 11b) and the casting chamber (20, 20B) below the rollers.
