PURPOSE: A sealing device is provided which is improved to block inflow of atmospheric air that is sucked into the molten steel through a bonding area between a collector nozzle and a long nozzle in the process of injecting molten steel of a ladle into a tundish, thereby deteriorates quality of steel ingot. CONSTITUTION: The device for sealing a nozzle in continuous casting using an aluminum sealing material is characterized in that a sealing material(211) made of aluminum is interposed between a collector nozzle(2) and a long nozzle for discharging and injecting molten steel in a ladle of the continuous casting process into a tundish, and a plural longitudinal holes(212) corresponding to the lower shape of the collector nozzle(2) are formed at appropriate positions of the aluminum sealing material(211).
