The present invention relates to a nozzle module comprising: a nozzle partially put in a container where molten steel is received; and a protection member installed to surround the outer surface of the nozzle. The protection member is installed in a section corresponding to flux positioned on the surface of the molten steel. According to embodiments of the present invention, the protection member is installed on the outer surface of the nozzle to prevent the outer surface of the nozzle from being directly in contact with the flux in casting. Accordingly, the protection member protects the nozzle from the flux to prevent the melting of the nozzle. Thus, the present invention prevents the nozzle from being damaged or cut to enable casting for a long time and to stabilize the casting work; thereby increasing productivity. Also, the present invention can increase the quality of the slab by reducing the number of changing the stage of the nozzle. [Reference numerals] (AA) Flux; (BB) Molten steel |
