<p>Provided is a nozzle assembly for injecting molten steel capable of preventing molten steel from coagulating by minimizing the discharge of molten steel heat using a nozzle support with increased insulation and heat preservation. The nozzle assembly for injecting molten steel comprises an upper nozzle having a passage through which molten steel flows; a lower nozzle which is arranged on a lower part of the upper nozzle and has an injection hole on a lower end thereof to inject the molten steel; and a nozzle support which fixes the lower nozzle to a tundish and is made of ceramic.</p> |
