The present invention introduces a ladle unit, comprising: a base ladle in which a space is arranged; and a replacement ladle arranged inside the base ladle to be detachable and formed in a shape corresponding to the base ladle such that an outer periphery contacts with an inner periphery of the base ladle, and in which a refractory is constructed. Accordingly, the ladle unit may improve production efficiency by rapidly replacing a ladle whose refractory should be repaired with a ladle in which a refractory is already constructed. |
