The present invention relates to a nozzle, comprising: a nozzle body including an inner hole part in which molten steel is able to be moved; and a discharge port through which the molten steel is able to be moved to the outside. In regards to this, the discharge port comprises: an upper side and a lower side spaced from each other and aligned with each other; and a pair of lateral sides which connect both end parts of the upper side and the lower side respectively, wherein a distance between the upper side and the lower side is longer than the lengths of the upper side and the lower side. In addition, clogging of the nozzle may be inhibited or prevented by controlling a flow speed or a speed rate of the molten steel discharged to the discharge port by modifying a shape of the discharge port to which the molten steel is discharged. |
