Summary:PROBLEM TO BE SOLVED: To provide a dipped nozzle for continuous casting, which needs no gas flow to molten steel and can prevent the blockage of a nozzle sufficiently without causing the erosion of the nozzle.SOLUTION: A dipped nozzle for continuous casting, in which an inner hole body made of a non-carbon material is arranged partially or wholly of a nozzle inner wall to contact with molten steel. The dipped nozzle is characterized in that a non-carbon material uses an alkali aqueous solution of silicic acid as a binder.SELECTED DRAWING: Figure 1 【課題】本発明の目的は、溶鋼へのガス吹きが不要で、ノズルの溶損を発生させることなく、ノズルの閉塞を十分に防止できる連続鋳造用浸漬ノズルを提供することにある。【解決手段】本発明の鋼の連続鋳造用浸漬ノズルは、溶鋼と接するノズル内壁の一部または全部にノンカーボン材から構成される内孔体を配置してなる鋼の連続鋳造用浸漬ノズルにおいて、ノンカーボン材がバインダーとして珪酸アルカリ水溶液を用いるものであることを特徴とする。【選択図】図１
