Abstract

　内孔側に高耐食性、高い付着防止性等の高機能の耐火物層を配置して耐用性を高めた連続鋳造用ノズルにおいて、その内孔側層と本体材質である外周側層との熱膨脹差に起因する外周側層の押し割れを防止すると共に、鋳造途中の内孔側層の剥落を防止することができる連続鋳造用ノズル及び製造方法を提供する。 　内孔側層２と中間層４の境界部分、及び中間層４と外周側層３の境界部分が直接接触し一体化した構造を持ち、中間層とこの中間層に隣接した内孔側層及び外周側層との１０００°C非酸化雰囲気中における接着強度が０．０１ＭＰａ以上１．５ＭＰａ以下であり、かつ、２．５ＭＰａの加圧下、１０００°C非酸化雰囲気における中間層の可縮率Ｋ（％）が１０％以上８０％以下の連続鋳造用ノズルである。
