Claims (1)
して構成された高炉出銑口であつて、炉壁煉瓦表
面に接して構築されたガスシール層と：軸央部に
溶銑滓流出口を形成すると共に前記ガスシール層
を被覆して構築された高耐蝕性で、かつ前記ガス
シール層より低強度の不定形耐火物層とからなる
２層構造としたことを特徴とする高炉出銑口。 A blast furnace taphole is constructed by surrounding a refractory with a metal frame protruding from the furnace shell, and has a gas seal layer built in contact with the surface of the furnace wall bricks: hot metal at the center of the shaft. It is characterized by having a two-layer structure consisting of a slag outlet and a monolithic refractory layer that is highly corrosion resistant and has a lower strength than the gas seal layer, which is constructed by covering the gas seal layer. Blast furnace taphole.
