Abstract
【解決手段】溶鋼の流量制御に使用するスライディングノズル用のSNプレート10のSNプレート本体1は、ピッチ、タール若しくはフェノール樹脂またはこれらの溶剤成分の単独若しくは混合物からなる揮発分を0.1質量%以上含有する耐火物からなる。このSNプレート10の非摺動面である背面側4に、非通気性の金属製皮膜または無機質材料の1若しくは複数の層からなる非通気性の皮膜6を設ける。さらに、この皮膜6の外側に、SNプレート10の背面側4に加えられる面圧を分散させるためのシート材として、セラミックシート7とブリキ板8を積層する。
【選択図】図1
Description

2 内孔
3 SNプレートの摺動面
4 SNプレートの背面側
5 ダボ部
6 非通気性の皮膜
7 セラミックシート
8 ブリキ板
9 金属バンド
