- 金属の連続鋳造プロセスのスプレーチャンバ内でストランドにスプレーされた冷却媒体の特性を正確にサンプリングする方法であって、
冷却媒体のサンプルを分離装置に通過させるステップであって、前記分離装置が、角度付きの流れ面を備え、当該流れ面が、前記冷却媒体のサンプルが前記流れ面上を流れ、前記冷却媒体のサンプルからの流体及び微粒子が前記流れ面を通過してモニタに達するように構成及び配置され、前記媒体中の大きい粒子は通過せずに前記角度付き流れ面を滑り落ちて除去され、これにより、前記面上での詰りの形成を防止し、前記角度付き流れ面が上部及び底部をそれぞれ有する複数の延在部材を含み、前記延在部材は、前記上部がより幅広で前記底部がより幅狭の先細状の構造を有し、且つ、隣り合う延在部材の上部が複数の細孔を画成している、ステップと、
前記分離装置から得られる前記流体及び微粒子をモニタリングし、前記冷却媒体の化学的又は物理的特性を決定するステップと、を含む、方法。 - 前記角度付きの流れ面が水平軸に対して20度〜60度の範囲の角度で配置され、且つ、サンプルが前記細孔プレートを10リットル/分〜100リットル/分の流量で通過することを可能にしている、請求項1に記載の方法。
- 前記分離装置が、前記ストランドのすぐ下に、又は、装置の腐食し易い特定の部品の下に配置される、請求項1に記載の方法。
- 前記複数の細孔が、0.15mm〜1mmの断面径を有する、請求項1に記載の方法。
- 前記分離装置が、0.1m2〜1m2の表面積を有する面を有する、請求項1に記載の方法。
- 前記サンプルが、以前に前記スプレーチャンバ内では蒸気であった凝縮液媒体、直接スプレー水、及びスプラッシュにより構成された混合液を含む、請求項1に記載の方法。
- 前記モニタが、pH測定器、フッ化物測定プローブ、酸化還元電位測定器、腐食測定器、温度、導電率、及び、これらの任意の組合せから成るリストから選択される装置である、請求項1に記載の方法。
- 前記サンプルが前記分離装置を通過していない場合、前記モニタへの流体流が、前記媒体中に存在する粒子により詰まっていると考えられる、請求項1に記載の方法。
- 前記モニタが、前記スプレーチャンバ内で生じている腐食の程度を判断する、請求項1に記載の方法。
- 前記モニタが、前記冷却媒体の組成が予め決められた量を超える腐食を生じさせるかどうかを判断する請求項1に記載の方法。
- 前記モニタにより測定された特性に応答して、前記媒体のpHを上下させ、且つ、適切な量の腐食抑制物質を投与するステップをさらに含む、請求項1に記載の方法。
- 前記サンプルが、モニタにより分析された後にスケールピットに送られるか、又は前記スプレーチャンバ内に戻される、請求項1に記載の方法。
- 前記モニタ内の前記微粒子は、それらが前記冷却媒体に導入されてから5分以内に前記モニタに到着した粒子である、請求項1に記載の方法。
