Description
− 鉄表面の酸化前の還元雰囲気は、合金化元素の外部酸化の危険を高める。これは、特に酸化が750℃のような高温で起こるときに当てはまる。なぜならマンガンのような元素は、600℃を越えると有意に酸化を開始するからである。
− 酸化領域、即ち第二領域は、特定のケーシングを全く持たない炉の内側に位置される。それは、酸化室が耐えなければならない高温、並びに様々な領域に分離するために使用されることができる最終的な装置のために多くの技術的な問題を生じる。さらに、酸化区域が主要な炉の内側にあるとき、表面を見ることができないのでシートの酸化状態を制御することは極めて難しい。それゆえ、測定システムは、設置されることができない。
− 第一区域における露点が、制御され、−50〜−15℃、好ましくは−30〜−15℃の範囲である。;
− ストリップが、第一区域において600〜750℃、好ましくは650〜750℃、より好ましくは650〜700℃に加熱される;
− CO+CO2の濃度が、第一区域で制御され、2体積%未満に維持される;
− 第二区域において、酸化剤媒体と不活性ガスの混合物が注入され、前記酸化剤媒体が、酸素であり、混合物中の酸素の濃度が、0.1〜5体積%、好ましくは0.5〜2体積%である;
− 混合物が、ストリップの各側について50〜300Nm3/hの範囲の流量で注入される;
− 第二区域において、ストリップの温度が、500〜700℃に維持される;
− 第二区域におけるストリップの滞留時間が、1〜10秒である;
− 第三区域において、ストリップが、750〜870℃の温度まで加熱される;
− 第三区域において、H2の濃度が3〜30体積%、好ましくは5〜20体積%に調整される;
− 第三区域において、露点が−50〜−5℃、好ましくは−20〜−10℃に制御される。

Claims (9)
- 封止手段によって分離された、第一区域(2)、第二区域(3)、及び第三区域(4)を連続的に含む炉(1)を通って走行する鋼ストリップ(5)上の表面反応を制御するための方法であって、第二区域(3)及び第三区域(4)における雰囲気が、それぞれ酸化及び還元するものであり、第一区域(2)において、鋼ストリップ(5)が600〜750℃に加熱され、雰囲気が以下の条件を有し、わずかに酸化するものである、方法:
− 2%未満のH2含有量、
− 0.1%未満のO2含有量、
− 0.03%より高い、H 2 OもしくはCO2、又はH2O+CO2の含有量、
− −50〜−15℃の範囲の制御された露点、
− 2%未満に維持されたCO+CO2の制御された濃度、但し、上記の全ての百分率は、体積で表示される。 - 第一区域(2)における露点が、−30〜−15℃の範囲である、請求項1に記載の方法。
- ストリップ(5)が、第一区域(2)において650〜750℃に加熱される、請求項1又は2に記載の方法。
- 第二区域(3)において、酸素と窒素の混合物が、ストリップ(5)の各側上で注入され、混合物中の酸素の濃度が、0.1〜5体積%である、請求項1〜3のいずれかに記載の方法。
- 第二区域(3)において、ストリップ(5)の温度が、500〜700℃に維持される、請求項1〜4のいずれかに記載の方法。
- 第二区域(3)におけるストリップ(5)の滞留時間が、1〜10秒である、請求項1〜5のいずれかに記載の方法。
- 第三区域(4)において、ストリップ(5)が、750〜870℃の温度まで加熱される、請求項1〜6のいずれかに記載の方法。
- 第三区域(4)において、H2の濃度が、3〜30体積%に調整される、請求項1〜7のいずれかに記載の方法。
