- 液状の銑鉄(2)又は液状の鋼(3)とスラグ成分(4)をベースとして高マンガン低炭素鋼(1)を製造するための方法において、
約6%Cの液状のフェロマンガン(5)と約0.1%Cの液状の鋼(3;3a)と必要量のスラグ成分(4)をFeMn精錬転炉(6a)に投入することによりプロセスが開始され、トップランス(8)と下吹きノズル(9)からの酸素(7)の組合せの吹込みにより炭素成分が約0.7〜0.8%に低減され、その後、予備溶湯から成る低温の最終製品の一部が冷却剤(10)として投入され、その後、下吹きノズル(9)から酸素(7)を連続的に吹き込むことにより炭素成分が約0.05〜0.1%Cにまで低減されることを特徴とする方法。 - トップランス(8)もしくは下吹きノズル(9)からの酸素(7)と酸素・不活性ガス混合物(11)の組合せの吹込みにより、分圧が低減されることを特徴とする請求項1に記載の方法。
- プロセスの全てのステップが1630〜1650°Cの温度範囲内で実施されることを特徴とする請求項1又は2に記載の方法。
- 取鍋炉(12)内での分析の調整をするため、SiMn及び/又はFeAlが溶湯(13)内に投入されることを特徴とする請求項1〜3のいずれか1つに記載の方法。
- FeMn精錬転炉(6a)に、鋼1トン当たり約380kgの量の6%Cの液状のFeMn75カーバイドと530kgの量の0.1%Cの液状の鋼と必要量のスラグ成分(4)が投入され、これにより、溶湯(13)には、C=2.6%の炭素含有量に相当する23.3kgの炭素が含まれ、炭素含有量が、少なくとも1つのトップランス(8)と複数の下吹きノズル(9)からの酸素の組合せの吹込みにより約C=0.7%に低減され、引き続き約150kgの予備溶湯から成る低温の最終製品が冷却剤(10)として投入され、下吹きノズル(9)からの酸素・不活性ガス混合物(11)により、炭素含有量が約C=0.1%に低減されることを特徴とする請求項1〜4のいずれか1つに記載の方法。
- 銑鉄又は炭素鋼の供給(14)とスラグ成分(4)及び不純物元素(15)の添加により、高マンガン低炭素鋼(1)を製造するための溶解装置において、
材料の流れにおいて、一方で還元炉(16)又は銑鉄(2)のための高炉(17)が、他方で炭素鋼(3a)のための製鋼転炉(6)又は電気アーク炉(18)が、FeMn精錬転炉(6a)の前に設けられており、プロセス手順において、FeMn精錬転炉に取鍋炉(12)が接続していることを特徴とする溶解装置。
