Abstract
Description
1) ACアーク炉でコークス及び電極を用いた還元、スラグ予熱ならびに沈降による方法。
2) 水平な円筒形の回転炉、例えばテニエンテ錬かん炉(Teniente-Schlackereinigungsofen)中で、還元剤の導入(Eindusung)による方法。
3) 垂直な転炉、例えばTBRC炉又はアイザスメルト炉、オアースメルト炉又は類似の方法での、還元剤の注入による方法。
−例えば、鉄合金法(例えばFeNi、FeMn、FeCr、FeNb及びTiO2製法)の場合のような金属滴、
−硫化物もしくは酸化物の形の金属(この場合は、アイザスメルト炉、オアースメルト炉、オートクンプ炉又はTBRC炉が一次溶解装置として機能する)、
−酸化物の供給材料の加工により、例えば電気炉又は直立炉から生成物として生じる金属及び合金
を含有する。
Fe3O4+CO=3FeO+CO2
Cu2O+CO=2Cu+CO2
CO2+C=2CO
酸化銅の還元は磁鉄鉱共還元によって制限される。この共還元の条件はこの反応の平衡によって次のように決定される:
(Cu2O)スラグ+3(FeO)スラグ<=>2(Cu)金属+(Fe3O4)スラグ
溶解方法及び得られたマット品質に応じて溶融スラグ中の銅含量は2〜10%であり、磁鉄鉱含量は10〜20%である。
γA=γ±j×B
式中: γA − 見かけ比重N/m3、
γ − 比重N/m3、
j − 液体中の電流密度A/m2、
B − 磁気誘導T。
カソード: Fe3++e=Fe2+
Cu++e=Cu0
アノード: SiO4 4−+2C=SiO2+2[CO]+4e
O2−+C=[CO]+2e
磁鉄鉱のカソード分解及び銅の析出は磁鉄鉱還元及び銅の除去の全体速度を高める。アノード生成物としてのCOの生成は磁鉄鉱還元の別の中心を成す。
FEMB=2πjBr3
式中: FEBM − 浮力N、
j − 電流密度A/m2、
B − 磁場のインダクタンスT、
r − 懸垂物の半径m。
ε − 表面電荷coul/m2、
E − 電場強度V/m、
ηs − スラグ粘度Pa s、
κ − スラグの導電率/Ω/m、
w − 金属/スラグ界面の抵抗Ωm2。
