Decopperization in Steel Melt with Wire-feeding
-
摘要: 提出了用喂絲法向鋼液中插入銨鹽或氨基化合物的脫銅方法.在常壓下,Ar氣氛中,向鋼液中分別加入NH4Cl和NH2CONK2把約300g鋼水含銅量從0.6%降至0.47%~0.5%,僅用脫銅劑2~4g.氯化銨有氯化和銨分解的雙重脫銅作用,比尿素脫銅效果更好.Abstract: The experiments were conducted under an Ar atmosphere at normal pressure. The results show that the copper content(mass fraction) in steel melt is reduced from 0.6 % to 0.4 % and 0.5 % respectively when ammonium chloride or urea as the decopperizing agents were added to the hot melt.NH4Cl is a better decopperizing agent than HN2CONH2.
