摘要
提出了用喂丝法向钢液中插入铵盐或氨基化合物的脱铜方法．在常压下，Ar气氛中，向钢液中分别加入NH4Cl和NH2CONK2把约300g钢水含铜量从0．6％降至0．47％～0．5％，仅用脱铜剂2～4g．氯化铵有氯化和铵分解的双重脱铜作用，比尿素脱铜效果更好．
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.
