喂丝法钢液脱铜

Decopperization in Steel Melt with Wire-feeding

    摘要
  • 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.

     

    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.
