钢液气化脱铜
Decopperization in Steel Melt by Gasification

摘要: 在1600℃、常压Ar气氛下,向钢液中分别加入NH4及(NH4)2C2O4,将400g钢水含铜量从0.5%分别降至0.31%及0.38%仅用脱铜剂07~0.8g.然而,如果不降低体系的压力,在相同条件下用铵盐脱铜很难将钢含量降至0.30%以下.Abstract: The experiments were carried out at 1 600℃ and normal pressure under an Ar atmosphere. The result showed that the copper content (mass fraction) in steel melt of 400g was reduced from about 0.5% to 0.31% and 0.38% respectively when 0.7~0.8g of NH4Cl or (NH4)2C2O4 as the decopperizing agents added to the melt. However it is very difficult to reduce the copper content below 0.3% without reducing the pressure of the reaction system.
