摘要
研究了在真空感应炉中使用 Ca O坩埚熔炼镍基高温合金的脱氧效果 ,分析了加入 0 .0 2 % C、0 .5 % Al对脱氧的影响。结果表明 :采用 Ca O坩埚 ,选择合适的熔炼工艺及 C、Al加入量 ,可使氧的含量降低到小于 0 .0 0 0 6%
The deoxidation effect of VIM refining Ni-base superalloy by using CaO crucible was studied.The influence of adding 0.02%C and 0.5%Al on deoxidation was also analyzed.This study showed that adopting proper refining technology and carbon and aluminium addition amount,oxygen content could be reduced to below 0.0006%.
