Abstract采用真空感应熔炼的方法研究了金属钙和氧化钙坩埚对铸造高温合金K417G深度脱氧和脱硫的影响。结果表明,Ca能够达到深度脱氧脱硫的效果,可将氧含量(质量分数,下同)由0.0013%降低到0.0006%,硫含量由0.0007%降低到0.0002%,并且合金中实测的ωCa-ωS平衡关系与热力学计算结果基本一致;此外,CaO坩埚的脱氧脱硫效果明显,氧含量可降至0.0006%,硫含量可降至小于0.0002%,硫含量的降低与氧化钙坩埚内壁形成了mCaO·n Al2O3渣有关,从而实现深度脱硫。
Other AbstractThe effects of metal calcium and CaO crucible on deep deoxidation and desulfurization of cast superalloy K417 G were studied by vacuum induction melting. Results show that Ca can achieve the effect of deep deoxidation and desulfurization, the oxygen content decreases from 0.0013% to 0.0006%, and the sulfur content decreases from 0.0007% to 0.0002%. The equilibrium relationship between measured ωCa-ωS in the alloy is basically the same as that of the thermodynamic calculation. In addition, the effect of CaO crucible on deoxidation and desulfurization is obvious. Oxygen content can be reduced to 0.0006%, and sulfur content can be reduced to less than 0.0002%. The reduction of sulfur content is related to the formation of m CaO·n Al2O3 slag in the inner wall of CaO crucible, thus realizing deep desulfurization.
