AbstractThe effects of metal calcium and CaO crucible on deep deoxidation and desulfurization of cast superalloy K417G 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 omega([Ca])-omega([S]) 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 mCaO center dot nAl(2)O(3) slag in the inner wall of CaO crucible, thus realizing deep desulfurization.
