In this paper, the thermodynamic properties of Fe-Ce-NO and Fe-YNS solutions in the range of 1570-1650 ℃ are studied. The main results are as follows: (1) Cerium and yttrium increase the solubility of nitrogen and oxygen slightly increase the solubility of nitrogen and sulfur Slightly reduce the solubility of nitrogen; (2) Cerium, yttrium, oxygen, sulfur and nitrogen interaction coefficient and temperature relationship. e_N ~ (Ce) = (-6230 / T) +2.670, e_N ~ Y = (- 6640 / T) + 2.986, e_N ~ O = (-3497 / T) +1.650, e_N ~ S = 264 / T-0.128 ; (3) the denitrogenation products of cerium and yttrium are CeN and YN; (4) the relation between the denitrogenation constant of cerium and yttrium is related to the temperature: 1gK_ (CeN) - (- 20960 / T) + 7.972,1gK_ (YN) 20440 / T) +7.863.
