摘　　要：在实验室条件下研究了1300℃下Mn—Fe—C 熔体中加入 BaCO_3后的脱磷脱硫过程,同时研究了 BaCO_3加入量对熔体脱磷的影响,BaO 渣中 MoO 的溶解以及渣中 BaO 对磷分配比的影响。实验证明 BaCO_3是锰基合金有效的脱磷、脱硫剂.Dephosporization and desulphurization of Mn-Fe-C melts adding BaCO_3 were investigated at 1300℃ under laboratory conditions.The effcct of the adding amount of BaCO_3 and the content of BaO in slag upon dephosphization and the dissolving amount of MnO in BaO base slag were ascertained.The experimcntal esults purpost that BaCO_3 is one of effective dephosphorizing agents for Mn- base alloys.
