Abstract

Abstract

According to current smelting conditions of Chengde Steel and by taking its BF slag as samples,effects of the addition of CaF₂,MnO,Li₂O,MgO or Cr₂O₃ to final slag on melting properties of the slag were studied with melt property tester RTW.The result shows that all of the additives are helpful to reduce the viscidity of slag.With the addition amount of CaF₂ of 0.5%~1.0%,MnO of 1.0%,MgO of 3%,Cr₂O₃ of 0.5%,or Li₂O of 1.0%,the best dilution effect is achieved.With an addition amount of 0.5%,the additives listed in order of decreasing effect are Li₂O,CaF₂,MgO,Cr₂O₃ and MnO.
