The conditions of thermodynamics and kinetics for molybdenum trioxide reduced by main elements C
Si
Mn and Fe in BOF liquid are analyzed and the adding method of molybdenum trioxide during BOF steelmaking process is discussed. And the commercial production of steelmaking medium carbon cold-heading steel SCM435 (/%:0.35C
0.22Si
0.67Mn
0.003S
0.012P
0.97Cr
0.20Mo) is carried out in an 80t BOF by molybdenum trioxide to replace ferromolybdenum. Results show that the molybdenum trioxide in BOF has excellent reduction condition;in order to prevent evaporation of molybdenum trioxide
it is adding mix with inhibitor lime to insure the yield of molybdenum. The commercial pilot production show that by using molybdenum trioxide the average yield o£ molybdenum is up to 96.65%
