Abstract：A new smelting method was raised that molybdenum trioxide instead of ferromoly, was added to AOD furnace for 316L stainless steel. Based on the new method, thermodynamics of reduction of molybdenum trioxide was analyzed by the main elements in the AOD bath，the reduction mechanism of MoO3 was discussed and the formula of its reduction rate was deduced. In addition, it was involved that how the moly-oxide was put into the AOD furnace. There was a brief account of industrial practice in which moly-oxide was used for the refining of 316L stainless in AOD furnace. It shows that on one hand, the moly-oxide AOD furnace possesses excellent condition for the reduction of moly-oxide, for which reason it will be completely reduced in half an hour, on the other hand, it is better to utilize moly-oxide composite pellet containing moly-oxide, reductant and inhibitor for steady and safe refining process and the best use of moly- resource.
