| Abstract: | Two-step smelting reduction method is used to restore the Baosteel＇s OMC powder fluidization. Amalyze the impact of temperature,line speed,the percentage of H2 in reduction gas on the rate of metallization. The rate of metal-based primary and secondary factors is studied by range analysis method.The results show that the best pre-reduction process parameters as follows： reduction temperature to 800 ℃, line speed of 0.8 m/s. |
