      (click here for purchase;order ; hotline: 86-22-24410619/15822687578    )

       DRI has been applied in all the places such as blast furnace, electric arc furnace, hearth furnace, Oxygen Converter, carburizing furnace and cupola. The application of qualified DRI has been a major issue in the initial tryout by iron and steel plants, casting plants as well as in the selling process of the DRI manufacturers.

       The practical article is written according to the application experience, experiments as well as viewpoints from experts, hoping to your selling and application of the DRI.

1. Application of DRI on Steel Making
1.1 difference between scrap & DRI
1.2 influence of DRI on product performance
1.3 application of DRI on electric arc furnace
    Impact of metallization rate; effect of carbon boil; influence of gangue; influence of electricity factor; influence of noise, influence of DRI on electric arc furnace’s performance

1.6 Application of DRI in domestic iron and steel plants
      Experiment on how different proportion of sponge iron in electric furnace steelmaking affects the time, electricity consumption per ton, liquid steel yield rate and residual elements has been conducted. And many domestic iron and steel plants also precede the research on the proper proportion of sponge iron, expecting to get the ideal result.
