Abstract：Through analyzing the existing condition of energy and dielectric of melting process, to decrease the consumption of energy and dielectric and increase reclaiming energy, some measurements have been adopted, such as gas from converter can be made and use by ourselves and redundant gas connected with pipe network; increasing the use level of vapour; accelerating the cycle of ladle; optimizing the parameter oxygen lance; circulating and using the polluted water. The results showed that the energy consumption has been decreased, secondary energy sources have been full used, the cost of production has been reduced and the environment pollution has been reduced.
