To achieve higher productivity of arc furnace, we reconsider to reduce the oxidation period. As the result, we obtained a new operation process that is blowing oxygen into arc furnace with supplying power.Operation tests in 2-ton and 5-ton arc furnaces with automatic electrodes control system were tested. The results of operation tests are as follows;(1) A good heat efficiency of electric energy during oxygen blowing was obtained by the new process.2-ton arc furnace 75.5% (700kW)5-ton arc furnace 65.2% (1000kW)Above written are rough heat efficiencies including heat caused by oxidation.(2) New operation has no problem except catching carbon.(3) Electrode consumption is as almost same as that of the ordinary process.(4) Using the new process, arc furnace oxidation period is possibly reduced by 10-15min.
