摘要 |
A method capable of suppressing damages to furnace wall refractories in a melting furnace and making the working life of them longer and a technique capable of obtaining a molten iron with homogenized composition while keeping a high productivity upon arc heating a pre-reducing iron in a melting furnace to obtain a molten iron, the method comprising supplying a pre-reducing iron to a stationary non-tilting type melting furnace and melting the iron by an arc heating mainly composed of radiation heating, the melting being performed while keeping a refractory wearing index RF represented by the following equation at 400 MWV/m<2> or less. <DF>RF = P x E/L<2> </DF> Äwherein RF represents the refractory wearing index (MWV/m<2>); P represents an arc power for one phase (MW); E represents an arc voltage (V); and L represents the shortest distance between the electrode side surface of a tip within an arc heating furnace and a furnace wall inner surface (m).Ü <IMAGE> |
