METHOD AND DEVICE FOR PRODUCING MOLTEN IRON |
摘要 |
<p>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/m2 or less. RF = P x E/L2 [wherein RF represents the refractory wearing index (MWV/m2); 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).] 30</p> |
