Method of smelting ferronickel in ore-smelting electrical furnace under a layer of charge
Disclosed is a method of smelting ferronickel that comprises the steps of adjusting the depth of the slag bath, the depth of immersion of the electrodes thereinto and the specific power at the electrode surfaces wetted with the slag. According to this method, the depth of the slag bath is maintained...

| description | Disclosed is a method of smelting ferronickel that comprises the steps of adjusting the depth of the slag bath, the depth of immersion of the electrodes thereinto and the specific power at the electrode surfaces wetted with the slag. According to this method, the depth of the slag bath is maintained within the range of from 0.6 to 1.1 of the electrodes diameter, while the depth of immersion of the electrodes and the specific power at the electrode surfaces wetted with the slag are kept at such levels as to provide a mode approaching to the arc mode, but at the same time to that of the ferronickel bath temperature should be adequately high for the free ferronickel tapping. The depth of immersion of the electrodes into the slag bath of 0.1 to 0.25 of the electrode diameter and the specific power at the electrode surfaces wetted with the slag of 5.0 to 6.5 MW/m2 are optimal for the hereinabove mentioned mode. |
