Embodiments in accordance with the present invention, reducing agent can be solid reductant, liquid reducer or gaseous reducing agent.
In addition it is also necessary to further illustrate, the material of every lance ejection is not particularly limited, and can be oxygen-enriched
At least one of gas and reducing agent and optional concentrate miberal powder, i.e., one spray gun, can spray oxygen rich gas, reducing agent
With any one in concentrate miberal powder or wherein any two kinds of combination, or injection oxygen rich gas, reducing agent simultaneously
With concentrate miberal powder.The regulative mode of the species of the injecting substances of spray gun and the ratio of each material is not particularly limited, for example, can
Condition is carried out with the species of the aliment of the feeding pipe by adjusting spray gun and ratio, can also be by adjusting the spray in spray gun
The structure for penetrating pipeline is adjusted, and can also carry out condition by adjusting the quantity for the spray gun for spraying each material.
Embodiments in accordance with the present invention, the insertion angle of spray gun is not particularly limited, and those skilled in the art can root
It is adjusted according to production needs.According to some embodiments of the present invention, spray gun 300 is straight at 0-30 degree angles.Specifically, spray
Rifle 300 is downwards that level is downward into 0-30 degree angles, the i.e. opening of angle with level, so that, ejecta sprays downwards, with slag blanket
In material good mixing effect.According to the preferred embodiment of the present invention, spray gun 400 is straight at 0-15 degree angles.Thus,
The ratio that ejecta enters slag blanket is high, prevents that the spray angle of ejecta is excessive, ejecta is entered matte layer, thus ejecta with
The mixed effect of material in slag blanket is more preferably.
Embodiments in accordance with the present invention, spray gun 300 further comprises：Threeway jet pipe, the threeway jet pipe is arranged on spray gun 300
Gun body in, and threeway jet pipe seals by ball valve.Thus, air port can be disclosed with hammer drill, no spray gun can be used very easily
Drill rod is blocked.
Electrode 500：Embodiments in accordance with the present invention, the electrode 500 is inserted into electrode jack 131 and extend into decanting zone
In interior slag blanket ZC.Thus, electrode is that decanting zone carries out heat supply, decanting zone cooling influence sedimentation separation effect is prevented, so as to have
The rate of recovery of valency metal is higher.
Embodiments in accordance with the present invention, electrode jack is multiple, that is to say, that may be inserted into multiple electrodes.Thus, it is heavy
Drop area and sufficient heat is provided, to prevent slag and sulfonium body from solidifying, influence sedimentation.
In the description of this specification, reference term " one embodiment ", " some embodiments ", " example ", " specifically show
The description of example " or " some examples " etc. means to combine specific features, structure, material or the spy that the embodiment or example are described
Point is contained at least one embodiment of the present invention or example.In this manual, to the schematic representation of above-mentioned term not
Necessarily refer to identical embodiment or example.Moreover, specific features, structure, material or the feature of description can be any
One or more embodiments or example in combine in an appropriate manner.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that：Not
In the case of departing from the principle and objective of the present invention a variety of change, modification, replacement and modification can be carried out to these embodiments, this
The scope of invention is limited by claim and its equivalent.
