Calculate and obtain the Electrode Fluctuation displacement that the electrode power load variation amount of every phase electrode can be kept symmetrical.Wherein, it is above-mentioned
Circuit in mineral hot furnace is three-phase electrode circuit.
Specifically, in this step, the mineral hot furnace resistance change symmetry model for pre-building is：
It was set up into as follows：With reference to mineral hot furnace typical circuit figure (three-phase electrode circuit) in Fig. 3, setting mineral hot furnace is in smelting
When being in origin state during refining, A phases electrode, the furnace charge operation resistance of B phases electrode and C phase electrodes in three-phase electrode,

Between variation model.
Specifically, when electrode insertion depth produces Δ X displacements by the electrode insertion depth under origin state, according to above-mentioned
(1)~(6) formula, can obtain equation below：
Simplify above formula (7)~(9), obtain：
ΔXa=Cap*dPa……(10)
ΔXb=Cbp*dPb……(11)
ΔXc=Ccp*dPc……(12)

Constant CrIt is unrelated.I.e.：X is respectively by the initial position parameters gathered in step S210ao、XboAnd Xco, electrode active power
Pao、PboAnd PcoAnd above-mentioned (16) formula, just can calculate mineral hot furnace three-phase electrode power termination to be made and realize symmetrical, ore deposit heat
Corresponding each phase Electrode Fluctuation displacement Δ X in stovea、ΔXbAnd Δ Xc, and then (correspondence step S230) is logical in subsequent step
Each phase Electrode Fluctuation displacement of the adjustment mineral hot furnace under origin state is crossed to control the power termination of mineral hot furnace three-phase electrode to change
That measures is symmetrical, the load of three-phase electrode power in mineral hot furnace is reached balance.
It can thus be seen that in the middle of above-mentioned (04) formula and (16) formula, the electrode active-power P in (16) formulaao、
PboAnd PcoWhen equal, (16) formula is changed into (04) formula；Work as Pao、PboAnd PcoWhen equal, each phase Electrode Fluctuation displacement Δ
Xa、ΔXbAnd Δ XcControl each phase Electrode Fluctuation displacement variable symmetrical according to (04) formula, mineral hot furnace reaches optimum state,
And now optimum state and electrode active-power Pao、PboAnd PcoSize is unrelated.

Ra、ΔRbAnd Δ Rc, and above-mentioned resistance change is dynamic value rather than quiescent value, resulting in the line of nonlinear resistance
Property equation, referring to above-mentioned formula (1)~(6).Can be obtained by Fig. 4, Δ Ra、ΔRbAnd Δ RcCorresponding to Δ incremental vector equation is：
Wherein, Δ Uab、ΔUbc、ΔUcaA phases electrode and B phases electrode, B phases electrode and C phases electricity respectively in three-phase electrode
Line voltage between pole, C phases electrode and A phase electrodes, its value is measured value, and unit is V.
Due to operation resistance Ra、Rb、RcVariation delta Ra、ΔRbAnd Δ RcIt is dynamic pure resistance, per phase electrode voltageAnd electric currentPhase is identical, therefore,
Then above-mentioned (17)~(26) represent operation resistance variation delta Ra、ΔRb、ΔRcWith electrode watt current changes delta
Ia、ΔIb、ΔIcModel.
