The principle of work of this device is, first and second electric current, voltage and the power signal that collect carry out calculating, comparing by PLC device 1, and design according to the characteristic of institute's ferroalloy smelting product and the carrying out of technological requirement to voltage, electric current and power, the power control profile that setting is best, select optimal regulative mode, and according to mathematical model and setup parameter, carry out computational analysis, eventually through PLC output module, be sent to the proportioning valve amplification board (or frequency converter of drive motor) controlling motor lifting, be with moving electrode to move up and down with drive unit 10.
In ferroalloy smelting, owing to being heated by the contact of electrode and furnace charge and discharging, resistance heat and arc heat may be there is simultaneously.At the power transmission initial stage, electrode bottom is embedded in furnace charge.Its heating is from electric arc, but the mainly resistance heat of electric current by producing during furnace charge.Now Charging Stock Used is poor, electric current changes from small to big, curent change fast, and three-phase load curent change is violent.It is the most reasonable that this stage selects power to control.Regulator according to the power parameter conservative control output current of one-time detection, makes electrode be in rational position while regulating secondary current change, ensures that the power be input in stove is maximal value.After furnace charge melts formation molten bath, because the electric conductivity of melt strengthens, charging resistance reduces, and substantially enter arc heated, stepping on material, turning over the phenomenon such as slag, boiling easily appears in this stage.Rise fall of electrodes is sensitiveer, with against short-circuit.After furnace charge melts completely, enter smelt with arc completely, now can enter impedance-controlled fashion according to setting, by regulating the lifting of electrode, controlling the change of electric arc, electric current and voltage, making electrode power by given curve motion.
Impedance Principles of Regulation are:
