METHOD OF CONTROLLING PRODUCTION EEATERS NS OF SUBMERGED-ARC FURNACE FOR OBTAINING PHOSPHORUS

摘要

METHOD FOR CONTROL ELEKTROTEHNOLOgaChESKIM closed mode, an electric furnace FOR PHOSPHORUS, where maintained during melting resistance furnace phases within a predetermined range by moving electrode arms with electrodes and bypass the electrodes relative to the electrode holder and the magnitude of the bypass is determined proportional to the amount of electric power inputted to each electrode for the time between perepuskamts of tl and h ay and with the fact that, in order to increase the productivity of the furnace and the reliability of the electrodes by holding the optimal position of the electrodes, determining the position of the electrode holders in the period. between the by-passes, averaging it over this period and comparing with the given one, determining the slag content between the by-passes, averaging it over this period and comparing with the given one and passing the electrodes after a period of -4 3.6 - 3.65 -10, m, PC ID - diameter of the electrode, cm; where L is the specified value of the bypass, cm; n is the number of electrodes; PJ, - predicted average (L power for the time between reloads, MW; by the corrected value P. yil, see RSyu, where W1i is the amount of electricity introduced into the electrode during the period by the restarts, WITH MW / h; L1 - reduced to a given value of 4 a) disagreement; - coefficient of dependence depending on L 8 Dc - reduced to a given value of the mismatch; o (, 2 is a coefficient depending on 4C.
