METHOD OF AUTOMATIC CONTROL OF MELTING PROCESS OF COPPER-NICK SULPHIDE RAW MATERIAL IN VANYUKOV'S FURNACE DURING SULPHIDE CHARGE PROCESSING TO REGULUS

FIELD: metallurgy.SUBSTANCE: invention relates to the method of the automatic control of the melting process of copper-nick sulphide raw material in Vanyukov's furnace during sulphide charge processing to regulus. The method includes permanent monitoring of the process parameters, correction of the control parameters to stabilize the copper content, at that as the main parameter Qthe specific flowrate of the oxygen per tons of only contained metals in m/t, division of the entire Qrange to some areas corresponding to: normal process execution Qin range 150-250 m/t, ability for cold process Qin range 150 m/t and below, ability for hot process Qin range 250 m/t and over, additionally degree of the process consistency is considered, value of main or any other parameter beyond the limit modes of the consistency area is interpreted as conflict K, and as per the correction models the options are searched for the process return in the consistency are, the following is selected as conflicts: K- overoxidation of contained metals (MC), K- underoxidation of contained metals , K- excess of fluxings, K- lack of fluxings, K- hot furnace condition, K- cold furnace condition, K- impossibility of direct determination of the melt temperature in the furnace reaction zone, K- impossibility of the direct determination of physical volume of the supplied charge, at that decree of consistency of the values and quality of charge, blasting modes with the set copper content in regulus is checked as per the polynomial models.EFFECT: operative control of the melting process, process visualization, quality stabilization of the melt products, acquisition of the not measured or poorly measured process parameters, and estimation of the machine status by the indirect measures, reduced power consumption of the charge processing, stabilization of the process temperature mode upon keeping the set targets and objectives, and production of the software product.3 dwg, 2 ex Изобретение относится к способу автоматического управления процессом плавки медно-никелевого сульфидного сырья в печи Ванюкова при переработке сульфидных шихт на штейн. Способ включает постоянный контроль параметров процесса, корректировку управляющих параметров для стабилизации содержания меди, причем в качестве основного параметра Qвыбирают удельный расход кислорода на тонну только металлосодержащих в м/т, разбивку общего диапазона Qна ряд областей, соответствующих: нормальному течению процесса Qв интервале 150-250 м/т, склон
