Изобретение отл-юситс к области пнрометаллургичеоких процессов цветной металлургии .The invention is excellent in the field of the pnerometallurgical processes of nonferrous metallurgy.
Известен способ управлени процессами переработки цинксодержащих материалов в трубчатой вращающейс печи, базируютс на использовании локальных систем стабилизации отдельных входных и |режимных параметров техиологического процесса, предусматривающий стабилизацию весовой дозировки рудмой части шихты в печь, с поддержанием в заданном к ней .соотношении дозировки топливной части шихты-коксика, автоматическое регулирование т гового режима и стабилизацию температуры по зонам печи.The known method of controlling the processing of zinc-containing materials in a tubular rotary kiln is based on the use of local stabilization systems for individual input and regime parameters of the technological process, which involves stabilizing the weight dosage of the ore portion of the mixture into the kiln, maintaining the dosage of the fuel portion of the charge set to it coking, automatic regulation of the traction mode and temperature stabilization in the zones of the furnace.
Однако гв известном способе управлени процессом, установка заданий регул торам производитс печевым вручную по субъективным факторам (в зависишости от состо ни печи, хода технологического процесса, цвета пламени в нижней головке печи и др.), а также 1на основе сопоставлени показаний отдельпых приборов автоматического контрол . Поскольку выходные параметры процесса (потери циНка и углерода с клинкером, степень растворимости получаемых возгонов) завис т от целого р да переменных величин процесса (темиературы по зонам печи, величины разрежени в печи, величины дозировки компо-нептов шихты, содержани цинка в However, a known process control method, setting the tasks to the controllers is done manually by baking according to subjective factors (depending on the furnace state, process flow, flame color in the lower furnace head, etc.), as well as by comparing the readings of individual automatic control devices . Since the output parameters of the process (loss of zinc and carbon with clinker, the degree of solubility of the sublimates obtained) depend on a whole number of process variables (measurements on the furnace zones, the vacuum density in the furnace, the dosage of the components of the charge, zinc content
шихте в др.), св занных различной величиной динамических каналов, то прогнозирование выходных пара.метров довольно сложно, и процесс корректируетс только после по влени недопустимых по технологическим услови м отклонений от нормы.charge in others), connected by different size of dynamic channels, the prediction of output meters is quite difficult, and the process is adjusted only after the occurrence of deviations from the norm that are unacceptable by technological conditions.
Большие времена запаздываний -по кавалам , св зывающим выходные параметры с управл ющими, привод т к значительным перерегулироеани м процесса при таком способе упраЕленп . Технологический процесс зачастую протекает не при оптимальных услови х и зав;;сит от навьжов и опыта печевого.Longer lag times — for cavals that associate output parameters with controllers — result in significant process overshoots with this control method. The technological process often takes place not under optimal conditions and the head ;; sieve from the navigations and experience of the furnace.
Цель ; зобретени - созданпе способа управлени процессом, обеспечивающего автоматичес1-:ую корректировку задани регул торам стабилизации входных и режимных величии процесса при изменении состава и свойстз шихты, а также условий протекани процесса, обеспечива при этом оптимальную величину загрузки пшхты в печь при минимальных издержках производства и качественных похазагелей выходных продуктов не хуже заданных.Purpose ; The invention has created a process control method that provides automatic adjustment of the task of regulating the stabilization of the input and mode magnitudes of the process when the composition and properties of the charge change, as well as the process conditions, while ensuring the optimum amount of charge in the furnace at minimum production costs and quality Pohazagely output products are not worse than specified.
Это достигаетс тем, что на основе исследований технолог 1ческого процесса составл ют его статичсгкую модель относительно выходных величин процесса. Контролиру величину содержани цинка, в поступающей на нерерабогку в печь шихте и содержапие изThis is achieved by the fact that, on the basis of research, the process technologist makes his static model relative to the output values of the process.
