Abstract
Способ автоматического управления качеством конечных продуктов процесса плавки в печи Ванюкова при переработке сульфидной шихты на штейн, включающий получение, анализ и обработку данных АСУ ПВ, контроль состояния процесса по косвенному параметру Qi, разбивку диапазона основного параметра на ряд областей и установление принадлежности основного параметра к одной из областей, сравнение с заданными по технологии пороговыми значениями расхода кислорода, изменения состава и количества шихтовых материалов в зависимости от изменения параметра Q,отличающийся тем,что в качестве основного параметра Qвыбирают удельный расход кислорода на тонну металлосодержащих в м/т, разбивку общего диапазона Qна ряд областей, соответствующих: нормальному течению процесса Qв интервале 150-250 м/т, склонности к холодному течению процесса Qв интервале 150 м/т и ниже, склонности к горячему течению процесса Qв интервале 250 м/т и выше, дополнительно учитывают степень согласованности процесса, выход значений по основному или какому-либо из параметров процесса за границы допустимых режимов области согласованности интерпретируют как конфликт Kи по корректировочным моделям ведут поиск вариантов выхода процесса в область согласованности,а в качестве конфликтов выбраны:K- переокисление металлосодержащих (МС);K- недоокисление МС;K- избыток флюсующих;K- недостаток флюсующих;K- горячий ход печи;K- холодный ход печи;K- невозможность прямого определения температуры расплава в реакционной зоне печи;K- невозможность прямого определения физического объема поступающей шихты, при этом проверяют уровень степени согласованности величин и качества загрузки, A method for automatically controlling the quality of the final products of the melting process in a Vanyukov furnace when processing a sulfide mixture into matte, including obtaining, analyzing and processing ACS PV data, monitoring the process status by the indirect parameter Qi, dividing the range of the main parameter into a number of areas, and establishing whether the main parameter belongs to one from regions, comparison with threshold values of oxygen consumption set by technology, changes in the composition and amount of charge materials depending on the change in param Q, characterized in that the main parameter Q is the specific oxygen consumption per ton of metal in m / t, a breakdown of the total range Q into a number of areas corresponding to: normal process Q in the range of 150-250 m / t, and a tendency to cold process Q in the range of 150 m / t and lower, the propensity for the hot flow of the process Q in the range of 250 m / t and above, additionally take into account the degree of consistency of the process, the output of the values for the main or any of the process parameters beyond the boundaries of the acceptable regimes of the region of agreement values are interpreted as a conflict K, and according to corrective models, they search for options for the process to go into the area of consistency, and the following are selected as conflicts: K - reoxidation of metal-containing (MS); K - underoxidation of MS; K - excess of fluxing agents; K - lack of fluxing agents; K- hot run furnace; K- cold running of the furnace; K- inability to directly determine the temperature of the melt in the reaction zone of the furnace; K- inability to directly determine the physical volume of the incoming charge, while checking the degree of consistency of the values and quality of the load,
