Изобретение относитс к области черной металлургии.This invention relates to the field of ferrous metallurgy.
Известны способы контрол выбросов из кислородного конвертера во врем продувки, включающие определение момента начала выбросов и измерение амплитуды и частоты пульсаций интенсивности свечени факела.Methods are known for controlling emissions from an oxygen converter during purging, including determining the moment of onset of emissions and measuring the amplitude and frequency of pulsations of the glow intensity of a torch.
К недостаткам известных способов относитс низка точность определени массы выбросов, которую можно характеризовать как полуколичественный контроль.The disadvantages of the known methods are the low accuracy of determining the mass of emissions, which can be characterized as a semi-quantitative control.
С целью увеличени точности контрол по предлагаемому способу интегрируют по времени отношение амплитуды к частоте пульсаций « определ ют массу выбросов как произведение полученного интеграла на переменный по времени продувки масштабный коэффициент .In order to increase the control accuracy of the proposed method, the time-to-amplitude-to-ripple-ratio is determined by defining the mass of emissions as the product of the obtained integral and the time-variable purge scale factor.
Момент начала выбросов определ ют любым известным способом - по уровню интенсивности свечени факела, по характерному изменению шума продувки и т. п.The moment of onset of emissions is determined by any known method - according to the level of intensity of the glow of the torch, by the characteristic change in the noise of the blowdown, etc.
Начина с этого момента, выдел ют из сигнала датчика интенсивности свечени переменную составл ющую, определ ют амплитуду и частоту пульсаций, относ т значение амплитуды к частоте. Полученное значение характеризует интенсивность выбросов, котора увеличиваетс с увеличением этого отношени . Интегриру эту величину по времени и умножа результат в конце периода выбросов на экспериментально определенный коэффициент , переменный по ходу продувки, определ ют массу металла и шлака, выброшенных из конвертера за этот период.Starting from this moment, the variable component is extracted from the luminous intensity sensor signal, the amplitude and frequency of the pulsations are determined, and the value of the amplitude is related to the frequency. The value obtained characterizes the intensity of the emissions, which increases with an increase in this ratio. Integrating this value over time and multiplying the result at the end of the emission period by an experimentally determined coefficient that varies along the course of purging determines the mass of metal and slag emitted from the converter over this period.
