Изобретение относитс к черной металлургии , в частности к контролю состава ванны сталеплавильного агрегата.This invention relates to ferrous metallurgy, in particular to controlling the composition of the bath of a steelmaking unit.
Известны способы контрол содержаний углерода в сталеплавильной ванне при расплавлении скрапа по анализу проб металла и вибрации корпуса агрегата 1, 2. Однако такие способы не решают проблему контрол при высоком содержании углерода и в случае отсутстви у агрегата металлического корпуса (например, двухванные печи).There are known methods for controlling the carbon content in a steelmaking bath when melting scrap by analyzing metal samples and vibrations of the aggregate housing 1, 2. However, such methods do not solve the problem of controlling when the carbon content is high and if the aggregate does not have a metal enclosure (for example, twin-furnaces).
Наиболее близким к описываемому изобретению по технической сущности и достигаемому результату вл етс способ контрол сталеплавильного процесса, включающий отбор п анализ пробы металла, а также измерение напр жени на нагрузке в цепи электрод- расплав - кладка - металлоконструкции агрегата 3.The closest to the described invention according to the technical essence and the achieved result is a method of controlling the steelmaking process, including sampling and analysis of a metal sample, as well as measuring the voltage on the load in the electrode – melt – masonry – metalworking circuit of the unit 3.
К недостаткам известного способа относитс низка точность контрол , св заниа с тем, что измерени производ т без св зи во времени и не используют полезную информацию, содержащуюс в результатах измерений, дл получени представительного значени содержани углерода в ванне агрегата.The disadvantages of the known method are low control accuracy, due to the fact that measurements are made without communication in time and do not use useful information contained in the measurement results to obtain a representative value of the carbon content in the aggregate bath.
Целью изобретени вл етс повышение тредставительности и точности контрол при наличии нерасплавивщегос скрапа. Это достигаетс тем, что моменты отбора пробы М измерени напр жени в цепи электрод-расплав-кладка-металлоконструкции агрегата совмещают п корректируют результаты анализа пробы но значению напр жени в следующем соотнощении:The aim of the invention is to increase the accuracy and accuracy of control in the presence of non-melting scrap. This is achieved by the fact that the moments of sampling M measuring the voltage in the electrode – melt – masonry – metalwork circuit of the unit combine and correct the results of the analysis of the sample but the voltage value in the following ratio:
-1-one
G -(а + bU)G - (a + bU)
С CLCL
где С, - содержание углерода в ванне печи и содержание углерода в пробе металла; G - масса шихтовых материалов;where C, is the carbon content in the furnace bath and the carbon content in the metal sample; G is the mass of charge materials;
а, b - экспериментально определ емые коэффициенты; и - напр л ение на нагрузке в электрической цепи.a, b are experimentally determined coefficients; and - voltage on the load in the electric circuit.
Вследствие наличи нерасплавивщегос скрапа содержание углерода в пробе существенно отличаетс от усредненного содержани углерода во всей металлической ванне. Измерение напр л ени в цени электрод-Due to the presence of non-melting scrap, the carbon content of the sample is significantly different from the average carbon content of the entire metal bath. Measurement of voltage in price
расплав-кладка-металлоконструкции агрегата позвол ет в момент отбора пробы определ ть тепловое состо ние агрегата, тесно св занное с количеством нерасилавившегос скрана. Таким образом, коррекци результатов анализа пробы по значению напр жени в токовой цепи обеспечивает получение представительной величины, содержани углерода во всей ванне печи, включа скрап, который науглероживаетс иосле полного расплавлени . Применение способа при прогнозировапии содержани углерода в сталеплавильных агрегатах повышает точность прогноза.The melt-clutch-metalwork of the unit allows, at the time of sampling, to determine the thermal state of the unit, which is closely related to the amount of non-expanded skran. Thus, the correction of the sample analysis results by the voltage value in the current circuit provides a representative value, the carbon content in the entire furnace bath, including scrap, which is carburized after complete melting. The application of the method in predicting the carbon content in steel-smelting aggregates increases the accuracy of the forecast.
