Изобретение относитс к металлургии, a именно к автоматизации кислородно-конверторного процесса.The invention relates to metallurgy, namely, to the automation of an oxygen-converter process.
Известен способ автоматического управлени процессом продувки в конверторе, основанный на использовании информации о начальных и заданных услови х продувки, причем с целью повышени выхода годного лить измер ют давление газов под куполом камина, температуру факела - на выходе из горловины конвертора и путем обработки этой информации в счетно-решающем устройстве определ ют скорости выгорани углерода, роста температуры, выгорани железа и дожигани СО и COg. По количеству FeO в шлаке управл ют положением фурмы, по коэффициенту использовани кислорода - расходом дуть , a по скорости роста температуры и выгорани углерода - количеством охлаждаюш,их материалов , подаваемых в конвертор, причем после последней добавки эту же функцию выполн ют путем изменени рассто ни сопла фурмы от уровн спокойного металла 1.There is a known method of automatically controlling the purging process in the converter, based on the use of information about the initial and predetermined conditions of blowing, and to increase the yield of the casting, the gas pressure under the fireplace dome is measured, the flame temperature at the outlet of the converter neck and by processing this information the calculating unit determines the carbon burnout rate, temperature increase, iron burnout and the afterburning of CO and COg. In terms of the amount of FeO in the slag, the position of the tuyere is controlled, in terms of oxygen utilization, the flow rate is blown, and in terms of the rate of temperature rise and carbon burnout, the amount of their materials fed to the converter is cooled, and after the last addition the same function is performed by changing the distance tuyere nozzles from the calm metal level 1.
Недостатком известного способа вл етс невысока точность управлени процессом вследствие нестационарности во временн св зи между давлением газов под куполом камина и скоростью окисЛени углерода в саине конвертора, что вызываетс , например, нестационарностью во времениThe disadvantage of the known method is the low accuracy of the process control due to the nonstationarity in the temporal relationship between the pressure of the gases under the dome of the fireplace and the rate of oxidation of carbon in the converter, which is caused, for example, by the nonstationarity in time

Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс способ управлени кислородно-конверторным процессом без дожигани отход щих газов, основанный на измененин положени фурмы и расхода кислорода в зависимости от содержани в отход щих газах двуокиси углерода и расхода продуктов горени , причем степень использовани поступающего в ванну кислорода определ етс по теплопроводности продуктов горени 2.The closest to the invention in its technical essence and the achieved result is a method for controlling an oxygen converter process without post-combustion of flue gases, based on changing the position of the tuyere and oxygen consumption depending on the content of carbon dioxide in the flue gases and the consumption of combustion products, and the degree of utilization the oxygen entering the bath is determined by the thermal conductivity of the combustion products 2.
Недостаток этого способа заключаетс в низкой точности управлени , св занной с большой погрешностью определени расхода продуктов горени .The disadvantage of this method lies in the low control accuracy associated with a large error in determining the consumption of combustion products.
