Description
Изобретение касаетс теплового регулировани доменной плавки и может использоватьс в черной металлургии.The invention relates to heat control of a blast furnace smelting and can be used in ferrous metallurgy.
Наиболее близким к предлагаемому изобретению по технической сущности и достигаемым результатам вл етс способ регулировани доменной плавки, включающий измерени параметров колощникового газа и воздействи па параметры шихты и дуть 1.Closest to the proposed invention in its technical essence and the achieved results is a method of controlling blast furnace smelting, including measurements of the parameters of the collar gas and the effect of the parameters of the charge and blowing 1.
Однако этот способ требует особо точного измерени нескольких составл ющих колощникового газа (погрещность измерени СО, СОа, НгМ и СН4 от верхнего предела не должна превыпшть ±0,5%). Из-за неоднозначности расщифровки причин из.менени каждой из составл ющих газа возникают дополнительные ощибки в расчете величин регулирующего воздействи . Способ невозможно примен ть при неустанозивщемс ходе печи и не обеспечиваетс непрерывный контроль использовани газового потока и его стабилизации. Кроме того, способ сложен при реализации и требует существенных капитальных затрат (необходима математическа модель, ЭВМ, стоимость аналитической установки только дл анализа состава колощникового газа повыщенной-точности составл ет 100 тыс. руб.).However, this method requires particularly accurate measurement of several components of the collar gas (the measurement error of CO, CO, HgM and CH4 from the upper limit should not exceed ± 0.5%). Due to the ambiguity of deciphering the reasons for the change in each of the components of the gas, additional errors arise in the calculation of the values of the regulating action. The method cannot be used in the case of an unmanaged progress of the furnace and continuous monitoring of the use of the gas stream and its stabilization is not provided. In addition, the method is difficult to implement and requires substantial capital expenditures (a mathematical model is needed, a computer, the cost of the analytical setup for analyzing the composition of the collar gas of higher-accuracy gas is 100 thousand rubles only).
Цель изобретени - улучщение качества регулировани и технико-экономических показателей плавки за счет оперативного вы влени отклонений доменного процесса от норм ы.The purpose of the invention is to improve the quality of regulation and technical and economic indicators of smelting by quickly detecting deviations of the blast furnace process from standards.
Дл этого непрерывно измер ют теплотворную способность отход щего из печи газа и при превышении ее на 1,0% и периодеTo do this, the calorific value of the gas coming out of the furnace is continuously measured and, if it is exceeded by 1.0% and the period
отклоненн 0,25-1,0 времени пребывани щихты, умепьщают соответственно рудную нагрузку на 0,3-0,7%, либо влажность дуть на 2-6г/м, а при понижении теплотворной способности колощникового газа на 1% и периоде отклонени 1,0-2,0 времениrejected 0.25–1.0 times of residence of the poor, reduce the ore load by 0.3–0.7% respectively, or the humidity blow by 2–6g / m, and when the calorific gas calorific value decreases by 1% and the deviation period 1 , 0-2.0 times
пребывани щихты. увеличивают соответственно расход природного газа на 0,1-0,2% но отнощению к объему дуть , либо расход мазута на 0,7-1.1 г/м дуть .stays shchychita respectively, the consumption of natural gas is increased by 0.1-0.2%, but relative to the volume of the blow, or the consumption of fuel oil by 0.7-1.1 g / m blow.
