Изобретение относитс к способам регулировани рудной нагрузки на кокс в доменной печи и может быть использовано в черной металлургии.This invention relates to methods for controlling the ore load on coke in a blast furnace and can be used in ferrous metallurgy.
Наиболее близким по технической суш ности и достигаемому результату к предлагаемому вл етс способ регулировани рудной нагрузки на кокс в доменной печи в зависимости от изменени содержани железа в шихте и влажности кокса 1 .The closest in technical dryness and the achieved result to the proposed is a method of controlling the ore load on the coke in a blast furnace depending on the change in the iron content in the charge and the moisture content of coke 1.
Недостатком этого способа вл етс отсутствие учета динамики доменного процесса при определении момента начала регулировани при изменении характеристик шихты, включа влажность кокса , что ухудшает технико-экономические показатели доменной плавки и качество выплавл емого чугуна.The disadvantage of this method is the lack of consideration of the dynamics of the blast furnace process in determining the start of regulation when the charge characteristics change, including the moisture content of coke, which degrades the technical and economic indicators of blast furnace smelting and the quality of the pig iron produced.
Цель изобретени - повьпление качества чугуна и снижение расхода кокса.The purpose of the invention is to improve the quality of cast iron and reduce the consumption of coke.
Поставленна цель достигаетс тем, что при изменении содержани железа в шихте .более чем на 0,4 абс % или влажности кокса более чем на 0,3 абс %The goal is achieved by the fact that with a change in the iron content in the charge of more than 0.4 abs% or the moisture content of coke more than 0.3 abs%
от заданных, измен ют рудную нагрузку на О,012-0,016 единиц от ее значений перед изменением параметров через врем в часах после превышени , равное отношению абсолютных величин 1,2-1,3 и 0,9-1,2 к соответствуюшему изменению параметра, причем при увеличении параметров рудную нагрузку уменьшают, а при уменьшении - увеличивают.from the given, the ore load is changed by O, 012-0.016 units from its values before changing parameters through time in hours after exceeding, equal to the ratio of absolute values 1.2-1.3 and 0.9-1.2 to the corresponding change in parameter , moreover, with an increase in the parameters, the ore load is reduced, and with a decrease, it is increased.
