Description
Известны различные способы получени спекаемых материалов из железных руд, известн ка и углеродистого восстановител с содержанием окиси кальци до .Various methods are known for producing sintered materials from iron ores, limestone and a carbonaceous reducing agent with calcium oxide content up to.
Предлагаемый способ иозвол ет получить железо-известковый спек с содержанием окиси кальци до 90-о.The proposed method allows to obtain an iron-lime cake with a calcium oxide content of up to 90 o.
Дл получ -н такого железо-нзвесткового спска все состав.ч юнхие шихты-железную руду, известн к и твердый углеродистый восстаиовнтель (тонщй уголь, антрацит, кокс)тоико H3MO.Ui4aioT, тигатс.пьно нсремешивают , окомковывают и комки подвергают высокотемпературному обжигу при темнерату|)е НПО 1400°/In order to obtain such an iron-mineral grade, all the components of the charge-iron ore are known, and the carbon solid carbonate (thin coal, anthracite, coke) of H3MO.Ui4aioT carbon monoxide, tigats. tenerutu |) e NGOs 1400 ° /
При этих услови х железо частично восстанавливаетс н образует в комках металлический скелет.Under these conditions, iron is partially reduced and the metal skeleton is formed in lumps.
С целью интенсификации процесса выи.чавки чугуна и стали, полученные онисывае П:| м спосооом железоизвестковые комки могут иримен тьс взамен известн ка в доменной и взамен известн ка н извести ири выилавке стали, а также в качестве офлюсовател при ироизводствс оф.иосованпого аг.чомерата.In order to intensify the process of casting iron and steel, it is obtained by casting: | By means of iron ore lumps, they can be used instead of limestone in a blast furnace and instead of limestone in a limestone and a steelmaking system, and also as a fluxifier in the industry of.iosovanpogo ag.chomerate.
Предмет и з о б р е т е н н Subject and purpose of
Способ по.чучеии же,тезо-известкового снека из тонко измельченHoii смеси железной руды, известн ка и углеродистого восстановител в внде комков, о т л н ч а ю . и и с тем, что. с целью получени прочных комков, CHOco6Hijix выдерживать продо;1жигел1 ное храиение, комки подвергают обжигу при температуре 1100--1400 с чacтичны r восстановлением железа, образуюн1,нм в комке металлнческий скелет.The method is similar to that of a lime lime snack made from a finely crushedHoii mixture of iron ore, limestone and a carbonaceous reducing agent in lumps, about 20 ml. and with that. in order to obtain strong lumps, CHOco6Hijix to withstand food; 1 liter storage, lumps are subjected to firing at a temperature of 1100–1400 with partial iron reduction, forming a 1nm in a lump of metal skeleton.
