Изобретение относитс к области черной металлургии, конкретнее к способам интенсификации сталеплавильного процесса.The invention relates to the field of ferrous metallurgy, and more specifically to methods for intensifying the steelmaking process.
Известен способ продувки л идкого металла , при котором в металл совместно с кислородом ввод т углеводородное топливо в впде смеси. Подача топлива в дутье снижает температуру реакционной зоны, однако при этом снижаетс и скорость окислени углерода, так как часть кислорода идет на горение топлива .There is a known method of purging a liquid metal, in which hydrocarbon fuel is introduced into the metal in the mixture along with oxygen. The supply of fuel to the blast reduces the temperature of the reaction zone, however, the rate of oxidation of carbon also decreases, since some of the oxygen goes to burn the fuel.
Иаиболее близким по технической сущности и достигаемому эффекту вл етс способ иродувкп жидкого металла, включаюииш введение газообразного окислител в ваппу и углеводородного топлива в виде отдельной от окислительного газа струи.The closest in technical essence and effect achieved is the method of production of a liquid metal, including the introduction of a gaseous oxidant into a wapp and hydrocarbon fuel in the form of a jet separate from the oxidizing gas.
В известном способе углеводородное топливо подаетс над зоной продувки и поэтому оно недостаточно эффективно воздействует на продукты реакций, нротекаюншх. в реакционной зоне, что приводит к интенсивному угару железа и пылевыделению из ванны.In the prior art method, hydrocarbon fuel is supplied above the purge zone and therefore it does not efficiently act on the reaction products that are unsaturated. in the reaction zone, which leads to intense iron loss and dust emission from the bath.
Целью изобретени вл етс сннжение угара железа и уменьшение пылевыделени из ванны.The aim of the invention is to reduce iron loss and reduce dust emission from the bath.
В предложенном способе поставленна задача решена за счет того, что углеводородное топливо ввод т в слои металла, расположенные под реакционной зоной.In the proposed method, the problem is solved due to the fact that hydrocarbon fuel is introduced into the metal layers located under the reaction zone.
Предложенный способ может быть осущ ствлен следующим образом.The proposed method can be implemented as follows.
Углеводородное топливо, например природный газ и кислород, подают в ванну сталеплавильного агрегата через фурму, имеющую сопла, расположенные в два руса. Прпэтом углеводородное топлнво подают в сопла нижнего руса, а кислород - в сопла верхнего руса. В результате углеводородное топливоHydrocarbon fuels, such as natural gas and oxygen, are fed into a bath of a steel-smelting unit through a tuyere having nozzles arranged in two lines. Prpatom hydrocarbon fuel is supplied to the nozzles of the lower rus, and oxygen - to the nozzles of the upper rus. As a result, the hydrocarbon fuel
подают в участки металла, расположепные под реакцнонной зоной, образующейс прн вводе в металл кислорода. Углеводородное топливо при этом после истечени проходит объем металла, наход щийс в реакционнойserved in areas of metal located under the reaction zone formed by the introduction of oxygen into the metal. In this case, the hydrocarbon fuel, after expiration, passes the volume of the metal in the reaction
зоне, и взаимодействует с окислами железа, которые образовались при взаимодействии кислорода с металлом, и восстанавливают их. Одновременно сн 1жаетс температура реакционной зоны, что нрпводит к снижению угара и уменьщению пылевыделени из ванны.zone, and interacts with iron oxides, which were formed by the interaction of oxygen with a metal, and restore them. At the same time, the temperature of the reaction zone is removed, which leads to a decrease in the carbon monoxide and a decrease in dust emission from the bath.
Оитимальный расход углеводородного топлива составл ет 20-40% от расхода кпслорода (ио объему).The total consumption of hydrocarbon fuels is 20-40% of the consumption of oxygen (volume).
