Изобретение относитс  к области черной металлургии.This invention relates to the field of ferrous metallurgy.

Известен снособ вынлавки технически чистого железа в нромышлениых агрегатах. Так, например, окисление углерода на заключительных Этапах плавки производ т нрисадками больших норций железной руды и продувкой металлической ванны техническим кислородом или воздухом с носледуюш:еР1 обработкой металла печным окислительным шлаком. Окисление углерода при его низких концентраци х - менее 0,03-0,02% - представл ет большие технологические трудности и требует большого количества времени и материальных затрат.Known snozov vylavki technically pure iron in nromyshlenyh aggregates. For example, the oxidation of carbon in the final stages of smelting is performed by the use of large amounts of iron ore and the blowing of a metal bath with technical oxygen or air with the following: eP1 metal treatment with furnace oxidizing slag. The oxidation of carbon at its low concentrations — less than 0.03–0.02% — presents great technological difficulties and requires a large amount of time and material costs.

С целью интенсификации процесса обезуглероживани  и обеспечени  содержани  углерода в расплаве не более 0,015% по предлагаемому способу в процессе продувки по достижении содержани  углерода 0,03-0,08% в расплав ввод т никель в количестве 1,5-2,5% от веса расплава.In order to intensify the decarburization process and ensure the carbon content in the melt is not more than 0.015% by the proposed method, during the purging process, when the carbon content reaches 0.03-0.08%, nickel in the amount of 1.5-2.5% by weight is added to the melt. melt.

После присадки никел  производитс  дальнейша  продувка металла кислородом илиAfter the addition of nickel, the metal is further purged with oxygen or

кислородсодержашими смес ми. В результате повышени  термодинамической активности углерода его дальнейшее окисление ускор етс .oxygenated mixtures. As a result of an increase in the thermodynamic activity of carbon, its further oxidation is accelerated.

Продувка заканчиваетс  после достижени  требуемых - ниже 0,015% - содержаний углерода . Полученна  низкоуглеродиста  сталь с содержанием углерода менее 0,015% и никел  1,5-2,5% может быть иснользована как шихтова  заготовка дл  производства сталей и сплавов специального назначени  или как готовый металл.Blowing is completed after the required carbon content is reached - below 0.015%. The obtained low carbon steel with a carbon content of less than 0.015% and nickel 1.5-2.5% can be used as a billet for the production of steels and alloys for special purposes or as a finished metal.

Предмет изобретени Subject invention

Способ выплавки стали с низким содержанием углерода, включаюший продувку расплава кислородом, отличающийс  тем, что, с целью интенсификации процесса обезуглероживани  и обеспечени  содержани  углерода в расплаве не более 0,015%, в процессе продувки по достижении содержани  углерода 0,03-0,08% в раснлав ввод т никель в количестве 1,5-2,5% от веса расплава.The method of steel smelting with low carbon content, including purging the melt with oxygen, characterized in that, in order to intensify the decarburization process and ensure the carbon content in the melt is not more than 0.015%, during the purging process upon reaching the carbon content of 0.03-0.08% in The melt introduced nickel in the amount of 1.5-2.5% by weight of the melt.
