Изобретение относитс  к области черной металлургии и может быть применено при вьшлав.ке конструкцион«ой, нержавеющей, инструментальной и шарикоподшипниковой стали в дуговой электропечи с продувкой металлической ванны кислородсодержащей газовой смесью.The invention relates to the field of ferrous metallurgy and can be applied to the construction of oh, stainless, tool and ball bearing steel in an electric arc furnace with a metal bath blowing oxygen-containing gas mixture.

Известен способ выплавки сталей и сплавов в электропечах, в котором на шлак периодов расплавлени  или окислени  присаживаетс  карбид, кремни  в количестве 1-40 кг/т расплава.There is a known method of smelting steel and alloys in electric furnaces, in which carbide, silicon in the amount of 1–40 kg / t of melt is placed on the slag of periods of melting or oxidation.

Интенсификаци  процесса плавки в периоды расплавлени  и окислени  ванны  вл етс  одним из средств увеличени  производительности плавильного агрегата и уменьшени  угара легирующих элементов.Intensification of the smelting process during the periods of melting and oxidation of the bath is one of the means of increasing the productivity of the smelting unit and reducing the burnout of alloying elements.

Целью изобретени   вл етс  интенсификаци  процесса плавки в период расплавлени  н окислени , a также уменьшение угара легирующих элементов (в частности, хрома, вольфрама, ванади ).The aim of the invention is to intensify the melting process during the period of melting and oxidation, as well as to reduce the loss of alloying elements (in particular, chromium, tungsten, vanadium).

Наиболее целесообразно перед продувкой металлической ванны кислородом иметь в металле расчетное содержание вводимого карбидом кремни  углерода, на 0,2-0,3% (по весу) превышающее верхний предел углерода в данной марке стали.Before blowing a metal bath with oxygen, it is most advisable to have a calculated carbon content of silicon carbide silicon in the metal that is 0.2-0.3% (by weight) higher than the upper limit of carbon in this steel grade.

В случае отсутстви  необходимого количества карбида кремни  последний при выплавке стали по предлагаемому способу может быть частично заменен ферросилицием и углеродом так, чтобы количество вводимого в печь углерода и кремни  оставалось тем же, что и при введении на данную плавку стали одного карбида кремни . 20-50% карбида кремни  замен ют ферросилицием и углеродсодержащими материалами.If there is no required amount of silicon carbide, the latter can be partly replaced by ferrosilicon and carbon when steel is smelted so that the amount of carbon and silicon introduced into the furnace remains the same as when silicon one was added to this steel melting. 20-50% of silicon carbide is replaced by ferrosilicon and carbon-containing materials.
