(54) СПОСОБ ВШЛАВКИ СТАЛИ(54) METHOD OF STEEL AHEAD
:. Иэофетение относитс к черной ме- талиургии, конкретнее - к способам Bbtплавки стали в кислородаых конвертерах.:. Bezofethenia refers to ferrous metallurgy, more specifically, to Bbt methods of steel melting in oxygen converters.
Известен способ производства стали, при котором в конвертер поверх загруженных чушкового чугуна и стального )вдма располагают кокс в количестве 0,5-1,75% от веса металлошнхтьи Затем кокс зажигают с помощью газовой горелви и начинают продувку кислородом. С началом расплавлени шихты увеличивают расход кислорода. Шлакообразуюшве и легирующие ввод т в процессе плавки об1, пор дком l 1 There is a known method of steel production, in which coke in an amount of 0.5-1.75% by weight of metal cloth is placed in a converter on top of loaded pig iron and steel iron) Then coke is ignited with a gas burner and an oxygen purge is started. With the beginning of the melting of the charge increase the consumption of oxygen. Slag-forming and alloying materials are introduced during the smelting process, in the order of l 1
Недостатками данного способа выплавки стали вл ютс неэкономичность процесса , заключающа с в том что необходимы большие затраты энергии на расплавление чугуна и лома, низка стойкость футеровки, значительный угар металла и высокий расход шлакообразующих .The disadvantages of this method of steel smelting are the inefficiency of the process, which means that large energy costs are needed to melt pig iron and scrap, low lining durability, significant waste of metal and high slag-forming consumption.
Наиболее близким к изобретению вл етс способ выплавки стали в кислородном конвертере, включающий завалку металлического лома и извести, ввод в : конвертер углеродсодержащих материалов, заливку жидкого чугуна н продувку металла кислородом 2 J .The closest to the invention is a method of smelting steel in an oxygen converter, which includes the filling of metal scrap and lime, entering into: a converter of carbon-containing materials, pouring liquid iron and metal purging with oxygen 2 J.
Недостатком этого способа вл етс то, что в качестве углеродсодержашего материала применен антрацит, который содержит значительное количество серы The disadvantage of this method is that anthracite, which contains a significant amount of sulfur, is used as a carbon-containing material.
10 ; (О,7-2,0%), поэтому этот способ выплав1Ш неприемлем при производстве стали ответственного назначени . Кроме того, в начальной стадии продувки нерастворившиес куски антрацита замедл ют формиts рование активного шлака, так как кислород дуть расходуетс в основном на окисление углерода антради-га. Вследствие этого содержание окислов железа в первичном шлаке невелико, что отрицательно ten ; (O, 7-2.0%), therefore this method of smelting is unacceptable in the production of steel of responsible purpose. In addition, in the initial stage of flushing, undissolved chunks of anthracite slow down the formation of active slag, since oxygen blowing is mainly used to oxidize anthrax carbon. As a result, the content of iron oxides in the primary slag is small, which is negative
20 сказываетс на растворении извести.20 affects the dissolution of lime.
Цель изобретени - снижение содержани серы в готовой стали, наведение активных шлаков в начальный период проThe purpose of the invention is to reduce the sulfur content in the finished steel, targeting the active slags in the initial period
