(54) СПОСОБ ВЫПЛАВКИ СТАЛИ(54) STEEL MELTING METHOD

Изобретение отаоситс  к технологии выплавки сталей и может осуществл тьс  на всех предпри ти х, производ щих выплавку стали в электродуговых печах дл  фасонного лить  и заготовок дл  поковок различного назначени .The invention is based on the technology of steel smelting and can be carried out at all enterprises producing steel smelting in electric arc furnaces for shaped casting and blanks for forgings of various purposes.

Существуют несколько способов выплавки стали.There are several ways to smelt steel.

На некоторых заводах при плавке стали после окислительного периода удал ют из печи вО-8О% шлака и навод т новый шлак путем загрузки в печь 1-2% (от веса металла ) смеси кварцевого песка и шамотного бо  и 0,5 - 1,0 % известн ка.In some factories, during the smelting of steel after the oxidation period, slag of OO-8O% slag is removed from the furnace and new slag is introduced into the furnace by loading 1-2% (by weight of metal) of a mixture of quartz sand and chamotte bo and 0.5-1.0 % limestone

После расплавлени  шлакообразующих и образовани  в печи монокелезистого шлака металл раскисл ют ферросилицием или си- ликомарганцем и другими легкоокисл5пощимис  элементами, вход щими в состав стали .After melting of the slag-forming and formation of a mono-iron slag in the furnace, the metal is deoxidized with ferrosilicon or silicon manganese and other easily acidified metals with the elements that make up the steel.

Иногда плавку дл  фасонного лить  ведут с диффузионным раскислением. После того как содержание углерода в металле в процессе окислени  достигнет нижнего предела , определ емого маркой стали, скачивают 60-80% шлака и в печь ввод т около О, 5 % ферромарганца или снликомарганца, 0,5 - 1.О % известн ка и 1-2% шамотносго бо  или кварцевого песка, После расплавлени  шлакообразующих раскисл ют шлак молотым коксом и фeppocилициe I. Затем в металл ввод т кремний и марганец.Sometimes melting for shaped casting is carried out with diffusion deoxidation. After the carbon content in the metal during the oxidation process reaches the lower limit determined by the steel grade, 60-80% of the slag is loaded and about 0%, 5% ferromanganese or carbon manganese, 0.5-1.0% limestone and 1-2% of fireclay or quartz sand. After the slag-forming sand is melted, slag is deoxidized with ground coke and compression I. Then silicon and manganese are introduced into the metal.

Известен способ выплавки сталей дл  фасонного лить  с предварительным раскислением металла в начале восстановительного периода доменным ферромарг анцем в количестве 0,5 % или силикомарганцем с окончательным раскислением металла алюминием 1.There is a known method of smelting steels for shaped casting with preliminary metal deoxidation at the beginning of the recovery period by blast furnace ferromark in the amount of 0.5% or silicomanganese with final metal deoxidation with aluminum 1.

Недостатки известного способа следующие:The disadvantages of this method are the following:

а)большой угар и безвозвратньге потери марганца со шлаком;a) large waste and irretrievable loss of manganese with slag;

б)увеличение продолжительности плавки из-за необходимости повторной корректировки химического состава стали по марганцу перед выпуском металла из печи;b) an increase in the duration of smelting due to the need to re-adjust the chemical composition of the steel for manganese before the metal is released from the furnace;

в)повышенна  загр зненность выплавлен.ного металла фосфором и неметаллическимтвключени ми;c) increased contamination of the molten metal with phosphorus and non-metallic inclusions;
