Изобретение относитс к внепечной обработке жидкого металла.The invention relates to the secondary treatment of a liquid metal.
По основному авт.св. № 178843 известен способ вакуумировани жидких металлов с одновременной обработкой в столбе жидкого шлака.According to the main auth. No. 178843, a method of evacuating liquid metals with simultaneous treatment of a liquid slag in a column is known.
Однако рафинирование металла по указанному способу не проходит достаточно полно вследствие ухудшени рафинирующих свойств шлака в течение процесса из-за обогащени его окислами железа , марганца и кремни , а при окислительном процессе реакци обезуглероживани не получает должного развити .However, the refining of the metal by this method is not sufficiently complete due to the deterioration of the refining properties of the slag during the process due to its enrichment with oxides of iron, manganese and silicon, and during the oxidative process the decarburization reaction does not develop properly.
Предлагаемый способ внепечного рафинировани жидкого металла позвол ет поддерживать высокую рафинирукхцую способность шлака в течение всего процесса путем вдувани в столб шлака активного газа окислител или восстановител или порошкообразных добавок,The proposed method of secondary refining of liquid metal allows maintaining the high refining capacity of the slag during the whole process by injecting the active gas of an oxidizing agent or reductant or powdered additives into the slag column.
При создании разрежени в вакуумной камере в шлаковый рукав , сообщающийс с камерой, поступает необходимое количество шлака за счет разности барометрического и остаточного давлени .When a vacuum is created in the vacuum chamber, the required amount of slag is supplied to the slag sleeve in communication with the chamber due to the difference in barometric and residual pressure.
Затем в вакуумную камеру из копильника подают жидкий металл, который , проход через столб шлака в оукаве, рафинируетс .Then a liquid metal is supplied to the vacuum chamber from the digger, which, through the slag column in the oakawa, is refined.
Перед подачей металла в камеру или в процессе его обработки в столб шлака через фурмы вдувают ; активный газ, окислитель или BOGS становитель в зависимости от характера процесса.Before the metal is fed into the chamber or during its processing, slag is blown into the slag column through the tuyeres; active gas, oxidizer or BOGS mill, depending on the nature of the process.
Вместо газа можно также вдувать твердые добавки в виде порошка с помощью инертного или активного газа.Instead of gas, solid additives can also be blown in the form of a powder with an inert or active gas.
