Изобретение касаетс вакуумной обработкр жидкого металла.The invention relates to the vacuum treatment of liquid metal.
Известен способ вакуумной обработки жидкого металла с одновременной нродувкой его инертным газом.There is a method of vacuum processing of a liquid metal with simultaneous extraction with an inert gas.
По предлагаемому способу инертный газ, например аргон, которым продувают жидкую сталь нли сплавы в вакууме, предварительно пропускают через емкость с расплавом щелочных , щелочноземельных металлов (например , литием) и их смесей. Это позвол ет, вопервых , очистить инертный газ от кислорода, азота и других газов, всегда присутствующих в нем и снижающих эффект очистки стали при нродувке, и, во-вторых, обеснечнть насыщение инертного газа парами щелочных, щелочноземельных металлов и их смесей.According to the proposed method, an inert gas, for example argon, with which liquid steel is blown or alloys in vacuum, is preliminarily passed through a container with a melt of alkali, alkaline earth metals (for example, lithium) and their mixtures. This makes it possible, first, to purify the inert gas from oxygen, nitrogen and other gases that are always present in it and reduce the effect of cleaning steel during the afterburning, and, secondly, to saturate the inert gas with alkali, alkaline earth metal vapors and their mixtures.
Понада вместе с инертным газом в жидкую сталь или сплавы, пары взаимодействуют с растворенными кислородом, водородом, азотом , серой, фосфором, мышь ком, неметаллическими включени ми и др. Продукты реакции в подавл ющем большинстве газообразны , поэтому легко и полно удал ютс из жидкой стали в вакууме. Термодинамические и кинетические услови , возникающие при продувке стали в вакууме инертными газами, насын,енными парами щелочных, щелочноземельных металлов и их смесей, позвол ют получить сталь с нрактическн незначительнымPonad together with inert gas into molten steel or alloys, vapors interact with dissolved oxygen, hydrogen, nitrogen, sulfur, phosphorus, mice, nonmetallic inclusions, etc. Most of the reaction products are gaseous and therefore easily and completely removed from the liquid steel in a vacuum. The thermodynamic and kinetic conditions that occur when a steel is blown in vacuum with inert gases, saturated gases, alkali metal, alkaline earth metals, and their mixtures make it possible to produce steel with a practically insignificant

Жидкую сталь 1 (см. чертеж), наход щуюс в ковще 2 или другом резервуаре под вакуумом , продувают инертным газом, например , нри помощи устройства 3. Предварительно инертный газ попадает в емкость 4 с расплавом щелочных, щелочноземельных металлов н нх смесей.Liquid steel 1 (see drawing), located in bucket 2 or another tank under vacuum, is flushed with an inert gas, for example, using device 3. Pre-inert gas flows into tank 4 with a melt of alkaline, alkaline earth metals and nn mixtures.
В завнсимости от различного содержани вредных нримесей и газов в жидкой стали необходимо различное колнчество наров щелочных , щелочноземельных металлов в ннертномDepending on the different content of harmful impurities and gases in the liquid steel, a different quantity of alkali, alkaline earth metals in organic matter is necessary.
газе, которое онредел етс темнературой расплава . Температуру раснлава Н1,елочных, Н1,елочноземельных металлов н их смесей в емкости можно измен ть вертикальным перемещением емкости относительно зеркала обрабатываемой жидкой стали нли сплавов, излучающих тепло и нагревающих емкость.gas, which is determined by the melt temperature. The temperature of the rasklava H1, fir-tree, H1, earth-metal metals and their mixtures in the tank can be changed by vertical movement of the tank relative to the mirror of the treated liquid steel or alloys that emit heat and heat the tank.
При этом обеснечнваетс регулированне количества наров щелочных металлов в инертном газе в зависимости от заглублени фурмы , т. е. от объема обрабатываемой жидкой стали. Чем больше заглубление фурмы в жидкую сталь, тем ближе емкость с раснлавом щелочных металлов к зеркалу стали, выше его темнература и больше количество наров,In this case, regulation of the amount of alkali metal alkali in an inert gas is impaired depending on the depth of the tuyere, i.e., on the volume of liquid steel being treated. The greater the depth of the tuyere into the liquid steel, the closer the container with alkaline metal melting to the steel mirror, the higher its temperature and the greater the number of bunks,
и наоборот.and vice versa.
