Изобретение может быть использовано в черной металлургии при разливке стали с использованием поточного или струйного вакуумирования. Использование такого способа позволяет повысить степень дегазации и улучшить качество разливаемой стали. Цель изобретения - создание развитой межфазной поверхности газ-металл за счет ввода в струю металла перед вакуумированием достаточного количества инертного газа и увеличение степени дегазации металла. Отличие предлагаемого способа состоит в том, что инертный газ вводится через шиберный затвор в струю металла, протекающего через сталеразливочный канал, посредством кольцевой пористой огнеупорной вставки. При этом пористость вставки составляет 20-40%, средний радиус сквозных пор 0,03-0,05 мм. Расход инертного газа 0,05-0,08 нм3/т стали.The invention can be used in ferrous metallurgy in the casting of steel using continuous or jet pumping. Using this method allows to increase the degree of degassing and improve the quality of cast steel. The purpose of the invention is the creation of a developed gas-metal interface by introducing a sufficient amount of inert gas into the metal stream before evacuation and increasing the degree of metal degassing. The difference of the proposed method is that an inert gas is introduced through the slide gate into the stream of metal flowing through the steel pouring channel through an annular porous refractory insert. Moreover, the insert porosity is 20-40%, the average radius of the through pores is 0.03-0.05 mm. The inert gas flow rate is 0.05-0.08 nm3 / t of steel.
