Claims (5)

1. Способ легирования стали марганцем, включающий выплавку, раскисление, легирование, введение в жидкий металл оксидов марганца и кальция, получение жидкого металла, содержащего восстановители и обработку жидкого металла в ковше, отличающийся тем, что после раскисления стали и выпуска шлака, на зеркало металла задают смесь, содержащую оксиды марганца с восстановителем в количестве 40-60% от необходимого, а остальную ее часть задают вместе с известью в процессе выпуска металла в ковш.1. The method of alloying steel with manganese, including smelting, deoxidation, alloying, the introduction of liquid metal oxides of manganese and calcium, obtaining a liquid metal containing reducing agents and processing liquid metal in a ladle, characterized in that after the deoxidation of steel and the release of slag on a metal mirror set the mixture containing manganese oxides with a reducing agent in an amount of 40-60% of the required, and the rest of it is set together with lime during the release of metal into the ladle. 2. Способ по п.1, отличающийся тем, что в качестве восстановителей используют металлы, термодинамическая прочность оксидов которых выше, чем у закиси марганца.2. The method according to claim 1, characterized in that metals are used as reducing agents, the thermodynamic strength of the oxides of which is higher than that of manganese oxide. 3. Способ по п.1, отличающийся тем, что содержание кремния в стали перед выпуском в ковш поддерживают на 20-30% выше его верхнего предела для данной марки стали.3. The method according to claim 1, characterized in that the silicon content in the steel before being released into the ladle is maintained 20-30% higher than its upper limit for a given steel grade. 4. Способ по п.1, отличающийся тем, что в качестве марганца используют его соединения с кислородом при содержании в них марганца от 62,2 до 72,0%.4. The method according to claim 1, characterized in that as manganese use its compounds with oxygen with a manganese content of from 62.2 to 72.0%. 5. Способ по п.1, отличающийся тем, что после выпуска металла его продувают инертным газом в течение 3-5 мин.5. The method according to claim 1, characterized in that after the release of the metal it is purged with an inert gas for 3-5 minutes.
