Claims (5)

1. Способ получения стали (1) с высоким содержанием марганца и низким содержанием углерода из жидкого чугуна (2) или жидкой стали (3) и шлакообразующих, отличающийся тем, что осуществляют подачи жидкого ферромарганца (5) с содержанием углерода примерно 6% и жидкой стали (3, 3а) с содержанием углерода примерно 0,1% или жидкого чугуна в конвертер (6а) для рафинирования ферромарганца вместе с необходимым количеством шлакообразующих (4), при этом посредством комбинированной продувки кислородом (7) через верхние (8) и нижние (9) фурмы содержание углерода в расплаве снижают примерно до 0,7-0,8%, причем некоторое количество холодного продукта предыдущей плавки используют в качестве охладителя (10), и при этом путем непрерывной продувки кислородом (7) через нижние фурмы (9) содержание углерода снижают примерно до 0,05-0,1%.1. The method of producing steel (1) with a high content of manganese and low carbon from molten iron (2) or liquid steel (3) and slag-forming, characterized in that the supply of liquid ferromanganese (5) with a carbon content of about 6% and liquid steel (3, 3a) with a carbon content of about 0.1% or molten iron into a converter (6a) for refining ferromanganese together with the required amount of slag-forming materials (4), while using a combined oxygen purge (7) through the upper (8) and lower (9) tuyeres carbon content in the melt is reduced to about 0.7-0.8%, and a certain amount of the cold product of the previous melt is used as a cooler (10), and by continuously purging with oxygen (7) through the lower tuyeres (9), the carbon content is reduced to about 0 , 05-0.1%. 2. Способ по п.1, отличающийся тем, что обеспечивают снижение парциального давления при комбинированной продувке кислородом (7) и смесью (11) кислорода и инертного газа через верхнюю (8) и нижние (9) фурмы.2. The method according to claim 1, characterized in that they provide partial pressure reduction during combined purging with oxygen (7) and a mixture (11) of oxygen and inert gas through the upper (8) and lower (9) tuyeres. 3. Способ по п.1 или 2, отличающийся тем, что все этапы способа осуществляют в интервале температура от 1630 до 1650°С.3. The method according to claim 1 or 2, characterized in that all the steps of the method are carried out in the temperature range from 1630 to 1650 ° C. 4. Способ по п.1 или 2, отличающийся тем, что для получения конечного анализа осуществляют подачу силикомарганца и/или ферроалюминия в расплав (13) на печи-ковше (12).4. The method according to claim 1 or 2, characterized in that in order to obtain the final analysis, silicomanganese and / or ferroaluminium is fed into the melt (13) on a ladle furnace (12). 5. Плавильная установка для получения стали (1) с высоким содержанием марганца и низким содержанием углерода, в которой предусмотрена подача (14) чугуна или углеродистой стали, а также шлакообразующих (4) и сопутствующих элементов (15), отличающаяся тем, что перед конвертером (6а) для рафинировании ферромарганца предусмотрена восстановительная печь (16) для ферромарганца и с другой стороны шахтная печь (17) для получения чугуна (2) или кислородный конвертер (6) для получения углеродистой стали (3а) или электропечь (18), а после конвертера (6а) для рафинирования ферромарганца предусмотрена печь-ковш (12).5. A smelting plant for producing steel (1) with a high content of manganese and low carbon content, which provides for the supply (14) of cast iron or carbon steel, as well as slag-forming (4) and related elements (15), characterized in that in front of the converter (6a) for refining ferromanganese, a reduction furnace (16) for ferromanganese is provided and, on the other hand, a shaft furnace (17) for producing cast iron (2) or an oxygen converter (6) for producing carbon steel (3a) or an electric furnace (18), and after converter (6a) for refiner Bani ferromanganese provided ladle furnace (12).
