Abstract

1. Способ получения литой полосы из низкоуглеродистой, частично раскисленной Mn/Si стали, в котором стальной расплав подают из разливочной ванны между по меньшей мере двумя движущимися вместе со стальной полосой охлаждаемыми литейными валками, при этом сталь на литейных валках по меньшей мере частично отверждается для образования стальной полосы, отличающийся тем, что стальной расплав имеет содержание серы от 20 до 300 ppm и соотношение Mn/Si≥3,5, при этом в нормальном режиме работы усилие формования полосы составляет от 2 до 50 кН/м. ! 2. Способ по п.1, отличающийся тем, что стальной расплав имеет содержание серы от 50 до 250 ppm, предпочтительно от 70 до 200 ppm. ! 3. Способ по любому из пп.1 и 2, отличающийся тем, что усилие формования полосы составляет от 5 до 30 кН/м. ! 4. Способ по любому из пп.1-3, отличающийся тем, что стальной расплав содержит неметаллические включения с массовой долей Al2O3 менее 45 вес.%. ! 5. Способ по п.3, отличающийся тем, что стальной расплав содержит неметаллические включения с массовой долей Al2O3 менее 45 вес.%. 1. A method for producing a cast strip of low-carbon, partially deoxidized Mn / Si steel, in which a steel melt is supplied from a casting bath between at least two cooled casting rolls moving together with a steel strip, the steel on casting rolls being at least partially cured for the formation of a steel strip, characterized in that the steel melt has a sulfur content of from 20 to 300 ppm and a ratio of Mn / Si≥3.5, while in normal operation, the molding force of the strip is from 2 to 50 kN / m ! 2. The method according to claim 1, characterized in that the steel melt has a sulfur content of from 50 to 250 ppm, preferably from 70 to 200 ppm. ! 3. The method according to any one of claims 1 and 2, characterized in that the strip forming force is from 5 to 30 kN / m. ! 4. The method according to any one of claims 1 to 3, characterized in that the steel melt contains non-metallic inclusions with a mass fraction of Al2O3 of less than 45 wt.%. ! 5. The method according to claim 3, characterized in that the steel melt contains non-metallic inclusions with a mass fraction of Al2O3 of less than 45 wt.%.
