Claims (3)

1. Способ производства непрерывнолитых заготовок из нержавеющей стали с титаном, включающий выплавку в сталеплавильном агрегате, внепечную обработку, легирование титаном, вакуумирование, непрерывную разливку стали на МНЛЗ, отличающийся тем, что титан вводят в жидкую сталь перед операцией вакуумирования при массе шлака в ковше в пределах 1-7 кг/т стали из расчета получения содержания титана в пределах (5-8)*С, где С - фактическое содержание углерода, вакуумирование проводят при остаточном давлении менее 5 мбар в течение 15-30 мин, в процессе разливки осуществляют электромагнитное перемешивание металла в кристаллизаторе.1. A method for the production of continuously cast billets of stainless steel with titanium, including smelting in a steel-smelting unit, out-of-furnace processing, alloying with titanium, vacuuming, continuous casting of steel on a CCM, characterized in that titanium is introduced into liquid steel before the vacuuming operation with a mass of slag in the ladle in within 1-7 kg / t of steel based on obtaining the titanium content in the range of (5-8) * C, where C is the actual carbon content, evacuation is carried out at a residual pressure of less than 5 mbar for 15-30 minutes, electromagnetic metal mixing in the mold. 2. Способ по п. 1, отличающийся тем, что электромагнитное перемешивание металла в кристаллизаторе проводят непрерывно в одну сторону с силой тока 100-300 А и частотой 2,5-3,5 Гц.2. The method according to p. 1, characterized in that the electromagnetic stirring of the metal in the mold is carried out continuously in one direction with a current strength of 100-300 A and a frequency of 2.5-3.5 Hz. 3. Способ по п. 1, отличающийся тем, что электромагнитное перемешивание металла в кристаллизаторе проводят реверсивно, а именно: 5-15 секунд вращение электромагнитного поля по часовой стрелке, 1-4 секунды пауза, 5-15 секунд вращение против часовой стрелки, с силой тока 140-350 А и частотой 2,5-3,5 Гц.3. The method according to p. 1, characterized in that the electromagnetic stirring of the metal in the mold is carried out in reverse, namely: 5-15 seconds rotation of the electromagnetic field clockwise, 1-4 seconds pause, 5-15 seconds counterclockwise rotation, with current strength 140-350 A and frequency 2.5-3.5 Hz.
