Claims (1)

Способ поточного вакуумирования стали при непрерывной разливке, включающий подачу стали из разливочного ковша в вакуумную камеру, создание в ней необходимого по технологии остаточного давления, обработку стали в вакуум-камере, ее подачу в промежуточный ковш через сливной патрубок, разделение промежуточного ковша поперечными перегородками на среднюю и крайние зоны, подачу стали в среднюю зону промежуточного ковша, раскисление и легирование стали в средней зоне алюминием, подачу на мениск металла промежуточного ковша шлаковой смеси, а также подачу металла из промежуточного ковша в кристаллизаторы и вытягивание из них слитков, отличающийся тем, что в процессе непрерывной разливки положение уровня стали в промежуточном ковше устанавливают ниже уровня слива по желобу и изменяют его по высоте в пределах 0,01 - 0,05 высоты рабочего уровня стали от уровня слива по желобу, при этом расход шлаковой смеси в средней зоне промежуточного ковша устанавливают в пределах 1,2 - 2,5 ее расхода в крайних зонах.A method of continuous steel evacuation of steel during continuous casting, which includes supplying steel from a casting ladle to a vacuum chamber, creating the residual pressure required by the technology, processing the steel in a vacuum chamber, feeding it to the intermediate ladle through a drain pipe, dividing the intermediate ladle with transverse partitions into a middle and extreme zones, the supply of steel to the middle zone of the intermediate ladle, deoxidation and alloying of steel in the middle zone with aluminum, the supply of slag mixture to the meniscus of the intermediate ladle metal, and t Also, the supply of metal from the intermediate ladle to the molds and the extraction of ingots from them, characterized in that in the process of continuous casting, the position of the steel level in the intermediate ladle is set below the drain level in the chute and its height is changed within the range of 0.01 - 0.05 of the working height steel level from the level of discharge through the trough, while the flow rate of the slag mixture in the middle zone of the intermediate ladle is set within 1.2 - 2.5 of its flow rate in the extreme zones.
