Изобретение относится к металлургии, к непрерывной разливке металлов. Технический эффект при использовании изобретения заключается в повышении производительности процесса получения непрерывнолитых слитков высокого качества, а также в повышении производительности и эффективности процесса поточного вакуумирования. Указанный технический эффект достигается тем, что подают жидкий металл из разливочного ковша в вакуум-камеру, обрабатывают металл в вакуум-камере, подают металл в промежуточный ковш через патрубок и далее в кристаллизаторы. Металл подают в промежуточный ковш через два патрубка. После подъема уровня металла в промежуточном ковше выше нижних торцов патрубков и герметизации вакуум-камеры жидким металлом в патрубки попеременно периодически подают инертный газ и дополнительно к струйному вакуумированию осуществляют процесс циркуляционного вакуумирования. В процессе вакуумной обработки периодически изменяют направление движения металла в каждом патрубке на противоположное. Изобретение предназначается для применения на установках непрерывной разливки металлов.The invention relates to metallurgy, to the continuous casting of metals. The technical effect when using the invention is to increase the productivity of the process for producing continuously cast ingots of high quality, as well as to increase the productivity and efficiency of the process of continuous evacuation. The indicated technical effect is achieved by supplying liquid metal from a casting ladle to a vacuum chamber, processing the metal in a vacuum chamber, supplying metal to an intermediate ladle through a branch pipe and then to crystallizers. The metal is fed into the intermediate ladle through two nozzles. After raising the level of the metal in the intermediate ladle above the lower ends of the nozzles and sealing the vacuum chamber with liquid metal, inert gas is alternately periodically supplied to the nozzles and, in addition to jet evacuation, a circulating vacuum process is carried out. In the process of vacuum treatment periodically change the direction of movement of the metal in each pipe to the opposite. The invention is intended for use in plants for continuous casting of metals.
