Abstract

FIELD: metallurgy, namely metal continuous casting. SUBSTANCE: method comprises steps of feeding melt metal from casting ladle to vacuum chamber, creating residual pressure into it, treating metal in vacuum chamber, feeding metal to intermediate ladle through branch pipe under level of metal in it, filling intermediate ladle by metal until working level, feeding metal to molds and then drawing ingots out of them. Before starting continuous casting process branch pipe and intermediate ladle are being moved one to another in order to set gap value between lower end of branch pipe and bottom of intermediate ladle equal to 0.01-0.2 of height of working level of metal in intermediate ladle. Then intermediate ladle is being filled by metal through branch pipe until working level. After metal level becomes higher than lower end of branch pipe that branch pipe and intermediate ladle are being moved in reverse direction by distance corresponding to depth of branch pipe immersion under metal level equal to 0.1 - 0.4 of metal working level in intermediate ladle. EFFECT: enhanced efficiency, high quality of ingots.

Изобретение относится к металлургии, конкретнее к непрерывной разливке металлов. Технический эффект при использовании изобретения заключается в повышении производительности непрерывной разливки вакуумированного металла и улучшении качества непрерывнолитых слитков. Указанный технический эффект достигается тем, что подают жидкий металл из разливочного ковша в вакуумкамеру, создают в ней остаточное давление, обрабатывают металл в вакуумкамере, подают металл в промежуточный ковш через патрубок под уровень металла в нем, наполняют промежуточный ковш металлом до рабочего уровня, подают металл в кристаллизаторы, а также вытягивают из них слитки. Перед началом процесса непрерывной разливки производят относительное перемещение патрубка и промежуточного ковша навстречу друг к другу и устанавливают величину зазора между нижним торцом патрубка и днищем промежуточного ковша, равной 0,01-0,2 высоты рабочего уровня металла в промежуточном ковше. После этого начинают производить наполнение промежуточного ковша металлом через патрубок до рабочего уровня, а после подъема уровня металла выше нижнего торца патрубка производят обратное относительное перемещение патрубка и промежуточного ковша на расстояние, соответствующее глубине погружения патрубка под уровень металла, равной 0,1-0,4 величины рабочего уровня металла в промежуточном ковше. Изобретение предназначено для применения на установках непрерывной разливки металлов.The invention relates to metallurgy, and more particularly to continuous casting of metals. The technical effect when using the invention is to increase the performance of continuous casting of evacuated metal and improve the quality of continuously cast ingots. The indicated technical effect is achieved by supplying liquid metal from the pouring ladle to the vacuum chamber, creating residual pressure in it, processing the metal in the vacuum chamber, feeding the metal into the intermediate ladle through a nozzle below the metal level in it, filling the intermediate ladle with metal to the working level, supplying metal into molds, and also draw ingots from them. Before starting the continuous casting process, the nozzle and the intermediate ladle are moved relative to each other and the gap between the lower end of the nozzle and the bottom of the intermediate ladle is set equal to 0.01-0.2 of the working level of the metal in the intermediate ladle. After that, the intermediate ladle is filled with metal through the nozzle to the working level, and after the metal level rises above the lower end of the nozzle, the relative relative displacement of the nozzle and the intermediate ladle to a distance corresponding to the depth of immersion of the nozzle under the metal level equal to 0.1-0.4 the working level of the metal in the tundish. The invention is intended for use in plants for continuous casting of metals.
