Изобретение относитс к металлургии, а именно к разливке металлов и сплавов на установках непрерывной разливки, и быть использовано на металлургических ii мап1иностроитсльных заводах.The invention relates to metallurgy, in particular to the casting of metals and alloys in continuous casting plants, and to be used in metallurgy and machine building plants.
Известен способ разливки с подачей стали через два или более огнеупорных стакана, причем обща площадь проходных сечений обоих стаканов выбираетс из расчета обеспечени полной весовой скорости лить с возможным ее -превышением до 20%.There is a known method of casting with steel feed through two or more refractory glasses, and the total area of the flow areas of both glasses is chosen on the basis of ensuring the full casting weight rate with its possible increase to 20%.
Использование этого способа дл разливки стали, раскисленной повышенным количеством алюмини , приводит к зат гиванию стаканов и вынуждает прожигать их каналы кислородом . Резкие изменени скорости разливки , обусловленные указанным фактором, вл ютс причиной неудовлетворительного в р де случаев качества слитков.Using this method for casting steel deoxidized with an increased amount of aluminum results in tightening of the glasses and forcing them to burn their channels with oxygen. Abrupt changes in casting speed due to this factor are the reason for the poor quality of the ingots in a number of cases.
Иредлагаемый способ позвол ет повысить качество слитков путем обеспечени посто нного расхода металла (сплава). Дл этого в днище промежуточного ковша устанавливают два стакана, каждый из которых обеспечивает полную весовую скорость лить . Вначале металл (сплав) подают через один стакан. С началом зат гивани его канала подают металл (сплав) через второй стакан, постепенно увеличива расход по мере развити зат гивани первого стакана. Компенсаци уменьшеки расхода reтaллa (сплава) через первый стакан увеличением подачи через второй стакан позвол ет поддерживать посто нную скорость разливки.The proposed method allows to improve the quality of ingots by ensuring a constant consumption of metal (alloy). To do this, two glasses are placed in the bottom of the tundish, each of which provides full weight for pouring. Initially, the metal (alloy) is fed through one glass. With the beginning of the indentation of its channel, the metal (alloy) is fed through the second glass, gradually increasing the flow rate as the pressure of the first glass develops. Compensation by reducing the consumption of retalla (alloy) through the first cup by increasing the feed through the second cup allows maintaining a constant casting speed.
При существенном зат гивании канала стаканов металл (сплав) может подаватьс через один из стаканов, причем второй стакан в это врем прожигаетс кислородом. Поочередное восстановление размеров каналов разливочных стаканов позволит осуществить посто нный расход металла (сплава) через из стаканов.With a significant tightening of the canal of the glasses, the metal (alloy) can be supplied through one of the glasses, with the second glass being burned with oxygen at this time. Alternately restoring the dimensions of the channels of the casting glasses will allow a constant consumption of metal (alloy) through the glasses.
Использование предлагаемого способа позволит получить качественную поверхность непрерывных слитков за счет исключени резких из reнeний скорости разливки.The use of the proposed method will allow to obtain a high-quality surface of continuous ingots by eliminating abrupt casting speeds.

Предмет изобретени Subject invention
Сиособ непрерывной разливки металлов и сплавов через два или более сливных стакана с восстановлением размеров каналов стаканов в процессе разливки, отличающийс тем, что. с целью повышени качества слитков, металл разливают поочередно через один и два стакана, при этом один из них работает в режиме торможени .The method of continuous casting of metals and alloys through two or more drain glasses with the restoration of the size of the channels of the glasses during the casting process, characterized in that. in order to improve the quality of the ingots, the metal is poured alternately through one and two glasses, while one of them operates in the braking mode.
