Description
Изобретение относитс к черной м&. таллургии и может быть использовано при разливке легированных и высоколегированных сталей дл защиты от вторичного окислени потока жидкого металла между ковшом и центровым литником.This invention relates to a black & m. It can also be used in casting alloyed and high-alloyed steels to protect against the secondary oxidation of the flow of liquid metal between the ladle and the center sprue.
Известно устройство дл защиты струи металла, содержащее корпус и коллектор, имеющий две кольцевые полости, распо ложенные соосно друг над другом, и от- церсти дл выхода газа из верхней полости , расположенные параллельно струе металла, и из нижней полости - под углом к струе металла fl.A device for protecting a metal jet is known, comprising a housing and a manifold having two annular cavities located coaxially one above the other, and holes for the gas to escape from the upper cavity, arranged parallel to the metal jet, and from the lower cavity - at an angle to the metal jet. fl.
Известное техническое решение имеет следующие недостатки: устройство сложно в изготовлении и эксплуатации; уст ройство крепитс к днищу ковша и место креплени не защищаетс нейтральным газом, так как истечение газа предусмот рено только в одном направлении (вниз){ во врем разливки стру металла.полностью закрыта дл визуального наблюдени и невозможно регулировать скорость наполнени изложниц, особенно при раэливке с экзотермическими смес ми, что ухудшает качество слитков{ истечение газа в одном направлении происходит через кольцевые каналы, что приводит к значительному увеличению расхода нейтрального газа.Known technical solution has the following disadvantages: the device is difficult to manufacture and operate; the device is attached to the bottom of the bucket and the place of attachment is not protected by a neutral gas, since the outflow of gas is provided only in one direction (down) {during the pouring the metal stream is completely closed for visual observation and it is impossible to control the filling rate of the molds, especially when melting exothermic mixtures, which degrades the quality of ingots {gas outflow in one direction occurs through annular channels, which leads to a significant increase in the consumption of neutral gas.
Целью изобретени вл етс упрс цени конструкции, уменьшение расхода газа и обеспечение возможности наблюдени и контрол за процессом разливки.The aim of the invention is to control the design, reduce gas consumption and enable observation and control of the casting process.
Дл этого коллектор выполнен в виде двух замкнутых труб, причем отверсти дл выхода в верхней трубе выпол нены в верхней ее части.For this, the collector is made in the form of two closed pipes, with the openings for the outlet in the upper pipe being made in its upper part.
На чертеже изображено описываемое устройство.The drawing shows the described device.
Оно содержит верхнюю 1 н нижнюю 2 замкнутые в виде кольпа трубы дл подвода газа, которые соединены между со бой опорами 3 и зоп рованы от окружающей среды защитным краном 4, трубу 5 дл подвода га.за. Тр лапы 6 дают возможность устанавливать устройство на металлическую воронку 7. Ось отверсти 8 в верхней трубе i расположена парапIt contains the upper 1 n lower 2 gas pipes closed in the form of a colp, which are connected between each other by the supports 3 and protected from the environment by a protective valve 4, the pipe 5 for the supply of gas. Tr paws 6 make it possible to install the device on a metal funnel 7. The axis of the hole 8 in the upper pipe i is parap
