Description
Изобретение относитс к металлургии, конкретнее к устройствам дл разливки металла .The invention relates to metallurgy, more specifically to metal casting devices.
Цель изобретени - повышение качества металла за счет увеличени дегазации и снижени содержани неметаллических включений при одновременном сокращении расхода газа.The purpose of the invention is to improve the quality of the metal by increasing degassing and reducing the content of non-metallic inclusions while reducing gas consumption.
На чертеже показано устройство дл газовой обработки струй металла при разливке .The drawing shows a device for the gas treatment of metal jets during casting.
Устройство содержит кольцевой коллектор 1, снабженный газораспределителем 2 и щелевым соплом 3 дл подачи газа Устройство устанавливаетс вокруг стакана 4 с выпускным каналом 5 и уплотн етс в месте примыкани , например, огнеупорным раствором . Стакан 4 закрепл етс в днище разливочного ковша 6. Отношение площадей поперечных сечений щелевого сопла 3 и выпускного канала 5 составл ет 1:(3..,17)The device comprises an annular manifold 1, equipped with a gas distributor 2 and a slot nozzle 3 for gas supply. The device is installed around the cup 4 with the outlet channel 5 and is sealed at the point of abutment, for example, with a refractory solution. The glass 4 is fixed in the bottom of the casting bucket 6. The ratio of the cross-sectional areas of the slit nozzle 3 and the discharge channel 5 is 1: (3 .., 17)
Устройство работает следующим образом .The device works as follows.
При выпуске металла из разливочного ковша 6 через выпускной канал 5 стакана 4 в кольцевой коллектор 1 подают под давлением газ ерез газораспределитель 2. ПослеWith the release of metal from the bottling bucket 6 through the outlet channel 5 of the glass 4 in the annular manifold 1 is supplied under pressure gas through the gas distributor 2. After
заполнени коллектора 1 газ равномерно истекает через щелевое сопло 3 в виде кольцевого потока вокруг струи металла и обеспечивает возможность обработки струи металла и ее защиту от вторичного окислени ,filling the collector 1, the gas uniformly flows through the slit nozzle 3 in the form of an annular flow around the metal jet and allows the metal jet to be treated and protected from secondary oxidation,
В качестве газа используетс агрон и другие газы.Agron and other gases are used as gas.
Использование устройства позвол ет повысить качество металла за счет снижени оксидных включений, водорода и азота, а также за счет сокращени дефектов по трещинам и рванинам.The use of the device allows to improve the quality of the metal by reducing oxide inclusions, hydrogen and nitrogen, as well as by reducing defects in cracks and flaws.
