Изобретение относитс к черной металлургии .This invention relates to the steel industry.
Известно устройство дл отбора пробы жидкого металла, содержащее металлическую пробницу, в днище которой встроена кварцева трубка с металлическим кристаллизатором .A device for sampling a liquid metal containing a metal probe, in the bottom of which a quartz tube with a metal crystallizer is embedded, is known.
Целью изобретени вл етс повышение надежности отбора пробы в кварцевую трубку и улучшение плотности лробы.The aim of the invention is to increase the reliability of sampling a quartz tube and improve the density of the tomb.
Дл этого устройство снабжено патрубком, одни конец которого сообщаетс с атмосферой , а другой - с полостью кварцевой трубки через продольные каналы, выполненные на боковой поверхности кристаллизатора.For this, the device is provided with a nozzle, one end of which communicates with the atmosphere, and the other end with the cavity of the quartz tube through longitudinal channels formed on the lateral surface of the crystallizer.
Иа чертеже изображено предлагаемое устройство .The drawing shows the proposed device.
Оно имеет металлическую пробницу 1, наружна поверхность которой может защищ .атьс от воздействи жидкого расплава асбестом или картоном. Дл предотвращени попадани шлака в пробницу при вз тии пробы она закрываетс тонкой металлической прокладкой 2.It has a metal test probe 1, the outer surface of which can be protected from exposure to liquid melt with asbestos or cardboard. To prevent slag from entering the test probe when sampling, it is covered with a thin metal gasket 2.
Пробница имеет смесительную камеру 3, выполненную в виде усеченного конуса, и цилиндрическую камеру 4. В днище пробницы встроена кварцева трубка 5 с кристаллизатором 6, имеющим продольные каналы а. К пробнице приварен патрубок 7, один конец которого сообщаетс с атмосферой, а другой - с полостью кварцевой трубки 5 через каналы а кристаллизатора 6. Сквозное отверстие б закрываетс асбестом 8 и служит дл облегчени удалени пробы из пробницы.The test probe has a mixing chamber 3, made in the form of a truncated cone, and a cylindrical chamber 4. A quartz tube 5 with a mold 6 having longitudinal channels a is embedded in the bottom of the test probe a. A test tube 7 is welded to the test probe, one end of which communicates with the atmosphere and the other with the cavity of the quartz tube 5 through the channels of the crystallizer 6. The through hole b is closed with asbestos 8 and serves to facilitate removal of the sample from the test probe.
Отбор пробы осуществл ют следующим образом .The sampling is carried out as follows.
Пробница погружаетс в металл. После плавлени прокладки 2 металл затекает в камеры 3 и 4, а также в кварцевую трубку 5. Благодар кристаллизатору 6 металл очень быстро кристаллизуетс , а газы вытесн ютс через трубку 5, каналы а и патрубок 7 в атмосферу . После удалени пробы из пробницы цилиндрическую ее часть отрезают дл химического или спектрального анализа, а часть пробы, полученную в кварцевой трубке, - дл анализа на кислород.The probe is immersed in metal. After the gasket 2 is melted, the metal flows into the chambers 3 and 4, as well as into the quartz tube 5. Thanks to the crystallizer 6, the metal crystallizes very quickly, and the gases are forced out through the tube 5, channels a and the nozzle 7 into the atmosphere. After removing the sample from the test tube, its cylindrical part is cut for chemical or spectral analysis, and a part of the sample obtained in the quartz tube is cut for oxygen analysis.
