(54) УСТРОЙСТВО ДЛЯ ВЫСОКОТЕМПЕРАТУРНОЙ ЭКСТРАКЦИИ ГАЗОВ ИЗ МЕТАЛЛОВ И СПЛАВОВ(54) DEVICE FOR HIGH-TEMPERATURE EXTRACTION OF GASES FROM METALS AND ALLOYS
Изобретение относитс к физическому методу анализа веществ, в частности к высокотемпературному анализу материалов на содержание газовых примесей . :The invention relates to a physical method for analyzing substances, in particular, to high-temperature analysis of materials for the content of gas impurities. :
Известно устройство, примен емое при определении газообразующих примесей в металлах и сплавах, состо щее из многовиткового высокочастотного индуктора и водоохлаждаемой кварцевой печи, внутри которой помещен графитовый тигель дл плавлени материала ванны и анализируемых образцов 0.A device used in the determination of gas-forming impurities in metals and alloys is known, consisting of a multi-turn high-frequency inductor and a water-cooled quartz furnace, inside which a graphite crucible is placed to melt the bath material and the samples to be analyzed 0.
Недостатком устройства вл етс взаимодействие материала ванны и образца с графитовым тиглем, что не позвол ет регулировать содержание углерода в расплаве ванны. В качёстве материала ванны в основном примен ют железо, никель или кобальт, в которых раствор етс большое количество углерода (3-5%), что приводит JK загустеванию ванны и образованиюThe drawback of the device is the interaction of the bath material and the sample with a graphite crucible, which does not allow to regulate the carbon content in the bath melt. Iron, nickel or cobalt are mainly used as a bath material, in which a large amount of carbon (3-5%) dissolves, which causes JK to thicken the bath and form
на ее поверхности плотной графитовой корки-спепи. Спаль преп тствует растворению образца в ванне и замедл ет экстракцию из нее газов. Кроме того, графитовый тигель экранирует расплав от высокочастотного и электромагнитного пол , создаваемого индуктором, что затрудн ет перемешивание расплава и снижает скорость вьщелени из него газов. Указанные причины ограничивают применение устройства и лимитируют чувствительность анализа дл многих металлов и сплавов величиной 1 -10 % по массе.on its surface is a dense graphite speck. The bed prevents the sample from dissolving in the bath and slows down the extraction of gases from it. In addition, a graphite crucible shields the melt from the high-frequency and electromagnetic field created by the inductor, which makes it difficult to mix the melt and reduces the rate of gas release from it. These reasons limit the use of the device and limit the sensitivity of the analysis for many metals and alloys to 1-10% by weight.
Наиболее близким к предлагаемому вл етс устройство дл высокотемпературной экстракции газов из металлов и сплавов, состо щее из кварцевой печи и водоохлаждаемого высокочастотного многовалкового индуктора Г2. Closest to the present invention is a device for high-temperature extraction of gases from metals and alloys, consisting of a quartz furnace and a water-cooled high-frequency multi-roll inductor G2.
