Description

Предлагаемый способ спектрального анализа распотащленного металла заключаетс  в том, что дл  исключени  эффекта обискривани . вли ни  структуры и неоднородности снлава, а также дл  сокращени  продолжительности анализа; электрический разр д (искру или дугу) образуют между струей расплавленного металла vr посто нным электродом.The proposed method for the spectral analysis of expanded metal is to eliminate the effect of curving. influence of the structure and heterogeneity of the fusion, as well as to reduce the duration of the analysis; an electric discharge (spark or arc) is formed between a stream of molten metal vr by a constant electrode.

Струю р С1 лавленно1:о металла получают при номощи ирибора (струеобразовател ). схема которого нриведеиа на чертеже.The jet of p C1 lavlenno1: o metal is obtained by nomoshki iribor (stream-forming agent). scheme which nrivedeya on the drawing.

В электрической тигельной нечи 1, укрепленной на станине 2, находитс  чугунна  воронка 3, отверстие которой выходит из печн )1аружу.In the electric crucible bed 1, mounted on the bed 2, there is a cast iron funnel 3, the hole of which goes out of the furnace.

Воронка 3 соединена с одним из выводов источника тока (нанример, искровозбудител ). Второй вывод, источника тока соединен с иосто нньпт электродом 4, вложенным в цангу 5.The funnel 3 is connected to one of the terminals of the current source (nanometer, spark exciter). The second output of the current source is connected to an iosto nnpt electrode 4 inserted into the collet 5.

Материалом дл  посто нного электрода 4 служит проволока диаметром 3,5 мм из чистого основного металла анализируемого сплава (чистый алюминий в случае анализа алюминиевых сплавов, электролитическа  медь в случае анализа бронз и т. п.).The material for the permanent electrode 4 is 3.5 mm wire of pure base metal of the analyzed alloy (pure aluminum in the case of analysis of aluminum alloys, electrolytic copper in the case of analysis of bronze, etc.).

Посто нный электрод 4 устанавливаетс  на оси коллиматора спектрографа на матрице 6 до соприкосновени  с ее площадкой, после чего матрица 6 выдвигаетс . Ограничитель 7 служит дл  установки матрицы 6.A constant electrode 4 is mounted on the axis of the collimator of the spectrograph on the matrix 6 until it is in contact with its platform, after which the matrix 6 advances. The limiter 7 serves to set the matrix 6.

Работа на нриборе осуществл етс  следующим образом.Work on the instrument is carried out as follows.

Проба расплавленного металла, вз того из .тьной иечи в количестве около 500 см залив-аетс  в воронку 3, после чего включаетс  ток.A sample of molten metal, taken from a tin of about 500 cm, is poured into funnel 3, after which the current is turned on.

Спектр электрического разр да между струей металла 10 и .посто нным электродом 4 фотографируетс  спектрографом и далее по снектрограмме анализ проводитс  од}П1м из известных приемов.The spectrum of the electrical discharge between the metal stream 10 and the stationary electrode 4 is photographed by a spectrograph, and then, using a spectrogram, the analysis is carried out from one of the known methods.

Обработанна  проба стекает в трубчатую печь 8 с чугунным тигслем 9, укрепленной на той же станине 2 и вращающейс  около горизоитальпой оси дл  выливани  отработанной пробы.The processed sample flows into a tube furnace 8 with a cast iron tigle 9, mounted on the same bed 2 and rotating around a horizontal axis to discharge the spent sample.

Предмет и з о б р е т е н и  Subject and title

1. Способ спектрального анализа расплавленных металлов и сплавов с при.менением дугового разр да, отличающийс  тем, что раз . 469 р д пропускают между струей расплавленного металла и посто нным электродом. 2. Прибор дл  осуществлени  способа по п. 1, отличающийс  тем, что он состоит из воронки 3 дл  наливани  пробы жидкого металла или сплава и тигл  9 дл  приема стекающего металла, между которыми помешен электрод 4.1. A method for the spectral analysis of molten metals and alloys with arc change, characterized in that times. A 469 row is passed between a stream of molten metal and a permanent electrode. 2. An apparatus for carrying out the method according to claim 1, characterized in that it consists of a funnel 3 for pouring a sample of a liquid metal or alloy and crucibles 9 for receiving a flowing metal, between which electrode 4 is placed.
