Description
Przedmiotem wynalazku jest czujnik termoelek¬ tryczny do ciaglego pomiaru niektórych skladni¬ ków stopowych w cieklych metalach zwlaszcza wegla.The present invention relates to a thermocouple sensor for the continuous measurement of certain alloying elements in liquid metals, especially carbon.
Dotychczas pomiaru zawartosci wegla w cieklej stali dokonuje sie posrednio przez okreslanie za¬ wartosci tlenu zmierzonej przy pomocy ogniwa stezeniowego. Ogniwa stezeniowe nie nadaja sie do przeprowadzania ciaglego pomiaru, sa one bowiem z reguly wykonywane jako czujniki jednorazowego uzytku do pomiarów chwilowych. Natomiast czuj¬ ników do pomiaru zawartosci innych pierwiastków w cieklych metalach nie stosuje sie.Hitherto, the measurement of the carbon content of liquid steel is done indirectly by determining the oxygen content measured with a concentration cell. Concentration cells are not suitable for continuous measurement, as they are usually made as disposable sensors for instantaneous measurements. By contrast, sensors for measuring the content of other elements in liquid metals are not used.
Czujnik termoelektryczny wedlug wynalazku do ciaglego pomiaru niektórych skladników stopowych w cieklych metalach, sklada sie z dwóch pomiaro¬ wych, metalowych elektrod umieszczonych w rurze z materialu nieprzewodzacego prad elektryczny, korzystnie ceramicznego.The thermoelectric sensor according to the invention for the continuous measurement of certain alloying elements in liquid metals consists of two measuring metal electrodes placed in a tube made of a non-conductive material, preferably ceramic.
W elektrodach umieszczone sa termopary, które sluza do regulacji takiego przeplywu medium chlo¬ dzacego, aby miedzy elektrodami pomiarowymi utrzymywala sie stala róznica temperatur. Dwie z jednakowych galezi termopar polaczone sa z mi- liwoltomierzem, który mierzy wynikajaca z róznicy temperatur miedzy elektrodami, proporcjonalna na przyklad do zawartosci wegla w cieklej stali sile termoelektryczna.Thermocouples are placed in the electrodes, which are used to regulate the flow of the cooling medium in such a way that a constant temperature difference is kept between the measuring electrodes. Two of the same thermocouple branches are connected to a millivoltmeter which measures a thermoelectric force proportional to the carbon content of the liquid steel, resulting from the temperature difference between the electrodes.
Czujnik wedlug wynalazku jest prosty w kon- 2 strukcji i pozwala na ciagly pomiar zawartosci wegla z duza dokladnoscia.The sensor according to the invention is simple to construct and allows the continuous measurement of the carbon content with high accuracy.
Wynalazek pokazano w przykladzie wykonania na rysunku. Dwie pomiarowe, metalowe elektrody 2 5 umieszczone sa w rurze 1 z ceramiki. W elektro¬ dach 2 znajduja sie termopary 5 które sluza do regulacji takiego przeplywu medium chlodzacego 3, aby miedzy elektrodami utrzymywala sie stala róznica temperatur. Galezie termopar 5 polaczone 10 sa z miliwoltomierzem 4, który mierzy wynikajaca z róznicy temperatur miedzy elektrodami, propor¬ cjonalna na przyklad do zawartosci wegla w cieklej stali sile termoelektryczna. Regulacje wlasciwego przeplywu medium chlodzacego 3 zapewnia regu- 15 lator 6 sterujacy pompe 7. Do utrzymywania okres¬ lonej temperatury medium chlodzacego sluzy chlod¬ nica 8.; Zatstrzezenie patentowe Czujnik termoelektryczny do ciaglego pomiaru a, zawartosci niektórych skladników w cieklych me¬ talach, zwlaszcza wegla, znamienny tym, ze sklada sie z dwóch pomiarowych, metalowych elektrod (2) umieszczonych w rurze (1) z materialu nieprzewo¬ dzacego prad elektryczny, korzystnie ceramicznego, 25 przy czym w elektrodach (2) znajduja sie termo¬ pary (5) które sluza do regulacji takiego przeplywu medium chlodzacego (3) aby miedzy elektrodami pomiarowymi utrzymywala sie stala róznica tem¬ peratur, a galezie termopar (5) polaczone sa z mili- 30 woltomierzem (4). 109 513109 513 ÓZGraf. Z.P. Óz-wo, z. 1267 (105+20) 3.81 Cena 45 zlThe invention is shown in an exemplary embodiment in the drawing. Two metal measuring electrodes 2 5 are placed in the ceramic tube 1. In the electrodes 2 there are thermocouples 5 which serve to regulate such a flow of the cooling medium 3 so that a constant temperature difference is maintained between the electrodes. The thermocouple branches 5 are connected to a millivoltmeter 4 which measures a thermoelectric force proportional to, for example, the carbon content of the liquid steel, as a result of the temperature difference between the electrodes. The regulation of the proper flow of the cooling medium 3 is ensured by the controller 6 which controls the pump 7. The cooler 8 serves to maintain a certain temperature of the cooling medium; Patent claim Thermoelectric sensor for continuous measurement of the content of certain components in liquid metals, especially carbon, characterized by the fact that it consists of two measuring, metal electrodes (2) placed in a tube (1) made of a material not conducting electricity, preferably ceramic, with the electrodes (2) having thermocouples (5) which are used to regulate the flow of the cooling medium (3) so that a constant temperature difference between the measuring electrodes is maintained, and the thermocouple branches (5) are connected with milli- voltmeter (4). 109 513 109 513 ÓZGraph.
