Construction and testing of probes for oxygen measurement in steel melts; Aufbau und Erprobung von Sonden zur Sauerstoffmessung in Stahlschmelzen

Abstract

The Central Institute of Nuclear Research (ZfK) Rossendorf developed oxygen probes for measurements in steel melts in cooperation with industrial plants and participated in their production and testing. The steps of investigation and development of the oxygen probes were development of ceramics, assembling of the sensor, and manufacturing of oxygen probes. In the result of the development a MgPSZ-ceramics was obtained which met all requirements for application in steel melts (strength, thermal shock resistence). The reference mixture applicated in this sensor distinguishes by a rapid potential formation. The oxygen sensors were tested in laboratory melts whereas the complete oxygen probes were operated in steel plants. The general measuring behaviour of the sensors could be demonstrated in the laboratory tests. The quantitative determination of the measuring parameters was obtained by comparative measurements in steel plants. The determination of high oxygen activities causes no troubles and the standard deviation of the cell voltage was within a {+-}6 mV range. At lower oxygen activities the measurements showed greater differences and require further improvement. (orig.).

[Deutsch] Das ZfK Rossendorf hat in Zusammenarbeit mit der Industrie Sonden zur Sauerstoffmessung in Stahlschmelzen entwickelt und sich bei der Herstellung und Erprobung dieser beteiligt. Die untersuchten und optimierten Schritte zur Sondenherstellung waren: Keramikherstellung, Sensormontage und Sondenfertigung. Im Ergebnis der Keramikentwicklung wurde eine MgPSZ-Keramik erhalten, die den Anforderungen der Messung in Stahlschmelzen (Festigkeit, Thermoschockbestaendigkeit) voll entsprach. Das fuer die Sensormontage entwickelte Referenzgemisch zeichnet sich durch eine schnelle Potentialeinstellung aus. Die Erprobung der Sensoren erfolgte in Laboranlagen, waehrend die fertigen Sonden nur im Stahlwerk getestet werden konnten. Die generelle Messbereitschaft der Sensoren konnte an den Laboranlagen nachgewiesen werden. Die quantitative Bestimmung der Messparameter erfolgte bei Vergleichsmessungen im Stahlwerk und hatte folgendes Ergebnis: Die Messungen hoher Sauerstoffgehalte bereiteten mit den entwickelten Sonden keine Probleme und hatten eine Exemplarstreuung von {+-}6 mV. Bei den Messungen niedriger Sauerstoffaktivitaeten waren die Abweichungen noch zu gross, so dass weitere Verbesserungen noetig sind. (orig.).}
