最近几年来,在冶炼过程中用电化学手段测试钢水中氧活度越来越普遍了。但同时也发现,在某些测试条件下测量信号常不稳定,得不到足够的重现性。在测试过程中有时因固体电解质管对温度敏感性高而产生裂纹,从而烧毁测头。 为了对钢水中氧含量的电化学测试方法进行改进,围绕下列目的进行了深入的研究工作:降低固体电解质的温度敏感性,使电解质性能达到最佳化;减少测头本身对测试结果的干扰。 试验结果,使用MgO部分稳定的ZrO_2电解质
In recent years it has become more and more common to test the oxygen activity in molten steel electrochemically during the smelting process. At the same time, however, it has also been found that the measured signal under some test conditions is often unstable and does not give sufficient reproducibility. During testing, the probe sometimes burns due to cracking of the solid electrolyte tube due to its high temperature sensitivity. In order to improve the electrochemical test method of oxygen content in molten steel, further research work has been carried out for the following purposes: to reduce the temperature sensitivity of the solid electrolyte and optimize the electrolyte performance; to reduce the interference of the probe itself to the test result. Test results, the use of MgO partially stabilized ZrO2 electrolyte
