The oxygen sensor of the oxygen probe for measuring the dissolved oxygen concentration of the molten steel

摘要

The subject innovation relates to an oxygen sensor of the oxygen probe to measure the concentration of dissolved oxygen in the molten steel for deoxidation treatment by zirconia employing a solid electrolyte as the standard electrode, the zirconia tip part of the solid electrolyte is the non-coating process, the rear end portion by a thermal shock It characterized in that the coating for preventing cracks ZrO _2.
