| 摘 要： | 氧在钢液中的传质对固体电解质氧浓差电池测定钢液中氧含量的影响,并通过实验验证了钢液中氧传质的存在,通常测氧探头所测为探头与钢液界面之氧浓度,为知钢液本体真实氧浓度,可通过实际测定数值回归而求得。

| Abstract: | An expression showing the dependence of bulk oxygen concentration, %O]b, and oxygen concentration at the liquid-solid electrolyte interface, %O]i, has been derived aswhere A and B-- characteristic quantities determined by ionic conductance and geometic shape of the solid electrolyte used and the condition of oxygen mass transfer in the liquid steel.A simple experiment was conducted to show the existence of oxygen mass transfer in liquid steel during the EMF measurement with solid electrolyte (ZrO2) cells, |
