摘　　要：精确在线测定铁水中磷的质量分数是衡量原材料质量和提高高炉工作效率的保障。为此,利用4Ca O·P2O5辅助电极和镁稳定的氧化锆固体电解质组装定磷传感器探头,采用自制的辅助电极浆料进行涂覆,并对涂覆了不同配比浆料的传感器进行多组实验。实验结果表明:辅助电极在固体电解质表面的附着力对定磷传感器性能的发挥有较为显著的影响;合理的粉体和黏结剂质量比是定磷传感器发挥作用的关键。The accurate online determination of phosphorus in the molten iron can measure the quality of raw materials and improve the blast efficiency. Thus the 4CaO. P205 auxiliary electrode and the solid ZrO2 electrolyte are used to make up the detector of inorganic phosphorus sensor. And many groups of experiments are made to the sensors coated by self-made auxiliary electrode paste of differ- ent ratios. The experimental results show that the adhesion of the auxiliary electrode on the surface of the solid electrolyte plays an important role in the performance of phosphorus sensor and a reasonable quality ratio of powder and binder is the key to the success of phosphorus sensor.
