本文介绍一批及分批顶加碳酸钠系,碳酸钠—氧化铁系及碳酸钠—氧化钙系处理剂,对含钒铁水进行钠化处理。用氧化锆基固体电解质氧浓差电池连续测定铁水内及渣—铁界面氧位,获得氧位变化与铁水各元素含量及其脱除速率的良好对应关系,反映各元素脱除反应进行的地点、方向和程度,判明是界面反应。尝试以“耦合”反应动力学模型进行动力学简析。测定界面氧位理论上、实际上都有意义,在工业技术上是可行的,可藉此监察处理过程和控制处理终点。界面氧位也反映出处理剂性能及加入方式,应选择能使界面氧位尽可能高,并且高氧位持续时间尽量长的处理剂及加入方式。
This article describes a number of batches and batches top plus sodium carbonate, sodium carbonate - iron oxide and sodium carbonate - calcium oxide treatment agent, the vanadium-containing molten iron sodium treatment. Continuous determination of the oxygen content in the molten iron and the slag-iron interface by a zirconia-based solid electrolyte oxygen concentration cell obtained a good correspondence between the variation of the oxygen concentration and the content of each element of the molten iron and the removal rate thereof, and reflected the location of each element removal reaction , Direction and degree, identified as the interface reaction. Attempt to conduct kinetic analysis with “coupled” kinetic model. Measuring the oxygen level of the interface theoretically, in fact, makes sense, is technically feasible in the industry to monitor the process and control the end of the process. The interface oxygen level also reflects the performance of the treatment agent and the mode of addition. The treatment agent and the addition mode should be chosen to maximize the oxygen level in the interface and maximize the duration of the hyperoxia.
