| Abstract: | The paper presents an analysis of the iron content in continuous casting protective slag by means of a new phenanthroline spectrophotometric method. The optimizing analysis conditions were ob tained by a number of condition experiments on samples dissolving, interference of coexisting irons and color development reaction and a number of protective slag samples were measured, with the result that the measured values were well consistent with the reference ones, and that the relative standard deviations （RSD） were smaller than 2%. As a result, this method can fully meet the requirements of determination of iron content in the continuous casting protective slag. |
