| titleOfInvention | The sulfur method of molten iron |
| abstract | A kind of sulfur method of molten iron, when the desulfurization process of molten iron, the S concentration of the sample that more than at least 1 phase analysis in before desulfurization process, after process neutralisation treatment is extracted from molten iron, based on the assay value of this S concentration, carry out thereafter desulfurization further, judge that desulfurization terminates or determines desulfurization condition thereafter.In the sulfur method of this molten iron, by analyzing fast and accurately the S concentration in molten iron, control the S concentration after desulfurization process accurately, thus, prevent S concentration deviation, and the operation in the cost increase caused that prevents excessive desulfurizing agent from adding, steel operation processed upsets.The analytical approach of above-mentioned S concentration comprises following operation: under pure oxygen atmosphere, by high-frequency induction heating, sample is oxidized, and the S in molten iron is made SOn 2 high-frequency induction heating operation; Ultraviolet fluorescence method is used to contain SO to what generate in above-mentioned high-frequency induction heating operationn 2 gas carries out analyzing and the analysis procedure of S concentration in quantitative sample. |
