| titleOfInvention | The rapid assay methods of calcium fluoride and calcium oxide content in steel-making desulfurizing agent |
| abstract | The invention discloses a kind of rapid assay methods of making steel with calcium fluoride in desulfurizing agent and calcium oxide content, the method is by drawing the working curve of lime stone chemical analysis standard specimen and and the working curve setting up desulfurizing agent on fluoride ion electrode measures TCaO and CaF in desulfurizing agentn 2 content, and obtain calcium fluoride and calcium oxide content fast by correlation values.The present invention can detect CaF in desulfurizing agent samplen 2 content range 0 ~ 40%, almost cover the CaF of all desulfurizing agents in production runn 2 distribution gradient, can prolonged application CaF in the desulfurizing agent of laboratoryn 2 quantitative detection.Plasma analysis TCaO Content Method substantially reduces analytical cycle, simplifies analytical procedure, and the time analyzing a Lot sample is about 40min, and chemical method analysis then needs 120min.Method is simple to operate, and accuracy is high, reproducible, and sample controls within 5min detection time.<!--1--> |
