Application of Time-of-flight Mass Spectrometer for On-line Gas Analyzing |
| |
| Abstract: | The work principle and performance characteristic of time-of-flight mass spectrometer have been introduced in this paper. The configure, installation layout and the connections with other production equipments of the converter and the performance parameters realized on situ of the on-line gas analyzing system which was used for dynamic control of 4# converter have been described. From the data of large numbers of melting processes, the relativity between the melting curve based on gas analysis results obtained by this analyzing system and the production process of the converter was analyzed. It has been shown that the on-line gas analyzing system will play an important role in dynamic control of steel-making process for its capabilities of alarming the wate r-leaking of the oxygen lance in time, decreasing the back-blowing times, improving the shooting rate of the end point determination of melting and alarming of accidents. |
