Abstract：RH vacuum degassing process has recently been more and more widely applied domestically to the smelting of high-quality steel due to its powerful function and significant technology effect. The application of mass spectrometry gas analysis system for online analysis of gas composition during RH process combined with flow and temperature control technology may realize the process optimization and end control of RH process. Composition, installation layout, analysis performance and on-spot working mode of the mass spectrometry gas analysis system adopted by the RH process of The Second Steel Smelting and Rolling Plant of Anyang Iron and Steel Group Co., Ltd. were described in the paper. In addition, the gas analysis system was tested with oxygen blowing decarburization process, decarburization treatment process without oxygen blowing and degassing process. Results indicated that the system was capable of reflecting the composition change with time during the process in a real-time, consistent and accurate way. The total latency time for 60m sampling distance was less than 40s and gas composition change process was completely consistent with the process. It is predicted that the adoption of gas analysis technology may provide evidence for the end control of RH refining process and the real-time process adjustment to cut RH smelting time and improve quality.
