采用质谱分析仪对转炉炉气进行在线检测分析,并采用炉气分析模型进行拟合及与实测结果进行比较,通过分析炉气中CO和CO2的变化规律,结果表明:应用指数模型能够较好的预报终点碳含量;三次方模型能够更好的反应转炉冶炼后期熔池中碳含量。 The mass spectrometer was used to detect and analyze the converter gas on-line. The gas-gas analysis model was used for fitting and compared with the measured data. By analyzing the change rules of CO and CO2 in the gas, the results show that the application of index model can be better Of the forecast carbon content of the endpoint; cubic model can better reflect the late furnace smelting furnace carbon content.
