A Temperature Prediction Model of Converters Based on Gas Analysis

Gas analysis technology, which can continuously predict temperature in converters with long life, is applied on different tongue of converters as it has no restriction to the glory hole of converters. In this research, the real-time detection of the composition of gas exhaust from converters is provided by gas analyzer, and a model based on thermodynamic equilibrium and the improvement of Wan XueFeng's gas analysis model is built to give an online prediction of the temperature in converters. The curve of modified model is stable and the deviation between calculated value and measured value is minute so that it can truly reflect the status of converters.
