【Abstract】 The amount of oxygen accumulated in BOF is obtained from the off-gas analysis, Mathematical models for predicting w[P]t and w[Mn]t at the end of blowing are established through analyzing this parameter with reaction equilibrium and mass balance. Through the comparison between the values of model calculation and practical measurement, the following conclusions are obtained: w[P]t and w[Mn]t at the end of blowing can be predicted by w[P]t and w[Mn]t respectively based on the off-gas analysis.更多还原
