【Abstract】 A mathematical model has bon developed by using the distributjon of furnace roof gas,the properties of raw fuel and the parameters of blast. The model is employed to determine form and position of cohesive zone,so that it is enabled to grasp in time the operating state of BF,having some practical values for the BF operation improvement. It will play a progressively larger roll in the production with the technical progression of BF and further improvement and trace of the model.更多还原
