Study and Application of Burden Distribution Model for Bell-less BF

Burden distribution model for bell-less blast furnace(BF) is established based on mathematical knowledge and computer technology through the analysis of effect factors and characters of burden distribution.The model is applied in the 450 stere BF in some steel company.The on-line surveillance of burden distribution process in blast furnace is implemented through the burden distribution model.The model can also direct the operators to coordinate the burden distribution reasonably.Consequently the model can improve the breathability exponential of the burden distribution in BF,decrease the ratio of coke and improve the smelting states in BF.Monitoring the burden distribution in blast furnace plays an important role to optimize the operation of blast furnace.
