Title: Using the results of tuyere coke sampling to guide blast furnace operation
Abstract:Based on data of tuyere coke sampling at No.4 BF of Shougang,the relationship between coke zone length in raceway and actual wind velocity,coke size and quality is analyzed,the relationship between co...Based on data of tuyere coke sampling at No.4 BF of Shougang,the relationship between coke zone length in raceway and actual wind velocity,coke size and quality is analyzed,the relationship between coal ratio,slag volume and coke zone length in raceway is discussed and the relationship between the permeability index and actual wind velocity,coal rate,tuyere coke zone and charging regime is researched.Suggestions for adjusting the ratio of ore to coke,upper and lower regimes are given through analyzing gas pressure difference in hearth radial direction.Thanks to implementing the suggestions,technical and economic indexes of the blast furnaces have been obviously improved.Read More
