Application of Bosh Gas Volume Index and Permeability Resistance Coefficient in Masteel No.2 BF
In this paper,the application of the bosh gas volume index XBG and the permeability resistance coefficient K are discussed.By tracking and analyzing the production data of Masteel No.2 BF for over one year,it is known that BF runs stably and smoothly,and the fuel rate keeps stable when the XBC is controlled at 63-64m/min,and the corresponding bosh gas volume VBG remains at 6300-6400m3/min.Considering the conditions of the No.2 BF,such as thick slag skull and the low temperature at the bosh,it is suggested to keep the blast pressure at the level close to the upper limit,and keep the actu-al K value at 4.25-4.75 because the furnace running status is quite good in such a case.Both the bosh gas volume index and the permeability resistance coefficient are deemed as the comprehensive operating parameters,which can be used to judge the furnace conditions and intensified smelting level in BF daily operation to ensure stable and smooth running of the furnace and to improve the techno-economic indicators of the furnace.
