Abstract: As plicated factors can affect the gas flow distribution which is hard to be elaborated, an evaluation
indicator system of gas flow distribution was proposed according to the characters of the gas distribution during the
process of blast furnace (BF) production. An extension evaluation model of the performance of gas flow distribution was
implemented, by which the gas distribution performance in BF was evaluated using extension set theory with both the
quantitative calculation and qualitative analysis methods. The reasonable gas distribution was determined quantitatively
and the research results indicate that the mod
