    • PURPOSE: A method for measuring change of gases in a blast furnace is provided to maintain stable environment in a blast furnace by promptly judging whether or not distribution of gases in a blast furnace is changed depending on an objective judgement ground. CONSTITUTION: A method for measuring change of gases in a blast furnace comprises the steps of selecting a standard operation data which can be compared with an actual operation data measured at the blast furnace, calculating a degree of change (ΔXi) by comparing an actual operation data (X) measured at the blast furnace with a standard data (Xstd) using the following Formula 1, calculating a change index (DX) of gases in a blast furnace using the following Formula 2 by a degree of change (ΔXi) between the actual operation data and the standard operation data, and a charging mode change step which charging materials are charged by controlling an O/C of charging materials (a ratio of ore and coke) according to the change index (DX) of the gases. Formula 1 is ΔXi=(X-Xstd)/a, where ΔXi is a degree of change of operation data, X is actual operation data, Xstd is standard operation data, and a is an allowable change range. Formula 2 is DX=Σ(Si·ΔXi), where Si is a proportional index, and ΔXi is a degree of change of each operation data.
