PROBLEM TO BE SOLVED: To provide a gas supplying system in a steel mill with which discharging of converter gas is unnecessary in the steel mill. SOLUTION: The gas supplying system 100 in the steel mill, as the converter gas system, is provided with; converter gas upstream side piping 12 for transporting the converter gas from the converter 11; a converter gas holder 14; converter gas downstream side piping 15 for supplying the converter gas to a converter gas combustion facility 17; a combustion exhausting tower 13; and a blower 16. This system as a blast furnace gas system, is provided with: blast furnace gas upstream side piping 22 for transporting the blast furnace gas from the blast furnace 21; a blast furnace gas holder 24; blast furnace gas downstream side piping 25 for supplying the blast furnace gas to a blast furnace gas using facility 27; and a calory meter 26. In this system as a communicating system, communicating piping 31 for communicating the downstream side position from the blower 16 in the converter gas downstream side piping 15 and the upstream side position from the calory meter 26 in the blast furnace gas downstream side piping 25 are installed, and in the communicating piping 31, a flowing rate adjusting valve 32 and a flowing rate meter 33 are installed.
