PROBLEM TO BE SOLVED: To provide a steel heating facility capable of burning/treating unburned exhaust gas generated from a low air ratio heating furnace by a less auxiliary fuel at low cost/low environment load. SOLUTION: When the steel is heated in non-oxidation atmosphere of combustion air ratio of less than 1.0, a tubular flame burner is arranged as a combustion device for perfectly burning/treating the unburned exhaust gas generated from the heating furnace at the outside of the furnace. The steel heating facility has an operation mechanism 26 for operating a flow rate and calorie of the unburned exhaust gas generated from the heating furnace from a kind of the fuel fed to the heating burner 13 of the heating furnace 11, a flow rate, a flow rate of air and an air ratio; and an air flow rate adjustment mechanism 27 for determining a flow rate of air fed to the tubular flame burner from the flow rate and the calorie of the unburned exhaust gas.
