PROBLEM TO BE SOLVED: To provide a continuous type heat treatment facility for steel strip and its combustion method with which a temperature controllability in a heating zone is improved in a transition period (in a unsteady state) changing the steel strip size, the steel strip temperature, line speed, etc., and also, carbon [C] can efficiently be oxidized and removed and further, even in a steady state, this facility can contribute to the heating of the steel strip. SOLUTION: In the continuous type heat treatment facility for steel strip and its combustion method, setting directly firing reducing burners so as to be faced to both sides interposing the steel strip at an inlet side or an intermediate side or an outlet side of the heating zone performing the heating with a radiant tube type radiation duct, the above directly firing reducing burner is ordinarily burnt to a fixed reference load, and at the transition period changing the heating cycle, the combustion load of the directly firing reducing burner is adjusted so as to compensate the heat response for heating with the radiant tube type radiation duct.
