摘要： A continuous heat treating furnace in which heat is efficiently recovered from the combustion exhaust gas from the heating section of a continuous annealing furnace. The continuous annealing furnace of the metal strip is a heating furnace or a heating device provided with plural burners for heating to a predetermined temperature a steel material or a continuously supplied metal strip by means of combustion of the burners; a regenerative heat exchanger for collecting a sensible heat of a combustion exhaust gas of the burners, reserving the heat in a regenerator and supplying a predetermined gas to the regenerator to recover the heat to the predetermined gas; and a preheating section for blowing the predetermined gas from the regenerative heat exchanger to the metal strip for preheating. The heat exchanger body is divided into at least three sections, each section having a regenerator. When the heat exchanger body is continuously or intermittently rotated, each section is provided with a path for successively repeating to pass a heating section combustion exhaust gas for applying a sensible heat of exhaust gas to the regenerator, a purging gas for removing debris sticking to the regenerator when applying the sensible heat of the heating section exhaust gas and a circulating gas for collecting the sensible heat of the regenerator and blowing the heat to the metal strip passing the preheating section to raise a temperature of the metal strip.
