The invention discloses a box-type annealing furnace and an annealing method using the same. According to the box-type annealing furnace and the annealing method using the same, an arranged power chamber disturbs air flow, supplied air passes through a thermal power chamber, a heating device is arranged in the thermal power chamber, the air flow passes through a workpiece chamber after being heated to heat a workpiece in the workpiece chamber, the air flow flows back through an air flue, and a circulating flow channel is formed; the method that heating or cooling is achieved through air flow motion has the advantages that the temperature zone in the annealing furnace is more uniform, the temperature increasing and lowering speed of the annealing furnace is high, stable and controllable, the annealing efficiency is high, and a temperature control system of the annealing furnace is accurate and reliable. The box-type annealing furnace and the annealing method using the same are suitable for the field of annealing equipment.
