The invention relates to a cyclic baking method of an enamelled wire and an oven for realizing the method. According to the method, after an enamelled wire attached with painted liquid enters a hearth through an inlet entrance of an oven, the painted liquid, which is under the effect of an inner temperature of the oven, starts to be evaporated to generate a certain amount of solvent vapor; the solvent vapor is conveyed to a first level catalytic combustor for combustion so as to generate high temperature airflows, wherein the temperature of the airflows is higher than the temperature that is required by the technology; and one part of high temperature airflows directly pass through an air distribution device and a voltage stabilization device and are conveyed to a baking channel to bake the enamelled wire; and the other part of high temperature airflows are sent to a heat exchanger for heat exchange and then the airflows is discharged from an exhaust gas flue; and the heat exchanger absorbs waste heat of the exhaust gas and the absorbed waste heat is sent to the baking channel at the inlet entrance for baking the enamelled wire. According to the invention, the structures of the devices employed in the invention are simple; an enamelling production efficiency is high; there are no limits for production specifications and varieties; power consumption is reduced; and energy is saved and the environment is protected.
