NOVELTY - The oven has an oven unit (2) arranged in a space surrounded by a shell (3) and arranged with a heating device (21), an oven main body (22), a variable frequency exhaust fan (23), a frequency conversion blower (24), a variable frequency new fan (25) and a ventilation space (26), where the oven main body is surrounded by an area baffle plate (221). An upper end of an outlet is connected with the variable-frequency exhaust fan. The lower end is connected to the frequency converter. The oven main body is arranged in the middle end of the shell. The lower portion of the air inlet is not in communication with the shell to form the ventilation space. The lower portion and the shell are not in contact with each other to form a frequency-conversion blower. USE - Graphene oven for a coiled material. ADVANTAGE - The oven ensures that the oven unit is independent from each other when controlled by the controller so as to realize independent control of the oven unit and ensure that the abnormality in the single oven unit does not affect the product in other oven units. The oven adjusts the exhaust and fresh air amount according to the change of the different temperature of the product so as to increase the stability of product and reduce the time of manufacturing process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for utilizing a graphene oven for a coiled material. DESCRIPTION OF DRAWING(S) - The drawing shows a front sectional view of a graphene oven. 2Oven unit 3Shell 23Variable frequency exhaust fan 26Ventilating space 28Oven temperature detectors 29Ventilation temperature detectors 31Air inlet 32Air outlet 221Area baffle plate 222Leakage-proof grid 223Tray 224Air guide plate
