Abstract
A method of drying and/or curing an organic coating on a continuously running metal strip, includes heating the strip by electromagnetic induction in a tunnel furnace having an enclosure with hot internal walls and heating the enclosure. The heating of the strip by electromagnetic induction is coupled with heating by infrared radiation and heating by convection with a combustion gas. The heating of the enclosure of the furnace is performed by convection using the same combustion gas used for heating the strip by convection. A device for implementing the method is also provided.
