Drying coated metal strip by induction heating in a tunnel furnace with independent control of the temperature of the induction coils to maintain them at a higher temperature than the extracted solvents
After coating a metal strip by continuous defilement, the strip is heated by electromagnetic induction in a tunnel furnace to evaporate the solvents and assure the firing of the coating, the solvents being extracted continuously from the furnace enclosure. The surfaces (6,6') of the induction coils (3,3') opposite the strip (2) are maintained at a temperature above that of the solvents independently of the ambient temperature inside the furnace..
