ABSTRACT:
A method and apparatus for drying and curing a coating which as been applied in liquid form to a metal substrate. The process and apparatus include a precuring or drying of the coating by rapidly heating the sheet in an electromagnetic induction coil to volatilize solvents in the coating. The precured sheets are then immediately conveyed to a conventional convection oven for further heating the sheets by baking the sheets at a temperature and for a duration in accordance with the drying and curing specifications of the coating manufacturer. The induction coil is designed to heat the sheet metal in a narrow transverse band as the sheet moves through the induction coil. The power supply to the induction circuit is designed to permit the induction coil to be turned on under varying load.
