Abstract: An improved process and/or system for coating of a metal strip includes means for continuous travel of the strip and a chamber for substantially completely enclosing the strip beyond an area for application of a mixture of coating and solvent. In that chamber is at least one induction coil for induction heating the strip to drive off the solvent, means for introducing substantially pure nitrogen near opposite ends of the travel of the strip therein and in between the places of introduction of the substantially pure nitrogen means for removing the resultant mixture of nitrogen and solvent which mixture is then at least largely separated into its components and reclaimed nitrogen brought back into the chamber at locations between the location of removal of the mixture and the respective locations of introduction of substantially pure nitrogen. The temperature of the interior atmosphere of the chamber is automatically maintained at a predetermined temperature preferably within the range between about 300.degree. F. and 600.degree. F. and at all events about 300.degree. F. or greater.
