ABSTRACT:
A process for annealing a moving metal substrate, especially a steel sheet. The process includes providing a gas under reduced pressure facing a first side of the substrate, creating a cold plasma in the gas by means of plasma discharges between the substrate and a counter electrode, the plasma being uniformly divided over the width of the substrate, and dissipating electrical power from the plasma discharges into the substrate, resulting in a uniform distribution of the density of power over the width of the substrate and a quick and uniform heating thereof
