Abstract

An annealing process of a stainless steel band, after exposure to at least one first rolling step, comprises heating under reducing atmosphere the stainless steel band, cooling the stainless steel band, and printing on its surface a roughness onto the stainless steel band. Independent claims are also included for: (A) an annealing device for implementing the inventive method, comprising a mechanism for heating under reducing atmosphere the stainless steel band, a mechanism for cooling the stainless steel band, and a rolling device for printing on the surface a roughness on the stainless steel band; and (B) use of the inventive annealing process in a rolling process such as an intermediate annealing process intended for softening the material and restoring the ductility of the stainless steel band, or in a rolling process such as a final annealing process.
