Modern requirements for the quality indicators of hot rolled sheet steel are associated with maintaining high flatness of sheet metal during further processing by high-tech methods, for example, by laser or plasma cutting. When laser cutting a sheet

The final stage in the production of hot rolled steel is leveling on roller levelers under cyclic alternating deformation. When laser cuts a sheet, it may bend due to the release of residual stresses that are unevenly distributed over the volume. The
