ABSTRACT:
For the annealing of steel in continuously operating units, the formation of so-called white dust is almost completely eliminated by subjecting the steel to a deoxidizing pretreatment before the annealing sequence so as to at least largely remove the oxygen adsorbed on the surface of the steel, as well as any oxygen compounds also present on the surface.
