摘要： A method for passivation of the surface of blackplate or tinplate by electrolytic deposition of a chromium oxide-containing passivation layer on the surface. The electrolytic deposition of the chromium-containing passivation layer occurs from an electrolyte solution that contains a trivalent chromium compound as well as at least one salt to increase the conductivity and at least one acid or a base to adjust a desired pH value. The electrolyte solution contains no additional components apart from the trivalent chromium compound as well as the at least one salt and the at least one acid or base and is especially free of organic complexing agents and free of buffering agents.

摘要： A method of removing a coating made of an organic material, in particular an organic lacquer or a polymer coating, which adheres to the surface of tin-plated sheet steel. In a first step, the tin layer of the tin-plated sheet steel is completely or incipiently melted by exposure to electromagnetic radiation with a predefined wavelength, to which the organic coating is at least primarily transparent, with the organic coating becoming detached from tin layer, and in a second step, the organic material of the coating which detached from the tin layer is removed.

摘要： A process for passivation of strip steel plate, having the following steps: electrochemical treatment of the black plate by passing the black plate through an electrolyte to form an inert steel surface; rinsing the black plate; and application of an aqueous chromium-free treatment solution to at least one surface of the black plate to form a conversion layer that protects against corrosion and an adhesion layer for paints and organic coating materials. The black plate treated in accordance with this process is characterized by high corrosion resistance and has good bonding capacity for paints and organic coatings and therefore is very suitable as a substitute for tin-free steel (TFS or ECCS) and tinplate for the production of packagings, in particular cans. In contrast to the traditional manufacturing and passivation processes for tin-free steel and tinplate, no chromium VI, which is environmentally hazardous and hazardous to health, is used in this process.

摘要： A method for coating a steel sheet with a metal layer includes the following steps: application of a first thin metal layer as a flash coating; melting the metal layer from the flash coating; and application of at least one additional metal layer onto the metal layer from the flash coating. To increase the corrosion resistance of the coated steel sheet and to improve the energy and resource efficiency of the coating method, with which a steel sheet having a high corrosion resistance and good weldability and with a good deep drawing and ironing behavior is to be produced, the thickness of the metal layer from the flash coating is at most 200 mg/m2 and the metal layer from the flash coating is melted with electromagnetic radiation of high energy density.

摘要： A method for producing a steel sheet for packaging includes: cold-rolling a hot-rolled steel sheet made from a steel having a carbon content of 10 to 1000 ppm by weight, the steel of the hot-rolled steel sheet having a predetermined recrystallization temperature (TR); heating the cold-rolled steel sheet to a predetermined heating temperature (TE), where TR≤TE, the heating performed at least partially in the presence of a nitrogen donor at least until TR is reached such that when the cold-rolled steel sheet is heated, nitrogen from the nitrogen donor is diffused at least into a near-surface region of the cold-rolled sheet steel and incorporated in the near-surface region, as a result of which the TR in the near-surface region is increased by a value ΔT, where TE

摘要： A method for inspection of a surface of a sheet moving in a direction, in which the surface is illuminated with first and second light sources, with the first light source emitting light under a first incidence angle range onto a first surface area and the second light source emitting light under a second incidence angle range onto a second surface area of the surface of the sheet. The first and second light sources are operated in pulsed fashion in alternation with a stipulated pulse frequency so that the surface of the sheet is illuminated in alternation with the pulse frequency in the first surface area and the second surface area and the first surface area illuminated by the first light source is observable by an inspector via a mirror in the bright field and the second surface area illuminated by the second light source is observable by the inspector via the mirror in the dark field.

摘要： A reflector for helio-thermal systems may include a metallic carrier plate and a reflective coating that is applied to the carrier plate and is constructed from at least one metallic reflective layer and at least one protective layer applied to the reflective layer. Such reflectors have high reflective capabilities, are robust in relation to mechanical stress, and can be manufactured cost effectively. Such reflectors are also lightweight and dimensionally stable due to the fact that the carrier plate may be formed from a sandwich plate having at least one nonmetallic intermediate layer disposed between an upper and lower metallic cover plate. The upper cover plate may have a smoothed surface to which the reflective layer can be applied. The smoothed surface prior to the reflective layer being applied may have an arithmetic mean surface parameter Ra of less than 0.03 μm. Methods for manufacturing such reflectors are also disclosed.
