Abstract: A method for producing a corrosion-resistant steel sheet made of an unalloyed or low-alloy and cold-rolled steel having a carbon content of less than 0.1 wt %. The method includes the following steps: applying a metal coating to the steel sheet; annealing the coated steel sheet in a recrystallizing manner by heating the coated steel sheet to temperatures in the recrystallization range by electromagnetic induction in an inert-gas atmosphere; and quenching the coated and annealed steel sheet. The metal coating is fused on during the recrystallization annealing.

Abstract: The invention relates to a method for producing packaging steel consisting of a cold-rolled steel sheet made of unalloyed or low-alloy steel having a carbon content of less than 0.1%. In order to provide high-strength packaging steel that has good formability and high corrosion resistance and can be produced in as energy-saving a manner as possible, the steel sheet according to the invention is first coated with a metallic coating and then annealed in a recrystallizing manner at a heating rate of more than 75 K/s and preferably more than 100 K/s to temperatures of more than 700° C., such that the metallic coating melts. The coated and annealed steel sheet is then quenched to normal temperature at a cooling rate of at least 100 K/s.

In order to provide high-strength packaging steel that has good formability and high corrosion resistance and can be produced in as energy-saving a manner as possible, the steel sheet according to the invention is first coated with a metallic coating and then annealed in a recrystallising manner at a heating rate of more than 75 K/s and preferably more than 100 K/s to temperatures of more than 700° C., such that the metallic coating melts. The coated and annealed steel sheet is then quenched to normal temperature at a cooling rate of at least 100 K/s.

Abstract: 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.
