  • Patent number: 11702718
    Abstract: A method of making a soft magnetic intermediate product of metal with particularly good magnetization behavior, the method comprising the following method steps: production or provision of a metallic, rollable blank of a metallic product, preliminary rolling of the metallic blank with a defined degree of deformation to an intermediate thickness, the degree of deformation being matched to a critical or postcritical degree of rolling to be observed during subsequent rolling, heat treatment of the prerolled blank, preferably annealing of the prerolled blank, rolling of the blank with a critical or postcritical degree of rolling to a final thickness and subsequent annealing to set a defined grain size and finishing of the intermediate product.
    Type: Grant

  • Patent number: 9045829
    Abstract: A process produces a coated metal strip from a semi-finished strip, in which the semi-finished strip is reeled off a coil. A corrosion protection layer is then applied to the semi-finished strip and the coated semi-finished strip is then reeled up to form a coil. The semi-finished strip is a cold-rolled strip obtained by cold rolling, cooling and recrystallization annealing. A medium containing metallic particles is applied to form the corrosion protection layer. The medium is a wet-chemical solution which is applied by spraying, dipping, squirting, flooding or rolling. The corrosion protection layer is dried on the cold-rolled strip by supplying heat at a temperature below the recrystallization annealing temperature of the cold-rolled strip after application of the medium and before reeling-up.
